Spring Cloud Feign report 404 - spring-boot

Question

I use Eureka to register a service and use Feign to discover services, but if I don't add URL parameters, the system will report 404 exceptions.
And my code id below that does not work :
#FeignClient(name = "CRAWLER-SERVICE")
And Below code works :
#FeignClient(name = "crawler-service", url = "http://192.168.199.229:8091/crawler")
Stack trace :
feign.FeignException: status 404 reading CrawlerServiceApi#queryAllConditions(String,String)

The eureka configuration is：
server:
port: 8761
eureka:
instance:
hostname: localhost
client:
register-with-eureka: false
fetch-registry: false
serviceUrl:
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
server:
enable-self-preservation: false
wait-time-in-ms-when-sync-empty: 0
And the client configuration is：
eureka:
instance:
lease-expiration-duration-in-seconds: 2
lease-renewal-interval-in-seconds: 1
client:
serviceUrl:
defaultZone: http://127.0.0.1:8761/eureka/
The server code:
#RestController
#RequestMapping("/api/crawler")
public class CrawlerConditonApi {
private final CrawlerConditonService crawlerConditonService;
#Autowired
public CrawlerConditonApi(CrawlerConditonService crawlerConditonService) {
this.crawlerConditonService = crawlerConditonService;
}
#GetMapping("/conditions")
public String queryAllConditions(String belongDatasource, String conditionStatus) {
return crawlerConditonService.queryAllCondition(belongDatasource, conditionStatus);
}
#PostMapping("/conditions")
public String insertConditon(String params, String belongDatasource) {
return crawlerConditonService.insertConditon(params, belongDatasource);
}
#PutMapping("/conditions/{id}/status/{status}")
public String updateCondition(#PathVariable("id") String id, #PathVariable("status") String status) {
return crawlerConditonService.updateCondition(id, status);
}
}
THE CLIENT CODE:
#FeignClient(name = "CRAWLER-SERVICE")
public interface CrawlerServiceApi {
#RequestMapping(value = "/api/papersources/", method = RequestMethod.GET)
String queryAllSource();
#RequestMapping(value = "/api/papersources/{id}/status/{status}", method = RequestMethod.PUT)
String updateSource(#PathVariable("id") String id, #PathVariable("status") String status);
#RequestMapping(value = "/api/crawler/conditions", method = RequestMethod.GET)
String queryAllConditions(#RequestParam("belongDatasource") String belongDatasource,
#RequestParam("conditionStatus") String conditionStatus);
#RequestMapping(value = "/api/crawler/conditions", method = RequestMethod.POST)
String insertConditon(#RequestParam("params") String params,
#RequestParam("belongDatasource") String belongDatasource);
#RequestMapping(value = "/api/crawler/conditions/{id}/status/{status}", method = RequestMethod.PUT)
String updateCondition(#PathVariable("id") String id, #PathVariable("status") String status);
}
And I use in Controller:
#RestController
public class CrawlerConditionController {
private final CrawlerServiceApi crawlerServiceApi;
#Autowired
public CrawlerConditionController(CrawlerServiceApi crawlerServiceApi) {
this.crawlerServiceApi = crawlerServiceApi;
}
#GetMapping("/conditions/query")
public AbstractResult queryAllSource(#RequestParam("belongDatasource") String belongDatasource,
#RequestParam("conditionStatus") String conditionStatus) {
return ApiInvokeRspUtil.returnDataRowsInvokeRsp("CRL00000",
crawlerServiceApi.queryAllConditions(belongDatasource, conditionStatus));
}
#PostMapping("/conditions/add")
public AbstractResult addConditon(#RequestParam("paramJson") String paramJson,
#RequestParam("belongDataSource") String belongDataSource) {
return ApiInvokeRspUtil.returnDataRowsInvokeRsp("CRL00000",
crawlerServiceApi.insertConditon(paramJson, belongDataSource));
}
#PostMapping("/conditions/{id}/status/{status}")
public AbstractResult updateConditon(#PathVariable("id") String id,
#PathVariable("status") String status) {
return ApiInvokeRspUtil.returnDataRowsInvokeRsp("CRL00000",
crawlerServiceApi.updateCondition(id, status));
}
}

Answer 1

It's an old question, still posting my answer so it may help someone else as I had the same problem and finally was able to solve it.
It happened due to server.context which is set to crawler. Since this effectively adds a new url segment, you need to change your feign client to below (mind the context added after service name)
#FeignClient(name = "CRAWLER-SERVICE/crawler")
Or you need to change the RequestMapping to something like below (again mind the context added before service url):
#RequestMapping("crawler/<rest of the url>")
