WebMagic 是干嘛的？ WebMagic 是一个 Java 平台上的开源爬虫框架，其设计参考了 Scrapy，实现则参考了 HttpClient 和 Jsoup。其由四大组件组成： Downloader，负责下载网页，使用 HttpClient。 PageProcessor，负责解析网页和链接发现，使用 Jsoup 和 Xsoup。 Scheduler，负责管理待抓取的 URL 和去重。 Pipeline，负责结果数据的持久化。 快速开始 （1）依赖引入 ext { versions = [ "web_magic": '0.7.3' ] } dependencies { // 这里有自己项目的日志实现 compile project(':base') compile("us.codecraft:webmagic-core:${versions.web_magic}") { exclude group: 'org.slf4j', module: 'slf4j-log4j12' // 移除默认的日志实现 } compile("us.codecraft:webmagic-extension:${versions.web_magic}") { exclude group: 'org.slf4j', module: 'slf4j-log4j12' } } （2）快速开始 爬取

模拟servlet执行 浏览器请求WEB服务器上的资源，WEB服务器返回给浏览器 浏览器的入口不同(访问路径)，访问的资源也不同。 我们需要使用xml约束(DTD或schema);为了获得xml的内容，我们需要使用dom4j进行解析。 XML(不同路径(/hello)执行不同的资源( HeIIoMyServlet)) XML可扩展的标记语言 标签可自定义的 包下创建xml 文件 new → other → XMLFile 粘贴web-app_ 2_ 3.dtd文件 复制web-app_ 2_ 3.dtd的文档声明到xml文件 存放数据 <?xml version="1.0" encoding="UTF-8"?> XML文档声明第一行 顶格写 versioin:XML版本encoding:文档的编码 默认utf-8: //加入Java开发交流君样：756584822一起吹水聊天 <school name="oracle" size="3"> 元素（不以XML,xml开头）一个根元素 <person> 属性值必须使用单引或双引 <name>张三<</name> 元素内容 转义符 写法与html相同 <age><![CDATA[18><]]></age>CDATA区<![CDATA[内容自动转义]]> <c/> 空元素 </person> <!--注释--> </school>
