Question

我是Jhipster的新手，我也不是一个经验丰富的开发人员。所以我已经生成了一个Jhipster项目，需要一个带有动态column-filtering选项的简单表。我已经看到了Jhipster在backend-side上生成的所有内容。

所以我有生成的Class CustomerQueryService.java

    @Transactional(readOnly = true)
public List<Customer> findByCriteria(CustomerCriteria criteria) {
    log.debug("find by criteria : {}", criteria);
    final Specifications<Customer> specification = createSpecification(criteria);
    return customerRepository.findAll(specification);
}

/**
 * Return a {@link Page} of {@link Customer} which matches the criteria from the database
 * @param criteria The object which holds all the filters, which the entities should match.
 * @param page The page, which should be returned.
 * @return the matching entities.
 */
@Transactional(readOnly = true)
public Page<Customer> findByCriteria(CustomerCriteria criteria, Pageable page) {
    log.debug("find by criteria : {}, page: {}", criteria, page);
    final Specifications<Customer> specification = createSpecification(criteria);
    return customerRepository.findAll(specification, page);
}

/**
 * Function to convert CustomerCriteria to a {@link Specifications}
 */
private Specifications<Customer> createSpecification(CustomerCriteria criteria) {
    Specifications<Customer> specification = Specifications.where(null);
    if (criteria != null) {
        if (criteria.getId() != null) {
            specification = specification.and(buildSpecification(criteria.getId(), Customer_.id));
        }
        if (criteria.getLastName() != null) {
            specification = specification.and(buildStringSpecification(criteria.getLastName(), Customer_.lastName));
        }
        if (criteria.getName() != null) {
            specification = specification.and(buildStringSpecification(criteria.getName(), Customer_.name));
        }
        if (criteria.getPhoneNumber() != null) {
            specification = specification.and(buildRangeSpecification(criteria.getPhoneNumber(), Customer_.phoneNumber));
        }
        if (criteria.getProvider() != null) {
            specification = specification.and(buildStringSpecification(criteria.getProvider(), Customer_.provider));
        }
        if (criteria.getVoNumber() != null) {
            specification = specification.and(buildRangeSpecification(criteria.getVoNumber(), Customer_.voNumber));
        }
        if (criteria.getTransactionType() != null) {
            specification = specification.and(buildStringSpecification(criteria.getTransactionType(), Customer_.transactionType));
        }
        if (criteria.getKomponent() != null) {
            specification = specification.and(buildStringSpecification(criteria.getKomponent(), Customer_.komponent));
        }
        if (criteria.getActivationDate() != null) {
            specification = specification.and(buildRangeSpecification(criteria.getActivationDate(), Customer_.activationDate));
        }
        if (criteria.getSimNumber() != null) {
            specification = specification.and(buildRangeSpecification(criteria.getSimNumber(), Customer_.simNumber));
        }
        if (criteria.getOrderNumber() != null) {
            specification = specification.and(buildRangeSpecification(criteria.getOrderNumber(), Customer_.orderNumber));
        }
        if (criteria.getTariff() != null) {
            specification = specification.and(buildStringSpecification(criteria.getTariff(), Customer_.tariff));
        }
        if (criteria.getOption() != null) {
            specification = specification.and(buildStringSpecification(criteria.getOption(), Customer_.option));
        }
        if (criteria.getHardware() != null) {
            specification = specification.and(buildStringSpecification(criteria.getHardware(), Customer_.hardware));
        }
        if (criteria.getImei() != null) {
            specification = specification.and(buildRangeSpecification(criteria.getImei(), Customer_.imei));
        }
        if (criteria.getPurchasingPrice() != null) {
            specification = specification.and(buildRangeSpecification(criteria.getPurchasingPrice(), Customer_.purchasingPrice));
        }
        if (criteria.getRetailPrice() != null) {
            specification = specification.and(buildRangeSpecification(criteria.getRetailPrice(), Customer_.retailPrice));
        }
        if (criteria.getProvision() != null) {
            specification = specification.and(buildRangeSpecification(criteria.getProvision(), Customer_.provision));
        }
        if (criteria.getMarge() != null) {
            specification = specification.and(buildRangeSpecification(criteria.getMarge(), Customer_.marge));
        }
        if (criteria.getHwWkz() != null) {
            specification = specification.and(buildRangeSpecification(criteria.getHwWkz(), Customer_.hwWkz));
        }
        if (criteria.getPaid() != null) {
            specification = specification.and(buildSpecification(criteria.getPaid(), Customer_.paid));
        }
        if (criteria.getEmployee() != null) {
            specification = specification.and(buildStringSpecification(criteria.getEmployee(), Customer_.employee));
        }
        if (criteria.getComment() != null) {
            specification = specification.and(buildStringSpecification(criteria.getComment(), Customer_.comment));
        }
    }
    return specification;
}

}

并在我的 cusotmer.component.ts

中

 searchByField(fieldName, fieldValue) {
    if (!fieldValue) {
        return this.clear();
    }
    this.page = 0;
    this.fieldName = fieldName,
    this.fieldValue = fieldValue;
    this.router.navigate(['/customer', {
        fieldName: this.fieldName,
        fieldValue: this.fieldValue,
        page: this.page,
        sort: this.predicate + ',' + (this.reverse ? 'asc' : 'desc')
    }]);
    this.loadByField();
}

并在 customer.service.ts

中

    searchByField(req?: any): Observable<HttpResponse<Customer[]>> {
    const options = createRequestOption(req);
    return this.http.get<Customer[]>(this.resourceSearchFieldUrl, { params: options, observe: 'response' })
        .map((res: HttpResponse<Customer[]>) => this.convertArrayResponse(res));
}

我现在想要的是组合表中每列的Searchqueries并将其发送到elasticsearch api并获取正确的URL以填充搜索，如下所示：

但遗憾的是我无法合并搜索参数，也不知道如何修改它。我也将从最佳实践开始，也将使用Jhipster生成的类，因为我认为这是最好的方法。任何人都知道如何修改它？非常感谢您提前阅读这个长期问题。

尝试：

searchByField(fieldName, fieldValue) {
    if (!fieldValue) {
        return this.clear();
    }
    this.page = 0;
    this.router.navigate(['/customer', {
        this.fieldName:this.fieldValue; //   'customerName.contains': 'Jackson',
        page: this.page,
        sort: this.predicate + ',' + (this.reverse ? 'asc' : 'desc')
    }]);
    this.loadByField();
}

JHipster - 使用来自elasticsearch的API调用对实体进行动态过滤 - 如何使用angular5以propper方式实现它？
