spring boot feign client getting HTTP 404

Question

I am currently just checking how to use Feign as Declarative REST client in one of my project.

following is Feign Client

@FeignClient(name = "SEARCHCABMS",configuration = AppFeignConfiguration.class)
       public interface SearchCabMsClient {

        @RequestMapping(value = "api/searchcab/locationcabtimedetail/search/getCabForLocationAfterTimeSlot", method = RequestMethod.GET)
        String  searchCabDetails(@PathVariable("fromDate") String fromDate, 
                                @PathVariable("locationId") long locationId,
                                @PathVariable("isdeleted") byte isdeleted,
                                @PathVariable("hourforbooking")int hourforbooking);
    }

This interface is autowired in one service

@Autowired
SearchCabMsClient restService;

Added EnableFeignClients to SpringBootApplication

@EnableFeignClients(basePackages = {"com.gp.cabbooking.services.feign"})

Dependencies,parent etc in pom.xml

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.3.5.RELEASE</version>
</parent>

dependency

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.cloud</groupId>

</dependency>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-feign</artifactId>
</dependency>

I can able to see while debugging spring create proxy for my feign client i tried calling this service with the help of ribbon and it is working fine but when i execute method define in my feign client . i am getting feign.FeignException: status 404 reading

feign.FeignException: status 404 reading SearchCabMsClient#searchCabDetails(String,long,byte,int)

You need to create a feign.ErrorDecoder. Please read this for more information https://github.com/spring-cloud/spring-cloud-openfeign/issues/118

You can also add decode404=true in your FeignClient annotation definition.

This answer deserved to be accepted. In case of `Feign.builder()`, just add `.decode404`. – dgregory Sep 23 '19 at 04:23
Adding `decode404 = true` in `@FeignClient` resolved the issue for me. What is the meaning of decode404 boolean? – firstpostcommenter Aug 17 '22 at 21:16

Have you defined the url of the service you reach to using this feign client? 404 is a not found issue.

  @FeignClient(name = "SEARCHCABMS", url = "${SEARCHCABMS.service.url}", 
  configuration = ClientConfiguration.class)
  public interface SearchCabMsClient {

  }

Having a reference holder in url helps to externalize it and configure for each environment.

If you did configured the URL, double the check the rest endpoint.

spring cloud feign should be invoked based on the app name with out using url right? – Abdul Jul 24 '19 at 10:59
I am not sure what you mean by that? As far as this answer goes, feign client either from openfeign or spring cloud, doesn't matter. Its just a http client implementation. So you do need to provide the URL it needs to connect to. – Seetha Aug 02 '19 at 21:42

I had the same problem. It is a routing issue. Just add / at the start in @RequestMapping path in FeignClient. Also, path variables are not defined in the path. I recommend define they as @RequestParam. Then the path is correct except / at the start.

@FeignClient(name = "SEARCHCABMS",configuration = AppFeignConfiguration.class)
   public interface SearchCabMsClient {

    @RequestMapping(value = "/api/searchcab/locationcabtimedetail/search/getCabForLocationAfterTimeSlot/{fromDate}/{locationId}/{isdeleted}/{hourforbooking}", method = RequestMethod.GET)
    String  searchCabDetails(@PathVariable("fromDate") String fromDate, 
                            @PathVariable("locationId") long locationId,
                            @PathVariable("isdeleted") byte isdeleted,
                            @PathVariable("hourforbooking")int hourforbooking);
}

Most of the answers suggest putting the url attribute to @FeignClient, but when the architecture involves registering the service (Eureka Client) with the Eureka Server, I think, there is no liberty to use the url attribute.

It is the service-id or the eureka-id that has to be used for the purpose of rest calls.
So, with the client-side discovery architecture,

@FeignClient(name = "service-id", url = "${service.url}", configuration=SomeConfig.class)

may no longer be the scalable solution to the
status 404 reading IFeignClient#someControllerMethod() error.

I faced the same error in my client-side discovery architecture app. The issue was this entry in the application.yml file:

server:
  servlet:
    context-path: /myapp

Removing it helped resolve the issue by correct url. The exact declaration that my working app has: @FeignClient(name="${service-id}")

Hope this helps someone with similar issue.

Instead of removing context-path from application.yml you could have added /myapp as a prefix path to declarative methed of Feign client for example @RequestMapping(value = "/myapp/remaining path", method = RequestMethod.GET) String feignMethod(...); — abhinav kumar, May 31 '21 at 15:23

If you have set the server.servlet.context-path: ##some name##, remove it and set the application name displayed in EUREKA server home page.
