spring-boot怎么更改默认的端口号

package com.springboot1;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer;
import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;

@SpringBootApplication
public class Springboot1Application implements EmbeddedServletContainerCustomizer {

public static void main(String[] args) {
SpringApplication.run(Springboot1Application.class, args);
}

@Override
public void customize(ConfigurableEmbeddedServletContainer configurableEmbeddedServletContainer) {
configurableEmbeddedServletContainer.setPort(8011);
}
}

方法二：更加简单

在src/resource下增加文件application.properties

加入server.port=8081

即可
