1.效果截图

2.数据结构

[{"mcode":"UI","mname":"页面开发模板","micon":"glyphicon glyphicon-th","murl":"","explains":"开发页面的常用组件和页面","parent":null,"sort":4,
    "children":[
        {"mcode":"Cssd","mname":"CSS动画","micon":"glyphicon glyphicon-briefcase","murl":"/css/aaa","explains":"aaaaa啊啊啊aaaaa","parent":"UI","sort":1,
            "children":[]}]}]

//控制器         
@ResponseBody
@RequestMapping(value = "/selectZtreeModule", produces = {"application/json;charset=UTF-8"})
public List<Module> selectZtreeModule(HttpServletRequest request){
    List<Module> modules = new ArrayList<Module>();
    try {
        HashMap param = new HashMap();
        //。。。前台搜索关键字searchText。。。
        modules= moduleService.selectModuleList(param);
        modules=putChildren(modules);
    } catch (Exception e) {
        modules=null;
    }
    return modules;
}
//循环遍历下级节点，添加到module实体中
public List<Module> putChildren(List<Module> moduleList){
    if(moduleList.size()>0){
        for(Module mod2:moduleList){
            HashMap param = new HashMap();
            param.put("parent",mod2.getMcode());
            List<Module> res2 = moduleService.selectModuleList(param);
            if(res2.size()>0){res2=putChildren(res2);}
            mod2.setChildren(res2);
        }
    }
    return moduleList;
}

//实体
public class Module {
    private String mcode;
    private String mname;
    private String micon;
    private String murl;
    private String explains;
    private String parent;
    private Integer sort;
    private List<Module> children;
}

//mapper
 SELECT mcode,mname,micon,murl,explains,parent,sort FROM sys_module
    <where>
      <if test="searchText!=null">
        (mcode like #{searchText} or mname like #{searchText})
      </if>
      <if test="parent==null">
        AND parent is null
      </if>
      <if test="parent!=null">
        AND parent=#{parent}
      </if>
    </where>
      ORDER BY sort

3，关键js代码

<script type="text/javascript">
/*
        通过指定的方法来自定义栏数据
    */
    function customCheckBox(row, col){
        return "<input type='checkbox' name='city_name' onclick='selCk(this)'  id='"+row.mcode+"'>";
    }
    //图标
    function customerIcon(row){
        return "<span class='"+row.micon+"' aria-hidden='true'></span>";
    }
    //行点击事件
    function itemClickEvent(id, index, data){
        console.log("选中行：",data);
    }
    //表格设置
    var config = {
            id: "moduleListTable",   //表格ID
            width: "800",    //最小宽度
            renderTo: "div1",  //指定表格生成的父容器ID
            headerAlign: "left",
            headerHeight: "30",

            folderColumnIndex: "1",
            itemClick: "itemClickEvent",      //点击事件
            columns:[
                //headerAlign表头水平位置，dataAlign数据水平位置
                {headerText: "", headerAlign: "center", dataAlign: "center", width: "20", handler: "customCheckBox"},
                {headerText: "资源名称", dataField: "mname", headerAlign: "center", dataAlign: "left"},
                {headerText: "资源ID", dataField: "mcode", headerAlign: "center", width: "150"},

                {headerText: "资源图标", dataField: "micon", headerAlign: "center", dataAlign: "center", width: "100",handler:"customerIcon"},
                {headerText: "描述", dataField: "explains", headerAlign: "center", dataAlign: "left", width: "300"},
                {headerText: "父节点", dataField: "parent", headerAlign: "center", dataAlign: "center", width: "50",hidden:true},
                {headerText: "排序", dataField: "sort", headerAlign: "center", dataAlign: "center", width: "50"}
            ],
            url:"/module/selectZtreeModule"     //请求地址
        };
        //创建一个组件对象
        var treeGrid = new TreeGrid(config);
        treeGrid.show();   //相当于datagrid的reload，在添加删除数据之后调用刷新表格

    /*
        展开、关闭所有节点。
        isOpen=Y表示展开，isOpen=N表示关闭
    */
    function showAll(){
        if($("#Openbtn>i").hasClass("glyphicon-folder-close")){
            treeGrid.expandAll("Y");
            $("#Openbtn>i").removeClass("glyphicon-folder-close").addClass("glyphicon-folder-open");
        }else{
            treeGrid.expandAll("N");
            $("#Openbtn>i").removeClass("glyphicon-folder-open").addClass("glyphicon-folder-close");
        }

    }

    //级联选中、取消选中
    //(取消)选中父节点，其子节点自动(取消)选中
    function selCk(ck)
    {
        var ckId = $(ck).attr("id");
        var tr = $(ck).parent().parent();

        treeGrid.checkSubs(tr.attr("id"),$(ck).prop("checked"));
    }
</script>
