前面我们已经成功搭建了solrcloud集群，下面我们通过solrj演示一下索引的创建，删除及查询。

1.修改schema.xml，增加field

首先添加中文分词，查看：[http://blog.csdn.net/zhu\_tianwei/article/details/46711511][http_blog.csdn.net_zhu_tianwei_article_details_46711511]

添加索引字段

上传 schema.xml到zookeeper

java -classpath .:/home/slim/solrcloud/solr-lib/\* org.apache.solr.cloud.ZkCLI -cmd upconfig -zkhost 192.168.100.90:2181 -confdir /home/slim/solrcloud/config-files -confname testconf

2.实例

package cn.slimsmart.solr.demo.solrcloud;
    
    import java.io.IOException;
    import java.util.ArrayList;
    import java.util.Collection;
    
    import org.apache.solr.client.solrj.SolrClient;
    import org.apache.solr.client.solrj.SolrQuery;
    import org.apache.solr.client.solrj.SolrServerException;
    import org.apache.solr.client.solrj.impl.CloudSolrClient;
    import org.apache.solr.client.solrj.response.QueryResponse;
    import org.apache.solr.common.SolrDocument;
    import org.apache.solr.common.SolrDocumentList;
    import org.apache.solr.common.SolrInputDocument;
    
    //SolrCloud 索引增删查
    public class SolrCloudTest {
    
    	private static CloudSolrClient cloudSolrClient;
    
    	private static synchronized CloudSolrClient getCloudSolrClient(final String zkHost) {
    		if (cloudSolrClient == null) {
    			try {
    				cloudSolrClient = new CloudSolrClient(zkHost);
    			} catch (Exception e) {
    				e.printStackTrace();
    			}
    		}
    		return cloudSolrClient;
    	}
    
    	private static void addIndex(SolrClient solrClient) {
    		try {
    			SolrInputDocument doc1 = new SolrInputDocument();
    			doc1.addField("id", "421245251215121452521251");
    			doc1.addField("name", "张三");
    			doc1.addField("age", 30);
    			doc1.addField("desc", "张三是个农民，勤劳致富，奔小康");
    
    			SolrInputDocument doc2 = new SolrInputDocument();
    			doc2.addField("id", "4224558524254245848524243");
    			doc2.addField("name", "李四");
    			doc2.addField("age", 45);
    			doc2.addField("desc", "李四是个企业家，白手起家，致富一方");
    
    			SolrInputDocument doc3 = new SolrInputDocument();
    			doc3.addField("id", "2224558524254245848524299");
    			doc3.addField("name", "王五");
    			doc3.addField("age", 60);
    			doc3.addField("desc", "王五好吃懒做，溜须拍马，跟着李四，也过着小康的日子");
    
    			Collection<SolrInputDocument> docs = new ArrayList<SolrInputDocument>();
    			docs.add(doc1);
    			docs.add(doc2);
    			docs.add(doc3);
    			solrClient.add(docs);
    			solrClient.commit();
    		} catch (SolrServerException e) {
    			System.out.println("Add docs Exception !!!");
    			e.printStackTrace();
    		} catch (IOException e) {
    			e.printStackTrace();
    		} catch (Exception e) {
    			System.out.println("Unknowned Exception!!!!!");
    			e.printStackTrace();
    		}
    	}
    
    	public static void search(SolrClient solrClient, String String) {
    		SolrQuery query = new SolrQuery();
    		query.setQuery(String);
    		try {
    			QueryResponse response = solrClient.query(query);
    			SolrDocumentList docs = response.getResults();
    
    			System.out.println("文档个数：" + docs.getNumFound());
    			System.out.println("查询时间：" + response.getQTime());
    
    			for (SolrDocument doc : docs) {
    				String id = (String) doc.getFieldValue("id");
    				String name = (String) doc.getFieldValue("name");
    				Integer age = (Integer) doc.getFieldValue("age");
    				String desc = (String) doc.getFieldValue("desc");
    				System.out.println("id: " + id);
    				System.out.println("name: " + name);
    				System.out.println("age: " + age);
    				System.out.println("desc: " + desc);
    				System.out.println();
    			}
    		} catch (SolrServerException e) {
    			e.printStackTrace();
    		} catch (Exception e) {
    			System.out.println("Unknowned Exception!!!!");
    			e.printStackTrace();
    		}
    	}
    
    	public void deleteAllIndex(SolrClient solrClient) {
    		try {
    			solrClient.deleteByQuery("*:*");// delete everything!
    			solrClient.commit();
    		} catch (SolrServerException e) {
    			e.printStackTrace();
    		} catch (IOException e) {
    			e.printStackTrace();
    		} catch (Exception e) {
    			System.out.println("Unknowned Exception !!!!");
    			e.printStackTrace();
    		}
    	}
    
    	public static void main(String[] args) throws IOException {
    		 final String zkHost = "192.168.100.90:2181";       
             final String  defaultCollection = "testcollection";  
             final int  zkClientTimeout = 20000;  
             final int zkConnectTimeout = 1000;  
               
             CloudSolrClient cloudSolrClient = getCloudSolrClient(zkHost);         
             System.out.println("The Cloud cloudSolrClient Instance has benn created!");            
             cloudSolrClient.setDefaultCollection(defaultCollection);  
             cloudSolrClient.setZkClientTimeout(zkClientTimeout);  
             cloudSolrClient.setZkConnectTimeout(zkConnectTimeout);                   
             cloudSolrClient.connect();  
             System.out.println("The cloud Server has been connected !!!!");      
             //创建索引
             SolrCloudTest.addIndex(cloudSolrClient);
             //查询
             SolrCloudTest.search(cloudSolrClient, "context:李四");      
             cloudSolrClient.close();
    	}
    }

上面实例中可以看出查询是需要指定查询的字段context，solr默认的查询字段为text，可以通过修改solrconfig.xml配置，修改默认查询字段：

<str name="df">text</str> 修改为<str name="df">content</str>，这样的话就不需要在Query中进行查询时使用“context:李四”这样的格式，直接查询“李四”就可以了。  
SolrCloudTest.search(cloudSolrClient, "李四");

需要重启tomcat。
