org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://localhost:8080/v1/apc"

问题

当我运行测试时，我得到了以下异常信息：

  1. org.springframework.web.client.ResourceAccessException: 在GET请求“http://localhost:8080/v1/apc”时发生I/O错误：连接到localhost:8080 [localhost/127.0.0.1、localhost/0:0:0:0:0:0:0:1] 失败：拒绝连接：连接；嵌套异常是org.apache.http.conn.HttpHostConnectException：连接到localhost:8080 [localhost/127.0.0.1、localhost/0:0:0:0:0:0:0:1] 失败：拒绝连接：连接
  2. 	at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:785)
  3. 	...
  4. Caused by: org.apache.http.conn.HttpHostConnectException: 连接到localhost:8080 [localhost/127.0.0.1、localhost/0:0:0:0:0:0:0:1] 失败：拒绝连接：连接
  5. 	at org.apache.http.impl.conn.DefaultHttpClientConnectionOperator.connect(DefaultHttpClientConnectionOperator.java:156)
  6. 	...
  7. Caused by: java.net.ConnectException: 拒绝连接：连接
  8. 	at java.net.DualStackPlainSocketImpl.connect0(Native Method)
  9. 	...

有人可以帮助我找出问题可能是什么吗？

英文:

I have a controller Test class like following

  1. @ExtendWith(SpringExtension.class)
  2. @ContextConfiguration(classes = {ApiController.class,TableService.class, CommonService.class},
  3.         loader = AnnotationConfigContextLoader.class)
  4. @TestPropertySource(locations = {"classpath:properties/test/application-test.properties"})
  5. @ActiveProfiles(profiles = "test")
  6. @SpringBootTest(webEnvironment = WebEnvironment.DEFINED_PORT)
  7. public class ApiControllerTest {
  9.     @Autowired
  10.     private TestRestTemplate testRestTemplate;
  11.     
  12.    @Test
  13.     public void successTypeHttp200Ok() throws JsonParseException, JsonMappingException, IOException {
  14.     	ResponseEntity<String> response = testRestTemplate.
  15.     	    	  getForEntity("/v1/apc?name=test", String.class);            
  16.     }
  18. }

When I run the test I am getting the following exception

  1. org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://localhost:8080/v1/apc": Connect to localhost:8080 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect; nested exception is org.apache.http.conn.HttpHostConnectException: Connect to localhost:8080 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect

Can someone help me out what could be the issue?

答案1

得分: 1

测试似乎编写得很好，但我认为有一件事是错误的。尝试删除@SpringBootTest(webEnvironment = WebEnvironment.DEFINED_PORT)行中的WebEnvironment.DEFINED_PORT，然后重新运行你的测试。默认情况下，将使用WebEnvironment.MOCK。

实际上，你的测试不应该绑定到特定的端口，因为当测试运行时，同一端口可能正在运行另一个应用程序，这可能会在将来引发一些问题。

如果不起作用，请告诉我。

英文:

The test seems to be written well, but one thing, I suppose, is wrong. Try to delete WebEnvironment.DEFINED_PORT in the line @SpringBootTest(webEnvironment = WebEnvironment.DEFINED_PORT) and rerun your test. By default, WebEnvironment.MOCK will be used.

Actually your tests should not be bounded to specific ports because when tests are being ran another application may be running on the same port and this can cause some problems in the future.

Let me know if it doesn't work.
