JSpider（1）：配置与运行

运行:

1,下载jspider-0.5.0-dev.zip,解压缩.

2,开始->运行->cmd,进入命令行窗口,进入jspider-0.5.0-dev/bin目录

3, 试着抓取网站http: //j-spider.sourceforge.net的内容:

jspider http: //j-spider.sourceforge.net >> out.txt

可以看见屏幕上显示:

JSpider v0.5.0 DEV (http://j-spider.sourceforge.net)
Build: 20030502
Started from .
[Engine] jspider.home=..
[Engine] default output folder=..\output
[Engine] starting with configuration 'default'

bin目录下多了两个文件,out.txt, velocity.log.

out.txt内容如下:

可以看出，具体的spider，parse,dump动作都是由插件实现的。velocity.log是velocity插件的日志。

默认输出目录是output,进去可以看见7个文件: 200.out, 404.out, log4j.out, README.txt, velocity-dump.out, velocity-trace.out, xml-dump.xml;这些文件记录的就是扫描结果。*.out是文本文件,可以用文本编辑器打开.output里面没有http页面,也就是说默认配置不保存抓取下来的页面.

配置文件在conf目录下.配置文件有两种：

(1)*.properties――程序配置文件，配置程序的行为

如conf\default\plugins\download\sites.properties文件内容：

# -----------------------------------------------------------------------------
# Websites configuration file
# -----------------------------------------------------------------------------
#
# $Id: sites.properties,v 1.4 2003/04/25 21:28:55 vanrogu Exp $
#
# -----------------------------------------------------------------------------
jspider.site.config.base=base
jspider.site.config.default=skip

(2)*.vm――输出格式配置文件，配置程序的输出。JSpider采用的是第三方工具velocity。

*.vm是velocity模板文件。如，conf\default\plugins\velocity\engineSpideringStoppedEvent.vm：

[${eventName}]

known urls

. : ${event.summary.known}

visited urls

.. : ${event.summary.visited}

parsed urls

parse ignored urls

.. : ${event.summary.ignoredForParsing}

parse error urls

. : ${event.summary.parseErrors}

not visited urls

. : ${event.summary.notVisited}

fetching ignored urls .. : ${event.summary.ignoredForFetching}

forbidden urls

: ${event.summary.forbidden}

fetch error urls

. : ${event.summary.fetchErrors}

not yet visited urls .. : ${event.summary.unvisited}
