tomcat啟動報錯，具體報錯資訊如下：
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]


根據報錯資訊提示，好像是調整-Xss的大小，但這個並不是問題的所在，看後面的錯誤資訊tomcat是在掃描org.jaxen.util.AncestorAxisIterator這個類的時候報錯，所以解決方法有兩個：


一、忽略tomcat啟動時掃描jar包
tomcat8.0:
開啟在tomcat的conf目錄裡面catalina.properties的檔案，
tomcat.util.scan.StandardJarScanFilter.jarsToSkip=\
改為tomcat.util.scan.DefaultJarScanner.jarsToSkip=\,*


tomcat8.5:
開啟在tomcat的conf目錄裡面catalina.properties的檔案，
tomcat.util.scan.StandardJarScanFilter.jarsToSkip=\
改為tomcat.util.scan.StandardJarScanFilter.jarsToSkip=\,*


二、更新jar包
更好的解決方案是更新jar包，更新Jaxen-1.1.6和dom4j-1.6.1兩個jar包
