原因：

jar包冲突或者是依赖冲突
因为在struts2的core包中有3.11.0.GA 提出掉即可。

解决方法：

        <!-- struts2-core --><dependency><groupId>org.apache.struts</groupId><artifactId>struts2-core</artifactId><exclusions><exclusion><groupId>javassist</groupId><artifactId>javassist</artifactId></exclusion></exclusions><version>2.3.16.1</version></dependency><!-- javassist --><dependency><groupId>org.javassist</groupId><artifactId>javassist</artifactId><version>3.18.1-GA</version></dependency>
