Spring 中使用@Aspect方法级切面拦截

1:定义注解类 @Target(ElementType.METHOD) @Retention(RetentionPolicy.RUNTIME) public @interface MethodLogger { }

2.定义切面处理类

@Component @Aspect public class MethodLoggerAspect { @Around("@annotation(com.*.annotation.MethodLogger)") public Object doAround(ProceedingJoinPoint pjp) throws Throwable { Signature signature = pjp.getSignature(); String methodName = signature.getName(); UUID uuid = UUID.randomUUID(); Object[] args = pjp.getArgs(); String info = JSON.toJSONString(args); //方法执行前处理 Object obj = pjp.proceed(); String resultStr = JSON.toJSONString(obj); //方法执行后处理 return obj; } }

 

3.方法使用切面拦截

@MethodLogger public Object myMethod (long userId, String bizCode){ return null; }
