一、layui数据表格相关组件官网介绍
userManager.jsp：
<%@ page language="java" contentType="text/html; charset=UTF-8"

<%@ include file="/common/header.jsp" %>
Insert title here
userManager.js：
let layer,$,table;

//初始化数据表格

//绑定查询按钮的点击事件
$('#btn_search').click(function(){
query();
});
//绑定新增按钮的点击事件
$('#btn_add').click(function(){
row=null;
open('新增');
});
});
//1.初始化数据表格
function initTable(){
table.render({ //执行渲染
elem: '#tb', //指定原始表格元素选择器（推荐id选择器）
// url: 'user.action?methodName=list', //请求地址
height: 500, //自定义高度
loading: false, //是否显示加载条（默认 true）
cols: [[ //设置表头
{field: 'id', title: '用户编号', width: 120},
{field: 'name', title: '用户名', width: 120},
{field: 'loginName', title: '登录账号', width: 140},
{field: '', title: '操作', width: 300,toolbar:'#toolbar'},
]]
});
//在页面中的
中必须配置lay-filter="tb_goods"属性才能触发属性!!!

//2.点击查询

//3.对话框

二、用户管理后台代码
UserDao:
package com.zking.dao;
import java.util.List;
import java.util.Map;
import com.zking.entity.User;
import com.zking.util.BaseDao;
import com.zking.util.PageBean;
import com.zking.util.StringUtils;
public class UserDao extends BaseDao{
public User login(User user) throws Exception {
String sql="select * from t_oa_user where loginName = '"+user.getLoginName()+"' and pwd = '"+user.getPwd()+"' ";
//查询符合条件的用户
List users = super.executeQuery(sql, User.class, null);
return users == null || users.size() ==0 ? null : users.get(0);
}
//查询用户信息对应的角色，角色是通过case when得来的
public List> list(User user,PageBean pageBean) throws Exception{
String sql="select * rn" +
",(case rid rn" +
"when 1 then '管理员' rn" +
"when 2 then '发起者' rn" +
"when 3 then '审批者' rn" +
"when 4 then '参与者' rn" +
"when 5 then '会议室管理员' rn" +
"else '其他' end rn" +
") roleName rn" +
"from t_oa_user "+
"where 1=1 ";
String name = user.getName();
if(StringUtils.isNotBlank(name)) {
sql += " and name like '%"+name+"%' ";
}
// 当实体类的属性完全包含数据库查询出来的列段的时候使用
// super.executeQuery(sql, User.class, pageBean)
// 返回 List>，对应的是链表查询，单个实体类对象不完全包含查询的烈列段
return super.executeQuery(sql, pageBean);
}
public int add(User user) throws Exception{
String sql="insert into t_oa_user(name,loginName,pwd) values(?,?,?)";
return super.executeUpdate(sql, user, new String[] {"name","loginName","pwd"});
