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)@Documentedpublic @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 org.springframework.stereotype.Component;import org.springframework.validation.BindingResult;import org.springframework.web.multipart.MultipartFile;import javax.annotation.Resource;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.http.HttpServletRequest;import java.lang.reflect.Method;
