SSM框架-----------SpringMVC+Spring+Mybatis框架整合教程

注明：此片博客为他处修改得来，不是原创
一、导入框架所需jar包
1 .mysql数据库驱动包以及数据库连接池相关包
2. mybatis框架包和mybatis+spring框架整合包
3. spring包
如图


二、配置相关的文件
school(为项目名字)
1.配置school-mybatis.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:mybatis="http://mybatis.org/schema/mybatis-spring"         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://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring.xsd         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">           <!-- 自动扫描 -->      <context:component-scan base-package="cn.wallance" />      <!-- 引入配置文件 -->      <bean id="propertyConfigurer"          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">          <property name="location" value="classpath:jdbc.properties" />      </bean>      <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"          destroy-method="close">          <property name="driverClassName" value="${driver}" />          <property name="url" value="${url}" />          <property name="username" value="${username}" />          <property name="password" value="${password}" />          <!-- 配置连接池的初始值 -->        <property name="initialSize" value="1" />        <!-- 连接池的最大值 -->        <!-- <property name="maxActive" value="500"/> -->        <!-- 最大空闲时，当经过一个高峰之后，连接池可以将一些用不到的连接释放，一直减少到maxIdle为止 -->        <!-- <property name="maxIdle" value="2"/> -->        <!-- 当最小空闲时，当连接少于minIdle时会自动去申请一些连接 -->        <property name="minIdle" value="1" />        <property name="maxActive" value="100" />        <property name="maxIdle" value="20" />        <property name="maxWait" value="1000" />     </bean>      <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->      <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:cn/wallance/mapping/*.xml"></property>      </bean>      <!-- DAO接口所在包名，Spring会自动查找其下的类 -->      <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">          <property name="basePackage" value="cn.wallance.dao" />          <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>      </bean>      <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->      <bean id="transactionManager"          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">          <property name="dataSource" ref="dataSource" />      </bean>      </beans>

jdbc.properties文件内容如下所示：

2.配置school-servlet.xml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-3.1.xsd        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">      <!-- 开启注解 -->      <mvc:annotation-driven/>      <!-- 设置组件扫描的基础包 -->      <context:component-scan base-package="cn.wallance.web"/>      <!-- 配置视图解析器 -->      <bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver">          <property name="prefix" value="/WEB-INF/school/" />          <property name="suffix" value=".jsp" />      </bean>     </beans>

3.配置web.xml,整合SSM框架

<?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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">  <!-- 配置DispatcherServlet -->  <servlet>     <servlet-name>school</servlet-name>     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  </servlet>  <servlet-mapping>     <servlet-name>school</servlet-name>     <url-pattern>/</url-pattern>  </servlet-mapping>  <!-- Spring 的监听器可以通过这个上下文参数来获取school-mybatis.xml的位置 -->  <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:school-mybatis.xml</param-value>     </context-param>    <!-- 创建Spring的监听器 -->  <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>  <!-- 创建字符过滤器 -->  <filter>     <filter-name>CharacterFilter</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>CharacterFilter</filter-name>      <url-pattern>/*</url-pattern>  </filter-mapping></web-app>
