1 图片生成报错
1: org.awareness.user.commons.image.utils.ImageUtils 2: 有图片自动生成器，windows上正常,linux上就报以上错误 3: 4: java.lang.InternalError: 5: Can't connect to X11 window server using 'localhost:11.0' as the value of the DISPLAY variable. 6: at sun.awt.X11GraphicsEnvironment.initDisplay(Native Method) 7: at sun.awt.X11GraphicsEnvironment.<clinit>(X11GraphicsEnvironment.java:134) 8: at java.lang.Class.forName0(Native Method) 9: at java.lang.Class.forName(Class.java:141)
原因是windows内核集成了gui，而linux上没有启动x server
1.1 解决办法：
- 启动x server
- 在java运行参数上加-Djava.awt.headless=true
修改${TOMCATHOME}/bin/catalina.sh
在org.apache.catalina.startup.Bootstrap "$@" * 部分后面前加上 -Djava.awt.headless=true \ 修改为如下: 共有7处.
