Student.java：

package com.jsoft.testspring.testmvcform;public class Student {private Integer age;private String name;private Integer id;public void setAge(Integer age) {this.age = age;}public Integer getAge() {return age;}public void setName(String name) {this.name = name;}public String getName() {return name;}public void setId(Integer id) {this.id = id;}public Integer getId() {return id;}
}

StudentController.java：

package com.jsoft.testspring.testmvcform;import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;@Controller
public class StudentController {@RequestMapping(value="/student",method=RequestMethod.GET)public ModelAndView student(){return new ModelAndView("student","command",new Student());}@RequestMapping(value="/addStudent",method=RequestMethod.POST)public String addStudent(Student student,Model model){model.addAttribute("name",student.getName());model.addAttribute("age",student.getAge());model.addAttribute("id", student.getId());return "result";}
}

说明：在这里，第一个service方法student()，我们已经在名称为“command”的ModelAndView对象中传递一个空的Student对象，因为如果你在JSP文件中使用<form:form>标签时，spring框架需要一个名称的“command”的对象。所以，当student()方法被调用时，它返回student.jsp视图。第二个service方法addStudent()将调用/addStudent URL中的POST方法。将根据提交的信息准备好模型对象。最后一个“result”视图会从service方法中返回，它将导致呈现result.jsp。

student.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">
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<html>
<head><title>Spring MVC Form Handling</title>
</head>
<body><h2>Student Information</h2>
<form:form method="POST" action="addStudent"><table><tr><td><form:label path="name">Name</form:label></td><td><form:input path="name" /></td></tr><tr><td><form:label path="age">Age</form:label></td><td><form:input path="age" /></td></tr><tr><td><form:label path="id">id</form:label></td><td><form:input path="id" /></td></tr><tr><td colspan="2"><input type="submit" value="Submit"/></td></tr>
</table>
</form:form>
</body>
</html>

result.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><title>Spring MVC Form Handling</title>
</head>
<body><h2>Submitted Student Information</h2><table><tr><td>Name</td><td>${name}</td></tr><tr><td>Age</td><td>${age}</td></tr><tr><td>ID</td><td>${id}</td></tr>
</table>
</body>
</html>
