一个很简单的Spring MVC 入门实例

首先要引入相关的包

1、model

package com.tan.model;

public class User {

	private int id;
	private String name;
	private String sex;
	private String email;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {
		this.sex = sex;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	
}

2、controller

package com.tan.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.tan.model.User;

@Controller
@RequestMapping("/user.do")
public class IndexController {
	
	@RequestMapping(params = "method=save")
	public ModelAndView save(User user) {
		return new ModelAndView("success", "user", user);
	}

}

3、applicationContext.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	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-3.0.xsd   
   http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd   
   http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
	<context:annotation-config />
	<context:component-scan base-package="com.tan" />  <!-- 自动扫描所有注解该路径 -->
<!-- 	<bean -->
<!-- 		class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" /> -->
<!-- 	<bean -->
<!-- 		class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /> -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix">
			<value>/</value>
		</property>
		<property name="suffix">
			<value>.jsp</value>
		</property>
	</bean>
</beans>

4、web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
	<display-name></display-name>
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
	<!-- 核心控制器 -->
	<servlet>
		<servlet-name>SpringMVC_Test1</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/applicationContext.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<servlet-mapping>
		<servlet-name>SpringMVC_Test1</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

</web-app>

5、view：index.jsp用于提交表单，success.jsp
