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

<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.
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.
