layui有自己的一套特定的数据格式交互，必须参数code:0,msg:"",count:数据size(int),data:"数据List"

<link rel="stylesheet" href="static/layui/css/layui.css" media="all" />
<script type="text/javascript" src="static/layui/layui.js"></script><table class="layui-hide" id="test" lay-filter="table"></table>

• js代码

layui.use(['form','layer','table'], function(){var table = layui.table,form = layui.form,$=layui.$;table.render({elem: '#test'  //绑定table id,url:'sys/menu/list'  //数据请求路径,cellMinWidth: 80,cols: [[{type:'numbers'},{field:'name', title:'菜单名称'},{field:'parentName', title:'父菜单名称',width:150},{field:'url', title: '菜单路径'},{field:'perms', title: '菜单权限'},{field:'type', title:'类型'},{field:'icon', title:'图标'},{field:'orderNum', title:'排序'},{fixed: 'right',title: '操作', width:180, align:'center', toolbar: '#toolBar'}//一个工具栏  具体请查看layui官网]],page: true   //开启分页,limit:10   //默认十条数据一页,limits:[10,20,30,50]  //数据分页条,id: 'testReload'  ,where:{} // 传参数});
});

• java后台

@RequestMapping("/list")
@ResponseBody
@RequiresPermissions("sys:menu:list")
public Layui list(@RequestParam Map<String, Object> params){//查询列表数据Query query = new Query(params);List<SysMenuEntity> menuList = sysMenuService.queryList(query);int total = sysMenuService.queryTotal(query);PageUtils pageUtil = new PageUtils(menuList, total, query.getLimit(), query.getPage());return Layui.data(pageUtil.getTotalCount(), pageUtil.getList());
}

• Layui工具类

public class Layui  extends HashMap<String, Object> {public static Layui data(Integer count,List<?> data){Layui r = new Layui();r.put("code", 0);r.put("msg", "");r.put("count", count);r.put("data", data);return r;}
}

• PageUtils

@Data
public class PageUtils implements Serializable {private static final long serialVersionUID = -1202716581589799959L;//总记录数private int totalCount;//每页记录数private int pageSize;//总页数private int totalPage;//当前页数private int currPage;//列表数据private List<?> list;/*** 分页* @param list        列表数据* @param totalCount  总记录数* @param pageSize    每页记录数* @param currPage    当前页数*/public PageUtils(List<?> list, int totalCount, int pageSize, int currPage) {this.list = list;this.totalCount = totalCount;this.pageSize = pageSize;this.currPage = currPage;this.totalPage = (int)Math.ceil((double)totalCount/pageSize);}
}
