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)

Answer 1

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.
