SpringMVC——checkboxes标签——集合元素为bean对象

SpringMVC配置文件参考：SpringMVC——form和input标签的使用：https://www.cnblogs.com/it-mh/articles/10570340.html

/FormTest/src/org/fkit/domain/Dept.java

package org.fkit.domain;

public class Dept {
    private Integer id;
    private String name;
    public Dept() {
        super();
    }
    public Dept(Integer id, String name) {
        super();
        this.setId(id);
        this.setName(name);
    }
    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;
    }
}

/FormTest/src/org/fkit/domain/Employee.java

package org.fkit.domain;

import java.util.List;

public class Employee {
    private List<Dept> depts;

    public List<Dept> getDepts() {
        return depts;
    }

    public void setDepts(List<Dept> depts) {
        this.depts = depts;
    }
    
}

/FormTest/src/org/fkit/controller/UserController.java

package org.fkit.controller;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.fkit.domain.Dept;
import org.fkit.domain.Employee;
import org.fkit.domain.User;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class UserController {
    @RequestMapping(value="/checkboxesform2",method=RequestMethod.GET)
    public String registerForm5(Model model) {
        Employee employee = new Employee();
        Dept dept = new Dept(1,"开发部");
        //为depts添加dept对象，页面checkbox复选框该项会被选中
        List<Dept> list = new ArrayList<Dept>();
        list.add(dept);
        employee.setDepts(list);
        //页面展示选项
        List<Dept> deptList = new ArrayList<Dept>();
        deptList.add(dept);
        deptList.add(new Dept(2,"销售部"));
        deptList.add(new Dept(3,"财务部"));
        //为model添加属性
        model.addAttribute("employee", employee);
        model.addAttribute("deptList", deptList);
        return "content/checkboxesForm2.jsp";
    }
}

/FormTest/WebContent/content/checkboxesForm2.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
    <form:form modelAttribute="employee" method="post" action="checkboxes">
        <table>
            <tr>
                <td>选择部门:</td>
                <td>
                    <form:checkboxes items="${deptList}" path="depts"
                        itemLabel="name" itemValue="id"/>
                </td>
            </tr>
        </table>
    </form:form>
</body>
</html>
