Spring MVC自带的表单标签比较简单，很多时候需要借助EL和JSTL来完成。

下面是一个比较简单的表单提交页面功能：

1、User model

package com.my.controller.bean;import java.util.Date;import java.util.List;import javax.validation.constraints.Future;import javax.validation.constraints.Max;import javax.validation.constraints.Min;import javax.validation.constraints.NotNull;import org.hibernate.validator.constraints.Email;import org.hibernate.validator.constraints.Length;import org.hibernate.validator.constraints.NotEmpty;public class User { private long id; @Length(min=2, max=50, message="User name length range = 2-50") private String name; @Future(message="时间不能小于今天") private Date createTime; @NotEmpty(message="Customer不能为空") private List<Customer> customers; @NotNull(message="Girl不能为空") private boolean girl; private String[] cbx; @NotNull(message="Age can NOT be Null") @Min(value=18, message="最小18岁") @Max(value=100, message="最大100岁") private int age; @Email(message="Email格式不正确") private String email; public long getId() { return id; } public void setId(long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Date getCreateTime() { return createTime; } public void setCreateTime(Date createTime) { this.createTime = createTime; } public List<Customer> getCustomers() { return customers; } public void setCustomers(List<Customer> customers) { this.customers = customers; } public boolean isGirl() { return girl; } public void setGirl(boolean girl) { this.girl = girl; } public String[] getCbx() { return cbx; } public void setCbx(String[] cbx) { this.cbx = cbx; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; }}

2、Controller

package com.my.controller;import java.util.ArrayList;import java.util.Date;import java.util.List;import javax.validation.Valid;import org.springframework.stereotype.Controller;import org.springframework.validation.BindingResult;import org.springframework.validation.FieldError;import org.springframework.web.bind.annotation.ModelAttribute;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.servlet.ModelAndView;import com.my.controller.bean.Customer;import com.my.controller.bean.User;@Controller@RequestMapping(value="/post")public class TestPostController { private static List<User> users = new ArrayList<User>(); { //----------------------------------------------- // 设置Entity // ----------------------------------------------- users.add(new User()); User user = users.get(0); user.setId(1); user.setName("Robin"); user.setCreateTime(new Date()); user.setGirl(true); user.setCbx(new String[] {"1", "2", "3"}); user.setAge(18); user.setEmail("abcd@abc.com"); user.setCustomers(new ArrayList<Customer>()); Customer customer1 = new Customer(); customer1.setId(1); customer1.setCompany("Company - 1"); customer1.setCreateTime(new Date()); customer1.setUser(user); user.getCustomers().add(customer1); Customer customer2 = new Customer(); customer2.setId(1); customer2.setCompany("Company - 2"); customer2.setCreateTime(new Date()); customer2.setUser(user); user.getCustomers().add(customer2); } @RequestMapping public ModelAndView index() { ModelAndView view = new ModelAndView("TestPost/index"); view.addObject("users", users); return view; } @RequestMapping(value="/addUser", method=RequestMethod.POST) public ModelAndView addUser(@ModelAttribute @Valid User user, BindingResult result) { ModelAndView view = new ModelAndView("redirect:/post"); if(result.hasErrors()) { List<FieldError> errors = result.getFieldErrors(); for(FieldError err : errors) { System.out.println("ObjectName:" + err.getObjectName() + "\tFieldName:" + err.getField() + "\tFieldValue:" + err.getRejectedValue() + "\tMessage:" + err.getDefaultMessage()); } view.addObject("users", users); return view; } user.setId(users.size() + 1); user.getCustomers().get(0).setId(1); user.getCustomers().get(0).setUser(user); users.add(user); view.addObject("users", users); return view; } }

3、View

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><%@ page import="com.my.controller.bean.*" %><%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%><%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %><%@ taglib prefix="st" uri="http://pany" /><br/> <input type="submit" value="add" /> <sf:errors path="*"></sf:errors> </form> <hr/></body></html>
