我正在开发基于 Spring cloud consul 的 2 个应用程序。第一个称为 Hello1 并公开一个简单的 hello world Web 服务。第二个叫Hello2，尝试调用第一个应用暴露的web服务。这 2 个应用程序使用 consul 作为服务发现。

对于 Hello2，我有以下代码：

@RestController
@Slf4j
public class HelloWorldConsController {

@Autowired
private DiscoveryClient discoveryClient;

@Autowired
protected RestTemplate restTemplate;


protected String serviceUrl;

@RequestMapping("/hello2")
public String hello() {
    log.info("Hello calls ");

    return restTemplate.getForObject("http://hello1-Example/hello1",   String.class);
 }
}

配置文件（yml）：

 spring:
  application:
   name: hello2-Example
 profiles:
 active: native

  cloud:
   consul:
    config:
     enabled: true
   host: localhost
   port: 8500

对于 Hello1 应用程序：

 @Controller
 @RestController
 public class HelloWorldController {

  @RequestMapping("/hello1")
  public String hello() {
    return "Hello1";
  }

}

配置文件（yml）：

 spring:
  application:
   name: hello1-Example
 profiles:
 active: native

  cloud:
   consul:
    config:
     enabled: true
   host: localhost
   port: 8500

这是我的依赖项：

    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-parent</artifactId>
    <version>Angel.SR3</version>

        <artifactId>lombok</artifactId>
        <version>${lombok.version}</version>
    </dependency>
</dependencies>

但是，当我调用 hello 2 应用程序http://localhost:1234/hello2时，它给了我以下错误：

org.springframework.web.client.HttpClientErrorException: 404 NOT_FOUND
at org.springframework.web.client.DefaultResponseErrorHandler.handleError(DefaultResponseErrorHandler.java:91)
