Java SpringBoot 项目打包

前提条件

　　1、已安装配置好maven

Maven打包命令介绍

　　mvn clean package  依次执行了clean、resources、compile、testResources、testCompile、test、jar(打包)等７个阶段；
　　mvn clean install     依次执行了clean、resources、compile、testResources、testCompile、test、jar(打包)、install等8个阶段；
　　mvn clean deploy    依次执行了clean、resources、compile、testResources、testCompile、test、jar(打包)、install、deploy等９个阶段。

　　由上面的分析可知主要区别如下:

　　　　package命令完成了项目编译、单元测试、打包功能，但没有把打好的可执行jar包（war包或其它形式的包）布署到本地maven仓库和远程maven私服仓库；
　　　　install命令完成了项目编译、单元测试、打包功能，同时把打好的可执行jar包（war包或其它形式的包）布署到本地maven仓库，但没有布署到远程maven私服仓库；
　　　　deploy命令完成了项目编译、单元测试、打包功能，同时把打好的可执行jar包（war包或其它形式的包）布署到本地maven仓库和远程maven私服仓库。　　

第一步，配置mainClass

在pom.xml中增加configruation配置mainClass

 <build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <mainClass>com.vmware.firstappdemo.FirstAppDemoApplication</mainClass>
            </configuration>
        </plugin>
    </plugins>
</build>

第二步，开始打包

shongbing-a01:~ shongbing$ cd Downloads/first-app-demo
shongbing-a01:first-app-demo shongbing$ mvn -Dmaven.test.skip -U clean package

第三步，运行jar包

shongbing-a01:first-app-demo shongbing$ cd target/
shongbing-a01:target shongbing$ java -jar first-app-demo-0.0.1-SNAPSHOT.jar
