数据库环境

创建一个存放书籍数据的数据库表

CREATE DATABASE `ssmbuild`;

USE `ssmbuild`;

DROP TABLE IF EXISTS `books`;

CREATE TABLE `books` (
`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
`bookName` VARCHAR(100) NOT NULL COMMENT '书名',
`bookCounts` INT(11) NOT NULL COMMENT '数量',
`detail` VARCHAR(200) NOT NULL COMMENT '描述',
KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8

INSERT  INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES 
(1,'Java',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');

基本环境搭建

1、新建一Maven项目！ssmbuild ， 添加web的支持

2、导入相关的pom依赖！

<dependencies>

    </dependency>
</dependencies>

3、Maven资源过滤设置

<build>
   <resources>
       <resource>
           <directory>src/main/java</directory>
           <includes>
               <include>**/*.properties</include>
               <include>**/*.xml</include>
           </includes>
           <filtering>false</filtering>
       </resource>
       <resource>
           <directory>src/main/resources</directory>
           <includes>
               <include>**/*.properties</include>
               <include>**/*.xml</include>
           </includes>
           <filtering>false</filtering>
       </resource>
   </resources>
</build>

4、建立基本结构和配置框架！

java目录 下建立四个包

com.qiu.pojo
com.qiu.dao
com.qiu.service
com.qiu.controller

mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
       PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
       "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

</configuration>

applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">

</beans>

Mybatis层编写

1、数据库配置文件 database.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456

2、IDEA关联数据库

3、编写MyBatis的核心配置文件

<?xml version="1.0" encoding="UTF-8" ?>
        <!DOCTYPE configuration
                PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
                "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <settings>
        <!--开启Mybatis日志-->
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings>
    <typeAliases>
        <!--修改对应实体类包-->
        <package name="com.qiu.pojo"/>
    </typeAliases>
    <mappers>
        <mapper resource="com/qiu/dao/BookMapper.xml"/>
    </mappers>
</configuration>

4、编写数据库对应的实体类 com.qiu.pojo.Books

使用 lombok 插件！

package com.qiu.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@NoArgsConstructor
@AllArgsConstructor
@Data
public class Books {
    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;
}

5、编写Dao层的 Mapper 接口！

package com.qiu.dao;
import com.qiu.pojo.Books;
import org.apache.ibatis.annotations.Param;
import java.util.List;
public interface BookMapper {
    //增加一本图书
    int addBook(Books books);
    //删除一本图书
    int deleteBook(@Param("bookId") int id);
    //更新一本图书
    int updateBook(Books books);
    //查询一本图书
    Books queryBookById(@Param("bookId") int id);
    //查询全部的图书
    List<Books> queryAllBook();
    //根据书名查询图书
    List<Books> queryBookByName(@Param("bookName") String bookName);
}

6、编写接口对应的 BookMapper.xml 文件。需要导入 MyBatis 的包；

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.qiu.dao.BookMapper">
    <insert id="addBook" parameterType="Books">
        insert into ssmbuild.books (bookName, bookCounts, detail)
        values (#{bookName}, #{bookCounts}, #{detail});
    </insert>

    <delete id="deleteBook" parameterType="int">
        delete from ssmbuild.books where bookID = #{bookId};
    </delete>

    <update id="updateBook" parameterType="Books">
        update ssmbuild.books
        set bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail}
        where bookID = #{bookID};
    </update>

    <select id="queryBookById" parameterType="_int" resultType="Books">
        select * from ssmbuild.books where bookID = #{bookId};
    </select>

    <select id="queryAllBook" resultType="Books">
        select * from ssmbuild.books;
    </select>

    <select id="queryBookByName" parameterType="java.lang.String" resultType="Books">
        select * from ssmbuild.books where bookName like concat('%',#{bookName},'%')
    </select>
</mapper>

7、编写 Service 层的接口和实现类

接口：

package com.qiu.service;
import com.qiu.pojo.Books;
import java.util.List;
public interface BookService {
    //增加一本图书
    int addBook(Books books);
    //删除一本图书
    int deleteBook(int id);
    //更新一本图书
    int updateBook(Books books);
    //查询一本图书
    Books queryBookById(int id);
    //查询全部的图书
    List<Books> queryAllBook();
    //根据书名查询图书
    List<Books> queryBookByName(String bookName);
}

实现类：

package com.qiu.service;
import com.qiu.dao.BookMapper;
import com.qiu.pojo.Books;
import java.util.List;
public class BookServiceImpl implements BookService {
    //调用dao层的操作，设置一个set接口，方便Spring管理
    private BookMapper bookMapper;
    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }

    public int addBook(Books books) {
        return bookMapper.addBook(books);
    }

    public int deleteBook(int id) {
        return bookMapper.deleteBook(id);
    }

    public int updateBook(Books books) {
        return bookMapper.updateBook(books);
    }

    public Books queryBookById(int id) {
        return bookMapper.queryBookById(id);
    }

    public List<Books> queryAllBook() {
        return bookMapper.queryAllBook();
    }

    public List<Books> queryBookByName(String bookName) {
        return bookMapper.queryBookByName(bookName);
    }
}

底层需求操作编写完毕！

Spring层编写

1、配置Spring整合MyBatis，我们这里数据源使用c3p0连接池；

2、我们去编写Spring整合Mybatis的相关的配置文件；【spring-dao.xml】

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">

    <!--1.关联数据库配置文件-->
    <context:property-placeholder location="classpath:database.properties"/>
    <!--2.连接池-->
    <!--
        dbcp:半自动化操作，不能自动连接
        c3p0:自动操作（自动化的加载配置文件，并且可以自动设置到对象中！）
        druid
        hikari
    -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
        <!--c3p连接池的私有属性-->
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
        <!--关闭连接后不自动commit-->
        <property name="autoCommitOnClose" value="false"/>
        <!--获取连接超时时间-->
        <property name="checkoutTimeout" value="10000"/>
        <!--当获取连接失败重试次数-->
        <property name="acquireRetryAttempts" value="2"/>
    </bean>
    <!--3.sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--绑定Mybatis的配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>
    <!--4.配置dao接口扫描包，动态的实现Dao接口可以注入到Spring容器中-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--注入 sqlSessionFactory-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!--要扫描的dao包-->
        <property name="basePackage" value="com.qiu.dao"/>
    </bean>
</beans>

3、Spring整合service层（配置文件：spring-service.xml ）

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/aop
        https://www.springframework.org/schema/aop/spring-aop.xsd">

    <!--1.自动扫描service 下的包-->
    <context:component-scan base-package="com.qiu.service"/>

    <!--2.将我们的所有业务类，注入到Spring，可以通过配置，或者注解实现-->
    <bean id="bookServiceImpl" class="com.qiu.service.BookServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>

    <!--3.声明式事务配置-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--注入数据源-->
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!--4.aop事务支持-->
    <!--结合AOP实现事务的织入-->
    <!--配置事务通知：-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <!--给那些方法配置事务-->
        <!--配置事务的传播特性：new propagation= -->
        <tx:attributes>
            <!--一般只写 * 的即可-->
            <tx:method name="*" propagation="REQUIRED"/>
        </tx:attributes>
    </tx:advice>
    <!--配置事务切入-->
    <aop:config>
        <!--切入点根据自己需要修改-->
        <aop:pointcut id="txPointCut" expression="execution(* com.qiu.service.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
    </aop:config>
</beans>

Spring层搞定！

SpringMVC层编写

1、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
    <!--DispatcherServlet-->
    <servlet>
        <servlet-name>SpringMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>SpringMVC</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--乱码过滤-->
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>utf-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!--Session-->
    <session-config>
        <!--15分钟过期-->
        <session-timeout>15</session-timeout>
    </session-config>
</web-app>

2、spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd">

    <!--1.注解驱动-->
    <mvc:annotation-driven/>
    <!--2.静态资源过滤-->
    <mvc:default-servlet-handler/>
    <!--3.扫描包：controller-->
    <context:component-scan base-package="com.qiu.controller"/>
    <!--4.视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

3、Spring配置整合文件，applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">

    <import resource="classpath:spring-dao.xml"/>
    <import resource="classpath:spring-service.xml"/>
    <import resource="classpath:spring-mvc.xml"/>
</beans>

配置文件，暂时结束！

Controller 和 视图层

1、BookController 类编写 ，方法一：查询全部书籍

import com.qiu.pojo.Books;
import com.qiu.service.BookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.List;

@Controller
@RequestMapping("/book")
public class BookController {
    // controller 调用 service 层
    @Autowired
    @Qualifier("bookServiceImpl")
    private BookService bookService;

    //查询全部的书籍，并且返回到一个书籍展示页面
    @RequestMapping("/allBook")
    public String list(Model model){
        List<Books> books = bookService.queryAllBook();
        model.addAttribute("list",books);
        return "allBook";
    }
}

2、编写首页 index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>主页</title>
    <style>
      a{
        text-decoration: none;
        color:black;
        font-size: 18px;
      }
      h3{
        180px;
        height: 38px;
        margin: 100px auto;
        text-align: center;
        line-height: 38px;
        background: deepskyblue;
        border-radius:5px;
      }
    </style>
  </head>
  <body>
    <h3>
      <a href="${pageContext.request.contextPath}/book/allBook">进入书籍展示页面</a>
    </h3>
  </body>
</html>

3、书籍列表页面 allBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>书籍展示</title>
    <%--BootStrap 美化界面--%>
    <link href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
    <body>
        <div class="container">
            <div class="row clearfix">
                <div class="col-md-12 column">
                    <div class="page-header">
                        <h1>
                            <small>书籍列表 ———— 显示所有书籍</small>
                        </h1>
                    </div>
                </div>
                <div class="row">
                    <div class="col-md-8 column">
                        <%--查询书籍--%>
                        <form action="${pageContext.request.contextPath}/book/queryBook" method="post" style="float:right" class="form-inline">
                            <span style="color:red;font-weight: bolder">${error}</span>
                            <input type="text" name="queryBookName" class="form-control" placeholder="请输入要查询的书籍名称"/>
                            <input type="submit" value="查询" class="btn btn-primary"/>
                        </form>
                    </div>
                    <div class="col-md-4 column">
                        <%--toAddBook--%>
                        <a class="btn btn-primary" style="float:right" href="${pageContext.request.contextPath}/book/toAddBook" >新增书籍</a>
                    </div>
                </div>
            </div>

            <div class="row clearfix">
                <div class="col-md-12 column">
                    <table class="table table-hover table-striped">
                        <thead>
                            <tr>
                                <th>书籍编号</th>
                                <th>书籍名称</th>

                            </tr>
                        </thead>
                        <%--书籍从数据库中查询出来，从这个list中遍历出来：foreach--%>
                        <tbody>
                            <c:forEach var="book" items="${list}">
                                <tr>
                                    <td>${book.bookID}</td>
                                    <td>${book.bookName}</td>
                                    <td>${book.bookCounts}</td>
                                    <td>${book.detail}</td>
                                    <td>
                                        <a href="${pageContext.request.contextPath}/book/toUpdateBook/${book.bookID}">修改</a>
                                        &nbsp; | &nbsp;
                                        <a href="${pageContext.request.contextPath}/book/deleteBook/${book.bookID}">删除</a>
                                    </td>
                                </tr>
                            </c:forEach>
                        </tbody>
                    </table>
                </div>
            </div>
        </div>
    </body>
</html>

4、BookController 类编写 ， 方法二：添加书籍

//跳转到增加书籍页面
@RequestMapping("/toAddBook")
public String toAddPaper(){
    return "addBook";
}

//添加书籍的请求
@RequestMapping("/addBook")
public String addBook(Books books){
    System.out.println("addBook=>" + books);
    bookService.addBook(books);
    return "redirect:/book/allBook";    //重定向到我们的allBook
}

5、添加书籍页面：addBook.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>新增图书</title>
    <%--BootStrap 美化界面--%>
    <link href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container">
    <div class="row clearfix">
        <div class="col-md-12 column">
            <div class="page-header">
                <h1>
                    <small>新增书籍</small>
                </h1>
            </div>
        </div>
    </div>
    <form action="${pageContext.request.contextPath}/book/addBook" method="post">
        <div class="form-group">
            <label>书籍名称：</label>
            <input type="text" name="bookName" class="form-control" required>
        </div>
        <div class="form-group">
            <label>书籍数量：</label>
            <input type="text" name="bookCounts" class="form-control" required>
        </div>
        <div class="form-group">
            <label>书籍描述：</label>
            <input type="text" name="detail" class="form-control" required>
        </div>
        <div class="form-group">
            <input type="submit" class="form-control" value="添加">
        </div>
    </form>
</div>
</body>
</html>

6、BookController 类编写 ， 方法三：修改书籍

//跳转到修改书籍页面
@RequestMapping("/toUpdateBook/{bookId}")
public String toUpdatePaper(@PathVariable ("bookId") int id,Model model){
    Books book = bookService.queryBookById(id);
    model.addAttribute("QBook",book);
    return "updateBook";
}

//修改书籍的请求
@RequestMapping("/updateBook")
public String updateBook(Books books){
    System.out.println("updateBook=>" + books);
    bookService.updateBook(books);
    return "redirect:/book/allBook";
}

7、修改书籍页面 updateBook.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>修改图书</title>
    <%--BootStrap 美化界面--%>
    <link href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container">
    <div class="row clearfix">
        <div class="col-md-12 column">
            <div class="page-header">
                <h1>
                    <small>修改书籍</small>
                </h1>
            </div>
        </div>
    </div>
    <form action="${pageContext.request.contextPath}/book/updateBook" method="post">
        <input type="hidden" name="bookID" value="${QBook.bookID}">
        <div class="form-group">
            <label>书籍名称：</label>
            <input type="text" name="bookName" class="form-control" value="${QBook.bookName}" required>
        </div>
        <div class="form-group">
            <label>书籍数量：</label>
            <input type="text" name="bookCounts" class="form-control" value="${QBook.bookCounts}"  required>
        </div>
        <div class="form-group">
            <label>书籍描述：</label>
            <input type="text" name="detail" class="form-control" value="${QBook.detail}" required>
        </div>
        <div class="form-group">
            <input type="submit" class="form-control" value="修改">
        </div>
    </form>
</div>
</body>
</html>

8、BookController 类编写 ， 方法四：删除书籍

//删除书籍
@RequestMapping("/deleteBook/{bookId}")
public String deleteBook(@PathVariable ("bookId") int id){
    bookService.deleteBook(id);
    return "redirect:/book/allBook";
}

9、BookController 类编写 ， 方法五：根据书名模糊查询书籍

//查询书籍
@RequestMapping("/queryBook")
public String queryBook(String queryBookName,Model model){
    List<Books> books = bookService.queryBookByName(queryBookName);
    if(books.size()==0){
        books=bookService.queryAllBook();
        model.addAttribute("error","未查到");
    }
    model.addAttribute("list",books);
    return "allBook";
}

配置Tomcat，进行运行！

到目前为止，这个SSM项目整合已经完全的OK了，可以直接运行进行测试！
