SpringBoot+Swing打包报错：exception is java.awt.HeadlessException

    SpringBoot和Swing一起开发时，在eclipse中运行正常，没有报错， 但是在打包的时候就报错了

Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.xxx.gui.MainFrame]: Constructor threw exception; nested exception is java.awt.HeadlessException

（如果在eclipse中运行报错，则在启动类中加上System.setProperty("java.awt.headless", "false");） 

最后发现是打包时，执行了maven test，打包跳过测试就好了，打包就不会报错

方法1：

mvn install -DskipTests

mvn install -Dmaven.test.skip=true

方法2：

pom.xml中加上

<build>

<plugins>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-surefire-plugin</artifactId>

<version>2.21.0</version>

<configuration>

<skipTests>true</skipTests>

</configuration>

</plugin>

</plugins>

</build>
