SpringBoot RestTemplate http测试
spring-boot有关spring-boot测试的一些问题
这测试的时候主程序没有启动报错。错误如下
==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)==
这是因为测试的类写了url 的问题
具体的测试方法如下

主函数如下

这样可以认为是服务没有启动的原因，确实，当服务启动的时候，这个错误就会没有，这时候可以得出一个结论，就是Test的时候主函数是没有启动。需要启动主函数参能测试，
但是有个问题就是
当测试时url不要http://localhost:39900没有起动主函数一样能成功
[INFO][2018-04-29T22:40:02.455+0800][BusinessHandlerInterceptor.java:28] 【LOG HANDLER】 url=http://localhost:63857/migrate/test, traceId=null

但是端口号不是配置中的那个，还有就是每次端口号都会不一样，真的很奇怪；根本不按照配置来的，我觉得就是它没有都配置，但是默认端口不是8080吗，现在是每次都变，只是随机的一个端口号，从这一面又能看出，其实测试不用单独启动主函数的，测试类会启动，访问不了是因为，端口号不对，但是至于怎么解决目前没有想到. 但是也不影响开发，因为我认为服务端都没启动，客户端怎么能访问呢。
至于测试会加载springbootApplication但是端口不一样，没有执行加载端口类的结果。
