在项目中使用paoding分词

本文中使用paoding2.0.4

1.准备工作

   需要的文件：

   paoding-analysis.jar

   dic

   paoding-analysis.properties

2.安装导入

   将paoding-analysis.jar放到classpath 目录下并且导入工程

   修改paoding-analysis.properties ,将paoding.dic.home设置为字典的存放目录。例如，字典放在classpath目录下，则设置为“ paoding.dic.home=classpath:dic”。放在其他位置按照类似“

paoding.dic.home=/paodingdic/paoding/dic

”进行修改。

   在配置文件中加入下列内容：

paoding.knife.class.letterKnife=net.paoding.analysis.knife.LetterKnife

 paoding.knife.class.numberKnife=net.paoding.analysis.knife.NumberKnife

 paoding.knife.class.cjkKnife=net.paoding.analysis.knife.CJKKnife

3.使用。

    首先加入import net.paoding.analysis.analyzer.PaodingAnalyzer;

    将代码中原来使用的analyzer，例如StandardAnalyzer替换为PaodingAnalyzer即可。

运行程序，有可能会出现如下的错误：

error in handler jarPath=/C:/Users/Administrator/Workspaces/MyEclipse 8.5/lucene0623/lib/paoding-analysis.jar!/

出现这个错误是因为Paoding的jar文件以及配置文件的存放路径中存在空格，比如此处“MyEclipse 8.5”中间有空格。修改文件夹名称，将空格去掉，就可以正常运行了。

正常运行时控制台会有如下提示信息：
