首先,我们先写一个入门小案例,先熟悉一下springmvc是什么,了解一下springmvc的运行流程,对加强springmvc的深层理解有很大帮助
.第一步,创建一个maven项目:
<?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"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="MyWebApp" version="2.5">
<display-name>SpringMVC</display-name> <!-- SpringMVC的入口 -->
<servlet>
<servlet-name>SpringMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
<!--
默认加载配置文件：
/WEB-INF/{servlet-name}-servlet.xml
-->
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<!--
可选配置：
*.do、*.action
/
/xxx/* 不可以：
/*
-->
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list> </web-app>
<?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.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 定义handlerMapping -->
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean> <!-- 定义适配器 -->
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/> <!-- 定义视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/views/"/>
<!-- 后缀 -->
<property name="suffix" value=".jsp"/>
</bean>
<!-- 定义Handler对象 -->
<bean name="/hello.do" class="com.j1.springmvc.controller.HelloController"/> </beans>
package com.j1.springmvc.controller; import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller; public class HelloController implements Controller{ @Override
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModelAndView mv =new ModelAndView();
mv.setViewName("hellos");
mv.addObject("msg","恭喜你,小逼崽子,第一个SpringMvc程序成功了");
return mv;
} }
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>${msg}</h1>
</body>
</html>
在浏览器输入:http://localhost:8080/myspring-demo/hello.do
效果如图所示:
至此一个入门记得springmvc就写好了.
使用注解
package com.j1.springmvc.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView; @RequestMapping("/hello2")
@Controller
public class Hello2Controller { @RequestMapping("/show")
public ModelAndView show(){
ModelAndView mv = new ModelAndView();
mv.setViewName("hello");
mv.addObject("msg", "呀呀呀,恭喜你,小逼崽子,我的第一个注解Controller测试成功！");
return mv;
} }
SpringMVC-servlet.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"

-->
<context:component-scan base-package="com.j1.springmvc.controller"/>
<!-- 定义文件上传解析器 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 设定默认编码 -->
<property name="defaultEncoding" value="UTF-8"></property>
<!-- 设定文件上传的最大值5MB，5*1024*1024 -->
<property name="maxUploadSize" value="5242880"></property>
</bean> </beans>
