搭建基于全注解的Spring+Spring MVC+MyBatis框架

西湖鱼

　　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>
<tx:annotation-driven transaction-manager="transactionManager" />
-->
<!-- 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" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
<!-- 默认情况下会自动注入id=sqlSessionFactory的bean，也可以按上述方式指定sqlSessionFactory -->
</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>
　　至此搭建完成，以上配置都是主要配置，详细搭建过程请下载源码：http://pan.baidu.com/s/1bn4pkwn
