若依前后端分离版本项目总结笔记

若依前后端分离学习笔试

1.路由问题

注意这个是前端找到你的路由的路径

2.表格开关按钮快速实现

html 复制代码
  <el-table-column label="状态" align="center" key="status">
        <template slot-scope="scope">
          <el-switch
            v-model="scope.row.status"
            active-value="0"
            inactive-value="1"
            @change="handleStatusChange(scope.row)"
          ></el-switch>
        </template>
      </el-table-column>




//methods add this method


    // 状态修改
    handleStatusChange(row) {  
      let text = row.status === "0" ? "启用" : "停用";
      this.$modal.confirm('确认要"' + text + '""' + row.title + '"量表吗?').then(function() {
        return changeStatus(row.scaleId,row.status);
      }).then(() => {
        this.$modal.msgSuccess(text + "成功");
      }).catch(function() {
        row.status = row.status === "0" ? "1" : "0";
      });
    },
// import this
import { listScaleInfo, getScaleInfo, delScaleInfo, addScaleInfo, updateScaleInfo, changeStatus } from "@/api/businessManagement/scaleBaseinfo";






// 修改分类状态
export function changeStatus(scaleId,status) {
    const data = {
      scaleId,
      status
    }
    return request({
      url: '/businessManage/scaleInfo/changeStatus',
      method: 'put',
      data: data
    })
  }
  



    @Log(title = "修改状态", businessType = BusinessType.UPDATE)
    @PutMapping("/changeStatus")
    public  AjaxResult  changeStatus(@RequestBody ScaleBaseinfo scaleBaseinfo)
    {

        return toAjax(scaleBaseinfoService.changeStatus(scaleBaseinfo));
    }

//interface generate this method automatically


  @Override
    public int changeStatus(ScaleBaseinfo scaleBaseinfo) {
        return scaleBaseinfoMapper.updateScaleBaseinfo(scaleBaseinfo);
    }

3.选中指定的导出和批量导出

html 复制代码
      <el-col :span="1.5">
        <template>
          <div>
            <el-button type="primary" icon="el-icon-download" @click="handleExport"  size="mini">批量导出
              <el-dropdown @command="handleExportCommand">
              <span class="el-dropdown-link">
                <i class="el-icon-arrow-down el-icon--right"></i>
              </span>
              <el-dropdown-menu slot="dropdown">
                <el-dropdown-item command="selected">当前选中</el-dropdown-item>
                <el-dropdown-item command="search">当前搜索</el-dropdown-item>

            </el-dropdown></el-button>
            
          </div>
        </template>
        
      </el-col>




 /** 导出按钮操作 */
    handleExport() {
      // 根据不同的导出选项执行不同的导出逻辑
      if (this.exportOption === 'selected') {
        // 导出当前选中的数据
        // 执行导出逻辑
        if(this.queryParams.stuIds.length === 0){
          // alert("请选中学生数据进行导出!");
          this.$modal.msgWarning("请选中学生数据进行导出!");
          return;
        }

      this.download('usersManage/student/export', {
        ...this.queryParams 
       }, `Student_${new Date().getTime()}.xlsx`)
   
      } else if (this.exportOption === 'search') {
        // 导出当前搜索的数据
        // 执行导出逻辑
        this.download('usersManage/student/export', {
        ...this.queryParams  
       }, `Student_${new Date().getTime()}.xlsx`)
      } else {
        // 默认导出全部数据
        // 执行导出逻辑
        this.$modal.msgWarning("请选中导出的类型!");
      }
    },
    handleExportCommand(command) {
      this.exportOption = command;
      this.handleExport();
    },

后端code

java 复制代码
    /**
     * 导出学生基本信息列表
     */
    @PreAuthorize("@ss.hasPermi('usersManage:student:export')")
    @Log(title = "学生基本信息", businessType = BusinessType.EXPORT)
    @PostMapping("/export")
    public void export(HttpServletResponse response, BasicStudent basicStudent)
    {
        List<BasicStudent> list = bStudentService.selectStudentVoList(basicStudent);
        ExcelUtil<BasicStudent> util = new ExcelUtil<BasicStudent>(BasicStudent.class);
        util.exportExcel(response, list, "学生基本信息数据");
    }






//注意这里第一行实现的东西,直接可以batchExport

    <select id="selectBStudentList" parameterType="BasicStudent" resultMap="BStudentResult">
        <include refid="selectBStudentVo"/>
        <where>
            <if test="stuIds != null">
            AND stu_id IN
            <foreach collection="stuIds" item="stuId" separator="," open="(" close=")">
                #{stuId}
            </foreach>

            <if test="studentId != null  and studentId != ''"> and stu_id = #{studentId}</if>

            ]这个数据 怎么用elmentUI层级表示,一级显示的label是areaName, children: 'basicGradeList',二级显示的label是gradeName, children: 'basicClassList',三级显示的是className,没有children,怎么用elmentUI表示

5.路由跳转问题

外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-m54viF4f-1692860445256)(C:\\Users\\My Windows pc\\AppData\\Roaming\\Typora\\typora-user-images\\image-20230815164743889.png)

html 复制代码
  viewGrade(row){
      const areaId = row.areaId;
      this.$router.push({
            path: "/schoolManage/grade/",
            query: {
              areaId:  areaId
            }
          });
    },

代办问题:

查询的一些列表没有加上 学校id
