重点注意这句话：

Possible root causes include a too low setting for -Xss and illegal cyclic inheritance dependencies.

解决方法

原因：依赖中重复引用bcprov-jdk15on  jar包

方法1：

如果该程序使用maven编译，在pom.xml文件中找到重复的依赖，忽略掉

也可以直接在程序中找的这个jar包删除 

方法2:

修改tomcat配置文件，文件catalina.properties中“tomcat.util.scan.StandardJarScanFilter.jarsToSkip”后添加“bcprov*.jar” ，跳过jar包加载
