筹建基于全注解的Spring+Spring MVC+MyBatis框架

以实例讲解Spring+Spring MVC+MyBatis框架的搭建步骤：

?

一、配置web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  <!-- 配置log4j日志   --> <context-param>  <param-name>log4jConfigLocation</param-name>  <param-value>/WEB-INF/classes/log4j.properties</param-value> </context-param> <listener>  <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener>  <!-- 字符集过滤器 --> <filter>  <filter-name>characterEncodingFilter</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>characterEncodingFilter</filter-name>  <url-pattern>/*</url-pattern> </filter-mapping>  <!-- Spring view分发器(中心控制器) --> <servlet>  <servlet-name>dispatcher</servlet-name>  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  <!-- 初始化参数   -->  <init-param>   <param-name>contextConfigLocation</param-name>   <param-value>/WEB-INF/classes/spring/*.xml</param-value>  </init-param>  <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping>  <servlet-name>dispatcher</servlet-name>  <!-- 表示拦截所有/XX的请求  -->  <url-pattern>/</url-pattern> </servlet-mapping>  <!-- 激活静态资源的默认配置,解决Rest风格兼容 --> <servlet-mapping>  <servlet-name>default</servlet-name>  <url-pattern>*.css</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name>  <url-pattern>*.js</url-pattern> </servlet-mapping> <servlet-mapping>  <servlet-name>default</servlet-name>  <url-pattern>*.gif</url-pattern> </servlet-mapping> <servlet-mapping>  <servlet-name>default</servlet-name>  <url-pattern>*.jpg</url-pattern> </servlet-mapping>  <welcome-file-list>  <!--<welcome-file>/index.jsp</welcome-file>-->  <welcome-file></welcome-file> </welcome-file-list> </web-app>

二、配置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"       xmlns:p="http://www.springframework.org/schema/p"       xmlns:tx="http://www.springframework.org/schema/tx"       xmlns:aop="http://www.springframework.org/schema/aop"       xmlns:context="http://www.springframework.org/schema/context"       xsi:schemaLocation="http://www.springframework.org/schema/beans       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd       http://www.springframework.org/schema/tx       http://www.springframework.org/schema/tx/spring-tx-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-2.5.xsd"       default-init-method="init">             <!-- 引入jdbc配置文件 -->    <context:property-placeholder location="classpath:jdbc.properties" />        <!--创建jdbc数据源 -->    <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}" />    </bean>     <!-- 创建SqlSessionFactory，同时指定数据源 -->    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource" />        <!-- 配置sql映射文件所在位置  注意：默认与mapper类位置相同   -->        <property name="mapperLocations" value="classpath:sqlmap/*.xml" />    </bean>  	<!-- 配置事务管理器，全注解声明式事务  -->    <!--    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name="dataSource" ref="dataSource" />    </bean>	-->		<!-- 配置事务管理器，使用tx标签配置的拦截器声明式事务  -->    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name="dataSource" ref="dataSource" />    </bean>    <!-- 配置事务的传播特性  -->    <tx:advice id="txAdvice" transaction-manager="transactionManager">        <tx:attributes>        	<!--         		REQUIRED：如果存在一个事务，则支持当前事务；如果没有事务，则开启一个新事务。        		NESTED:如果当前存在事务，则在嵌套事务内执行；如果当前没有事务，则开启一个新事务。			-->            <tx:method name="add*" propagation="NESTED" />            <tx:method name="del*" propagation="NESTED" />            <tx:method name="*" read-only="true" />        </tx:attributes>    </tx:advice>    <!-- 配置事务的切入点  -->    <aop:config>        <aop:pointcut id="targetMethod" expression="execution(* com.xieke.test.service.impl.*.*(..))" />        <aop:advisor advice-ref="txAdvice" pointcut-ref="targetMethod" />    </aop:config>     <!-- Mapper接口所在包名，Spring会自动查找其下的Mapper -->    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="com.xieke.test.mapper" />    </bean></beans>

三、配置dispatcher-servlet.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"        xmlns:aop="http://www.springframework.org/schema/aop"        xmlns:context="http://www.springframework.org/schema/context"       xmlns:mvc="http://www.springframework.org/schema/mvc"        xmlns:tx="http://www.springframework.org/schema/tx"        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://www.springframework.org/schema/aop         http://www.springframework.org/schema/aop/spring-aop-3.0.xsd         http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd         http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-3.0.xsd         http://www.springframework.org/schema/mvc         http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd         http://www.springframework.org/schema/tx         http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">                <!-- 自动扫描注解组件并且自动注入 -->   		<context:component-scan base-package="com.xieke.test" />                <!--视图解析器-->	    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">	        <property name="prefix" value="/WEB-INF/jsp/" />	        <property name="suffix" value=".jsp" />      	    </bean>	    	    <!-- 激活spring mvc的注解驱动  -->	    <mvc:annotation-driven/>	    <!-- 配置spring mvc的默认首页  -->	    <mvc:view-controller path="/" view-name="redirect:/car/index" /></beans>
