一、后端

1、实体类

//仓库实体类
        /** 产品仓库 */
        private Long warehouseId;
    
        /** 产品仓库编号 */
        private String warehouseNo;
    
        /** 产品仓库名称 */
        private String warehouseName;
    
        /** 库区 */
        private List<ProductStorageArea> children;
    
    //******************************************************************
    
    //库区实体类
        /** 产品库区 */
        private Long areaId;
    
        /** 产品库区编号 */
        private String areaNo;
    
        /** 产品库区名称 */
        private String areaName;
    
        /** 产品仓库ID */
        private Long productWarehouseId;
    
        /** 库位 */
        private List<ProductStorageLocation> children;
    
    //******************************************************************
    
    //库位实体类
        /** 产品库位ID */
        private Long locationId;
    
        /** 产品库位编号 */
        private String locationNo;
    
        /** 产品库位名称 */
        private String locationName;
    
        /** 产品库区ID */
        private Long productStorageAreaId;

2、controller层

/**
         * 查询产品仓库列表
         */
        @GetMapping("/TreeList")
        public AjaxResult TreeList(ProductWarehouse productWarehouse)
        {
            return AjaxResult.success(productWarehouseService.selectProductWarehouseListTree(productWarehouse));
        }

3、mapper层

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE mapper
    PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
    "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

        <select id="selectProductWarehouseListTree" resultMap="ProductWarehouseResult">
            select
                a.warehouse_id,
                a.warehouse_no,
                a.warehouse_name,
                a.enable_flag,
                b.product_warehouse_id,
                b.area_id,
                b.area_no,
                b.area_name,
                b.enable_flag,
                c.product_storage_area_id,
                c.location_id,
                c.location_no,
                c.location_name,
                c.enable_flag
            from wms_product_warehouse a
            left join wms_product_storage_area b
            on a.warehouse_id=b.product_warehouse_id
            left join wms_product_storage_location c
            on b.area_id=c.product_storage_area_id
        </select>

二、前端

1、XXX.js

// 查询产品仓库列表
    export function listWarehouseTree() {
      return request({
        url: '/wms/warehouse/TreeList',
        method: 'get'
      })
    }

2、XX.vue

2.1、form表单

<el-form-item label="仓库" prop="warehouseId">
                  <el-cascader :options="warehouseOptions" v-model="warehouseInfo" :props="warehouseProps" @change="handleWarehouseChanged"/>
         </el-form-item>

2.2、JavaScript

//刚才 1、XXX.js 的地址
    import { listWarehouseTree } from "@/api/XXX/XXXXX";

data() {
        return {
          //仓库
          warehouseInfo:[],
          warehouseOptions:[],
          warehouseProps:{
            multiple: false,
            value: 'pId',
            label: 'pName',
          },
          // 表单参数
          form: {},
        };
      },

created() {
        //仓库
        this.getListWarehouseTree();
      },

methods:{
    //仓库三级
        getListWarehouseTree(){
          listWarehouseTree().then( response =>{        
            this.warehouseOptions = response.data;
            this.warehouseOptions.map(w =>{
              w.children.map(l =>{
                //三级
                let lstr =JSON.stringify(l.children).replace(/areaId/g,'lId').replace(/locationId/g, 'pId').replace(/locationName/g,'pName');                  
                l.children = JSON.parse(lstr);
                
              }); 
              //二级
              let wstr = JSON.stringify(w.children).replace(/warehouseId/g,'wId').replace(/areaId/g, 'pId').replace(/areaName/g,'pName');  
              w.children =  JSON.parse(wstr); 
            });
            //一级
            let ostr=JSON.stringify(this.warehouseOptions).replace(/warehouseId/g,'pId').replace(/warehouseName/g, 'pName');
            this.warehouseOptions = JSON.parse(ostr);
          });
        },
        //仓库默认
        handleWarehouseChanged(obj){      
          if(obj !=null){
            this.form.warehouseId = obj[0];
            this.form.areaId = obj[1];
            this.form.locationId = obj[2];
          }
        },
    }

本篇文章是在ruoyi vue的框架下进行实现的
