ServerPortInfoApplicationContextInitializer (Spring Boot API)

java.lang.Object
- org.springframework.boot.web.context.ServerPortInfoApplicationContextInitializer

所有已实现的接口:
EventListener, org.springframework.context.ApplicationContextInitializer<org.springframework.context.ConfigurableApplicationContext>, org.springframework.context.ApplicationListener<WebServerInitializedEvent>
```
public class ServerPortInfoApplicationContextInitializer
extends Object
implements org.springframework.context.ApplicationContextInitializer<org.springframework.context.ConfigurableApplicationContext>, org.springframework.context.ApplicationListener<WebServerInitializedEvent>
```
ApplicationContextInitializer that sets Environment properties for the ports that WebServer servers are actually listening on. The property "local.server.port" can be injected directly into tests using @Value or obtained via the Environment.
If the WebServerInitializedEvent has a server namespace , it will be used to construct the property name. For example, the "management" actuator context will have the property name "local.management.port".
Properties are automatically propagated up to any parent context.
从以下版本开始:
