@RestControllerpublic class TestService {    private TestApi computeClient;        private static final String SERVER_NAME = "eureka.client"; @Autowired private DiscoveryClient discoveryClient;  @RequestMapping(value = "/gethello/{name}", method = RequestMethod.GET)    public String getHello(@PathVariable("name") String name) {    Builder feignBuilder= Feign.builder().decoder(new ResponseEntityDecoder(new SpringDecoder(new ObjectFactory
     
      (){   public HttpMessageConverters getObject() throws BeansException {    return new HttpMessageConverters();   }  }))).client(new ApacheHttpClient()).contract(new SpringMvcContract());  computeClient = feignBuilder.target(TestApi.class,discoveryClient.getInstances(SERVER_NAME).get(0).getUri().toString());        return computeClient.testHello(name);    }}
     

主要是通过discoveryClient.getInstances(SERVER_NAME).get(0).getUri()获取注册中心实例地址。
