### 哈喽，大家好 最近领导让写个用切面实现日志保存，经过调研和亲测，以完美解决。在这里分享给大家，给有需要的码友直接使用。直接上代码： ###

依赖引入：

<dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-aop</artifactId>
    </dependency>
    复制代码

创建表：

DROP TABLE IF EXISTS `logger_record`;
    CREATE TABLE `logger_record`  (
      `id` varchar(36) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT 'id',
      `description` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '描述',
      `package_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '操作所在的包',
      `class_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '操作的类名',
      `method_name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '操作的方法名',
      `request_params` text CHARACTER SET utf8 COLLATE utf8_general_ci NULL COMMENT '操作方法的参数',
      `response_params` text CHARACTER SET utf8 COLLATE utf8_general_ci NULL COMMENT '操作方法的出参',
      `running_time` bigint NULL DEFAULT NULL COMMENT '运行时间',
      `created_by` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '创建人ID',
      `date_created` datetime NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
      PRIMARY KEY (`id`) USING BTREE
    ) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;
    
    SET FOREIGN_KEY_CHECKS = 1;
    复制代码

对象实体类：

import com.baomidou.mybatisplus.annotation.IdType;
    import com.baomidou.mybatisplus.annotation.TableId;
    import com.baomidou.mybatisplus.annotation.TableName;
    import com.fasterxml.jackson.annotation.JsonFormat;
    import com.**.app.common.util.TimeUtils;
    import lombok.Data;
    import org.springframework.data.annotation.Id;
    
    import java.io.Serializable;
    import java.time.LocalDateTime;
    import java.util.Date;
    
    /**
     * Created by cb on 2022/11/15 10:07
     */
    //@Entity
    @Data
    public class LoggerRecord implements Serializable {
        @Id
        @TableId(value = "id",type = IdType.ID_WORKER_STR)//可不引入注解，UUID生成
        private String id;
        /**
         * 操作方法的描述
         */
        private String description;//实际没用上
        /**
         * 操作所在的包
         */
        private String packageName;
        /**
         * 操作的类名
         */
        private String className;
        /**
         * 操作的方法名
         */
        private String methodName;
        /**
         * 操作方法的参数
         */
        private String requestParams;
        /**
         * 操作方法的出参
         */
        private String responseParams;
        /**
         * 运行时间
         */
        private Long runningTime;
        /** 创建时间 */
        @JsonFormat(pattern = TimeUtils.PATTERN2)
        private LocalDateTime dateCreated;//可以用date
    
        /** 创建人ID */
        private String createdBy;//实际没用上
    
    }
    复制代码

注解方法：

package com.**.app.server.annotation;
    
    import java.lang.annotation.*;
    
    /**
     * Created by cb on 2022/11/15 10:05
     * 日志描述的注解
     */
    @Documented
    @Retention(RetentionPolicy.RUNTIME)
    @Target(ElementType.METHOD)
    public @interface LoggerManager {
    }
    复制代码

service方法，可根据自己项目去相应改动：

/**
     * 日志增删改的接口
     * Created by cb on 2022/11/15 10:11
     */
    @Service
    public class LoggerRecordRepository extends ServiceImpl<LoggerRecordMapper, LoggerRecord> {
    }
    复制代码

工具类：

         * @param joinPoint
         * @return
         */
        public static Method getMethod(JoinPoint joinPoint){
            MethodSignature signature = (MethodSignature) joinPoint.getSignature();
            Method method = signature.getMethod();
            return method;
        }
    
        /**
         //     * 将参数数组转化为字符串
         //     * @param params  参数数组
         //     * @return 参数字符串
         //     */
        public static String getStringOfParams(Object[] params) {
            if (params.length <= 0 || params.length > 1024 || null == params) {
                return "";
            }
    
            StringBuffer paramString = new StringBuffer("参数:   ");
            for (Object param : params) {
                //将参数转换成字符串
                String s = ToStringBuilder.reflectionToString(param);
                paramString.append(s).append("||");
            }
            return paramString.toString();
        }
    
        /**
         * 转换request 请求参数
         * @param paramMap request获取的参数数组
         */
        public static Map<String, String> converMap(Map<String, String[]> paramMap) {
            Map<String, String> rtnMap = new HashMap<String, String>();
            for (String key : paramMap.keySet()) {
                rtnMap.put(key, paramMap.get(key)[0]);
            }
            return rtnMap;
        }
    
    }

        @Around("AroundPointCut()")
        public Object around(ProceedingJoinPoint point) throws Throwable {
    
            long beginTime = System.currentTimeMillis();
            Object result = point.proceed();
            long time = System.currentTimeMillis() - beginTime;
            try {
                LoggerRecord loggerRecord = saveLog(point, time);
                loggerRecord.setResponseParams(JSON.toJSONString(result));
                loggerRecordRepository.save(loggerRecord);
            } catch (Exception e) {
            }finally {
    
                return result;
            }
    
        }
    
    
        /**
         * 保存日志
         * @param joinPoint

         */
        private LoggerRecord saveLog(ProceedingJoinPoint joinPoint, long time) {
            // 获取RequestAttributes
            RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
            // 从获取RequestAttributes中获取HttpServletRequest的信息
            HttpServletRequest request = (HttpServletRequest) requestAttributes.resolveReference(RequestAttributes.REFERENCE_REQUEST);
    
            //获取该切点处的方法
            Method method = AopUtil.getMethod(joinPoint);
            LoggerRecord loggerRecord = new LoggerRecord();
            //获取切点处的注解
            LoggerManager loggerManager = method.getAnnotation(LoggerManager.class);
            if (null == loggerManager) {
                return loggerRecord;
            }
            //获取请求的描述
    //        String description = loggerManager.
            //获取请求包名
            Signature signature = joinPoint.getSignature();
            //获取请求的类名
            String className = joinPoint.getTarget().getClass().getName();
            //获取请求的方法名
            String methodName = method.getName();
            //获取请求的参数
            Map<String, String[]> parameterMap = request.getParameterMap();
            Map<String, String> stringStringMap = AopUtil.converMap(parameterMap);
    
            log.info("执行===" + methodName + "===开始");
            //打印方法名
            log.info("方法名：" + signature.toString());
            //打印方法参数
            log.info("方法参数：" + JSON.toJSONString(stringStringMap));
            log.info("执行===" + methodName + "===结束");
            //将日志保存
    //        loggerRecord.setDescription(description);
            loggerRecord.setPackageName(signature.toString());
            loggerRecord.setClassName(className);
            loggerRecord.setMethodName(methodName);
            loggerRecord.setRunningTime(time);
            loggerRecord.setRequestParams(JSON.toJSONString(stringStringMap));
            return loggerRecord;
    
        }
    }
    复制代码

最后只需要在自己的接口上加注解@LoggerManager就可以实现此方法的入参出参日志保存

/**
     * 测试
     */
    @GetMapping("/test")
    @ResponseBody
    @LoggerManager
    public ResponseResult test(@RequestParam("userName") String userName) throws BusinessException {
        Map<String, Object> verifyCodeMap = VerifyCodeUtils.verifyCode();
        redisUtils.set(VERIFY_CODE + userName, verifyCodeMap, 60);
        return new ResponseResult(verifyCodeMap);
    }
    
    保存数据库后的图片：

    复制代码

注：所有‘\*\*’的地方为自己项目的包名。 好了，下期会改版此日志保存方法，在数据库配置接口名称 就可以实现日志的打印保存。有好的方法也可一起交流，如果有用 给作者点个赞，持续追踪可点个关注 谢谢大家
