Spring MVC注解配置简单示例

web.xml

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	version="2.5">
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring/applicationContext.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<servlet>
		<servlet-name>springmvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/classes/spring/*-servlet.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>springmvc</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
</web-app>

applicationContext.xml暂时不需要添加什么

springmvc-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>

	</bean>	
        
</beans>

	@RequestMapping(value="/testMethod", method = RequestMethod.GET)

}

测试连接:

<a href="<%=basePath %>test/start.do">test/start.do</a><br/>
<a href="<%=basePath %>test/testParam/str/1/2011-06-15.do">test/testParam/str/1/2011-06-15.do</a><br/>
<a href="<%=basePath %>test/testMethod.do">test/testMethod.do</a><br/>
