Package com.atlassian.crowd.xwork.interceptors

Class XWorkTransactionInterceptor

java.lang.Object
com.atlassian.crowd.xwork.interceptors.XWorkTransactionInterceptor
All Implemented Interfaces:
com.opensymphony.xwork2.interceptor.Interceptor, Serializable
Direct Known Subclasses:
CrowdXWorkTransactionInterceptor
public abstract class XWorkTransactionInterceptor extends Object implements com.opensymphony.xwork2.interceptor.Interceptor
Manages two separate database transactions around the action execution and result execution in XWork, using the Spring PlatformTransactionManager.

The first transaction begins as soon as this interceptor executes. It is committed in a PreResultListener which runs just before the result executes. The second transaction is opened in the same listener. The second transaction is committed when control returns to the interceptor after the action and result executions are both complete.

The active transaction will be rolled back if an exception is caught by this interceptor during the execution of either the action or the result.

Implementations should override getTransactionManager() to provide the Spring transaction manager, and shouldIntercept(ActionInvocation) to configure when transactions should be applied to actions.

      invocation - the action being invoked
      Returns:
      true if the action should be wrapped in a transaction
