spring boot feign client获取HTTP 404

我目前正在检查如何在我的一个项目中使用Feign作为声明式REST客户端。

以下是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);
    }

此接口在一个服务中自动装配

@Autowired
SearchCabMsClient restService;

将EnableFeignClients添加到SpringBootApplication 

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

pom.xml中的依赖关系，父级等

我可以在为我的假装客户端调试spring create proxy时看到 我尝试在功能区的帮助下调用此服务，它工作正常 但是当我在我的假装客户端执行方法定义时。我正在 feign.FeignException：状态404阅读

在url中使用引用持有者有助于将其外部化并为每个环境进行配置。

如果您配置了URL，请双击检查其余端点。

您需要创建一个feign.ErrorDecoder。请阅读此以获取更多信息 https://github.com/spring-cloud/spring-cloud-openfeign/issues/118

您也可以在FeignClient注释定义中添加decode404=true。

答案 2 :(得分：0)

我有同样的问题。这是一个路由问题。只需在FeignClient的@RequestMapping路径的开头添加/。此外，路径变量未在路径中定义。我建议将它们定义为@RequestParam。然后，该路径是正确的，除了/开头。 

@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);
}

答案 3 :(得分：0)

大多数答案都建议将url属性设置为@FeignClient，但是当体系结构涉及向 Eureka Server注册服务（ Eureka Client ）< / em>，我认为使用url属性是没有自由的。

service-id 或 eureka-id 必须用于休息电话。
因此，使用client-side discovery architecture，

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

可能不再是
的可缩放解决方案 status 404 reading IFeignClient#someControllerMethod()错误。

我在client-side discovery architecture应用中遇到了同样的错误。问题是application.yml文件中的此项：

server:
  servlet:
    context-path: /myapp

删除它有助于解决问题，方法是正确的url。我的工作应用具有的确切声明：@FeignClient(name="${service-id}")

希望这可以帮助遇到类似问题的人。

答案 4 :(得分：0)

如果已设置server.servlet.context-path：##一些名称##，请将其删除并设置显示在EUREKA服务器主页上的应用程序名称。
