我已经在PCF和Eureka服务器中部署了我的2个Spring应用程序以供发现。我在应用程序中有@EnableEurekaClient，它们可以在PCF中的Eureka服务器中看到

当我使用FeignClient访问另一个应用程序时，我得到了一个错误

我的feignClient如下。我在这里发帖时重新命名了这些服务

代码语言：javascript
复制
@FeignClient(name = "my-feign-services")
public interface MyService {

    @RequestMapping(value = "/updateValues", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
    public String updateValues(@RequestBody ModelWrapper odelWrapper);

    @RequestMapping(value = "/dummy", method = RequestMethod.GET)
    public String dummy();

}

我还启用了Security，它还允许匿名请求。

代码语言：javascript
复制
protected void configure(HttpSecurity http) throws Exception {
        http.httpBasic().disable().authorizeRequests()
        .antMatchers("/my-feign-services/**").anonymous()
        .and()
        .authorizeRequests().anyRequest()
        .authenticated().and().csrf().disable();
    }

FeignClient没有在PCF中工作的任何原因。在本地主机上，它工作得很好，我可以很容易地在这两个服务之间进行通信，但在PCF中也是失败的。

我在配置类中使用FeignLogger启用了假装日志记录，并添加了假装客户端。日志中的位置是正确的，但是错误302和:content失败了。

最新情况：

在配置类中添加URL之后，它就工作了。在Cloud中平台团队获得Spring服务之前，这是一个暂停间隙安排。

我也尝试通过添加一个新的虚拟服务来进行调试，同样的FeignException也失败了。看起来，PCF中的服务注册中心有一些问题。我有一个备份代码，我将我的其他代码迁移到这里并进行了测试，运行良好。我能够在没有错误的情况下进行MS通信，并且也收到了响应.

302错误指示重定向。您能否尝试查看响应上的Location头？很有可能你没有假装被配置为跟随重定向。

不确定原因，但假装核心只考虑不出错，HTTP状态在200到299之间。

所有其他状态都抛出一个ErrorDecoder (除了具有特殊待遇的404 )

我也有同样的问题使用假的，我已经定制了我的FeignErrorHandler，以妥善处理它。

代码语言：javascript
复制
@Bean
public MyClient myClient() {
    return  Feign.builder()
            .errorDecoder(new CustomFeignErrorHandler()) // <== custom handler here
            .encoder(new JacksonEncoder())
            .decoder(new JacksonDecoder())
            .logger(new Slf4jLogger())
            .target(myClient.class, url);
}
