今天使用AbstractCommandController做一个提交表单的样例
（1）首先，建立一个User.java
package com.zk.domain;
import java.util.Date;
public class User {
private Integer id;
private String name;
private String age;
private String birthday;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
public String getBirthday() {
return birthday;
}
public void setBirthday(String birthday) {
this.birthday = birthday;
}
}
（2）第二步，实现ToAddController.java，跳转至add.jsp,
package com.zk.UserController;
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 ToAddController implements Controller{
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
// TODO Auto-generated method stub
ModelAndView mv=new ModelAndView();
mv.setViewName("add");
return mv;
}
}
（3）第三步，实现CommandController.java
package com.zk.UserController;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractCommandController;
import com.zk.domain.User;
//从页面接受参数，封装javaBean的User对象
public class CommandController extends AbstractCommandController{
//指定把参数封装到那个对象。
public CommandController(){
this.setCommandClass(User.class);
}
@Override
protected ModelAndView handle(HttpServletRequest request,
HttpServletResponse response, Object command, BindException errors)
throws Exception {
// TODO Auto-generated method stub
//值被封装命令对象
User user=(User) command;
ModelAndView mv=new ModelAndView();
//设置models
mv.addObject("user",user);
//指定返回视图界面
mv.setViewName("index");
return mv;
}
}
（4）第四步，配置SpringMVC.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:aop="http://www.springframework.org/schema/aop"

http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">
<!-- 配置处理器映射器 -->
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>
<bean class="org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter"></bean>
<!-- 命令对象 -->
<bean id="/command.do" class="com.zk.UserController.CommandController"></bean>
<!-- 跳转到Add页面 -->

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
（5）两个jsp界面
add.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'add.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">

</head>
<body>
<form action="${pageContext.request.contextPath }/command.do">
Id：<input type="text" name="id" id="id"/><br>
name：<input type="text" name="name" id="name"/><br>
age：<input type="text" name="age" id="age"/><br>
birthday：<input type="text" name="birthday" id="birthday"/><br>
<input type="submit" value="提交" />
</form>
</body>
</html>
index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<meta http-equiv="pragma" content="no-cache">

<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">

-->
</head>
<body>
<!-- ${hello } -->
<h1>${user.name}||${user.id}||${user.age}||${user.birthday}</h1>
</body>
</html>
运行结果如下：
http://ms-20170731tkkc:8080/SpringMVC_004/command.do?id=1&name=zk&age=24&birthday=1995-03-04
带过来的参数
注解写法
Usercontroller.java
package com.zk.Controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller//<bean id="UserController" class="UserController路径">
public class UserController {
//访问路径注意更改
//请求映射value="/hello.do",
//@RequestMapping("hello")
//@RequestMapping("/hello.do")
//@RequestMapping(value="/hello.do")
//@RequestMapping(value="/hello.do",method=RequestMethod.GET)
@RequestMapping(value="/hello.do",method={RequestMethod.GET,RequestMethod.POST})
public String myHello(){
return "hello";
}
@RequestMapping("receive")
public String receiveInt(Integer id){
System.out.println(id);
return "success";
}
}
