Elasticsearch 2.3.3 中文IK分词插件安装视频教程

2019独角兽企业重金招聘Python工程师标准>>>

本文所提供的视频是依据此文章进行录制。http://my.oschina.net/besthadoop/blog/698698

录制过程使用了跟Elasticsearch 2.3.3匹配的IK分词器，大家可以直接下载该IK分词器，而不用安装maven自己编译打包。下载地址：http://www.besthadoop.com/course/28/material/

大家在使用IK分词的时候，一定要注意配置这几个属性，否则IK分词是不生效的。

index.analysis.analyzer.default.type: ik

动态更改词典的源码，可以写一个Servlet进行修改。

package com.best.dic;

import java.io.IOException;
import java.io.OutputStream;
import java.util.UUID;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet("/GetDic")
public class GetDic extends HttpServlet {
	private static final long serialVersionUID = 1L;

	/**
	 * @see HttpServlet#HttpServlet()
	 */
	public GetDic() {
		super();
		// TODO Auto-generated constructor stub
	}

	protected void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		response.setHeader("Last-Modified", System.currentTimeMillis() + "");
		response.setHeader("ETag", UUID.randomUUID().toString());
		// 这句话的意思，是让浏览器用utf8来解析返回的数据
		response.setHeader("Content-type", "text/html;charset=UTF-8");
		StringBuilder builder = new StringBuilder("码农");
		builder.append("\n");
		builder.append("58码农");
		builder.append("\n");
		builder.append("匠心精神");
		OutputStream ps = response.getOutputStream();
		// 这句话的意思，使得放入流的数据是utf8格式
		ps.write(builder.toString().getBytes("UTF-8"));
	}

	/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse
	 *      response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		// TODO Auto-generated method stub
		doGet(request, response);
	}

}

大家也可以加入群进行交流。
