jsp或html

<table id="userList" lay-filter="userList"></table>

js

//用户列表var tableIns = table.render({ elem: '#userList', url : 'userAction_findAll.action', cellMinWidth : 95, page : true, height : "full-125", limits : [10,15,20,25], limit : 10, id : "userListTable", cols : [[ {type: "checkbox", fixed:"left", width:50}, {field: 'userName', title: '用户名', minWidth:100, align:"center"}, {field: 'userEmail', title: '用户邮箱', minWidth:200, align:'center',templet:function(d){ return '<a class="layui-blue" href="mailto:'+d.userEmail+'" rel="external nofollow" >'+d.userEmail+'</a>'; }}, {field: 'userSex', title: '用户性别', align:'center'}, {field: 'userStatus', title: '用户状态', align:'center',templet:function(d){ return d.userStatus == '0' ? "正常使用":"<span class='layui-red'>限制使用</span>"; }}, {field: 'userGrade', title: '用户等级', align:'center'}, {field: 'userEndTime', title: '最后登录时间', align:'center',minWidth:150}, {title: '操作', minWidth:175, templet:'#userListBar',fixed:"right",align:"center"} ]]});

UserAction.java

// 接收前端发送来的分页参数private int page = 1;public void setPage(int page) { this.page = page;}public int getPage() { return page;}private int limit = 2;public int getLimit() { return limit;}public void setLimit(int limit) { this.limit = limit;}public String findAll(){ List<User> allUser = this.getUserService().findAllUser(this.getPage(), this.getLimit()); Map<String, Object> result = new HashMap<String, Object>(); result.put("code", 0); result.put("msg", ""); result.put("count", this.getUserService().findTotalRecord(key)); JSONArray array = JSONArray.fromObject(allUser); result.put("data", array); // 将其转换为JSON数据，并压入值栈返回 ActionContext.getContext().getValueStack().set("jsonData", JSONObject.fromObject(result)); return "success";}

struts.xml配置

<!-- 用户配置 --><package name="user" namespace="/" extends="common,json-default"> <action name="userAction_*" class="userAction" method="{1}"> <result name="success" type="json"> <param name="root">jsonData</param> </result> </action></package>

返回JSON数据格式，也是layui数据表格要求的格式

{ "code": 0, "msg": "", "count": 15, "data": [ { "usersId": "1", "userName": "user12", "userEmail": "123@qq.com", "userSex": "女", "userStatus": "0", "userGrade": "倔强青铜", "userEndTime": "2018-11-11 15:22:33" },{ "usersId": "2", "userName": "asd", "userEmail": "123@qq.com", "userSex": "男", "userStatus": "1", "userGrade": "秩序白银", "userEndTime": "2018-11-11 15:22:33" }, ...... ]}

注意：

1.js中table的field需要与返回的数据key相对应，比如field: “userName”与“userName”: “asd”

2.layui的数据表格向url发送请求时，会附上page以及limit这两个参数，所以服务端需要接收并以此为条件查找数据

前端展示效果
