spring+mybatis基于 AOP实现业务日志管理
最近在项目上用到了操作日志的相关,之前的解决方案就是自己写一个日志project,然后统一调用日志接口即可,这样方便自定义定制,因为有很多设备控制之类的都是需要确认一下的,但是,对数据的操作,比如,增删改查还用这个,就有点多余了,感觉太麻烦了,所以,想想有没有日志管理这样的框架可以调用,然后就想到了spring的AOP。
整个项目的结构如下
第一步,定义日志类
package com.unisits.zngkpt.framework.logframe.pojo; import org.springframework.stereotype.Component; @Component public class LogOperation extends LogOperationKey { private String operatorId; private String comment; private String operatorResult; private Integer transTag; public String getOperatorId() { return operatorId; } public void setOperatorId(String operatorId) { this.operatorId = operatorId; } public String getComment() { return comment; } public void setComment(String comment) { this.comment = comment; } public String getOperatorResult() { return operatorResult; } public void setOperatorResult(String operatorResult) { this.operatorResult = operatorResult; } public Integer getTransTag() { return transTag; } public void setTransTag(Integer transTag) { this.transTag = transTag; } }
因为用mybatis的generate来生成model,所以,这里上面的操作类继承了其主键类,
package com.unisits.zngkpt.framework.logframe.pojo; import org.springframework.stereotype.Component; import java.util.Date; @Component public class LogOperationKey { private Integer unitId; private Integer deviceId; private Integer deviceType; private Date endTime; public Integer getUnitId() { return unitId; } public void setUnitId(Integer unitId) { this.unitId = unitId; } public Integer getDeviceId() { return deviceId; } public void setDeviceId(Integer deviceId) { this.deviceId = deviceId; } public Integer getDeviceType() { return deviceType; } public void setDeviceType(Integer deviceType) { this.deviceType = deviceType; } public Date getEndTime() { return endTime; } public void setEndTime(Date endTime) { this.endTime = endTime; } }
第二步,定义日志的DAO和日志的Service
package com.unisits.zngkpt.framework.logframe.mapper; import com.unisits.zngkpt.framework.logframe.pojo.LogOperation; import org.springframework.stereotype.Repository; /** * @author:lyy * @Date: 2017/6/25 10:33 * @version: * @Description: */ @Repository("logOperationDao") //@Component public interface LogOperationDao { /** * @author: lyy * @Time: 2017/6/25 10:35 * @Descrption: 插入操作类信息 * @param logOperation * @return * @throws */ public int insertLogOperation(LogOperation logOperation); }
<?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.unisits.zngkpt.framework.logframe.mapper.LogOperationDao" > <resultMap id="BaseResultMap" type="com.unisits.zngkpt.framework.logframe.pojo.LogOperation" > <id column="unit_id" property="unitId" jdbcType="INTEGER" /> <id column="device_id" property="deviceId" jdbcType="INTEGER" /> <id column="device_type" property="deviceType" jdbcType="INTEGER" /> <id column="end_time" property="endTime" jdbcType="TIMESTAMP" /> <result column="operator_id" property="operatorId" jdbcType="VARCHAR" /> <result column="comment" property="comment" jdbcType="VARCHAR" /> <result column="operator_result" property="operatorResult" jdbcType="VARCHAR" /> <result column="trans_tag" property="transTag" jdbcType="INTEGER" /> </resultMap> <sql id="Base_Column_List" > unit_id, device_id, device_type, end_time, operator_id, comment, operator_result, trans_tag </sql> <insert id="insertLogOperation" parameterType="com.unisits.zngkpt.framework.logframe.pojo.LogOperation" > insert into log_operation (unit_id, device_id, device_type, end_time, operator_id, comment, operator_result, trans_tag) values (#{unitId,jdbcType=INTEGER}, #{deviceId,jdbcType=INTEGER}, #{deviceType,jdbcType=INTEGER}, #{endTime,jdbcType=TIMESTAMP}, #{operatorId,jdbcType=VARCHAR}, #{comment,jdbcType=VARCHAR}, #{operatorResult,jdbcType=VARCHAR}, #{transTag,jdbcType=INTEGER}) </insert> </mapper>
package com.unisits.zngkpt.framework.logframe.service; import com.unisits.zngkpt.framework.logframe.pojo.LogOperation; /** * @author:lyy * @Date: 2017/6/25 12:03 * @version: * @Description: */ public interface LogOperationService { /** * @author: lyy * @Time: 2017/6/25 12:05 * @Descrption: 插入操作日志 * @param logOperation * @return * @throws */ public void InsertOperateLog(LogOperation logOperation); }
package com.unisits.zngkpt.framework.logframe.service; import com.unisits.zngkpt.framework.logframe.mapper.LogOperationDao; import com.unisits.zngkpt.framework.logframe.pojo.LogOperation; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; /** * @author:lyy * @Date: 2017/6/25 12:03 * @version: * @Description: */ @Service("logOperationService") public class LogOperationServiceImpl implements LogOperationService{ @Autowired LogOperationDao logOperationDao; /** * @param logOperation * @return * @throws * @author: lyy * @Time: 2017/6/25 12:05 * @Descrption: 插入操作日志 */ @Override public void InsertOperateLog(LogOperation logOperation) { logOperationDao.insertLogOperation(logOperation); } }
上面的操作数据库的基本完成了,那么下面就开始真正的切面Aspect了,因为我们要实现注解来实现AOP,所以,先自定义一个注解
第三步,定义一个注解
package com.unisits.zngkpt.framework.logframe.bojo; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; /** * @author:lyy * @Date: 2017/6/25 12:17 * @version: * @Description: */ @Retention(RetentionPolicy.RUNTIME) @Target({ElementType.METHOD}) public @interface OperAnnotation { //模块名 String moduleName(); //操作内容 String option(); }
需要了解更多注解,请点击更多注解
第四步,重头戏来了,真正的Aspect
package com.unisits.zngkpt.framework.logframe.bojo; import com.unisits.zngkpt.framework.logframe.pojo.LogOperation; import com.unisits.zngkpt.framework.logframe.service.LogOperationService; import com.unisits.zngkpt.framework.privilegeframe.bojo.ActiveUser; import org.apache.shiro.SecurityUtils; import org.aspectj.lang.JoinPoint; import org.aspectj.lang.annotation.AfterReturning; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Pointcut; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import org.springframework.web.context.request.RequestAttributes; import org.springframework.web.context.request.RequestContextHolder; import java.text.ParseException; /** * @author:lyy * @Date: 2017/6/25 12:07 * @version: * @Description: */ @Component @Aspect public class LogAspect { @Autowired private LogOperationService logOperationService;//日志记录Service /** * 方法切入点 */ @Pointcut("execution(* com.unisits.zngkpt.common.*.controller.InforeleaseController.*(..))") public void pointerCutMethod() { } /** * 后置通知 * * @param jp * 连接点 * @param annotation * 返回值 */ @AfterReturning(value = "pointerCutMethod() && @annotation(annotation)") public void doAfter(JoinPoint jp, OperAnnotation annotation) throws ParseException{ // System.out.print(jp.getTarget().getClass() + "对象上被"); // System.out.print(jp.getSignature().getName() + "方法删除了"); //在这里可以区分不同的操作,比如登录,退出,普通操作等等 LogOperation log = new LogOperation(); //通过注解获取当前属于那个模块 log.setComment(annotation.moduleName()+":"+annotation.option()); //获取操作时间 log.setEndTime(DateUtils.getCurrentDate()); RequestAttributes ra = RequestContextHolder.getRequestAttributes(); if (ra != null) { ActiveUser activeUser = (ActiveUser) SecurityUtils.getSubject().getPrincipals().getPrimaryPrincipal(); if (activeUser != null) { log.setOperatorId(activeUser.getUserId()); log.setUnitId(Integer.valueOf(activeUser.getUnitId())); log.setDeviceId(1); log.setDeviceType(503); } } try { Object object = jp.getTarget(); if (object != null) { log.setOperatorResult("成功"); } logOperationService.InsertOperateLog(log); } catch (Throwable e) { log.setOperatorResult("失败:" + e.getMessage()); logOperationService.InsertOperateLog(log); } } }
我这里使用了一个时间格式类,如下
package com.unisits.zngkpt.framework.logframe.bojo; import org.apache.commons.lang3.StringUtils; import org.springframework.stereotype.Component; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Calendar; import java.util.Date; /** * @author:lyy * @Date: 2017/6/25 10:42 * @version: * @Description: */ @Component public class DateUtils { private static String defaultDatePattern = "yyyy-MM-dd HH:mm:ss.SSS"; /** * 获得默认的 date pattern */ public static String getDatePattern() { return defaultDatePattern; } /** * 返回预设Format的当前日期字符串 */ public static String getToday() { Date today = new Date(); return format(today); } /** * 使用预设Format格式化Date成字符串 */ public static String format(Date date) { return date == null ? " " : format(date, getDatePattern()); } /** * 使用参数Format格式化Date成字符串 */ public static String format(Date date, String pattern) { return date == null ? " " : new SimpleDateFormat(pattern).format(date); } /** * 使用预设格式将字符串转为Date */ public static Date parse(String strDate) throws ParseException { return StringUtils.isBlank(strDate) ? null : parse(strDate, getDatePattern()); } /** * 使用参数Format将字符串转为Date */ public static Date parse(String strDate, String pattern) throws ParseException { return StringUtils.isBlank(strDate) ? null : new SimpleDateFormat( pattern).parse(strDate); } /** * 在日期上增加数个整月 */ public static Date addMonth(Date date, int n) { Calendar cal = Calendar.getInstance(); cal.setTime(date); cal.add(Calendar.MONTH, n); return cal.getTime(); } public static String getLastDayOfMonth(String year, String month) { Calendar cal = Calendar.getInstance(); // 年 cal.set(Calendar.YEAR, Integer.parseInt(year)); // 月,因为Calendar里的月是从0开始,所以要-1 // cal.set(Calendar.MONTH, Integer.parseInt(month) - 1); // 日,设为一号 cal.set(Calendar.DATE, 1); // 月份加一,得到下个月的一号 cal.add(Calendar.MONTH, 1); // 下一个月减一为本月最后一天 cal.add(Calendar.DATE, -1); return String.valueOf(cal.get(Calendar.DAY_OF_MONTH));// 获得月末是几号 } public static Date getDate(String year, String month, String day) throws ParseException { String result = year + "- " + (month.length() == 1 ? ("0 " + month) : month) + "- " + (day.length() == 1 ? ("0 " + day) : day); return parse(result); } public static Date getCurrentDate() throws ParseException{ String strNow = new SimpleDateFormat(getDatePattern()).format(new Date()); return new SimpleDateFormat(getDatePattern()).parse(strNow); } }
完成了,那么怎么告知spring容器我们有这个呢?那就是开启注解,该配置必须写在springmvc的配置文件,由于我们现在的方法切入点是在controller层,如果你定义在spring的配置文件里面,不会起作用。这牵扯到父子容器的问题。spring默认的主配置文件为父容器,springmvc为子容器,子容器可以使用父容器里面的配置信息,但是父容器却无法使用子容器的配置信息。
<!-- 加入Aspectj配置 -->
<aop:aspectj-autoproxy proxy-target-class="true"/>
好的,现在注解就开启了,那么怎么在控制器里调用呢?
如下
@OperAnnotation(moduleName = "情报板页面",option = "打开") @RequestMapping("/infoman") public String QueryInfoRelease(){ return CommonLib.INFORELEASE_URL_DIR+"inforelease"; }
好的,这里基于注解开发的完成了。
更所详细的如下:
1,自定义注解
3,本日志源码和jar包(因为这里有ActiveUser,自定义的类,主要用于shiro认证框架时保存的参数)
