假装客户端获得请求，从微服务中抛出“方法不允许：请求方法'POST'不支持”

Question

我有一个带有spring后端的Vue.js应用程序，它通过一个虚假的客户端向一个“订单”微服务打电话。我有许多使用@PathVariable运行良好的GET请求，但我有一个GET请求，它可以传递任意数量的不同URL参数，并且定义了一个OrderListItemParameters类并将其添加到GET请求中，以便将这些参数传递给微服务。我可以看到请求正在发送到微服务，但它被拒绝，出现了“org.zalando.problem.spring.common.adviceTrait：Method Not alloved：request Method'post'Not supported”错误。

Ive确保feign客户机发送的OrderListItemParameters与微服务中期望的OrderListItemParameters匹配。在假客户端或微服务中都没有提到POST。我只有GET和PUTendpoint。

前端代码的Java后端：

@RestController
@RequestMapping("/api")
public class OrdersResource {

    ## THIS WORKS NO PROBLEM
    @GetMapping("/order/{orderId}")
    public @ResponseBody
    ResponseEntity<?> order(@PathVariable int orderId) throws Exception {
        return ResponseEntity.ok(orderClient.order(orderId));
    }


    ## THIS ENDPOINT IS THE ONE THAT FAILS
    @GetMapping("/order/list")
    public @ResponseBody
    ResponseEntity<?> orders(OrderListItemParameters orderListItemParams) {
        return ResponseEntity
           .ok(orderClient.getOrderList(orderListItemParams));
    }
}

@Component
@AuthorizedUserFeignClient(name = "orders")
public interface OrderClient {

    ## THIS WORKS NO PROBLEM
    @RequestMapping(method = RequestMethod.GET, value = "/api/order/pg/{orderId}")
    String order(@PathVariable("orderId") int orderId);

    ## THIS ENDPOINT IS THE ONE THAT FAILS
    @RequestMapping(method = RequestMethod.GET, value = "/api/order/list")
    String getOrderList(OrderListItemParameters orderListItemParams);
}

@JsonIgnoreProperties(ignoreUnknown = true)
@JsonInclude(JsonInclude.Include.NON_NULL)
public class OrderListItemParameters implements Serializable {

  private String searchPhrase;
  private String startDate;
  private String endDate;
  private ArrayList<String> sortKey;
  private ArrayList<String> sortValue;
  private Integer from;
  private Integer size;
}

(with getters, and setters) 

@Controller
@RequestMapping("/api")
public class OrderController {

  ## THIS WORKS NO PROBLEM
  @GetMapping("/order/pg/{orderId}")
  public @ResponseBody
  Order pgorder(@PathVariable int orderId) {
    return orderService.getPgOrderById(orderId);
  }

  ## THIS ENDPOINT IS THE ONE THAT FAILS
  @GetMapping("/order/list")
  public @ResponseBody
  ResponseEntity getOrderListItemsByMerchant(OrderListItemParameters orderListItemParams) {
    return orderService
        .getOrderListItemsByMerchant(orderListItemParams);
}

这是最终奏效的解决方案...

#Resource
@GetMapping("/order/list")
public @ResponseBody 
ResponseEntity<?> getOrderListItemsByMerchant(
    @RequestParam Map<String, Object> params) {
    // method code
}

#Feign Client
@RequestMapping(method = RequestMethod.GET, value = "/api/order/list")
ResponseEntity<String> getOrderList(@RequestParam Map<String, Object> params);

#Microservice Controller
@GetMapping("/order/list")
public @ResponseBody
ResponseEntity getOrderListItemsByMerchant(OrderListItemParameters orderListItemParams) {
    // method code
}

这样我就可以用动态参数获取URL，并且微服务仍然将请求视为get。

如果在请求的两边都有相同的定义对象会很好，但我根本无法使@SpringQueryMap或@QueryMap工作。
