参数为空时的Spring cloud假动作

Question

@RequestMapping(
      path = "/TrackingServlet?CompanyName=Test&UserName=&BranchCode=",
      method = RequestMethod.GET,
      produces = MediaType.APPLICATION_JSON_VALUE
      )
  ResponseEntity<String> getInfo(
      @RequestParam("DocumentNumbers") String bill);

当它被调用时，url变成/trackingservlet？companyname=test&username&branchcode消除=符号，但是API需要这种格式，因为它是第三方API，我们不能修改它。

也试过

@RequestMapping(
      path = "/TrackingServlet?CompanyName=Test&UserName=",
      method = RequestMethod.GET,
      produces = MediaType.APPLICATION_JSON_VALUE
      )
  ResponseEntity<String> getInfo(
      @RequestParam("DocumentNumbers") String bill,
      @RequestParam(name = "BranchCode", required = true) String BranchCode);

  default ResponseEntity<String> getInfo(String bill) {
    return getInfo(bill, "");
  }

这甚至没有参数branchcode

Answer 1

如果您的URL是http://localhost:8080/trackingservlet/testing？username=pratik，请使用feign client：

@FeignClient(name = "tracking-servlet-service")
public interface TestFeignClient {

        @GetMapping("/trackingServlet/testing")
        public String getQueryParam(@RequestParam("userName") String name);

}

如果有2个或更多参数，则可以在@requestparam中添加相同参数

例如URLhttp://localhost:8080/trackingservlet/testing？username=pratik&companyname=test

 @FeignClient(name = "tracking-servlet-service")
    public interface TestFeignClient {

            @GetMapping("/trackingServlet/testing")
            public String getQueryParam(@RequestParam("userName") String name, 
                                        @RequestParam("companyName") String companyName);

    }
