您好,我是 Spring AOP 的新手。我写了这样的东西:
我的注释:
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface ExceptionHandling {
String onSuccess();
String onFailture();
}
方面类:
@Aspect
public class ExceptionHandler implements Serializable {
@Pointcut(value="execution(public * *(..))")
public void anyPublicMethod() {
}
@Around("anyPublicMethod() && @annotation(exceptionHandling)")
public Object displayMessage(ProceedingJoinPoint joinPoint,ExceptionHandling exceptionHandling) throws FileNotFoundException {
try{
Object point = joinPoint.proceed();
new PrintWriter(new File("D:\\log.txt")).append("FUUCK").flush();
FacesMessageProvider.showInfoMessage(
FacesContext.getCurrentInstance(),exceptionHandling.onSuccess());
return point;
} catch(Throwable t) {
new PrintWriter(new File("D:\\log.txt")).append("FUUCK").flush();
FacesMessageProvider.showFatalMessage(
FacesContext.getCurrentInstance(),
exceptionHandling.onFailture());
return null;
}
}
}
来自 ManagedBean 的方法
@ExceptionHandling(onSuccess=IMessages.USER_UPDATED,onFailture=IMessages.WRONG_DATA)
public void onClickUpdateFromSession(){
onClickUpdate(sessionManager.getAuthenticatedUserBean());
}
和 app-config.xml

我正在尝试使用 Spring AOP 和 JSF 消息制作异常处理程序,但它不会触发建议。请帮我。
