ssm整合

准备工作

1. 添加依赖

 <dependencies>
     <!--Junit-->
     <dependency>
         <groupId>junit</groupId>
         <artifactId>junit</artifactId>
         <version>4.12</version>
     </dependency>
     <!--数据库驱动-->

     </dependency>
     <!-- 数据库连接池 -->
     <dependency>
         <groupId>com.mchange</groupId>
         <artifactId>c3p0</artifactId>
         <version>0.9.5.2</version>
     </dependency>
 ​
     <!--Servlet - JSP -->
     <dependency>

         <artifactId>jstl</artifactId>
         <version>1.2</version>
     </dependency>
 ​
     <!--Mybatis-->
     <dependency>
         <groupId>org.mybatis</groupId>
         <artifactId>mybatis</artifactId>
         <version>3.5.2</version>
     </dependency>
     <dependency>
         <groupId>org.mybatis</groupId>
         <artifactId>mybatis-spring</artifactId>
         <version>2.0.2</version>
     </dependency>
 ​
     <!--Spring-->
     <dependency>

         <artifactId>spring-jdbc</artifactId>
         <version>5.1.9.RELEASE</version>
     </dependency>
 </dependencies>

2. maven资源过滤(pom.xml)

 <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>

3.完整目录

pojo/service/comtroller/dao

4. 新建 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>

5.新建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>

2.mybatis层

1.新建database.properties 数据库配置文件

 jdbc.driver=com.mysql.jdbc.Driver
 # useSSL属性为是否使用ssl安全链接,可能导致无法访问数据库
 jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
 jdbc.username=root
 jdbc.password=123

2.更改mybatis核心配置文件 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>
     
     <!--别名,为了使用model类时方便,不需要写全名-->
     <typeAliases>
         <package name="com.mvc.pojo"/>
     </typeAliases>
     
     <!--绑定mapper映射文件-->
     <mappers>
         <mapper resource="mappers/userMapper.xml"/>
     </mappers>
 ​
 </configuration>

3.实体类编写

4.dao层编写,mapper接口

5.编写对应的mapper.xml配置文件

 <?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>
 <select id="selectAllUser" resultType="User">
        SELECT * from user
     </select>
 </mapper>

6.编写service层以及实现借口(service层调用dao层)

Spring层

         <session-timeout>15</session-timeout>
     </session-config>

 

2.编写spring-mvc.xml配置文件, Spring整合MVC层

 <?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/mvc
     https://www.springframework.org/schema/mvc/spring-mvc.xsd">
 ​
     <!-- 配置SpringMVC -->
     <!-- 1.开启SpringMVC注解驱动 -->
     <mvc:annotation-driven />
     <!-- 2.静态资源默认servlet配置-->
     <mvc:default-servlet-handler/>
 ​
     <!-- 3.配置jsp 显示ViewResolver视图解析器 -->
     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
         <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
         <property name="prefix" value="/WEB-INF/jsp/" />
         <property name="suffix" value=".jsp" />
     </bean>
 ​
     <!-- 4.扫描web相关的bean -->
     <context:component-scan base-package="com.mvc.controller" />
 ​
 </beans>

3.配置整合文件applicaitonContext.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="spring-dao.xml"/>
     <import resource="spring-service.xml"/>
     <import resource="spring-mvc.xml"/>
     
 </beans>

  <tx:advice id="txAdvice" transaction-manager="transactionManager">
         <tx:attributes>
             <tx:method name="add" propagation="REQUIRED"/>
             <tx:method name="delete" propagation="REQUIRED"/>
             <tx:method name="update" propagation="REQUIRED"/>
             <tx:method name="query" read-only="true"/>
             <tx:method name="*" propagation="REQUIRED"/>
         </tx:attributes>
     </tx:advice>
 ​
     <aop:config>
         <aop:pointcut id="txPointCut" expression="execution(* com.tedu.dao.*.*())"/>
         <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
     </aop:config>
