note The full stack trace of the root cause is available in the Apache Tomcat/7.0.26 logs.

Apache Tomcat/7.0.26

原因：

struts2.3.1.1 allows ognl3.0.2.jar + ognl3.0.2-source.jar + ognl3.0.1 at the same time . struts2.3.1.2 can only have ognl3.0.4, but remove other versions

ognl3.0.4 is a must and can be the only ognl jar!

经过检测，发现lib中的ognl的版本是ognl-3.0.jar,然后我换成ognl3.0.4.jar，问题得到解决。
