spring整合springmvc

一、项目结构

二、导包

源码中有这些包

三、spring-mvc.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:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd          http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd          http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd          http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd"><!-- 配置自动扫描包 --><context:component-scan base-package="com.ssh" /><mvc:annotation-driven /><!-- 配置视图解析器 --><beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/pages/"></property><property name="suffix" value=".jsp"></property></bean></beans>  

四、applicationContext.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:context="http://www.springframework.org/schema/context"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd          http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd          http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd"><!-- 配置自动扫描的包 --><context:component-scan base-package="com.ssh"><!-- 扫描时跳过 @Controller 注解的JAVA类（控制器） --><context:exclude-filter type="annotation"expression="org.springframework.stereotype.Controller" /></context:component-scan></beans>  

五、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"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"id="WebApp_ID" version="3.0"><display-name>ssh</display-name><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list><!-- 配置spring ioc容器 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:config/applicationContext.xml</param-value></context-param><!-- Bootstraps the root web application context before servlet initialization --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 配置springmvc 的DispatcherServlet --><servlet><servlet-name>dispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:config/spring-mvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><!-- Map all requests to the DispatcherServlet for handling --><servlet-mapping><servlet-name>dispatcherServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping><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></web-app>

六、UserController

package com.ssh.controller;import javax.servlet.http.HttpServletRequest;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import com.ssh.service.UserService;@Controller@RequestMapping("/user")public class UserController {@Autowiredprivate UserService userService;@RequestMapping(value = "save")public String save(HttpServletRequest request) {String username = request.getParameter("username");String password = request.getParameter("password");System.out.println(username + " " + password);System.out.println("controller save...");userService.save();return "success";}}

七、UserService

package com.ssh.service;public interface UserService {void save();}

八、UserServiceImpl

package com.ssh.service;import org.springframework.stereotype.Service;@Servicepublic class UserServiceImpl implements UserService {@Overridepublic void save() {System.out.println("userservice save...");}}

九、add.jsp

<%@ 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>添加用户</h1><form action="user/save" method="post">用户 <input type="text" name="username" /><br /> 密码 <input type="text"name="password" /><br /> <input type="submit" value="添加"></form></body></html></html>

十、success.jsp

<%@ 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>success</body></html>
