Spring Boot创建可执行jar包的实例教程

这篇文章主要介绍了Spring Boot创建可执行jar包的实例教程，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧

传统的spring项目，可能大部分都要部署到web容器中，如Tomcat。Spring Boot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：

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

第二步，保存pom.xml并运行mvn package命令打包：

localhost:spring-boot-tutorial-executable majunwei$ mvn package -Dmaven.test.skip=true
[INFO] Scanning for projects...
[WARNING] 
[WARNING] Some problems were encountered while building the effective model for com.majunwei:spring-boot-tutorial-executable:jar:0.0.1-SNAPSHOT
[WARNING] 'parent.relativePath' of POM com.majunwei:spring-boot-tutorial-executable:0.0.1-SNAPSHOT (/Users/majunwei/Documents/work/spring-boot-tutorial/spring-boot-tutorial-executable/pom.xml) points at com.majunwei:spring-boot-tutorial instead of org.springframework.boot:spring-boot-starter-parent, please verify your project structure @ line 6, column 10
[WARNING] 
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
[WARNING] 
[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.
[WARNING]

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:target majunwei$ ls -lh
total 28232
drwxr-xr-x 4 majunwei staff  136B 8 4 11:12 classes
drwxr-xr-x 3 majunwei staff  102B 8 4 11:14 generated-sources
drwxr-xr-x 3 majunwei staff  102B 8 4 11:14 maven-archiver
drwxr-xr-x 3 majunwei staff  102B 8 4 11:14 maven-status
-rw-r--r-- 1 majunwei staff  14M 8 4 11:14 spring-boot-tutorial-executable-0.0.1-SNAPSHOT.jar
-rw-r--r-- 1 majunwei staff  3.2K 8 4 11:14 spring-boot-tutorial-executable-0.0.1-SNAPSHOT.jar.original
drwxr-xr-x 3 majunwei staff  102B 8 4 11:12 test-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jar tvf命令，或解压出来看：

$ jar tvf spring-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Spring Boot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:target majunwei$ java -jar spring-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。
