springmvc参数传递（二）

1.项目结构

2.视图页面

①userInfor_add1.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>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
    <h1>添加用户信息3！！</h1>
    <form action="userInfor_add1.do" method="post">
        编号：<input type="text" name="userId"/><br>
        姓名：<input type="text" name="userName"/><br>
        性别：<input type="text" name="userSex"/><br>
        兴趣爱好：
            <input type="checkbox" name="userXq" value="LOL"/>LOL
            <input type="checkbox" name="userXq" value="英雄联盟"/>英雄联盟
            <input type="checkbox" name="userXq" value="DOTA"/>DOTA<br>
        <input type="submit" value="提交">
    </form>
</body>
</html>

②userInfor_add2.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>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
    <h1>添加用户信息3！！</h1>
    <form action="userInfor_add2.do" method="post">
        编号：<input type="text" name="userId"/><br>
        姓名：<input type="text" name="userName"/><br>
        性别：<input type="text" name="userSex"/><br>
        兴趣爱好：
            <input type="checkbox" name="userXq" value="LOL"/>LOL
            <input type="checkbox" name="userXq" value="英雄联盟"/>英雄联盟
            <input type="checkbox" name="userXq" value="DOTA"/>DOTA<br>
        时间：<input type="text" name="userTime"/><br>
        <input type="submit" value="提交">
    </form>
</body>
</html>

3.controller层代码

package com.spring;

import java.text.SimpleDateFormat;
import java.util.Date;
import org.springframework.beans.propertyeditors.CustomDateEditor;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.ServletRequestDataBinder;
import org.springframework.web.bind.annotation.InitBinder;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.spring.po.UserInfor;

@Controller
/*@RequestMapping("/user")*/
public class UserInforController {
    
    
    @RequestMapping(value="/userInfor_add1.do",method=RequestMethod.POST)
    public String add(UserInfor user){
        System.out.println(user);
        return "user/success";
    }
    
    @RequestMapping(value="/userInfor_add2.do",method=RequestMethod.POST)
    public String add1(UserInfor user){
        System.out.println(user);
        
        return "user/success";
    }
    /**
     * 时间属性编辑器
     * @param bin
     */
    @InitBinder
    public void initBinder(ServletRequestDataBinder bin){
        SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        CustomDateEditor cust=new CustomDateEditor(sdf, true);
        bin.registerCustomEditor(Date.class, cust);
    }
    
}

4.po层代码

package com.spring.po;

import java.util.Arrays;
import java.util.Date;

public class UserInfor {

    private Integer userId;
    private String userName;
    private String userSex;
    private String[] userXq;
    private Date userTime;
    
    public Date getUserTime() {
        return userTime;
    }
    public void setUserTime(Date userTime) {
        this.userTime = userTime;
    }
    public String[] getUserXq() {
        return userXq;
    }
    public void setUserXq(String[] userXq) {
        this.userXq = userXq;
    }
    public Integer getUserId() {
        return userId;
    }
    public void setUserId(Integer userId) {
        this.userId = userId;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
    public String getUserSex() {
        return userSex;
    }
    public void setUserSex(String userSex) {
        this.userSex = userSex;
    }
    @Override
    public String toString() {
        return "UserInfor [userId=" + userId + ", userName=" + userName + ", userSex=" + userSex + ", userXq="
                + Arrays.toString(userXq) + ", userTime=" + userTime + "]";
    }
    
}

5.控制台打印

注：重点是对象的传入，时间的传入，时间属性编辑器的配置，视图层与po层映射关系（复选框对应数组）
