1.首先在pom.xml文件中要有Springboot的maven依赖;

<build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>

--------------------

2.maven - Lifecyle - package 双击`package`，开始打包

--------------------

1.  package完成以后,项目目录中，`target`文件夹下会生成一个`.jar`包;

--------------------

1.  进入对应的jar包路径下,`java -jar 打包后jar包`即可运行成功

--------------------

5 . 如果端口冲突，可以通过命令去改端口`java -jar jar包名 --server.port=8888`

java -jar xxx.jar --server.port=8888     //等价于在配置文件中设置属性server.port=8888
