使用@Aspect标注一个切面
@Aspect
@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class LogAspect {
@AfterReturning(Logger.class)
public void afterReturning(@Returning Object returnValue) {
log.debug("@AfterReturning returnValue: [{}]", returnValue);
}
@AfterThrowing(Logger.class)
public void afterThrowing(@Throwing Throwable throwable) {
log.error("@AfterThrowing With Msg: [{}]", throwable.getMessage(), throwable);
}
@Before(Logger.class)
public void before(@Annotated Logger logger, @Argument User user) {
log.debug("@Before method in class with logger: [{}] , Argument:[{}]", logger, user);
}
@After(Logger.class)
public Object after(@Returning User returnValue, @Arguments Object[] arguments) {
log.debug("@After method in class");
return returnValue.setSex("女");
}
@Around(Logger.class)
public Object around(@JoinPoint Joinpoint joinpoint) throws Throwable {
log.debug("@Around Before method");
// int i = 1 / 0;
Object proceed = joinpoint.proceed();
log.debug("@Around After method");
return proceed;
}
