Spring Boot创建可执行jar包的实例教程
传统的spring项目，可能大部分都要部署到web容器中，如Tomcat。SpringBoot提供了一种超级简单的部署方式，就是直接将应用打成jar包，在生产上只需要执行java-jar就可以运行了。
本篇文章就介绍如何创建可执行jar包，以及如何部署、运行和停止。
第一步，我们需要在pom.xml添加spring-boot-maven-plugin，添加在dependecies部分下面：
org.springframework.boot spring-boot-maven-plugin
第二步，保存pom.xml并运行mvnpackage命令打包：
localhost:spring-boot-tutorial-executablemajunwei$mvnpackage-Dmaven.test.skip=true [INFO]Scanningforprojects... [WARNING] [WARNING]Someproblemswereencounteredwhilebuildingtheeffectivemodelforcom.majunwei:spring-boot-tutorial-executable:jar:0.0.1-SNAPSHOT [WARNING]'parent.relativePath'ofPOMcom.majunwei:spring-boot-tutorial-executable:0.0.1-SNAPSHOT(/Users/majunwei/Documents/work/spring-boot-tutorial/spring-boot-tutorial-executable/pom.xml)pointsatcom.majunwei:spring-boot-tutorialinsteadoforg.springframework.boot:spring-boot-starter-parent,pleaseverifyyourprojectstructure@line6,column10 [WARNING] [WARNING]Itishighlyrecommendedtofixtheseproblemsbecausetheythreatenthestabilityofyourbuild.

这样就完成了打包操作，大好的包保存在target目录里。应该在10MB左右。
localhost:targetmajunwei$ls-lh total28232 drwxr-xr-x4majunweistaff136B8411:12classes drwxr-xr-x3majunweistaff102B8411:14generated-sources drwxr-xr-x3majunweistaff102B8411:14maven-archiver drwxr-xr-x3majunweistaff102B8411:14maven-status -rw-r--r--1majunweistaff14M8411:14spring-boot-tutorial-executable-0.0.1-SNAPSHOT.jar -rw-r--r--1majunweistaff3.2K8411:14spring-boot-tutorial-executable-0.0.1-SNAPSHOT.jar.original drwxr-xr-x3majunweistaff102B8411:12test-classes
这个包里包含了依赖的jar包、classes等信息，如果你想仔细查看这个jar包等内容，你可以使用jartvf命令，或解压出来看：
$jartvfspring-boot-tutorial-executable-0.0.1-SNAPSHOT.jar
target目录里还有个非常小的myproject-0.0.1-SNAPSHOT.jar.original文件。这个是SpringBoot打包之前Maven创建的原始jar文件。
第三步，使用java-jar命令，运行应用：
localhost:targetmajunwei$java-jarspring-boot-tutorial-executable-0.0.1-SNAPSHOT.jar

第四步，跟之前一样，想要退出应用，按ctrl-c就可以了。
