学习Spring MVC,关于注解的Spring MVC,关于控制器的Spring MVC,学习Spring,简单Spring MVC实例

实现步骤 在Eclipse中新建项目Web项目TestSpring。 引入Spring和Spring MVC相关Jar包。 在WebRoot的WEB-INF文件下新建spring-servlet.xml：

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="www.springframework/schema/beans" xmlns:xsi="www.w3/2001/XMLSchema-instance" xmlns:mvc="www.springframework/schema/mvc" xmlns:context="www.springframework/schema/context" xsi:schemaLocation=" www.springframework/schema/mvc www.springframework/schema/mvc/spring-mvc-3.0.xsd www.springframework/schema/beans www.springframework/schema/beans/spring-beans-3.0.xsd www.springframework/schema/context www.springframework/schema/context/spring-context-3.0.xsd"> <!-- 基于注解 --> <context:component-scan base-package="spring"></context:component-scan> <mvc:annotation-driven /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> </bean> <!-- 基于控制器 --> <!-- <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" /> <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter" /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> </bean> <bean name="/hello" class="spring.HelloWorldController" /> --> </beans>

在WebRoot的WEB-INF文件下配置web.xml：

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="www.w3/2001/XMLSchema-instance" xmlns="java.sun/xml/ns/javaee" xsi:schemaLocation="java.sun/xml/ns/javaee java.sun/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>TestSpring</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <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> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <servlet> <servlet-name>dispatch</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatch</servlet-name> <url-pattern>/</url-pattern> <!-- 不带尾椎 --> <!-- <url-pattern>*.do</url-pattern> --> <!-- 带尾椎 --> </servlet-mapping> </web-app> 新建Spring包，并新建类HomeController，用于做控制器（注解使用重点）： package spring; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.servlet.ModelAndView; @Controller public class HomeController { //@RequestMapping 中请求Action为"home"，支持方法有post,get， (required = false)参数非必要 @RequestMapping(value = "home", method = { RequestMethod.POST, RequestMethod.GET }) public String responsePage(@RequestParam(required = false) String page) { return page; } //支持HTTP协议所有方法，@ResoinseBody = 响应此“方法”返回值为页面内容。参数键为"para"，默认para默认值为"this is body" @ResponseBody @RequestMapping(value = "getshow") public String responseBody(@RequestParam(value = "para", defaultValue = "this is body", required = false) String content) { return content; } //显示El表达式，响应body.jsp视图 @RequestMapping(value = "getel") public ModelAndView responseEL(){ ModelAndView mv = new ModelAndView(); mv.addObject("message", "你们好！我是通过EL表达式出来的内容"); mv.setViewName("body"); return mv; } } 在WEB-INF下新建文件夹jsp，在jsp文件夹下添加home.jsp，和body.jsp： <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "www.w3/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> hello ,this is a spring mvc annotation demo! </body> </html> <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "www.w3/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> this is body page; <p>${message}</p> </body> </html> 最后，运行服务器，在地址栏输入地址： localhost:8080/TestSpring/home localhost:8080/TestSpring/getshow?para=my%20is%20Jaiky localhost:8080/TestSpring/getel 效果图： 获取源代码：Java SpringMVC 注解学习 源代码说明：由于本人使用MyEclipse在源代码中导入了Hibernate Jar包，使用时如遇报错请自行删除不需要的配置，或另行导入到新项目。 声明
