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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
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="/toAdd.do" class="com.zk.UserController.ToAddController"></bean>
<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"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </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="cache-control" 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">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</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
