要打包的话，依然是maven，当然要跳过test，否则依然会报错java.awt.headlessException,

idea中跳过测试只需要点一个按钮，如图

就是上排图片倒数第4个

然后在pom中加入如下代码

<build>

      <plugin>

</build>

如果找不到<groupId>com.akathist.maven.plugins.launch4j</groupId> <artifactId>launch4j-maven-plugin</artifactId>，你可以加上

<dependency>
   <groupId>com.akathist.maven.plugins.launch4j</groupId>
   <artifactId>launch4j-maven-plugin</artifactId>
   <version>1.7</version>
</dependency>

丢到依赖里面，重新加载，等加载完了再删了这个依赖。

要改的地方就是两个<mainClass></mainClass>改成你自己的springboot主类，另外加一个0.ico的图片放到<icon>src/main/resources/0.ico</icon>，点package,生成的exe如下图
