非 root 用戶跑 tomcat 時遇到報錯：

Caused by: java.lang.IllegalStateException: 由于StackOverflower錯誤，無法完成對web應用程序[]的批注的掃描。可能的根本原因包括-Xss的設置過低和非法的循環繼承依賴項。正在處理的類層次結構是[org.bouncycastle.asn1.ASN1OutputStream->org.bouncycastle.asn1.DEROutputStream->org.bouncycastle.asn1.ASN1OutputStream]

解決辦法：
在 tomcat 的 conf/ catalina.properties 文件中排除對上述jar包的掃描，即：在 conf/ catalina.properties 文件中tomcat.util.scan.StandardJarScanFilter.jarsToSkip 末尾增加：

bcpkix-*.jar,bcprov-*.jar,fr-*.jar

如果感覺 tomcat 啟動慢，那是因為要掃描jar里的servlet3.0注解，可以在conf/ catalina.properties文件中tomcat.util.scan.StandardJarScanFilter.jarsToSkip末尾增加不需要掃描的jar來提速，如：

spring-amqp-*.jar,\

spring-aop-*.jar,\

spring-aspects-*.jar,\

spring-beans-*.jar,\
