SpringBoot RestTemplate http測(cè)試
spring-boot有關(guān)spring-boot測(cè)試的一些問(wèn)題
這測(cè)試的時(shí)候主程序沒(méi)有啟動(dòng)報(bào)錯(cuò)。錯(cuò)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?yàn)闇y(cè)試的類(lèi)寫(xiě)了url 的問(wèn)題
具體的測(cè)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")); }} |

這樣可以認(rèn)為是服務(wù)沒(méi)有啟動(dòng)的原因，確實(shí)，當(dāng)服務(wù)啟動(dòng)的時(shí)候，這個(gè)錯(cuò)誤就會(huì)沒(méi)有，這時(shí)候可以得出一個(gè)結(jié)論，就是Test的時(shí)候主函數(shù)是沒(méi)有啟動(dòng)。需要啟動(dòng)主函數(shù)參能測(cè)試，
但是有個(gè)問(wèn)題就是
當(dāng)測(cè)試時(shí)url不要http://localhost:39900沒(méi)有起動(dòng)主函數(shù)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
..............................
[INFO][2018-04-29T22:40:02.976+0800][BusinessHandlerInterceptor.java:48] 請(qǐng)求參數(shù)==> url: http://localhost:63857/migrate/test, spend：0.521秒, contentType: null, params: null, body_params: {}
green
但是端口號(hào)不是配置中的那個(gè)，還有就是每次端口號(hào)都會(huì)不一樣，真的很奇怪；根本不按照配置來(lái)的，我覺(jué)得就是它沒(méi)有都配置，但是默認(rèn)端口不是8080嗎，現(xiàn)在是每次都變，只是隨機(jī)的一個(gè)端口號(hào)，從這一面又能看出，其實(shí)測(cè)試不用單獨(dú)啟動(dòng)主函數(shù)的，測(cè)試類(lèi)會(huì)啟動(dòng)，訪問(wèn)不了是因?yàn)椋丝谔?hào)不對(duì)，但是至于怎么解決目前沒(méi)有想到. 但是也不影響開(kāi)發(fā)，因?yàn)槲艺J(rèn)為服務(wù)端都沒(méi)啟動(dòng)，客戶端怎么能訪問(wèn)呢。
至于測(cè)試會(huì)加載springbootApplication但是端口不一樣，沒(méi)有執(zhí)行加載端口類(lèi)的結(jié)果。
