Update FileCacheQueueScheduler.java
这样是不是更严谨? 否则的话,中断后再次启动时, (第一个)入口地址仍会被添加到队列及写入到文件中.
但是现在有另外一个问题存在,如第一遍全部抓取完毕了(通过spider.getStatus==Stopped判断),休眠24小时,再来抓取(通过递归调用抓取方法).
这时不同于中断后再启动,lineReader==cursor, 于是初始化时队列为空,入口地址又在urls集合中了, 故导致抓取线程马上就结束了.这样的话就没有办法去抓取网站上的新增内容了.
解决方案一:
判断抓取完毕后,紧接着覆盖cursor文件,第二次来抓取时,curosr为0, 于是将urls.txt中的所有url均放入队列中了, 可以通过这些url来发现新增url.
方案二:
对方案一进行优化,方案一虽然可以满足业务要求,但会做很多无用功,如仍会对所有旧target url进行下载,抽取,持久化等操作.而新增的内容一般都会在HelpUrl中, 比如某一页多了一个新帖子,或者多了几页内容. 故第二遍及以后来爬取时可以仅将HelpUrl放入队列中.
希望能给予反馈,我上述理解对不对, 有什么没有考虑到的情况或者有更简单的方案?谢谢!

Update FileCacheQueueScheduler.java
在使用过程中发现urls.txt文件存在重复URL的情况,经跟踪源代码,发现初始化加载文件后,读取所有的url放入一集合中,但是之后添加待抓取URL时并未判断是否已存在该集合中(即文件中)了,故导致文件中重复URL的情况.故据此对源码做了修改,还请作者审阅.
