SpringBoot RestTemplate http測試
spring-boot有關spring-boot測試的一些問題
這測試的時候主程序沒有啟動報錯。錯誤如下
==org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://localhost:39900/migrate/test": Connect to localhost:39900 [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:39900 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect
at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:666)
at org.springframework.web.client.RestTemplate.execute(RestTemplate.java:613)==
這是因為測試的類寫了url 的問題
具體的測試方法如下

package api;import com.hera.WebApplication;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.boot.test.context.SpringBootTest;import org.springframework.boot.test.web.client.TestRestTemplate;import org.springframework.http.ResponseEntity;import org.springframework.test.context.junit4.SpringRunner;import java.util.Map;@RunWith(SpringRunner.class)@SpringBootTest(classes = WebApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)@EnableAutoConfigurationpublic class Test { @Autowired public TestRestTemplate restTemplate; @org.junit.Test public void home(){ String url="http://localhost:39900/migrate/test"; Map map=restTemplate.getForObject(url,Map.class); System.out.println(map.get("red")); }} |
主函數如下

@ComponentScan(basePackages={"com.hera"})@SpringBootApplication@EnableJpaRepositories(repositoryFactoryBeanClass = ExtJpaRepositoryFactoryBean.class)public class WebApplication { public static void main(String[] args) { SpringApplication.run(WebApplication.class, args); }} |
這樣可以認為是服務沒有啟動的原因，確實，當服務啟動的時候，這個錯誤就會沒有，這時候可以得出一個結論，就是Test的時候主函數是沒有啟動。需要啟動主函數參能測試，
但是有個問題就是
當測試時url不要http://localhost:39900沒有起動主函數一樣能成功
[INFO][2018-04-29T22:40:02.455+0800][BusinessHandlerInterceptor.java:28] 【LOG HANDLER】 url=http://localhost:63857/migrate/test, traceId=null
..............................

但是端口號不是配置中的那個，還有就是每次端口號都會不一樣，真的很奇怪；根本不按照配置來的，我覺得就是它沒有都配置，但是默認端口不是8080嗎，現在是每次都變，只是隨機的一個端口號，從這一面又能看出，其實測試不用單獨啟動主函數的，測試類會啟動，訪問不了是因為，端口號不對，但是至于怎么解決目前沒有想到. 但是也不影響開發，因為我認為服務端都沒啟動，客戶端怎么能訪問呢。
至于測試會加載springbootApplication但是端口不一樣，沒有執行加載端口類的結果。
