Interceptors provide an excellent means to wrap before/after processing. The concept reduces code duplication (think AOP).

Order of interceptors…








Note that some interceptors will interrupt the stack/chain/flow… so the order is very important.

Iterceptors implementing com.opensymphony.xwork.interceptor.PreResultListener will run after the Action executes its action method but before the Result executes

thisWillRunFirstInterceptor
thisWillRunNextInterceptor
followedByThisInterceptor
thisWillRunLastInterceptor
MyAction1
MyAction2 (chain)
MyPreResultListener
MyResult (result)
thisWillRunLastInterceptor
followedByThisInterceptor
thisWillRunNextInterceptor
