写切面类

package com.mycompany.financial.nirvana.core.aspect;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

import java.util.Arrays;

/**

@Aspect
@Component

    private static final Logger logger = LoggerFactory.getLogger(MapperAspect.class);

    @AfterReturning("execution(* com.mycompany.financial.nirvana..*Mapper.*(..))")

        logger.info("Completed: " + joinPoint);
    }


    /**

     */
    @Around("pointCutMethod()")
