希望的效果為

需求

用戶點(diǎn)擊了某個(gè)界面，請求了后臺(tái)某個(gè)接口。接口請求到后臺(tái)后，記錄請求的數(shù)據(jù)到數(shù)據(jù)庫中。

實(shí)現(xiàn)方式

1、自定義一個(gè)注解，被加注解的方法，請求的數(shù)據(jù)被保存下來
2、定義一個(gè)aop 去攔截被注解的方法
3、寫一個(gè)線程池、執(zhí)行攔截后的邏輯。也就是保存到數(shù)據(jù)庫中

效果圖

這里寫圖片描述

查看到剛剛請求用戶列表界面的執(zhí)行情況

這里寫圖片描述

實(shí)現(xiàn)步驟

1、自定義注解

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface SLog {
    String value() default "";
}

定義一個(gè)aop攔截注解

@Aspect
@Component
public class SLogAspect {

    /**
     * 保存日志到數(shù)據(jù)庫的線程池
     */
    ThreadFactory threadFactory = new ThreadFactoryBuilder().setNameFormat("SLogAspect-Thread-%d").build();

    ExecutorService executor = new ThreadPoolExecutor(5,200,0L, TimeUnit.MILLISECONDS,
            new LinkedBlockingQueue<Runnable>(1024),
            threadFactory,
            new ThreadPoolExecutor.AbortPolicy());


    @Pointcut("@annotation(com.slife.annotation.SLog)")
    public void logPointCut() {
    }

    @Around("logPointCut()")
    public Object around(ProceedingJoinPoint point) throws Throwable {
        long beginTime = System.currentTimeMillis();
        // 執(zhí)行方法
        Object result = point.proceed();
        // 執(zhí)行時(shí)長(毫秒)
        long time = System.currentTimeMillis() - beginTime;

        // 獲取request
        HttpServletRequest request = ServletUtils.getHttpServletRequest();
        //獲取請求的ip
        String ip = IPUtils.getIpAddr(request);
        SaveLogTask saveLogTask = new SaveLogTask(point, time, ip);
        //保存日志到數(shù)據(jù)庫
        executor.execute(saveLogTask);

        return result;
    }


}

線程池執(zhí)行保存數(shù)據(jù)到數(shù)據(jù)庫

    private SlifeLogDao slifeLogDao = ApplicationContextRegister.getBean(SlifeLogDao.class);

    private ProceedingJoinPoint joinPoint;

    public SaveLogTask(ProceedingJoinPoint point, long time, String ip) {

        Method method = signature.getMethod();

        SlifeLog slifeLog = new SlifeLog();
        SLog sLog = method.getAnnotation(SLog.class);

        if (slifeLog != null) {
            // 注解上的描述
            slifeLog.setMsg(sLog.value());
        }
        // 請求的方法名
        String className = joinPoint.getTarget().getClass().getName();
        String methodName = signature.getName();
        slifeLog.setSrc(className + "." + methodName + "()");

        // 請求的參數(shù)
        Object[] args = joinPoint.getArgs();
        try {
            String params = JSON.toJSONString(args[0]);
            slifeLog.setParams(params);
        } catch (Exception e) {

        }

        // 設(shè)置IP地址
        slifeLog.setIp(ip);
        // 用戶名
        ShiroUser currUser = SlifeSysUser.ShiroUser();

        if (null == currUser) {
            if (null != slifeLog.getParams()) {
                slifeLog.setName(slifeLog.getParams());
                slifeLog.setLoginName(slifeLog.getParams());
            } else {
                slifeLog.setName("獲取用戶信息為空");
                slifeLog.setLoginName("獲取用戶信息為空");
                slifeLog.setCreateId(-1L);
            }
        } else {
            slifeLog.setName(currUser.getName());
            slifeLog.setLoginName(currUser.getUsername());

        }

        slifeLog.setUseTime(time);

        // 保存系統(tǒng)日志
        slifeLogDao.insert(slifeLog);
    }
}

給需要的方法加注解

    @SLog("獲取用戶列表數(shù)據(jù)")
    @ApiOperation(value = "獲取用戶列表數(shù)據(jù)", notes = "獲取用戶列表:使用約定的DataTable")
    @PostMapping(value = "/list")
    @ResponseBody
    public DataTable<SysUser> list(@RequestBody DataTable dt, ServletRequest request) {
        return sysUserService.pageSearch(dt);
    }




  @SLog("獲取用戶列表數(shù)據(jù)")

簡單的一個(gè) 記錄請求的日志 實(shí)現(xiàn)。

說明

這里把保存到數(shù)據(jù)庫的邏輯寫到了一個(gè)線程池中，主要是不希望記錄日志的邏輯影響了用戶請求數(shù)據(jù)接口的邏輯，和性能。
