大家好，又见面了，我是你们的朋友全栈君。
java 项目日志管理设计方案
因项目需要记录整个系统的操作记录，考虑到系统操作日志的数据量，单表很容易达到瓶颈，导致查询效率低下，顾使用分表方案，减小数据库的负担，缩短查询时间。目前对于分表的解决方案有很多，本博文主要讲解博主自行实现的日志管理的解决方案，如有遗漏或错误的请各位大佬多多包涵 鉴于总是有人私信要demo，这里将以前搭的一个简易的项目贴出来：https://gitee.com/jiangliuhong/syslog.git
1 创建日志表
1.1 日志表Sql语句如下
具体表设计随项目情况而变化
表创建SQL语句
代码语言：javascript复制CREATE TABLE `sys_user_log` (
`log_id` varchar(32) NOT NULL COMMENT '日志表id，uuid',
`user_id` varchar(32) DEFAULT NULL COMMENT '用户id,记录操作用户',
`module_name` varchar(225) NOT NULL COMMENT '模块名称',
`operate` varchar(225) NOT NULL COMMENT '操作名称',
`time` datetime NOT NULL COMMENT '操作时间',
`class_name` varchar(225) NOT NULL COMMENT '类名称',
`method_name` varchar(225) NOT NULL COMMENT '方法名称',
`params` longtext COMMENT '传入参数',
`ip` varchar(225) NOT NULL COMMENT '操作ip',
PRIMARY KEY (`log_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;1.2 日志表创建
因考虑到项目情况，顾为每月创建一个日志表
1.2.1 表创建方法
创建service、dao方法
DbMapper.xml
代码语言：javascript复制<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.carfi.vrcp.dao.SysDbMapper">
<update id="createUserLogTable" parameterType="java.lang.String">
create table #{name,jdbcType=VARCHAR} like sys_user_log
</update>
</mapper>DbMapper.java
代码语言：javascript复制public interface SysDbMapper {
/**
* 创建数据表
* @param name 表名
*/
void createUserLogTable(String name);
}DbService.java
代码语言：javascript复制public interface SysDbService {
/**
* 创建数据表
*
* @param preName 名称前缀
* @param isSufTime 是否显示 时间后缀
*/
void createTable(String preName, Boolean isSufTime);
}DbServiceImpl.java
代码语言：javascript复制@Service("dbService")
public class DbServiceimpl implements DbService {
@Autowired
private DbMapper dbMapper;
@Override
public void createTable(String preName, Boolean sufTime) {
if (sufTime) {
dbMapper.createTable(preName "_" getSufName());
} else {
dbMapper.createTable(preName);
}
}
/**
* 获取名称后缀<br>
* 格式: 20170301
*
* @return
*/
private String getSufName() {
Date d = new Date();
String s = DateUtil.date2String(d, false);
return s.replace("-", "");
}
}1.2.2 创建定时任务(每月第一天凌晨执行)
BaseQuartz.java
代码语言：javascript复制/**
* 报警定时任务接口
*
*/
public interface BaseQuartz {
/**
* 定时任务执行方法
*/
public void work();
}DbQuartz.java
代码语言：javascript复制public class DbQuartz implements BaseQuartz {
private static final Logger log = LoggerFactory.getLogger(DbQuartz.class);
/**
* 默认表名
*/
private static String tableName = "sys_user_log";
@Override
public void work() {
try {
//创建表
DbService dbService = (SysDbService) SpringUtil.getBean("sysDbService");
dbService.createTable(tableName, true);
log.info("创建表" tableName "成功");
//更新系统用户日志表表缓存
SysCacheUtil.flushSysUserLogTableName();
} catch (Exception e) {
log.error("创建表" tableName "失败");
work();
}
}
}quartz配置文件：spring-quartz.xml
代码语言：javascript复制<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<property name="triggers">
<list>
<ref bean="dbQuartzJobTrigger" />
</list>
</property>
</bean>
</beans> 到止为止日志表自动创建逻辑完成
2 日志表数据插入查询
因考虑查询速度，采用根据传入的时间进行联合查询，规定只能查询连续3个月的日志数据，即前台传入 20170301,20170525 则联合表sys_user_log20170301,sys_user_log20170401,sys_user_log20170501三表进行联合查询。

}2.2 用户日志的记录
用户日志的记录，主要通过自定义java注解，通过在service方法标记注解，使用spring aop进行日志存储
2.2.1 自定义java注解
自定义注解主要包括模块名称、操作内容两个内容，其使用方式为：@LogAnnotation(moduleName = “角色管理”, operate = “新增角色”) 如果需要其他内容，可根据以下源码进行扩展
LogAnnotation.java
代码语言：javascript复制import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
/**
* 自定义日志注解
*/
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD})
@Documented
public @interface LogAnnotation {
/**模块名称*/
String moduleName() default "";
/**操作内容*/
String operate() default "";
}注解使用：
代码语言：javascript复制@LogAnnotation(moduleName = "角色管理", operate = "新增角色")
@Override
public void saveRole(SysRole role, String[] perIds) {2.2.2 切面配置
aop配置
代码语言：javascript复制 <aop:config>

代码语言：javascript复制定义拦截器，重写afterReturning方法，在调用service方法完成之后触发该方法实现日志写入
/**
* 日志拦截器
*
*/
public class LogInterceptor {
/**
* 方法正常完成后执行方法
* @param point
*/
@SuppressWarnings("rawtypes")
public void afterReturning(JoinPoint point) {
try {
Subject subject = null ;
try {
subject = CarfiUserUtil.getSubject();
} catch (Exception e) {
e.printStackTrace();
//发生异常则不进行
return ;
}
SysUserLog userLog = new SysUserLog();
String targetName = point.getTarget().getClass().getName();
Class targetClass = Class.forName(targetName);
String methodName = point.getSignature().getName();
Method[] method = targetClass.getMethods();
Object[] params = point.getArgs(); // 获得参数列表
for (Method m : method) {
if (m.getName().equals(methodName)) {
Class[] tmpCs = m.getParameterTypes();
if (tmpCs.length == params.length) {
// 获取注解内容
LogAnnotation logAnnotation = m.getAnnotation(LogAnnotation.class);
if(logAnnotation != null){
//写入参数
if(params.length>0){
// 使用json转换工具 将参数转为json串，以便存入数据库
String jsonStr = JsonUtil.toJSONStr(params);
userLog.setParams(jsonStr);
}
//获取模块名称
String moduleName = logAnnotation.moduleName();
//获取操作名称
String operate = logAnnotation.operate();
userLog.setModuleName(moduleName);
userLog.setOperate(operate);
userLog.setClassName(targetName);
userLog.setMethodName(methodName);
userLog.setLogId(CommonUtil.generatePrimaryKey());
userLog.setTime(new Date());
HttpServletRequest request = (HttpServletRequest)((WebSubject)subject).getServletRequest();
userLog.setIp(CommonUtil.getIpAddr(request));
userLog.setUserId(CarfiUserUtil.getSysUser().getUserId());
SysUserLogService userLogService = (SysUserLogService) SpringUtil.getBean ("sysUserLogService");
userLogService.addUserLog(userLog);
break;
}
}
}
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
}3 SpringUtil.java 解释
SpringUtil的作用为在非Spring IOC容器下获取Spring IOC容器的上下文环境中的类，比如获取某个bean，最常见的如本文中的多次出现的“SysUserLogService userLogService = (SysUserLogService) SpringUtil.getBean (“sysUserLogService”);”通过SpringUtil得到service
3.1 SpringUtil 配置详解
SpringUtil.java
代码语言：javascript复制import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
/**
* Spring工具类
*/
public class SpringUtil implements ApplicationContextAware {
/** 上下文 */
private static ApplicationContext applicationContext;
public static ApplicationContext getApplicationContext() {
return applicationContext;
}
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
SpringUtil.applicationContext = applicationContext;
}
/**
* 根据Bean ID获取Bean
*
* @param beanId
* @return
*/
public static Object getBean(String beanId) {
if(applicationContext == null){
return null;
}
return applicationContext.getBean(beanId);
}
}spring 配置文件（application.xml）中配置相应的bean,在配置文件中注册的SpringUtil bean 应在spring扫描配置之前
代码语言：javascript复制 <bean id="springUtil" class="XXX.XXXX.SpringUtil"></bean>
<context:component-scan base-package="XXX.XXX.service"></context:component-scan>发布者：全栈程序员栈长，转载请注明出处：https://javaforall.cn/144027.html原文链接：https://javaforall.cn
