使用Java操作ElasticSearch1.7程序

    ElasticSearch是一个基于Lucene的搜索服务器。它提供了一个分布式多用户能力的全文搜索引擎，基于RESTful web接口。Elasticsearch是用Java开发的，并作为Apache许可条款下的开放源码发布，是第二流行的企业搜索引擎。设计用于云计算中，能够达到实时搜索，稳定，可靠，快速，安装使用方便。

   最近学习了一下ElasticSearch的Java API使用，简易代码如下：

 

package com.learn.test;

import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.common.settings.ImmutableSettings;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.action.index.IndexResponse;

import java.io.IOException;

import org.codehaus.jackson.JsonProcessingException;
import org.codehaus.jackson.map.ObjectMapper;

public class TestElastic
{
    public static void main(String[] args)
    {
        UserModel user = new UserModel();
        user.setId(1);
        user.setName("李四");
        user.setAge("101");
        user.setSex("1231");
        user.setTel("Tel");
        String jsondata = toJson(user);
        System.out.println("封装的json:"+jsondata);

        Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "tang-elasticsearch").build();
        Client client = new TransportClient(settings).addTransportAddress(

new<span style="font-family: Arial, Helvetica, sans-serif;"> InetSocketTransportAddress("192.168.15.1", 9300));</span>

IndexResponse res = client.prepareIndex().setIndex("school").setType("class").setId("10").setSource(

                                        jsondata).execute().actionGet();
        System.out.println("索引创建成功,版本号："+res.getVersion());


        client.close();
    }

    public static String toJson(Object o)
    {
        try
        {
            ObjectMapper objectMapper = new ObjectMapper();
            return objectMapper.writeValueAsString(o);
        }
        catch (JsonProcessingException e)
        {
            e.printStackTrace();
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }

        return "";
    }

}

class UserModel
{
    private int id;
    private String name;
    private String age;
    private String sex;
    private String tel;

    public int getId()
    {
        return id;
    }

    public void setId(int id)
    {
        this.id = id;
    }

    public String getName()
    {
        return name;
    }

    public void setName(String name)
    {
        this.name = name;
    }

    public String getAge()
    {
        return age;
    }

    public void setAge(String age)
    {
        this.age = age;
    }

    public String getSex()
    {
        return sex;
    }

    public void setSex(String sex)
    {
        this.sex = sex;
    }

    public String getTel()
    {
        return tel;
    }

    public void setTel(String tel)
    {
        this.tel = tel;
    }
}
