为什么选择结巴分词
分词效率高词料库构建时使用的是jieba (python)
结巴分词Java版本
下载
git clone https://github.com/huaban/jieba-analysis
编译
cd jieba-analysis
mvn install
注意
如果mvn版本较高，需要修改pom.xml文件，在plugins前面增加
solr tokenizer版本
https://github.com/sing1ee/analyzer-solr (solr 5)https://github.com/sing1ee/jieba-solr.git (solr 4)
支持solr 6或7或更高
如果你的solr像我一样，版本比较新，需要对代码稍做修改，但改动其实不大。(根据给编译时报的错误做修改即可)

集成到solr
拷贝jar包到solr的目录下：server/solr-webapp/webapp/WEB-INF/lib
