Spring AOP implements exception blocking

Using the AOP exception Mount feature, you can uniformly handle the exceptions thrown by the method, and reduce the number of duplicate code, implemented as follows:

1. Realize Throwadvice

1  Public classExceptionhandlerImplementsThrowsadvice {2 3     Private StaticLogger Logger = Loggerfactory.getlogger (Exceptionhandler.class);4 5      Public voidAfterthrowing (Exception e)throwsThrowable {6Logger.debug ("Exception's Coming!" ");7     }8}

2. Configure in the Application.xml file

1     <BeanID= "Exceptionhandler"class= "Com.lz.cgw.api.service.exception.ExceptionHandler" />2 3     <Aop:config>4         <Aop:aspectref= "Exceptionhandler">5             <Aop:pointcutID= "Exceptionservice"expression= "Execution (* com.lz.cgw.api.service.apiuserserviceimpl.* (..))" />6             <aop:after-throwingPointcut-ref= "Exceptionservice"Method= "Afterthrowing"throwing= "E" />7         </Aop:aspect>8     </Aop:config>

Be careful not to miss the throwing configuration, and the parameter name to go to the advice in the first place, or the binding will error.
