最近在使用tomcat 部署应用是遇到异常如下:

Caused by: java.lang.IllegalStateException: Unable to complete the scan for annotations for web application [/xxxx] 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.bouncycastle.asn1.ASN1EncodableVector->org.bouncycastle.asn1.DEREncodableVector->org.bouncycastle.asn1.ASN1EncodableVector]

分析原因:tomcat 启动扫描注解时抛出异常 StackOverflowError,扫描具体类为:

org.bouncycastle.asn1.ASN1EncodableVector->org.bouncycastle.asn1.DEREncodableVector->org.bouncycastle.asn1.ASN1EncodableVector

从以下方面检查错误:

1. 栈内存不足,修改tomcat启动参数,增加栈内存, 如:-Xss100m

2. 在你的应用中告诉tomcat不要扫描annotations, 修改web.xml 如下:

<web-app id="WebApp_ID" version="2.4" metadata-complete="true"
xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">[/code] 
[/code]

3. 限制tomcat扫描jar 文件,参考:http://tomcat.apache.org/tomcat-7.0-doc/config/jar-scanner.html

4. 另外, 你可以创建一个war包,其中在WEB-INF\lib中包含第三方依赖的jar, 当启动tomcat时,如果发现错误信息类似如下:

Unable to complete the scan for annotations for web application [/xxxx] 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.bouncycastle.asn1.ASN1EncodableVector->org.bouncycastle.asn1.DEREncodableVector->org.bouncycastle.asn1.ASN1EncodableVector]


这个可能是第三方api的一个bug.可以到其官网下载最新版本看看是否修复。
