Unable to complete the scan for annotations for web application [/wrs] due to a StackOverflowError. Possible root causes include a too low setting for -Xss and illegal cyclic inheritance dependencies.

问题分析：Caused by: java.lang.IllegalStateException: Unable to complete the scan for annotations for web application [/wrs] due to a StackOverflowErro：报错为Java虚拟机栈溢出问题；而导致栈溢出的根本原因是由于包含（ASN1EncodableVector）jar包冲突，这种情况是有两个jar都含有上述相同的类名，且继承关系刚好相反，故造成tomcat启动的环问题。

在项目中搜含有 ASN1EncodableVector 的jar包 只留一个 再重新启动项目试试
