springboot+vue2+elementui實(shí)現(xiàn)時(shí)間段查詢方法

更新時(shí)間：2024年05月24日 15:20:43 作者：m87里的光

這篇文章主要介紹了springboot+vue2+elementui實(shí)現(xiàn)時(shí)間段查詢方法,本文通過(guò)實(shí)例代碼給大家介紹的非常詳細(xì),感興趣的朋友跟隨小編一起看看吧

1.前端代碼

使用elementui的時(shí)間段選擇器：

<el-date-picker v-model="queryPage.itemTime" type="daterange"
 value-format="yyyy-MM-dd" class="filter-item"
range-separator="至"  start-placeholder="創(chuàng)建日期"  
end-placeholder="創(chuàng)建日期">
        </el-date-picker>

設(shè)置查詢字段，為數(shù)組形式：

  queryPage: {
        page: 1,
        limit: 20,
        itemTime:[],
      },

編寫(xiě)方法，調(diào)用后端接口：

search() { // 查詢
      this.loadList()
    },
    loadList() { // 加載列表
      this.tableData = []
      this.listLoading = true
      getPage(this.queryPage).then(response => {
        const { data } = response
        this.tableData = data.records
        this.total = parseInt(data.total)
        this.listLoading = false
      }).catch(response => {
        this.listLoading = false
      })
    },

在api文件夾對(duì)應(yīng)的js添加

export function getPage(data) {
  return request({
    url: '/operationMaintenance/getPage',
    method: 'post',
    data
  })
}

2.后端代碼

controller

@PostMapping("/getPage")
	public ResultData getPage(@RequestBody QueryEntry queryEntry) {
		IPage<OperationMaintenance> wappers = operationMaintenanceService.getPage(queryEntry);
		return ResultData.success("OK", wappers);
	}

serviceimpl

@Override
	public IPage<OperationMaintenance> getPage(QueryEntry queryEntry) {
		Page<OperationMaintenance> page = new Page<>(queryEntry.getPage(), queryEntry.getLimit());
		IPage<OperationMaintenance> iPage = operationMaintenanceMapper.getPage(page, queryEntry);
		return iPage;
	}

mapper

@Mapper
public interface OperationMaintenanceMapper extends BaseMapper<OperationMaintenance> {
    IPage<OperationMaintenance> getPage(Page<OperationMaintenance> page, @Param("queryEntry") QueryEntry queryEntry);
    OperationMaintenance getInfo(Long code);
    List<OperationMaintenance> getSelected2Page(@Param("queryEntry") QueryEntry queryEntry);
}

這是關(guān)鍵：

將前端傳來(lái)的時(shí)間數(shù)組，賦值給對(duì)應(yīng)的屬性；

vue可以使用插值表達(dá)式將后端傳來(lái)的兩個(gè)時(shí)間拼接在一起：

<el-table-column align="left" header-align="center" label="運(yùn)維開(kāi)始-至-結(jié)束日期" min-width="200">
        <template slot-scope="scope">
          <span>{{ scope.row.startTime }} 至 {{ scope.row.endTime }}</span>
        </template>
      </el-table-column>
