簡單切面
@Aspect
@Component
public class TaskLoggerAspect {
	
	private static Logger logger = LoggerFactory.getLogger(TaskLoggerAspect.class);
							
	@Before(value="@annotation(com.minstone.platform.tool.sys.annotation.TaskLoggerAnnotation)")
	public void beforeTask(JoinPoint joinPoint){
		logger.info("標籤執行前");
	}
	
	@After(value="@annotation(com.minstone.platform.tool.sys.annotation.TaskLoggerAnnotation)")
	public void afterTask(JoinPoint joinPoint){
		logger.info("標籤執行後");
	}
	
	@AfterThrowing(value="@annotation(com.minstone.platform.tool.sys.annotation.TaskLoggerAnnotation)")
	public void AfterThrowing(JoinPoint joinPoint){
		logger.info("標籤報錯後");
	}
}
簡單註解
@Target(value={ElementType.METHOD})
public @interface TaskLoggerAnnotation {

}
