Elasticsearch教程(二）java集成Elasticsearch
1、添加maven
<!--tika抽取文件内容 -->
<dependency>
<groupId>org.apache.tika</groupId>
<artifactId>tika-core</artifactId>
<version>1.12</version>
</dependency>
<dependency>
<groupId>org.apache.tika</groupId>
<artifactId>tika-parsers</artifactId>
<version>1.12</version>
</dependency>
<!--tika end-->
<!--bboss操作elasticsearch-->
<dependency>
<groupId>com.bbossgroups.plugins</groupId>
<artifactId>bboss-elasticsearch-rest-jdbc</artifactId>
<version>5.5.7</version>
</dependency>
<!--Hanlp自然语言分词-->
<dependency>
<groupId>com.hankcs</groupId>
<artifactId>hanlp</artifactId>
<version>portable-1.7.1</version>
</dependency>
<!-- httpclient -->
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.5</version>
</dependency>
注意：与spring集成时需要注意版本号，版本太高会造成jar包冲突，tika-parsers 依赖poi.jar包,所以项目中不需要单独添加poi.jar，会造成冲突。
