我遇到了一个我无法解决的奇怪问题。每当我尝试在CentOS机器上的应用服务器上从jrxml渲染PDF时，我都会收到“java.io.IOException：读取字体数据的问题”。报告是使用Jaspersoft Studio 5.6.0生成的。我怀疑它甚至不是字体相关的，因为在使用没有任何字体的报告时结果是相同的。
在Windows和Ubuntu 12.04上运行正常。

在抛出异常之前在CentOS上调试输出：
ESC[0mESC[32m13:41:21,228 DEBUG [net.sf.jasperreports.extensions.SpringExtensionsRegistry] (default task-28) Found 0 beans for extension type interface net.sf.jasperreports.repo.RepositoryService
ESC[0mESC[32m13:41:21,233 DEBUG [net.sf.jasperreports.extensions.SpringExtensionsRegistry] (default task-28) Found 0 beans for extension type interface net.sf.jasperreports.repo.PersistenceServiceFactory
在Windows机器上，还有两个额外的调试行，这些调试行在CentOS日志中不存在：
15:48:19,180 DEBUG [net.sf.jasperreports.extensions.SpringExtensionsRegistry] (default task-4) Found 7 beans for extension type interface net.sf.jasperreports.engine.fonts.FontFamily

15:48:19,199 DEBUG [net.sf.jasperreports.extensions.SpringExtensionsRegistry] (default task-4) Found 0 beans for extension type interface net.sf.jasperreports.repo.PersistenceServiceFactory
答案 0 :(得分：0)
看起来有人遇到了similar issue with Jenkins。你试过用yum安装字体吗？
yum install dejavu-sans-fonts
在我的一个CentOS盒子上运行它不会引入任何X依赖。
修改：您的问题可能是由文件系统权限问题引起的。 This person reported a very similar issue由Java临时目录的错误权限引起。
