网友也碰到了这个错误所以，如下：

从评论中找到了一些答案：

1. 升级tomcat

Hi,
Please update to apache-tomcat-7.0.59

I have involved with it too,updating to tomcat-8.0.33 ,it solved.

所以，将tomcat升级到7.0.59版本以上都可以。

2.修改配置文件

I solve it by adding below to catalina.properties
tomcat.util.scan.DefaultJarScanner.jarsToSkip=javassist-*.jar

3.排除javassist-3.20.0-GA.jar

            <groupId>org.hibernate</groupId>
