如果tomcat启动时出现以下错误，原因是由于 JDK版本不对，程序运行的版本跟系统环境的版本不一致导致
INFO: JSR 356 WebSocket (Java WebSocket 1.0) support is not available when running on Java 6. To suppress this message, run Tomcat on Java 7, remove the WebSocket JARs from $CATALINA_HOME/lib or add the WebSocketJARs to the tomcat.util.scan.DefaultJarScanner.jarsToSkip property in $CATALINA_BASE/conf/catalina.properties. Note that the deprecated Tomcat 7 WebSocket API will be available.

解决处理：版本一致不就得了。。.*&^
