Error initializing endpoint java.io.IOException: Invalid keystore format

最近在研究cas，在服务器上运行：

keytool -genkey -alias tomcat-server -keyalg RSA -keypass changeit -storepass changeit -validity 3600


在/root目录下生成.keystore文件

tomcat配置为：

<Connector protocol="org.apache.coyote.http11.Http11NioProtocol"  
              port="8443" minSpareThreads="5" maxSpareThreads="75"  
              enableLookups="true" disableUploadTimeout="true"    
              acceptCount="100"  maxThreads="200"  
              scheme="https" secure="true" SSLEnabled="true"  
              clientAuth="false" sslProtocol="TLS"  
              keystoreFile="/root/.keystore"    
              keystorePass="changeit"/>

启动tomcat，抛如下异常：

这个异常导致的原因是：生成.keystore证书的jre版本和tomcat所用的jre版本不一样。在/etc/profile下配置一下jdk路径，重新生成证书，问题解决。
