annotation扫描引起的StackOverflowError问题

问题：

部署应用报错如下：

bash 复制代码

Caused by: java.lang.IllegalStateException: Unable to complete the scan for annotations for web application [ecology] due to a StackOverflowError. Possible root causes include a too low setting for -Xss and illegal cyclic inheritance dependencies.

解决办法：

因为bcprov*.jar中的[org.bouncycastle.asn1.ASN1EncodableVector、org.bouncycastle.asn1.DEREncodableVector两个类互为父子关系，所以扫描时造成死循环。在tongweb.properties中增加：

bash 复制代码

tongweb.util.scan.StandardJarScanFilter.jarsToSkip=bcprov*.jar
