SpringBoot 将项目打包成 jar 包

参考：https://www.jianshu.com/p/84883627db67

1.在pom.xml文件中导入Springboot的maven依赖（有的项目自带此代码）

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

2.package一下

双击package，稍等一会

如图所示为构建成功

3.package完成以后,target中会生成一个.jar包

在终端中打开此目录

然后java -jar demo-0.0.1-SNAPSHOT.jar --server.port=8086 即可运行jar包

server.port用于设置端口

PS E:\Projects\Github\java\demo\target> java -jar demo-0.0.1-SNAPSHOT.jar --server.port=8086
