tomcat部署war包出错
错误1
错误日志如下：
Caused by: java.lang.IllegalStateException: Unable to complete the scan for annotations for web application [/capitalplan] 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]

修改conf/catalina.properties:
tomcat.util.scan.DefaultJarScanner.jarsToSkip=\,*设置不扫描jar包
错误2
在运行日志里查看不到错误，可以在logs目录下查看localhost.xxx文件，发现报错如下：
java.lang.NoSuchMethodError: org.springframework.aop.framework.AopProxyUtils.getSingletonTarget(Ljava/lang/Object;)Ljava/lang/Object;这种错误通常由jar包冲突导致，可以在项目里执行mvn dependency:tree查看项目的依赖情况，在上述的日志中，发现是springframework.aop这个出错，直接查找aop关键字，查看依赖后发现有两个jar包依赖于spring-aop，分别是spring-context.jar:4.3.11.RELEASE依赖于spring-aop.jar:4.3.11.RELEASE;spring-jms.jar:4.3.6.RELEASE依赖于spring-aop.jar:4.3.6.RELEASE，可以明显的看到4.3.6和4.3.11版本冲突了，这里将4.3.6版本修改为4.3.11版本后部署成功。
