springboot的打包方式有很多种。有打成war的，有打成jar的，也有直接提交到github，通过jekins进行打包部署的。这里主要介绍如何打成jar进行部署。不推荐用war，因为springboot适合前后端分离，打成jar进行部署更合适。
首先需要在application.properties当中配置端口

server.port=8080
# http://localhost:8088/swagger-ui.html

marven的配置文件

                </configuration>
            </plugin>
        </plugins>
    </build>


</project>

注意最下面的build这块一定要配置否则打jar的时候会说找不到主类

在启动类当中加上extends SpringBootServletInitializer并重写configure方法，这是为了打包springboot项目用的。

package com.weixin;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class SmallsystemApplication extends SpringBootServletInitializer

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

    @Override//为了打包springboot项目
    protected SpringApplicationBuilder configure(
            SpringApplicationBuilder builder) 
        return builder.sources(this.getClass());

然后按照顺序运行mvn clean再mvn install,我是用idea执行的
