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;
}
