idea启动两个tomcat项目_IDEA同一项目启动多个实例

为了验证负载均衡，服务提供者(EurekaClientServiceProviderApplication)需要启动多个实例，当前已启动了一个实例，端口号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)

如何再启动一个呢？三板斧即可：

1、点开项目运行的配置编辑框

2、选择我们的项目，勾选Allow parallel run复选框

3、现在去修改application.properties的server.port为新端口8772，新实例启动了：

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)

运行框如果选择我们的项目的话，现在运行标志右下角那里会出现数字2：

题外话，parrellel是并行的意思
