Note that I cut with aop service layer is no problem , but I hope to be able to cut into the action this AOP layer , do not know the expression has no problem, thank you
------ Solution ---- ----------------------------------------
unfamiliar with the landlord said those things .
But the vast majority of cases java.lang.NoSuchMethodException this exception is the wrong version of a package . For example a.jar cited B.class (version1), but the landlord 's operating environment is more than a B.class or is there a wrong version of B.class.
------ For reference only - -------------------------------------
Thank you upstairs to answer
but not reported method is to write my own java:
eg : java.lang.NoSuchMethodException: com.bin.action.LoginAction.getTargetSource ()
java.lang.NoSuchMethodException: com.bin.action.LoginAction.getTargetClass ()
I did not write these methods go , this is a bit like aop in the way, but I could not find in the Aspect which seems appropriate method ,
I also tried some of the latest update package into the jar , but it does not work
------ For reference only ----------------- ----------------------
does not solve now , what is the reason , I also encountered the same problem , if the landlord is resolved, hoping to informed solutions should be grateful
