我需要用我的应用程序制作一个可执行的jar包。
这是我的pom.xml:

我使用以下内容构建软件包:mvn clean package -DskipTests=true
并通过java -jar
运行它,我得到了:

那我应该怎样改变包装才能最终运行呢?
答案 0 :(得分:3)
spring-boot-maven-plugin
默认情况下创建可执行jar。因此,您不必手动创建它。
基本上,只需将其放在pom.xml
中即可:
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>2.1.2.RELEASE</version>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
如果您的用法需要一些自定义配置(例如设置主类),here您可以找到好的文档。
