Question

我正在开发基于Spring云领事的2个应用程序。第一个调用Hello1并公开一个简单的hello world Web服务。第二个叫做Hello2，尝试调用第一个应用程序公开的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：

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

    <dependency>

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

但是，当我调用hello 2 application http://localhost:1234/hello2时，它会给我以下错误：

org.springframework.web.client.HttpClientErrorException: 404 NOT_FOUND
