jHipster："GreaterThan,LessThan"日期时间的搜索条件

Question

在我的jHipster项目中，我想按日期时间范围搜索行。我的代码片段是：

产品查询视图组件.html

<div class="input-group date" id='datetimepicker'>
    <input id="field_dateStart" #dateStart="ngbDatepicker" [(ngModel)]="criteriaByStartDate"/>
    <input id="field_dateEnd"  #dateEnd="ngbDatepicker" [(ngModel)]="criteriaByEndDate"/>
    <button (click)="findByCriteria()"
    </button>
</div>

组件类：

product-inquiry-view.component.ts

export class ProductInquiryViewComponent implements OnInit, OnDestroy {
criteriaByStartDate: string;
criteriaByEndDate: string;
..........
findByCriteria() {
    criteriaByStartDate: Date;
    criteriaByEndDate: Date;
    let criteriaByStartDate = this.criteriaByStartDate;
    let criteriaByEndDate = this.criteriaByEndDate
    this.productInquiryViewService
        .query({
            'piDate.greaterThan': criteriaByStartDate,
            'piDate.lessThan': criteriaByEndDate,
            'piDocnum.contains': this.criteriaByDocnum
        }).subscribe(
        (res: HttpResponse<IProductInquiryView[]>) => {
            this.productInquiryViews = res.body;
        },
        (res: HttpErrorResponse) => this.onError(res.message)
    );
}

控制器：

产品查询视图资源.java

@GetMapping("/product-inquiry-views")
@Timed
public ResponseEntity<List<ProductInquiryViewDTO>> getAllProductInquiryViews(ProductInquiryViewCriteria criteria) {
    log.debug("REST request to get ProductInquiryViews by criteria: {}", criteria);
    List<ProductInquiryViewDTO> entityList = productInquiryViewQueryService.findByCriteria(criteria);
    return ResponseEntity.ok().body(entityList);
}

我得到了例外：

 2019-04-15 12:48:45.910  WARN 24330 --- [  XNIO-2 task-1] .m.m.a.ExceptionHandlerExceptionResolver : Resolved exception caused by handler execution: org.springframework.validation.BindException:

to type [java.time.ZonedDateTime] for value 'Mon Apr 01 2019  00:00:00 GMT 0300'; nested exception is java.lang.IllegalArgumentException: Parse attempt failed for value [Mon Apr 01 2019 00:00:00 GMT 0300]]   enter code here

我看到"周一 Apr 01 2019 00：00：00 GMT 0300"不是解析到 ZoneDateTime 的相应字符串，所以我尝试以这种格式发送条件：

"2019-04-01T00:15:30+03:00[Europe/Moscow]";

相同的结果。

Answer 1

应该是：

this.productInquiryViewService
        .query({
            'piDate.greaterThan': criteriaByStartDate.toISOString(),
            'piDate.lessThan': criteriaByEndDate.toISOString(),
...
