在用户的一般使用的时候,对于很多操作类型的接口,为了后面便于追查问题,需要记录用户的请求日志。
用户的请求日志目前主流的存储方式有:
- 日志文件
- 数据库
- MongoDB
- ElasticSearch
在商城的项目中暂时存放在MySQL中了。
增加注解
增加专门的注解标识哪些是需要记录用户日志的。
注解就叫BizLog注解:- @Target(ElementType.METHOD)
- @Retention(RetentionPolicy.RUNTIME)
- public @interface BizLog {
- String value() default "";
- }
复制代码 其中的value参数,用来接收用户自定义的日志描述。
后面只要有接口打上了这个注解,就会自动将用户的业务请求日志记录到数据库中。
增加业务日志表
为了方便后续追溯用户的请求行为,将用户的业务请求日志记录到数据库的某一张表中。
这样以后就可以通过这张表查询数据了。- CREATE TABLE `biz_log` (
- `id` bigint NOT NULL AUTO_INCREMENT COMMENT 'ID',
- `method_name` varchar(30) NOT NULL COMMENT '方法名称',
- `description` varchar(30) NOT NULL COMMENT '描述',
- `request_ip` varchar(15) NOT NULL COMMENT '请求ip',
- `browser` varchar(200) NULL COMMENT '浏览器',
- `url` varchar(100) NOT NULL COMMENT '请求地址',
- `param` varchar(300) NULL COMMENT '请求参数',
- `time` int NOT NULL COMMENT '耗时,毫秒级',
- `exception` varchar(300) NULL COMMENT '异常',
- `status` tinyint(1) NOT NULL DEFAULT 1 COMMENT '状态 1:成功 0:失败',
- `create_user_id` bigint NOT NULL COMMENT '创建人ID',
- `create_user_name` varchar(30) NOT NULL COMMENT '创建人名称',
- `create_time` datetime(3) DEFAULT NULL COMMENT '创建日期',
- `update_user_id` bigint DEFAULT NULL COMMENT '修改人ID',
- `update_user_name` varchar(30) DEFAULT NULL COMMENT '修改人名称',
- `update_time` datetime(3) DEFAULT NULL COMMENT '修改时间',
- `is_del` tinyint(1) DEFAULT '0' COMMENT '是否删除 1:已删除 0:未删除',
- PRIMARY KEY (`id`) USING BTREE
- ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COMMENT='业务日志表';
复制代码 增加业务日志拦截器

复制代码 这个拦截器会记录用户业务请求的ip、地址、参数、浏览器和接口耗时都数据。
如果用户业务请求失败了,也会记录一条失败的数据。

复制代码 BizLogService- public interface BizLogService {

复制代码 BizLogServiceImpl- @Service
- public class BizLogServiceImpl implements BizLogService {
- @Autowired
- private BizLogMapper bizLogMapper;
- @Override
- public void save(BizLogEntity bizLogEntity) {
- FillUserUtil.fillCreateUserInfo(bizLogEntity);
