所以，我使用简单的 RestTemplate 和直接 ip:port 到我的服务：

restTemplate.exchange("http://localhost:8081/user", HttpMethod.GET, null, String.class, new HashMap<String, String>());

但现在我想让它意识到尤里卡。所以，所以我@LoadBalanced在我的 restTemplate 上面添加了。myapp当然这里是eureka中注册的服务名称。

@Autowired
@LoadBalanced
public OAuth2RestTemplate restTemplate;

...
restTemplate.exchange("http://myapp/user", HttpMethod.GET, null, String.class, new HashMap<String, String>());
...

但这打破了：

我是否必须在以下位置添加任何额外的依赖项：

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-security</artifactId>
  <version>1.0.1.RELEASE</version>
</dependency>
<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-eureka</artifactId>
  <version>${spring.cloud.version}</version>
</dependency>

?
