前言

最开始蘑菇博客收集用户访问日志,是直接在请求接口里面进行编写的,比如像下面这样

很显然这种方法是非常笨的一种方法,因为它直接侵入了我们的业务代码,引入无关的操作,因此这次主要就是通过spring aop + 自定义接口,来收集用户的访问日志

编写自定义接口

首先我们需要创建一个自定义接口

package com.moxi.mogublog.web.log;

import com.moxi.mougblog.base.enums.EBehavior;
import com.moxi.mougblog.base.enums.PlatformEnum;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/**
 * 日志记录、自定义注解
 *
 * @author 陌溪
 * @date 2020年2月27日08:55:02
 */
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface BussinessLog {

    /**
     * 业务名称
     *
     * @return
     */
    String value() default "";

    /**
     * 用户行为
     *
     * @return
     */
    EBehavior behavior();

    /**
     * 平台,默认为WEB端
     */
    PlatformEnum platform() default PlatformEnum.WEB;

    /**
     * 是否将当前日志记录到数据库中
     */
    boolean save() default true;
}

这里的用户行为使用了枚举类,方便扩展,目前共有15中行为

package com.moxi.mougblog.base.enums;

import com.moxi.mogublog.utils.JsonUtils;
import com.moxi.mougblog.base.global.BaseSysConf;

import java.util.HashMap;
import java.util.Map;

public enum EBehavior {

    BLOG_TAG("点击标签", "blog_tag"),
    BLOG_SORT("点击博客分类", "blog_sort"),
    BLOG_CONTNET("点击博客", "blog_content"),
    BLOG_PRAISE("点赞", "blog_praise"),
    FRIENDSHIP_LINK("点击友情链接", "friendship_link"),
    BLOG_SEARCH("点击搜索", "blog_search"),
    STUDY_VIDEO("点击学习视频", "study_video"),
    VISIT_PAGE("访问页面", "visit_page"),
    VISIT_SORT("点击归档", "visit_sort"),
    BLOG_AUTHOR("点击作者", "blog_author"),
    PUBLISH_COMMENT("发表评论", "publish_comment"),
    DELETE_COMMENT("删除评论", "delete_comment"),
    REPORT_COMMENT("举报评论", "report_comment"),
    VISIT_CLASSIFY("点击分类", "visit_classify");


    private String content;
    private String behavior;

    private EBehavior(String content, String behavior) {
        this.content = content;
        this.behavior = behavior;
    }

    /**
     * 根据value返回枚举类型,主要在switch中使用
     * @param value
     * @return
     */
    public static EBehavior getByValue(String value) {
        for(EBehavior behavior: values()) {
            if(behavior.getBehavior() == value) {
                return behavior;
            }
        }
        return null;
    }

    public static Map<String, String> getModuleAndOtherData(EBehavior behavior, Map<String, Object> nameAndArgsMap, String bussinessName) {
        String otherData = "";
        String moduleUid = "";
        switch (behavior) {
            case BLOG_AUTHOR: {
                // 判断是否是点击作者
                if(nameAndArgsMap.get(BaseSysConf.AUTHOR) != null) {
                    otherData = nameAndArgsMap.get(BaseSysConf.AUTHOR).toString();
                }
            };break;
            case BLOG_SORT: {
                // 判断是否点击博客分类
                if(nameAndArgsMap.get(BaseSysConf.BLOG_SORT_UID) != null) {
                    moduleUid = nameAndArgsMap.get(BaseSysConf.BLOG_SORT_UID).toString();
                }
            };break;
            case BLOG_TAG: {
                // 判断是否点击博客标签
                if(nameAndArgsMap.get(BaseSysConf.TAG_UID) != null) {
                    moduleUid = nameAndArgsMap.get(BaseSysConf.TAG_UID).toString();
                }
            };break;
            case BLOG_SEARCH: {
                // 判断是否进行搜索
                if(nameAndArgsMap.get(BaseSysConf.KEYWORDS) != null) {
                    otherData = nameAndArgsMap.get(BaseSysConf.KEYWORDS).toString();
                }
            };break;
            case VISIT_CLASSIFY: {
                // 判断是否点击分类
                if(nameAndArgsMap.get(BaseSysConf.BLOG_SORT_UID) != null) {
                    moduleUid = nameAndArgsMap.get(BaseSysConf.BLOG_SORT_UID).toString();
                }
            };break;
            case VISIT_SORT: {
                // 判断是否点击归档
                if(nameAndArgsMap.get(BaseSysConf.MONTH_DATE) != null) {
                    otherData = nameAndArgsMap.get(BaseSysConf.MONTH_DATE).toString();
                }
            };break;
            case BLOG_CONTNET: {
                // 判断是否博客详情
                if(nameAndArgsMap.get(BaseSysConf.UID) != null) {
                    moduleUid = nameAndArgsMap.get(BaseSysConf.UID).toString();
                }
            };break;
            case BLOG_PRAISE: {
                // 判断是否给博客点赞
                if(nameAndArgsMap.get(BaseSysConf.UID) != null) {
                    moduleUid = nameAndArgsMap.get(BaseSysConf.UID).toString();
                }
            };break;
            case VISIT_PAGE: {
                // 访问页面
                otherData = bussinessName;
            };break;
            case PUBLISH_COMMENT: {
                Object object = nameAndArgsMap.get(BaseSysConf.COMMENT_VO);
                Map<String, Object> map = JsonUtils.objectToMap(object);
                if(map.get(BaseSysConf.CONTENT) != null) {
                    otherData = map.get(BaseSysConf.CONTENT).toString();
                }
            };break;
            case REPORT_COMMENT: {
                // 举报评论
                Object object = nameAndArgsMap.get(BaseSysConf.COMMENT_VO);
                Map<String, Object> map = JsonUtils.objectToMap(object);
                if(map.get(BaseSysConf.CONTENT) != null) {
                    otherData = map.get(BaseSysConf.CONTENT).toString();
                }
            };break;
            case DELETE_COMMENT: {
                // 删除评论
                Object object = nameAndArgsMap.get(BaseSysConf.COMMENT_VO);
                Map<String, Object> map = JsonUtils.objectToMap(object);
                if(map.get(BaseSysConf.CONTENT) != null) {
                    otherData = map.get(BaseSysConf.CONTENT).toString();
                }
            };break;
        }
        Map<String, String> result = new HashMap<>();
        result.put(BaseSysConf.MODULE_UID, moduleUid);
        result.put(BaseSysConf.OTHER_DATA, otherData);
        return result;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    public String getBehavior() {
        return behavior;
    }

    public void setBehavior(String behavior) {
        this.behavior = behavior;
    }


}

编写AOP代码

在AOP中,我们使用环绕通知的方式,来收集用户的访问日志

package com.moxi.mogublog.web.log;

import com.moxi.mogublog.utils.AopUtils;
import com.moxi.mogublog.utils.AspectUtil;
import com.moxi.mogublog.utils.IpUtils;
import com.moxi.mogublog.web.global.SysConf;
import com.moxi.mogublog.xo.entity.ExceptionLog;
import com.moxi.mogublog.xo.entity.SysLog;
import com.moxi.mogublog.xo.service.WebVisitService;
import com.moxi.mougblog.base.enums.EBehavior;
import com.moxi.mougblog.base.holder.RequestHolder;
import com.moxi.mougblog.base.util.RequestUtil;
import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
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 javax.servlet.http.HttpServletRequest;
import java.lang.reflect.Method;
import java.util.Map;

/**
 * 日志切面
 */
@Aspect
@Component
@Slf4j
public class LoggerAspect {

    private SysLog sysLog;

    private ExceptionLog exceptionLog;

    @Autowired
    private WebVisitService webVisitService;


    @Pointcut(value = "@annotation(bussinessLog)")
    public void pointcut(BussinessLog bussinessLog) {

    }

    @Around(value = "pointcut(bussinessLog)")
    public Object doAround(ProceedingJoinPoint joinPoint, BussinessLog bussinessLog) throws Throwable {

        //先执行业务
        Object result = joinPoint.proceed();

        try {
            // 日志收集
            handle(joinPoint);
        } catch (Exception e) {
            log.error("日志记录出错!", e);
        }

        return result;
    }

    private void handle(ProceedingJoinPoint point) throws Exception {

        HttpServletRequest request = RequestHolder.getRequest();

        Method currentMethod = AspectUtil.INSTANCE.getMethod(point);
        //获取操作名称
        BussinessLog annotation = currentMethod.getAnnotation(BussinessLog.class);

        boolean save = annotation.save();

        EBehavior behavior = annotation.behavior();

        String bussinessName = AspectUtil.INSTANCE.parseParams(point.getArgs(), annotation.value());

        String ua = RequestUtil.getUa();

        log.info("{} | {} - {} {} - {}", bussinessName, IpUtils.getIpAddr(request), RequestUtil.getMethod(), RequestUtil.getRequestUrl(), ua);
        if (!save) {
            return;
        }

        // 获取参数名称和值
        Map<String, Object> nameAndArgsMap = AopUtils.getFieldsName(point);

        Map<String, String> result = EBehavior.getModuleAndOtherData(behavior, nameAndArgsMap, bussinessName);

        AopUtils.getFieldsName(point);

        if (result != null) {
            String userUid = "";
            if (request.getAttribute(SysConf.USER_UID) != null) {
                userUid = request.getAttribute(SysConf.USER_UID).toString();
            }
            webVisitService.addWebVisit(userUid, request, behavior.getBehavior(), result.get(SysConf.MODULE_UID), result.get(SysConf.OTHER_DATA));
        }
    }
}

这里使用了一个AspectUtils工具类

package com.moxi.mogublog.utils;

import com.alibaba.fastjson.JSON;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.Signature;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.util.StringUtils;

import java.lang.reflect.Method;
import java.util.List;

/**
 * AOP相关的工具
 * @author 陌溪
 * @date 2020年2月27日08:44:28
 */
public enum AspectUtil {

    INSTANCE;

    /**
     * 获取以类路径为前缀的键
     *
     * @param point 当前切面执行的方法
     */
    public String getKey(JoinPoint point, String prefix) {
        String keyPrefix = "";
        if (!StringUtils.isEmpty(prefix)) {
            keyPrefix += prefix;
        }
        keyPrefix += getClassName(point);
        return keyPrefix;
    }

    /**
     * 获取当前切面执行的方法所在的class
     *
     * @param point 当前切面执行的方法
     */
    public String getClassName(JoinPoint point) {
        return point.getTarget().getClass().getName().replaceAll("\\.", "_");
    }

    /**
     * 获取当前切面执行的方法的方法名
     *
     * @param point 当前切面执行的方法
     */
    public Method getMethod(JoinPoint point) throws NoSuchMethodException {
        Signature sig = point.getSignature();
        MethodSignature msig = (MethodSignature) sig;
        Object target = point.getTarget();
        return target.getClass().getMethod(msig.getName(), msig.getParameterTypes());
    }

    public String parseParams(Object[] params, String bussinessName) {
        if (bussinessName.contains("{") && bussinessName.contains("}")) {
            List<String> result = RegexUtils.match(bussinessName, "(?<=\\{)(\\d+)");
            for (String s : result) {
                int index = Integer.parseInt(s);
                bussinessName = bussinessName.replaceAll("\\{" + index + "}", JSON.toJSONString(params[index - 1]));
            }
        }
        return bussinessName;
    }
}

以及AOPUtils

package com.moxi.mogublog.utils;

import com.alibaba.fastjson.JSON;
import lombok.extern.slf4j.Slf4j;
import org.apache.ibatis.javassist.*;
import org.apache.ibatis.javassist.bytecode.CodeAttribute;
import org.apache.ibatis.javassist.bytecode.LocalVariableAttribute;
import org.apache.ibatis.javassist.bytecode.MethodInfo;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.Signature;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.core.DefaultParameterNameDiscoverer;
import org.springframework.core.ParameterNameDiscoverer;
import org.springframework.web.multipart.MultipartFile;

import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import java.lang.reflect.Method;
import java.util.HashMap;
import java.util.Map;

/**
 * 切面相关工具类
 *
 * @author: 陌溪
 * @create: 2020-01-21-12:34
 */
@Slf4j
public class AopUtils {

    /**
     * 获取参数名和值
     * @param joinPoint
     * @return
     */
    public static Map getFieldsName(ProceedingJoinPoint joinPoint) throws ClassNotFoundException, NoSuchMethodException {
        // 参数值
        Object[] args = joinPoint.getArgs();

        Signature signature = joinPoint.getSignature();
        MethodSignature methodSignature = (MethodSignature) signature;
        String[] parameterNames = methodSignature.getParameterNames();

        // 通过map封装参数和参数值
        HashMap<String, Object> paramMap = new HashMap();
        for (int i = 0; i < parameterNames.length; i++) {
            paramMap.put(parameterNames[i], args[i]);
        }
        return paramMap;
    }
}

需要注意的是,我们在进行日志收集的时候,采用的是@Async注解修饰,也就是异步调用

 在Spring中,基于@Async标注的方法,称之为异步方法;这些方法将在执行的时候,将会在独立的线程中被执行,调用者无需等待它的完成,即可继续其他的操作。

    @Async
    @Override
    public void addWebVisit(String userUid, HttpServletRequest request, String behavior, String moduleUid, String otherData) {

        //增加记录(可以考虑使用AOP)
        Map<String, String> map = IpUtils.getOsAndBrowserInfo(request);
        String os = map.get("OS");
        String browser = map.get("BROWSER");
        WebVisit webVisit = new WebVisit();
        String ip = IpUtils.getIpAddr(request);
        webVisit.setIp(ip);

        //从Redis中获取IP来源
        String jsonResult = stringRedisTemplate.opsForValue().get("IP_SOURCE:" + ip);
        if (StringUtils.isEmpty(jsonResult)) {
            String addresses = IpUtils.getAddresses("ip=" + ip, "utf-8");
            if (StringUtils.isNotEmpty(addresses)) {
                webVisit.setIpSource(addresses);
                stringRedisTemplate.opsForValue().set("IP_SOURCE" + BaseSysConf.REDIS_SEGMENTATION + ip, addresses, 24, TimeUnit.HOURS);
            }
        } else {
            webVisit.setIpSource(jsonResult);
        }
        webVisit.setOs(os);
        webVisit.setBrowser(browser);
        webVisit.setUserUid(userUid);
        webVisit.setBehavior(behavior);
        webVisit.setModuleUid(moduleUid);
        webVisit.setOtherData(otherData);
        webVisit.insert();
    }

tip:在使用@Async注解时候,需要在启动类中加入  @EnableAsync  才能够开启异步功能

指定接口进行收集

最后我们使用  @BussinessLog 在我们需要收集的日志出进行标记,标记后AOP的环绕通知 就会获取该接口的相关参数,将其实例化到数据库中

  示例代码如下:

    @BussinessLog(value = "发表评论", behavior = EBehavior.PUBLISH_COMMENT)
    @ApiOperation(value = "增加评论", notes = "增加评论")
    @PostMapping("/add")
    public String add(@Validated({Insert.class}) @RequestBody CommentVO commentVO, BindingResult result) {

        QueryWrapper<WebConfig> queryWrapper = new QueryWrapper<>();
        queryWrapper.eq(SysConf.STATUS, EStatus.ENABLE);
        WebConfig webConfig = webConfigService.getOne(queryWrapper);
        if (SysConf.CAN_NOT_COMMENT.equals(webConfig.getStartComment())) {
            return ResultUtil.result(SysConf.ERROR, MessageConf.NO_COMMENTS_OPEN);
        }
        ThrowableUtils.checkParamArgument(result);

        if (commentVO.getContent().length() > SysConf.TWO_TWO_FIVE) {
            return ResultUtil.result(SysConf.ERROR, MessageConf.COMMENT_CAN_NOT_MORE_THAN_225);
        }
        Comment comment = new Comment();
        comment.setSource(commentVO.getSource());
        comment.setBlogUid(commentVO.getBlogUid());
        comment.setContent(commentVO.getContent());
        comment.setUserUid(commentVO.getUserUid());
        comment.setToUid(commentVO.getToUid());
        comment.setToUserUid(commentVO.getToUserUid());
        comment.setStatus(EStatus.ENABLE);
        comment.insert();

        User user = userService.getById(commentVO.getUserUid());

        //获取图片
        if (StringUtils.isNotEmpty(user.getAvatar())) {
            String pictureList = this.pictureFeignClient.getPicture(user.getAvatar(), SysConf.FILE_SEGMENTATION);
            if (webUtils.getPicture(pictureList).size() > 0) {
                user.setPhotoUrl(webUtils.getPicture(pictureList).get(0));
            }
        }
        comment.setUser(user);

        return ResultUtil.result(SysConf.SUCCESS, comment);
    }

最后用户的日志记录也能够成功记录下来了
