IDEA同一項目啟動多個實例

　　為了驗證負載均衡，服務提供者（EurekaClientServiceProviderApplication）需要啟動多個實例，當前已啟動了一個實例，端口號8762：

2019-07-18 16:06:58.626  INFO [a-bootiful-client,,,] 43400 --- [           main] o.s.b.w.embedded.tomcat.TomcatWebServer  : Tomcat started on port(s): 8762 (http) with context path ''
2019-07-18 16:06:58.627  INFO [a-bootiful-client,,,] 43400 --- [           main] .s.c.n.e.s.EurekaAutoServiceRegistration : Updating port to 8762
2019-07-18 16:06:58.629  INFO [a-bootiful-client,,,] 43400 --- [           main] h.EurekaClientServiceProviderApplication : Started EurekaClientServiceProviderApplication in 7.985 seconds (JVM running for 9.474)

　　如何再啟動一個呢？三板斧即可：

　　1、點開項目運行的配置編輯框

　　2、選擇我們的項目，勾選Allow parallel run復選框

　　3、現在去修改application.properties的server.port為新端口8772，新實例啟動了：

2019-07-18 17:00:07.374  INFO [a-bootiful-client,,,] 48872 --- [           main] o.s.b.w.embedded.tomcat.TomcatWebServer  : Tomcat started on port(s): 8772 (http) with context path ''
2019-07-18 17:00:07.376  INFO [a-bootiful-client,,,] 48872 --- [           main] .s.c.n.e.s.EurekaAutoServiceRegistration : Updating port to 8772
2019-07-18 17:00:07.378  INFO [a-bootiful-client,,,] 48872 --- [           main] h.EurekaClientServiceProviderApplication : Started EurekaClientServiceProviderApplication in 9.425 seconds (JVM running for 10.974)

　　運行框如果選擇我們的項目的話，現在運行標志右下角那里會出現數字2：

 

　　題外話，parrellel是並行的意思。
