Java Spring MVC responsebody RestTemplate连接拒绝本地主机

RestTemplate不工作，正在引发连接被拒绝异常。我不确定我的个人电脑有什么问题，因为我使用无线互联网，而且没有代理

Junit测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:testContext.xml")
public class RestServiceTest {

    @Autowired
    private RestTemplate restTemplate;

    @Test
    public void testRestService() {
        ResponseEntity<String> response = restTemplate.getForEntity("http://localhost:8080/hello/world", String.class);

        String responseTask = response.getBody();
    }
}

您的应用程序上下文是什么？它是您的web服务器下的根吗？我尝试了所有可能与上下文和主机的组合，例如localhost、127.0.0.1和本地ip。您的web应用程序的名称是什么？你试过添加你的URL吗？有人能帮忙吗？我以为使用RESTTemplate会启动内存中的jetty，但现在我发现它不会，我需要自己启动服务器。如果我的理解是正确的，或者没有更好的方法，这个问题就过时了。

    @RequestMapping(value = "/hello/{message}", method = RequestMethod.GET)
    public @ResponseBody String sayHello(@PathVariable String message) {
        return "Hello "+message;
