Aspect定义（针对注解）

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.Signature;
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 org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;

@Aspect
@Component
public class LogAspect {

    private static final Logger LOGGER = LoggerFactory.getLogger(LogAspect.class);

    @Pointcut("@annotation(permission)")
    public void annotationPointcut(Permission permission){}

    @Around("annotationPointcut(permission)")
    public Object around(ProceedingJoinPoint pjp, Permission permission) throws Throwable {
        //获取请求方法
        Signature sig = pjp.getSignature();
        String method = pjp.getTarget().getClass().getName() + "." + sig.getName();

        //获取请求的头部
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
        String header = request.getHeader("permissionKey");
        LOGGER.info(header);

        //获取请求的参数
        Object[] args = pjp.getArgs();
        //fastjson转换
        String params = JSONObject.toJSONString(args);

        //打印请求参数
        LOGGER.info("参数:" + method + ":" + params);

        //执行方法
        Object result = pjp.proceed();

        //打印返回结果
        LOGGER.info("返回结果:" + method + ":" + result);
        return result;
    }
}

注解定义

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Permission {
    String value() default "";
}
