tomcat启动报错，具体报错信息如下：
Unable to complete the scan for annotations for web application [/Ftrans] due to a StackOverflowError. Possible root causes include a too low setting for -Xss and illegal cyclic inheritance dependencies. The class hierarchy being processed was [org.jaxen.util.AncestorAxisIterator->org.jaxen.util.AncestorOrSelfAxisIterator->org.jaxen.util.AncestorAxisIterator]
根据报错信息提示，好像是调整-Xss的大小，但这个并不是问题的所在，看后面的错误信息tomcat是在扫描org.jaxen.util.AncestorAxisIterator这个类的时候报错，所以解决方法有两个：
一、忽略tomcat启动时扫描jar包
tomcat8.0:
打开在tomcat的conf目录里面catalina.properties的文件，
tomcat.util.scan.StandardJarScanFilter.jarsToSkip=\
改为tomcat.util.scan.DefaultJarScanner.jarsToSkip=\,*
tomcat8.5:
打开在tomcat的conf目录里面catalina.properties的文件，
tomcat.util.scan.StandardJarScanFilter.jarsToSkip=\
改为tomcat.util.scan.StandardJarScanFilter.jarsToSkip=\,*
二、更新jar包
更好的解决方案是更新jar包，更新Jaxen-1.1.6和dom4j-1.6.1两个jar包
