首先是web.xml
view plain <？xml version="1.0" encoding="UTF-8"？> <web-app version="3.0" 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_3_0.xsd"> <！――设置spring在本应用程序中的配置加载监听器 ――> <！――监听器会在应用程序启动时自动实例化 ――> <！――ContextLoaderListener实例化后自动寻找WEB-INF下的applicationContext.xml配置文件 ――> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
<！――解决spring乱码问题 ――> <filter> <filter-name>encoding</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>encoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
<！――全局Servlet调度配置 ――> <servlet> <！――若设置 servlet-name为[name] ――> <！――则DispatcherServlet在实例化后会自动加载[name]-servlet.xml ――> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <！――随服务器一同启动 ――> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping>
<！――错误页转向配置 ――> <error-page> <error-code>404</error-code> <location>/error.html</location> </error-page>
<！――首页文件名设置 ――> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.jsp</welcome-file> </welcome-file-list>
<！――设置持久化单元引用 ――> <！――此配置仅当Servlet容器支持Servlet 2.5时有效 ――> <persistence-unit-ref> <persistence-unit-ref-name>jdbc/spring</persistence-unit-ref-name> <persistence-unit-name>spring</persistence-unit-name> </persistence-unit-ref> </web-app>
其次是spring-servlet.xml
view plain <？xml version="1.0" encoding="UTF-8"？> <beans xmlns="http://www.springframework.org/schema/beans" xmlns：xsi=<a href="http://www.w3.org/2001/XMLSchema-instancehttp://www.w3.org/2001/XMLSchema-instance">http://www.w3.org/2001/XMLSchema-instance</a> 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-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"> <！――针对控制器返回视图字符串的修饰 最终视图路径为 [prefix][returnValue][suffix] ――> <！――例如prefix="/WEB-INF/" returnValue="admin/login" suffix=".jsp" ――> <！――最终的URL为 /WEB-INF/admin/login.jsp ――> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/pages/" /> <property name="suffix" value=".jsp" /> </bean>
<！――此处配置将 controller包和util包及其子包内部 ――> <！――包含注解 @Service @Component @Controller @Repository的类全部自动注入 ――> <context：component-scan base-package="controller，util" />
<！――为spring设置注解映射路径支持 @RequestMapping ――> <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" /> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
<！――设置spring拦截器 ――> <mvc：interceptors> <！――若mvc：mapping的path相同则按照配置先后形成拦截器链 ――> <mvc：interceptor> <mvc：mapping path="/*" /> <bean class="test.interceptor.TestInterceptor1" /> </mvc：interceptor> <mvc：interceptor> <mvc：mapping path="/*" /> <bean class="test.interceptor.TestInterceptor2" /> </mvc：interceptor> </mvc：interceptors> </beans>
最后是applicationContext.xml
view plain <？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：aop="http://www.springframework.org/schema/aop" xmlns：jee="http://www.springframework.org/schema/jee" xmlns：tx="http://www.springframework.org/schema/tx" xsi：schemaLocation="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/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
<context：component-scan base-package="test" /> <！――与持久化相关的配置 ――> <！――设置从应用服务器的JNDI树种查找哪一个具体的JDBC资源 ――> <！――jndi-name用于指示JDBC资源的jndi名称 ――> <jee：jndi-lookup id="entityManagerFactory" jndi-name="jdbc/spring" /> <！――开启从应用服务器的JNDI树中自动获取事务性DataSource ――> <tx：jta-transaction-manager /> <！――激活@Transactional注解驱动的事务行为 ――> <！――此处设置的transaction-manager为transactionManager ――> <tx：annotation-driven transaction-manager="transactionManager" /> </beans>
