前言
今天来分享一下我昨天的成果，昨天计划复现若依系统的系统日志记载功能，若依的系统日志记载的主要实现使用过自定义注解配合切面类来实现的，这里会把标注@Log的方法在用户调用完后，将方法的一部分信息记录在数据库的指定数据表中。因此我们需要java的spring开发四层结构：domain层、mapper层、service层、controller层。到这里项目就大概完成了，注意的是若依中自定义的工具类。本文的项目代码链接：WomPlus: 结合若依项目对原始工单项目内容进行增强 (gitee.com)，若依项目链接：GitHub - yangzongzhuan/RuoYi-fast: (RuoYi)官方仓库 基于SpringBoot的权限管理系统 易读易懂、界面简洁美观。 核心技术采用Spring、MyBatis、Shiro没有任何其它重度依赖。直接运行即可用
1.系统日志记载开发流程五步走
朋友们可以根据自己的项目来调节数据表结构，domain类、mapper接口以及Mapper.xml、Service接口及其实现类，我这里是根据自己项目需求来编写的。
1.1 根据自己项目创建数据表wo_operate_log
USE `wom_plus`
DROP TABLE IF EXISTS `wo_operate_log`
CREATE TABLE `wo_opertae_log`(
`operate_id` BIGINT(20) NOT NULL AUTO_INCREMENT COMMENT '日志主键',
`title` VARCHAR(50) DEFAULT '' COMMENT '模块标题',
`business_type` INT(2) DEFAULT 0 COMMENT '业务类型（0其它 1新增 2修改 3删除）',
`method` VARCHAR(100) DEFAULT '' COMMENT '方法名称',
`request_method` VARCHAR(10) DEFAULT '' COMMENT '请求方式',
`operator_type` INT(1) DEFAULT 0 COMMENT '操作类别（0其它 1后台用户 2手机端用户）',
`operate_name` VARCHAR(50) DEFAULT '' COMMENT '操作人员',
`operate_url` VARCHAR(255) DEFAULT '' COMMENT '请求URL',
`operate_ip` VARCHAR(128) DEFAULT '' COMMENT '主机地址',
`operate_location` VARCHAR(255) DEFAULT '' COMMENT '操作地点',
`operate_param` VARCHAR(2000) DEFAULT '' COMMENT '请求参数',

`status` INT(1) DEFAULT 0 COMMENT '操作状态（0正常 1异常）',
`error_msg` VARCHAR(2000) DEFAULT ''COMMENT '错误消息',
`operate_time` DATETIME COMMENT '操作时间',
`cost_time` BIGINT(20) DEFAULT 0 COMMENT '消耗时间',
PRIMARY KEY (operate_id),
KEY idx_sys_oper_log_bt (`business_type`),
KEY idx_sys_oper_log_s (`status`),
KEY idx_sys_oper_log_ot (`operate_time`)
)ENGINE=INNODB COMMENT='操作日志记录' DEFAULT CHARSET='utf8';

OperateLog

public interface OperateLogMapper {

Mapper接口及其SQL
1.4 根据自己项目编写IOperateService和OperateServiceImpl
public interface IOperateLogService {
/**
* 新增操作日志
*
* @param :operateLog 操作日志对象
*/
public void insertOperateLog(OperateLog operateLog);
/**
* 查询系统操作日志集合
*
* @param :operateLog 操作日志对象
* @return 操作日志集合
*/
public List<OperateLog> selectOperateLogList(OperateLog operateLog);
/**
* 批量删除系统操作日志
*
* @param ids 需要删除的数据
* @return 结果
*/
public int deleteOperateLogByIds(String ids);
/**
* 查询操作日志详细
*
* @param operateId 操作ID
* @return 操作日志对象
*/
public OperateLog selectOperateLogById(Long operateId);
/**
* 清空操作日志
*/
public void cleanOperateLog();
}
@Service
public class OperateLogServiceImpl implements IOperateLogService {
@Autowired(required = false)
private OperateLogMapper operateLogMapper;
@Override
public void insertOperateLog(OperateLog operateLog) {
operateLogMapper.insertOperateLog(operateLog);
}
@Override
public List<OperateLog> selectOperateLogList(OperateLog operateLog) {
return operateLogMapper.selectOperateLogList(operateLog);
}
@Override
public int deleteOperateLogByIds(String ids) {
return deleteOperateLogByIds(ids);
}
@Override
public OperateLog selectOperateLogById(Long operateId) {
return operateLogMapper.selectOperateLogById(operateId);
}
@Override
public void cleanOperateLog() {
operateLogMapper.cleanOperateLog();
}
}
IoperateService及其实现类
1.5 Controller方法上的@Log
@Log(title = "用户管理", businessType = BusinessType.EXPORT)
@PostMapping("/export")
@ResponseBody
public AjaxResult export(@RequestParam(value = "name", required = false) String username){
List<SysUser> list = userDetailsService.getUserListByUsername(username);
ExcelUtil<SysUser> util = new ExcelUtil<>(SysUser.class);
return util.exportExcel(list, "用户数据");
}
2.自定义系统日志记载注解及其切面实现
java中注解与AOP的结合，方便了广大java程序员对应用的开发，能够对原有方法的增强减少很多代码，原来的我们如果要在每个方法上面进行日志记载，那么需要每个方法都调用日志记载的方法，而现在我们只需要在需要日志加载的方法上面加上@ Log就完美快速简单地解决了上述繁杂问题。
2.1 自定义@Log
/**
* 自定义操作日志记录注解
*
* @author ruoyi
*
*/
@Target({ ElementType.PARAMETER, ElementType.METHOD })//作用于方法和参数上面
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Log
{
/**
* 模块
*/
public String title() default "";
/**
* 功能
*/
public BusinessType businessType() default BusinessType.OTHER;
/**
* 操作人类别
*/
public OperatorType operatorType() default OperatorType.MANAGE;
/**
* 是否保存请求的参数
*/
public boolean isSaveRequestData() default true;
/**
* 是否保存响应的参数
*/
public boolean isSaveResponseData() default true;
/**
* 排除指定的请求参数
*/
public String[] excludeParamNames() default {};
}
@Log
2.2 LogAspect(重点)
该类就是根据动态代理来实现的，在Spring中称之为AOP，面向切面编程，可以很好地实现对软件中已有方法在安全、日志、监控等方面的增强。
@Component
@Aspect
/**
* 操作日志记录处理
*/
public class LogAspect {
private static final Logger log = LoggerFactory.getLogger(LogAspect.class);
/** 排除敏感属性字段 */
public static final String[] EXCLUDE_PROPERTIES = { "password", "oldPassword", "newPassword", "confirmPassword" };
/** 计算操作消耗时间 */
private static final ThreadLocal<Long> TIME_THREADLOCAL = new NamedThreadLocal<Long>("Cost Time");
/**
* 处理请求前执行
*/
@Before(value = "@annotation(controllerLog)")
//该方法传入一个注解类型参数，改参数被@Before注解中的@annotation作用，
// 表示只要该注解作用在哪个方法上，就在该方法上生效
public void before(JoinPoint joinPoint, Log controllerLog){
TIME_THREADLOCAL.set(System.currentTimeMillis());

LogAspect
上述代码中的前置通知@Before和后置通知@After是用来记录标注有@Log注解的方法运行所花费的时间，环绕返回注解@AroundReturning是返回系统日志记载信息，环绕异常注解@AroundThrowing是返回这部分代码出现异常是返回的异常信息。主要的日志系统信息实现是在handleLog()方法中，根据切点获取方法名称、请求参数、等等信息。
2.3 若依中的自定义工具类
3.项目运行结果
第一张图的运行结果是使用@Log注解标注在以Excel形式导出数据的export()方法上面，第二张图片是系统日志记载表wo_operate_log记载的执行标有@Log注解的方法的日志记载信息。我这里只截取了后面的内容。
