前端展示和实现:
1. elmentUI表格的定义
2. JS请求参数改造
<!-- 列表 -->
<el-table v-loading="loading" :data="list" @sort-change="handleSortChange">
<el-table-column label="Expiry Date" prop="expiry_date" sortable>
<template slot-scope="{ column }">
<span>{{ column.label }}</span>
<el-icon v-if="column.property === currentSort.prop"
:class="currentSort.order === 'ascending' ?
'el-icon-arrow-up' : 'el-icon-arrow-down'">
</el-icon>
</template>
</el-table-column>
data() {
return {
currentSort: { // 当前排序状态
prop: '', // 排序的属性
order: '' // 排序顺序,可选值为 ascending 和 descending
},
....
methods: {
//捕捉事件
handleSortChange({ column, prop, order }) {
console.log(`排序属性: ${prop}, 排序方向: ${order}`);
this.currentSort.prop = prop;
this.currentSort.order = order;
this.getList()
// 在这里可以实现自定义排序逻辑,例如对tableData进行排序处理
},
....
//改造请求参数
addOrderFields(){
let sortingFields =[]
if(this.currentSort.prop !== ''){
let sortObj={
field:this.currentSort.prop,
order:''
}
if(this.currentSort.order == 'ascending'){
sortObj.order = 'asc'
}else{
sortObj.order ='desc'
}
sortingFields.push(sortObj)
this.queryParams.sortingFields= sortingFields
}
},
后端配合:
控制器:
POST方式和@RequestBody CertPageReqVO的配合
@PostMapping("/page")
@PreAuthorize("@ss.hasPermission('cert::query')")
public CommonResult<PageResult<CertRespVO>> getPage(@RequestBody CertPageReqVO pageVO ) {
return success(Service.getPageOfCertRespVo(pageVO));
}
//加入排序的接收参数
@Data
@EqualsAndHashCode(callSuper = true)
@ToString(callSuper = true)
public class CertPageReqVO extends PageParam {
//加入排序的接收参数
private Collection<SortingField> sortingFields;
Mapper实现:
改造selectPage()
IPage<CertDO> mpPage = MyBatisUtils.buildPage(reqVO,reqVO.getSortingFields());
@Mapper
public interface CertMapper extends BaseMapperX<CertDO> {
default PageResult<CertDO> selectPage(CertPageReqVO reqVO) {
LambdaQueryWrapperX<CertDO> ew= new LambdaQueryWrapperX<CertDO>()
.likeIfPresent(CertDO::getName, reqVO.getName())
.likeIfPresent(CertDO::getDescription, reqVO.getDescription())
.orderByDesc(CertDO::getId);
if (reqVO.PAGE_SIZE_NONE.equals(reqVO.getPageSize())) {
List<CertDO> list = selectList(ew);
return new PageResult<>(list, (long) list.size());
}
// MyBatis Plus 查询
IPage<CertDO> mpPage = MyBatisUtils.buildPage(reqVO,reqVO.getSortingFields());
selectPage(mpPage, ew);
// 转换返回
return new PageResult<>(mpPage.getRecords(), mpPage.getTotal());
}
已经实现的原理
