使用layui实现树形结构的方法

 @RequestMapping(value = "/lists")
public void getList( HttpServletResponse response) {
List list = this.companyService.getList();
String[] exclude={"Groups"};
JsonUtils.printJsonStringFromArrayObjectWithExclude(response, list, exclude);

}

 public List getList(){
ChangeDataSource.changeDataSource(DataSource.dataSource2);
String hql=" from Company";
return this.baseDao.exeQueryHql(hql);
}

<table id="treeMenu" class="layui-table" style="margin-top: 2px;">
<div style="clear:both;"></div>
