上面的一大堆報錯，原因就是下面這個報錯簡介引起的
The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.
可以通過update端口解決端口衝突問題：
1. Update 通過 application.properties
/src/main/resources/application.properties
server.port=8085
2. Update 通過 application.yml
/src/main/resources/application.yml
server:
port: 8085
3. Update 通過 WebServerFactoryCustomizer
創建一個 CustomContainer 類, 實現WebServerFactoryCustomizer 接口, 繼承它的自定義方法並且設值你的新端口. 這個會覆蓋application.yml和application.properties裏面的端口
package org.websparrow;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.boot.web.servlet.server.ConfigurableServletWebServerFactory;
import org.springframework.stereotype.Component;
@Component
public class CustomContainer implements WebServerFactoryCustomizer<ConfigurableServletWebServerFactory> {
@Override
public void customize(ConfigurableServletWebServerFactory factory) {
factory.setPort(8085);
}
}
