dtree展示时使用@RestController注解的方式

package com.cc.controller;
import com.cc.common.DataGridView;
import com.cc.common.DeptNode;
import com.cc.common.PageBean;
import com.cc.domain.Dept;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;
import java.util.List;

@RestController
@RequestMapping("dept")
public class DeptController {

    @Autowired
    private DeptService deptService;

    //展示树形结构
    @RequestMapping("buildLeftTree")
    public DataGridView buildLeftTree(){

      List<Dept>deptList=deptService.queryDeptList();

      List<DeptNode>treeNodeList = new ArrayList<>();
        for (Dept dept : deptList) {
            treeNodeList.add(new DeptNode(dept.getId(),dept.getPid(),dept.getTitle()));
        }
        return new DataGridView(treeNodeList);
    }
   }

定义一个类

package com.cc.common;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class DataGridView {
    private Integer  code =0;
    private String  msg ="";
    private Long  count=0L;
    private Object  data;

    public DataGridView(Long count,Object data){
        super();
        this.count=count;
        this.data=data;
    }

    public DataGridView(Object data){
        super();
        this.data=data;
    }

}
