Question

如果在以下位置正确加载了值，我不会在Angular Service中从前到后获取我的参数：如果embarno没有到达后端，这个相同的代码在Jhipster 4.4.1的垄断应用程序中正常工作。现在我还没有迁移，它是在4.6.2版本的微服务中，我不知道它是否改变了发送参数的语法。

控制器：

  this.contactoService.byCliente(this.cliente.id).subscribe(
            result => { this.contactos = result; },
            error => { console.debug(error); });

服务：

byCliente(clienteId?: any): Observable<Contacto[]> {
    let params = new URLSearchParams();
    params.set('clienteId', clienteId);
    return this.http.get(this.resourceUrl + "/bycliente", { search: params }).map((res: Response) => {
        return res.json();
    });
}

返回（微服务）：

 @GetMapping("/contactos/bycliente")
 @Timed
 public ResponseEntity<List<ContactoDTO>> getAllContactosByCliente(@RequestParam String clienteId) {
   log.debug("REST request to get a page of Contactos");
   List<ContactoDTO> list = contactoService.findContactosByCliente(clienteId);
   return new ResponseEntity<>(list, HttpStatus.OK);
 }

错误：

An unexpected error occurred: Required String parameter 'clienteId' is not present org.springframework.web.bind.MissingServletRequestParameterException: Required String parameter 'clienteId' is not present

Try to put the parameter directly in the url when calling the api in your Service :

byCliente(clienteId?: any): Observable<Contacto[]> {
    let params = new URLSearchParams();
    return this.http.get(this.resourceUrl + "/bycliente?clienteId="+clienteId).map((res: Response) => {
        return res.json();
    });
}

发送参数微服务。 Jhipster 4.6.2
