Java之~ Aop自定义注解日志

大纲步骤：
一，创建需要记录的日志表，创建基础方法。（省略）
二，在需要加记录日志的方法上加Aop注解1，创建一个注解类，Aop中定义一个注解

import java.lang.annotation.*;
/*** http 请求第三方请求日志使用注解*/
@Target({ElementType.TYPE,ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface HttpLog {//需要手动指定的枚举类HttpLogTypeEnum type();
}

2，切面处理

import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
import com.alibaba.fastjson.serializer.PropertyFilter;
import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.jeecg.common.constant.CommonConstant;
import org.jeecg.common.util.SpringContextUtils;
import org.springframework.core.LocalVariableTableParameterNameDiscoverer;

import java.lang.reflect.Method;
