spring-mvc配置（结合注解）

spring-mvc.xml配置：

<?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: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.xsd
        				http://www.springframework.org/schema/mvc
        				http://www.springframework.org/schema/mvc/spring-mvc.xsd">

	<!-- 开启spring容器的自动扫描功能 -->
	<context:component-scan base-package="com.ge.springmvcanno"></context:component-scan>
	<!-- 开启springmvc的注解支持 -->
	<mvc:annotation-driven enable-matrix-variables="true"/>

	<!-- 指定静态资源文件的位置 -->
	<mvc:resources location="/static/" mapping="/static/**"></mvc:resources>



	<!-- 不再需要配置处理映射器，因为框架会自动使用 org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping 
		去根据我们定义的@RequestMapping该注解，完成"请求路径"到"处理该请求方法"之间的映射关系 -->

	<!-- 不再需要配置处理适配器，因为框架会自动使用 org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter 
		去根据我们定义的@RequestMapping该注解，完成"Servlet数据"到"Controller数据"之间的数据适配 -->

	
	<!-- 配置视图解析器 -->
	<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
		<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property>
		<!-- 前缀 -->
		<property name="prefix" value="/"></property>
		<!-- 后缀 -->
		<property name="suffix" value=".jsp"></property>
	</bean>
</beans>

web.xml配置：

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  
  <!-- 配置前端控制器:
  	1、接收用户的请求，并完成请求的派发
  	2、实例容器，并且完成配置文件转交给spring容器 -->
  	<servlet>
  		<servlet-name>mvc</servlet-name>
  		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  		<init-param>
  			<param-name>contextConfigLocation</param-name>
  			<param-value>classpath:spring-mvc.xml</param-value>
  		</init-param>
  	</servlet>
  	<servlet-mapping>
  		<servlet-name>mvc</servlet-name>
  		<url-pattern>/</url-pattern>
  	</servlet-mapping>
  
  
</web-app>

 

结合注解的表现层：（只需要加入@RequestMapping()注解就可以了）

@RequestMapping在类上表示定义命名空间，@RequestMapping在方法上表示具体的位置，请求就可以以“/sys/login”这样子访问到了

@RequestMapping("/sys")
@Controller
public class LoginController {

	private Logger log = Logger.getLogger(this.getClass());

	@RequestMapping(value = "/login")
	public ModelAndView login(HttpServletRequest req, HttpServletResponse res) {
		String loginName = req.getParameter("loginName");
		String password = req.getParameter("password");

		log.info(loginName);
		log.info(password);

		ModelAndView mv = new ModelAndView("/layout/main");
		return mv;

	}
	
	@RequestMapping(value = "/login02")
	public ModelAndView login02(HttpServletRequest req,HttpServletResponse res) {
		String loginName = req.getParameter("loginName");
		String password = req.getParameter("password");

		log.info(loginName);
		log.info(password);

		ModelAndView mv = new ModelAndView("/layout/main");
		return mv;

	}
}
