Spring+Mybatis+SpringMVC+Maven+MySql搭建实例

一、准备工作

1. 首先创建一个表：

CREATE TABLE `t_user` (
  `USER_ID` int(11) NOT NULL AUTO_INCREMENT,
  `USER_NAME` char(30) NOT NULL,
  `USER_PASSWORD` char(10) NOT NULL,
  `USER_EMAIL` char(30) NOT NULL,
  PRIMARY KEY (`USER_ID`),
  KEY `IDX_NAME` (`USER_NAME`)
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8

随便插入一些数据：

INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (1, '林炳文', '1234567@', 'ling20081005@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (2, 'evan', '123', 'fff@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (3, 'kaka', 'cadg', 'fwsfg@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (4, 'simle', 'cscs', 'fsaf@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (5, 'arthur', 'csas', 'fsaff@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (6, '小德', 'yuh78', 'fdfas@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (7, '小小', 'cvff', 'fsaf@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (8, '林林之家', 'gvv', 'lin@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (9, '林炳文Evankaka', 'dfsc', 'ling2008@126.com');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (10, 'apple', 'uih6', 'ff@qq.com');

二、工程创建

1、Maven工程创建

（1）新建

（2）选择快速框架

（3）输出项目名，包，记得选war(表示web项目，以后可以spingMVC连起来用)

（4）创建好之后 

目录如下：

（5）检查下

这三个地方JDK的版本一定要一样！！！！

三、sping+mybatis配置

1、整个工程目录如下：

2、POM文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </dependency>
    </dependencies>

</project>

3、java代码-------src/main/java

目录如下：

（1）User.Java

对应数据库中表的字段，放在src/main/java下的包com.lin.domain

package com.lin.domain;

/**
 * User映射类
 *
 * @author linbingwen
 * @time 2015.5.15
 */
public class User {
    private Integer userId;
    private String userName;
    private String userPassword;
    private String userEmail;

    public Integer getUserId() {
        return userId;
    }

    public void setUserId(Integer userId) {
        this.userId = userId;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getUserPassword() {
        return userPassword;
    }

    public void setUserPassword(String userPassword) {
        this.userPassword = userPassword;
    }

    public String getUserEmail() {
        return userEmail;
    }

    public void setUserEmail(String userEmail) {
        this.userEmail = userEmail;
    }

    @Override
    public String toString() {
        return "User [userId=" + userId + ", userName=" + userName
                + ", userPassword=" + userPassword + ", userEmail=" + userEmail
                + "]";
    }

}

（2）UserDao.java

Dao接口类，用来对应mapper文件。放在src/main/java下的包com.lin.dao,内容如下：

package com.lin.dao;


import com.lin.domain.User;

/**
 * 功能概要：User的DAO类
 *
 * @author linbingwen
 * @since 2015年9月28日
 */
public interface UserDao {
    /**
     *
     * @author linbingwen
     * @since 2015年9月28日
     * @param userId
     * @return
     */
    public User selectUserById(Integer userId);

}

（2）UserService.java和UserServiceImpl.java

service接口类和实现类，放在src/main/java下的包com.lin.service,内容如下：

UserService.java

package com.lin.service;

import org.springframework.stereotype.Service;

import com.lin.domain.User;

/**
 * 功能概要：UserService接口类
 *
 * @author linbingwen
 * @since  2015年9月28日
 */
public interface UserService {
    User selectUserById(Integer userId);

}

UserServiceImpl.java

package com.lin.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.lin.dao.UserDao;
import com.lin.domain.User;

/**
 * 功能概要：UserService实现类
 *
 * @author linbingwen
 * @since  2015年9月28日
 */
@Service
public class UserServiceImpl implements UserService{
    @Autowired
    private UserDao userDao;

    public User selectUserById(Integer userId) {
        return userDao.selectUserById(userId);

    }

}

（4）mapper文件

用来和dao文件对应，放在src/main/java下的com.lin.mapper包下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.lin.dao.UserDao">
<!--设置domain类和数据库中表的字段一一对应，注意数据库字段和domain类中的字段名称不致，此处一定要！-->
    <resultMap id="BaseResultMap" type="com.lin.domain.User">
        <id column="USER_ID" property="userId" jdbcType="INTEGER" />
        <result column="USER_NAME" property="userName" jdbcType="CHAR" />
        <result column="USER_PASSWORD" property="userPassword" jdbcType="CHAR" />
        <result column="USER_EMAIL" property="userEmail" jdbcType="CHAR" />
    </resultMap>
    <!-- 查询单条记录 -->
    <select id="selectUserById" parameterType="int" resultMap="BaseResultMap">
        SELECT * FROM t_user WHERE USER_ID = #{userId}
    </select>
</mapper>

4、资源配置-------src/main/resources

目录如下：

(1)mybatis配置文件

这里没有什么内容，因为都被放到application.xml中去了,放在src/main/resources下的mybatis文件夹下

mybatis-config.xml内容如下：

<?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>

（2）数据源配置jdbc.properties

放在src/main/resources下的propertiesy文件夹下

jdbc_driverClassName=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/learning
jdbc_username=root
jdbc_password=christmas258@

（3）Spring配置

这是最重要的：application.xml内容如下

<?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:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="
           http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-3.0.xsd">

     <!-- 引入jdbc配置文件 -->
     <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
               <value>classpath:properties/*.properties</value>
                <!--要是有多个配置文件，只需在这里继续添加即可 -->
            </list>
        </property>
    </bean>



    <!-- 配置数据源 -->
    <bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <!-- 不使用properties来配置 -->
        <!-- <property name="driverClassName" value="com.mysql.jdbc.Driver" />
            <property name="url" value="jdbc:mysql://localhost:3306/learning" />
            <property name="username" value="root" />
            <property name="password" value="christmas258@" /> -->
       <!-- 使用properties来配置 -->
        <property name="driverClassName">
            <value>${jdbc_driverClassName}</value>
        </property>
        <property name="url">
            <value>${jdbc_url}</value>
        </property>
        <property name="username">
            <value>${jdbc_username}</value>
        </property>
        <property name="password">
            <value>${jdbc_password}</value>
        </property>
    </bean>

    <!-- 自动扫描了所有的XxxxMapper.xml对应的mapper接口文件，这样就不用一个一个手动配置Mpper的映射了，只要Mapper接口类和Mapper映射文件对应起来就可以了。 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage"
            value="com.lin.dao" />
    </bean>

    <!-- 配置Mybatis的文件 ，mapperLocations配置**Mapper.xml文件位置，configLocation配置mybatis-config文件位置-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="mapperLocations" value="classpath*:com/lin/mapper/**/*.xml"/>
        <property name="configLocation" value="classpath:mybatis/mybatis-config.xml" />
        <!-- <property name="typeAliasesPackage" value="com.tiantian.ckeditor.model"
            /> -->
    </bean>

    <!-- 自动扫描注解的bean -->
    <context:component-scan base-package="com.lin.service" />

</beans>

（4）日志打印log4j.properties

就放在src/main/resources

log4j.rootLogger=DEBUG,Console,Stdout

#Console
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n

log4j.logger.java.sql.ResultSet=INFO
log4j.logger.org.apache=INFO
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG

log4j.appender.Stdout = org.apache.log4j.DailyRollingFileAppender
log4j.appender.Stdout.File = E://logs/log.log
log4j.appender.Stdout.Append = true
log4j.appender.Stdout.Threshold = DEBUG
log4j.appender.Stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.Stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n

四、单元测试

上面的配置完好，接下来就是测验成功

整个目录 如下：

（1）测试基类

package com.lin.baseTest;

import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * 功能概要：
 *
 * @author linbingwen
 * @since  2015年9月28日
 */
//指定bean注入的配置文件
@ContextConfiguration(locations = { "classpath:application.xml" })
//使用标准的JUnit @RunWith注释来告诉JUnit使用Spring TestRunner
@RunWith(SpringJUnit4ClassRunner.class)
public abstract class SpringTestCase extends AbstractJUnit4SpringContextTests{
    protected Logger logger = LoggerFactory.getLogger(getClass());
}

（2）测试类

package com.lin.service;

import org.apache.log4j.Logger;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;

import com.lin.baseTest.SpringTestCase;
import com.lin.domain.User;

/**
 * 功能概要：UserService单元测试
 *
 * @author linbingwen
 * @since  2015年9月28日
 */
public class UserServiceTest extends SpringTestCase {
    @Autowired
    private UserService userService;
    Logger logger = Logger.getLogger(UserServiceTest.class);

    @Test
    public void selectUserByIdTest(){
        User user = userService.selectUserById(10);
        logger.debug("查找结果" + user);
    }


}

选中selectUserByIdTest，然后右键如下运行

输出结果：

重要打印的结果

这里

2015-09-28 15:20:15,129 [main] DEBUG [com.lin.dao.UserDao.selectUserById] - ==>  Preparing: SELECT * FROM t_user WHERE USER_ID = ?
2015-09-28 15:20:15,160 [main] DEBUG [com.lin.dao.UserDao.selectUserById] - ==> Parameters: 10(Integer)
2015-09-28 15:20:15,160 [main] DEBUG [org.mybatis.spring.SqlSessionUtils] - Closing non transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@6b64bff9]
2015-09-28 15:20:15,160 [main] DEBUG [org.springframework.jdbc.datasource.DataSourceUtils] - Returning JDBC Connection to DataSource
2015-09-28 15:20:15,160 [main] DEBUG [com.lin.service.UserServiceTest] - 查找结果User [userId=10, userName=apple, userPassword=uih6, userEmail=ff@qq.com]

数据库：

程序成功运行，并且结果正确！

 

到这里配置好spring+mybatis+mysql!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

=====================================================

这里开始添加spirngMVC，并转换maven工程为web项目

 

五、转换web工程

接上面的工程接着说，此时要加spingMVC之前，工程得再稍微转换下

此时webapp下的结果还没有显示出来，因为此时我们还没有配置此的项目为web项目

 

再次进去Properties配置，如下图所示：如果没有显示如下，那就先把dynamic web module的√给去掉，然后重新再打开 这个

进入，然后输入如下内容

确定OK之后,webapp下面就会自动生成一些文件，如下

 

 

 

 

 

六、配置SpringMVC

（1）修改POM文件，增加了一此内容，新的POM文件如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <!-- mybatis版本号 -->
        <mybatis.version>3.2.1</mybatis.version>
    </properties>

    <dependencies>

            <scope>provided</scope>
        </dependency>
    </dependencies>

</project>

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
</dependency>

<!-- javaee-web-api包 注意和项目使用的JDK版本对应 -->
<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-web-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
</dependency>

(2) 在src/main/resource中添加springmvc文件夹，然后添加文件spring-mvc.xml，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:p="http://www.springframework.org/schema/p"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:context="http://www.springframework.org/schema/context"
  xmlns:mvc="http://www.springframework.org/schema/mvc"
  xsi:schemaLocation="
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.2.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

    <!-- 扫描controller（controller层注入） -->
   <context:component-scan base-package="com.lin.controller"/>

   <!-- 对模型视图添加前后缀 -->
     <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
      p:prefix="/WEB-INF/view/" p:suffix=".jsp"/>
</beans>

（3）配置web,xml

目录如下 ：

这里是关键，web.xml是用来起动sping、spingMVC

放在src/main/webapp/WEB-INF下。内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
    <display-name>Archetype Created Web Application</display-name>
   <!-- 起始欢迎界面 -->
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

    <!-- 读取spring配置文件 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:application.xml</param-value>
    </context-param>
    <!-- 设计路径变量值 -->
    <context-param>
        <param-name>webAppRootKey</param-name>
        <param-value>springmvc.root</param-value>
    </context-param>


    <!-- Spring字符集过滤器 -->
    <filter>
        <filter-name>SpringEncodingFilter</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>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>SpringEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- 日志记录 -->
    <context-param>
        <!-- 日志配置文件路径 -->
        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:log4j.properties</param-value>
    </context-param>
    <context-param>
        <!-- 日志页面的刷新间隔 -->
        <param-name>log4jRefreshInterval</param-name>
        <param-value>6000</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- springMVC核心配置 -->
    <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <!--spingMVC的配置路径  -->
            <param-value>classpath:springmvc/spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!-- 拦截设置 -->
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!-- 错误跳转页面 -->
    <error-page>
        <!-- 路径不正确 -->
        <error-code>404</error-code>
        <location>/WEB-INF/errorpage/404.jsp</location>
    </error-page>
    <error-page>
        <!-- 没有访问权限，访问被禁止 -->
        <error-code>405</error-code>
        <location>/WEB-INF/errorpage/405.jsp</location>
    </error-page>
    <error-page>
        <!-- 内部错误 -->
        <error-code>500</error-code>
        <location>/WEB-INF/errorpage/500.jsp</location>
    </error-page>
</web-app>

（4）添加index.jsp

在src/main/webapp/WEB-INF下新建一个文件夹view,添加一个index.jsp，内容如下：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<html>
<body>
<h2>Hello World!</h2>
 ${user.userId}<br>
 ${user.userName}<br>
 ${user.userPassword}<br>
 ${user.userEmail}<br>
</body>
</html>

（5）最后就是controller的书写了

在src/main/java下新建一个包com.lin.controller.然后新建一个类UserController.java,其内容如下：

 

package com.lin.controller;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.lin.domain.User;
import com.lin.service.UserService;

/**
 * 功能概要：UserController
 *
 * @author linbingwen
 * @since  2015年9月28日
 */
@Controller
public class UserController {
    @Resource
    private UserService userService;

    @RequestMapping("/")
    public ModelAndView getIndex(){
        ModelAndView mav = new ModelAndView("index");
        User user = userService.selectUserById(1);
        mav.addObject("user", user);
        return mav;
    }
}

（6）最后的运行！
最后，就是成果了，已经全部都配置好了。我们可以开始以web工程运行了！

然后一路next

接下来控制台就会打印日志出来了！如下
