3. 测试类（SolrJ的添加索引为例）

import org.apache.solr.client.solrj.SolrClient;

import org.apache.solr.client.solrj.SolrServerException;

import org.apache.solr.client.solrj.impl.HttpSolrClient;

import org.apache.solr.common.SolrInputDocument;

import java.io.IOException;

import java.util.UUID;

public class Main {

public static void main(String[] args)throws IOException, SolrServerException {

System.out.println("Hello Solr...");

String urlString ="http://localhost:8983/solr/core1";

SolrClient solrClient =new HttpSolrClient.Builder(urlString).build();

System.out.println("INFO: Insert a document into Solr...");

SolrInputDocument doc =new SolrInputDocument();

doc.addField("id","8");

doc.addField("COMPANY","ebay");

doc.addField("LOCATION","Silicon Vally（硅谷）");

doc.addField("DESC-CO","ebay是一个与Amazon相似的电商网站，类似中国的阿里巴巴。开发Java，Web应用是很有必要的。");

doc.addField("uuid",UUID.randomUUID().toString());

solrClient.add(doc);

solrClient.commit();// periodically flush

        System.out.println("INFO: Insert the document into Solr Successfully");

}

}

4. 备注

Solr里面设置了uuid为唯一键。
