记录搭建ssm项目

搞java也快3年了，搭建一个ssm居然有点吃力。

参考链接：https://blog.csdn.net/gebitan505/article/details/44455235/

环境准备：jdk8、maven、idea

1、新建maven项目，增加web模块

2、集成spring

导入基本jar包：

 <properties>
        <java-version>1.8</java-version>
        <spring-verion>4.3.5.RELEASE</spring-verion>
        <mybatis-version>3.4.3</mybatis-version>
    </properties>

    <dependencies>

        <!-- spring -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>${spring-verion}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>${spring-verion}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>${spring-verion}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.batch</groupId>
            <artifactId>spring-batch-infrastructure</artifactId>
            <version>3.0.7.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>${spring-verion}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aop</artifactId>
            <version>${spring-verion}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>${spring-verion}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring-verion}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>${spring-verion}</version>
        </dependency>

        <!-- aop dependencies-->
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjweaver</artifactId>
            <version>1.8.9</version>
        </dependency>
        <!-- bean validate -->
        <dependency>
            <groupId>javax.validation</groupId>
            <artifactId>validation-api</artifactId>
            <version>1.1.0.Final</version>
        </dependency>

2、集成mybatis

spring的话什么也不写的话就只需要书写一下ApplicationContext.xml即可。所以直接准备与mybatis集成

导入jar：

<!-- mybatis -->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>${mybatis-version}</version>
        </dependency>
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
            <version>1.3.1</version>
        </dependency>
        <!-- mysql -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.11</version>
        </dependency>

然后写好简单的目录结构：

书写spring-mybatis的配置文件：

包含功能：spring的基本扫描，datascource的管理，sessionFactory的配置，transManage的配置，mybatis-mapper的扫描

<?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 http://www.springframework.org/schema/context/spring-context.xsd">

    <!-- spring和mybatis进行整合。主要进行扫描、注入、配置数据库 -->

    <context:property-placeholder location="classpath:config/props/jdbc.properties" ignore-unresolvable="true"/>

    <!-- 扫描 -->
    <context:component-scan base-package="com.testweb">
        <!-- 避免重复扫描controller -->
        <context:exclude-filter  type="annotation" expression="org.springframework.stereotype.Controller" />
    </context:component-scan>

    <!-- 配置数据源 -->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <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>

    <!-- session工厂 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <!-- 自动扫描mapping.xml文件 -->
        <property name="mapperLocations" value="classpath:com/testweb/dal/mapper/UserDOMapper.xml"></property>
    </bean>

    <!-- 扫描mapper接口 -->
    <!-- 使用tk.mybatis所以注释掉mybatis的
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <property name="basePackage" value="com.testweb.dal.mapper"/>
            <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        </bean>
    -->
    <bean class="tk.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.testweb.dal.mapper"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </bean>

    <!-- 事务管理 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

</beans>

tk.mybatis是通用mapper，为了简化xml编写的一个第三方插件

 <!-- tk.mybatis -->
        <dependency>
            <groupId>tk.mybatis</groupId>
            <artifactId>mapper</artifactId>
            <version>4.0.2</version>
        </dependency>

然后准备测试一下与spring与mybatis的整合是否成功

使用mybatis-generator进行实体的生成等。

依赖：

<!-- mybatis-generator -->
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.5</version>
        </dependency>
  <!-- junit -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
            <scope>test</scope>
        </dependency>

测试用到junit所以干脆把junit也带过来。

测试使用junit与spring集成，需要spring-test包：

<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>${spring-verion}</version>
        </dependency>

mybatis-generator.xml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
    <!--数据库驱动-->
    <classPathEntry    location="D:idea
epositorymysqlmysql-connector-java8.0.11mysql-connector-java-8.0.11.jar"/>
    <context id="DB2Tables"    targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--数据库链接地址账号密码-->
        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/testweb?useSSL=false" userId="root" password="961012gz">
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!--生成Model类存放位置-->
        <javaModelGenerator targetPackage="com.testweb.dal.model" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!--生成映射文件存放位置-->
        <sqlMapGenerator targetPackage="com.testweb.dal.mapper" targetProject="src/main/resources">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!--生成Dao类存放位置-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.testweb.dal.mapper" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
        <!--生成对应表及类名-->
        <table tableName="t_user" domainObjectName="UserDO" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
    </context>
</generatorConfiguration>

mybatis-generator为了idea运行配置插件：

            <!-- mybatis逆向工程 -->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <!--配置文件的位置-->
                    <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
            </plugin>

测试类：

package build;

import com.testweb.common.enums.UserLockStatusEnum;
import com.testweb.dal.mapper.UserDOMapper;
import com.testweb.dal.model.UserDO;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * @author zhen
 * @Date 2018/5/23 13:36
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:config/spring/spring-mybatis.xml"})
public class TestMyBatis {

    @Autowired
    private UserDOMapper userDOMapper;

    @Test
    public void testAddUser(){
        UserDO userDO = new UserDO();
        userDO.setName("admin");
        userDO.setPassword("123456");
        userDO.setPhone("18307006930");
        userDO.setStatus(UserLockStatusEnum.NORMAL.getCode());
        int i = userDOMapper.insert(userDO);
        System.out.println(i);
    }
}

然后进行spring与mvc的耦合：

写spring-mvc的配置文件：

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

    <mvc:annotation-driven></mvc:annotation-driven>
    <!-- 扫描Controller -->
    <context:component-scan base-package="com.testweb.controller"></context:component-scan>

    <!-- 使用mvc:annotation-driven替代，它有默认配置
    注解处理器适配器
    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"></bean>
    注解处理器映射器
    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"></bean>
    JSON转换器，支持@RequestBody与@ResponseBody
    <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8</value>
            </list>
        </property>
    </bean>
    -->

    <!-- 视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 前缀 -->
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <!-- 后缀 -->
        <property name="suffix" value=".jsp"/>
    </bean>

    <!-- 文件上传 -->
    <bean id="multipartResolver"
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 上传文件大小上限，单位为字节（10MB） -->
        <property name="maxUploadSize">
            <value>10485760</value>
        </property>
        <!-- 请求的编码格式，必须和jSP的pageEncoding属性一致，以便正确读取表单的内容，默认为ISO-8859-1 -->
        <property name="defaultEncoding">
            <value>UTF-8</value>
        </property>
    </bean>




</beans>

对了，配置log4j

配置文件：

log4j.rootLogger=INFO,Console,File  
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n  

#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender  
#指定输出目录
log4j.appender.File.File = E:/logs/testweb/testweb.log  
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB  
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL  
log4j.appender.File.layout = org.apache.log4j.PatternLayout  
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH:mm:ss}][%c]%m%n  

因为log4j的位置放在的不是默认的路径下，所以需要在web.xml中配置监听：

 <!-- log4j 配置文件的位置-->
    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:config/props/log4j.properties</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>

web.xml配置spring和springMVC：

<!-- 添加Spring监听 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:config/spring/spring-mybatis.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- Spring&mvc -->
    <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:config/spring/spring-mvc.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>springMvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!-- 编码过滤器 -->
    <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>
    

简单书写代码进行测试：

这里跑项目配合本地tomcat打包有点问题，直接使用jetty插件跑的：

   <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>

            <!-- jetty 插件 -->
            <plugin>
                <groupId>org.eclipse.jetty</groupId>
                <artifactId>jetty-maven-plugin</artifactId>
                <version>9.3.0.M1</version>
            </plugin>
