介绍

丑牛迷你采集器是一款基于Java Swing开发的专业的网络数据采集/信息挖掘处理软件,通过灵活的配置,可以很轻松迅速地从 网页上抓取结构化的文本、图片、文件等资源信息,可编辑筛选处理后选择发布到网站

软件架构

JAVACOO-CRAWLER采用的是模块化设计,各个模块由一个控制器类(CrawlController类)来协调工作,控制器就是爬虫的核心。 CrawlController类是整个爬虫的总控制者,控制整个采集工作的的起点,决定采集任务的开始,暂停,继续,结束。 CrawlController类主要包括以下模块:分别是爬虫的配置参数,字符集帮助类, HttpCilent对象,HTML解析器包装类,爬虫边界控制器,爬虫线程控制器,处理器链,过滤器工厂,整体架构图如下:

  1. 爬虫配置参数(CrawlScope): 存储当前爬虫的配置信息,如采集页面编码,采集过滤器列表,采集种子列表,爬虫持久对象实现类等,CrawlController根据配置参数来初始化其他模块。
  2. 字符集帮助类(CharsetHandler):根据当前爬虫配置参数中字符集配置来初始化,备整个采集过程使用。
  3. HttpCilent对象(HttpClient):根据当前爬虫配置参数初始化HttpClient对象,如:设置代理,设置连接/请求超时,最大连接数等。
  4. HTML解析器包装类(HtmlParserWrapper):对HtmlParser解析器进行特殊化封装,以便满足采集任务的需要。
  5. 爬虫边界控制器(Frontier):主要是加载爬行种子链接并根据加载的种子链接初始化任务队列,以备线程控制器(ProcessorManager)开启的任务执行线程(ProcessorThread)使用。
  6. 爬虫线程控制器(ProcessorManager):主要是控制任务执行线程数量,开启指定数目的任务执行线程执行任务。
  7. 过滤器工厂(FilterFactory):注册当前爬虫配置参数中过滤器集合,供采集任务查询使用。
  8. 主机缓存(HostCache):缓存HttpHost对象。
  9. 处理器链(ProcessorChainList):默认构建了5中处理链,依次是,预取链,提取链,抽取链,写链,提交链,在任务处理线程中将使用。
  • 预取链:主要是做一些准备工作,例如,对处理进行延迟和重新处理,否决随后的操作。
  • 提取链:主要是下载网页,进行 DNS 转换,填写请求和响应表单。
  • 抽取链 : 当提取完成时 , 抽取感兴趣的 HTML 和 JavaScript 等 。
  • 写链:存储抓取结果,可以在这一步直接做全文索引。
  • 提交链:做和此 URL 相关操作的最后处理。
