原因及解決方法：
- 檢查tomcat啓動參數設置，日誌有提到一個Xss的配置，在tomcat/bin/Catalina.sh（Linux） | Catalina.bat（Windows）文件中，有可能是配置的啓動內存小了
- 因爲tomcat啓動會去掃描jar包，看錯誤信息org.bouncycastle.asn1.ASN1EncodableVector是出在這個類，這個類似出現在bcprov*.jar這個包，所以在tomcat的配置文件中配置tomcat啓動的時候不掃描這個jar。tomcat/conf/catalina.properties文件，在tomcat.util.scan.DefaultJarScanner.jarsToSkip=裏面加上bcprov*.jar過濾
