Java wildfly中的无头异常

我正在尝试开发一个应用程序，其中包括我向我的主管显示我的日志，在wildfly应用程序服务器上部署时，我遇到了Headless异常

您的应用程序似乎需要一些Xserver资源：可能您正在生成图像或类似的东西。

也许你应该在headless模式下运行：或者安装一个图形服务器（可能只是libs iirc）。

你必须从命令行使用-Djava.awt.headless=true。

我尝试过从静态块设置headless属性，但仍然得到异常。setProperty（“java.awt.headless”、“true”）；默认情况下，headless在wildfly中为true
