solrJ 基本使用

周末，随便写点东西，介绍介绍solrJ的基本使用，直接上代码：

创建索引：

public static void main(String[] args) throws IOException, SolrServerException {    //初始化索引连接的时候，可以根绝实际情况优化连接，这边只是一个main方法demo    HttpSolrServer server = new HttpSolrServer("http://localhost:8180/solr/xmcore");    for (int i = 0; i < 10; ++i) {        SolrInputDocument doc = new SolrInputDocument();        //与schame.xml中field对应        doc.addField("id", "100"+i);        doc.addField("name", "xiaomengge"+i);        doc.addField("age", 30);        doc.addField("address", "江苏南京苏宁易购物品质量很好"+i);        server.add(doc);        if (i % 100 == 0)            server.commit(); // periodically flush    }    //      SolrInputDocument doc = new SolrInputDocument();    //      doc.addField("id", "1000");    //      doc.addField("name", "测试分词");    //      doc.addField("age", 30);    //      doc.addField("address", "江苏南京苏宁易购物品质量很好");    //      server.add(doc);    //      SolrInputDocument doc = new SolrInputDocument();    //      doc.addField("id", "1001");    //      doc.addField("name", "测试分词1");    //      doc.addField("age", 30);    //      doc.addField("address", "Pigeon贝亲奶瓶清洁剂150ml");    //      server.add(doc);    server.commit();}

查询索引：

public static void main(String[] args) throws MalformedURLException, SolrServerException {    HttpSolrServer solr = new HttpSolrServer("http://localhost:8180/solr/xmcore");      SolrQuery params = new SolrQuery();    //两种查询方式，一种是params.set("q", "address:钢铁侠"); qf，defType可以忽略 ，推荐下面这种查询方式，可以设置field的权重    params.set("q", "钢铁侠");    params.set("qf", "address^0.8 book_name^0.7");    params.set("defType", "edismax");    params.set("start", "0");    params.addFilterQuery("suggest:钢铁侠  AND suggest:复仇者");    params.addFilterQuery("querytext:aaa  OR querytext:bbb");    QueryResponse response = solr.query(params);    SolrDocumentList results = response.getResults();    for (int i = 0; i < results.size(); ++i) {    System.out.println(results.get(i));    }}

单例方式初始化SolrCloud连接

import org.apache.solr.client.solrj.impl.CloudSolrServer;import org.slf4j.Logger;import org.slf4j.LoggerFactory;public class SolrClientFactory {     private static final Logger LOGGER = LoggerFactory.getLogger(SolrClientFactory.class);       private static SolrClientFactory solrClientFactory = null;        private static CloudSolrServer cloudSolrServer = null;        private SolrClientFactory() {}        public static synchronized SolrClientFactory getInstance() {            if (solrClientFactory == null) {                solrClientFactory = new SolrClientFactory();            }            return solrClientFactory;        }    public void initSolrClient() {        LOGGER.info("init solr client");        //ase.query.solrclient.url 为集群中zookeeper的IP与端口        //ase.query.solrclient.url=172.172.177.47:2181,172.172.177.47:2281,172.172.177.47:2381        //ase.product.collection=product        //ase.product.zkclienttimeout=2000000        //ase.product.zkconnectiontimeout=2000000        cloudSolrServer = new CloudSolrServer(PropertyUtil.getValue("ase.query.solrclient.url"));        cloudSolrServer.setDefaultCollection(PropertyUtil.getValue("ase.product.collection"));        cloudSolrServer.setZkClientTimeout(Integer.parseInt(PropertyUtil.getValue("ase.product.zkclienttimeout")));        cloudSolrServer.setZkConnectTimeout(Integer.parseInt(PropertyUtil.getValue("ase.product.zkconnectiontimeout")));    }    public static CloudSolrServer getCloudSolrServer(){        if( null == cloudSolrServer){            getInstance().initSolrClient();        }        return cloudSolrServer;    }}

SolrCloud调用：

SolrClientFactory.getInstance().initSolrClient();  //可以容器启动时候初始化//查询索引CloudSolrServer cloudSolrServer = SolrClientFactory.getCloudSolrServer();response = cloudSolrServer.query(sQuery);//添加索引Collection<SolrInputDocument> docs = new ArrayList<SolrInputDocument>();//......设置docs 的值CloudSolrServer cloudSolrServer = SolrClientFactory.getCloudSolrServer();cloudSolrServer.add(docs);cloudSolrServer.commit();

solr使用过程中发现的问题：

IK扩展词库中添加单词，做Analysis分析的时候完全正确，可以是就是查询不出索引记录，后来试验了一晚上。终于在一些大神的指导下，发现了问题的所以，词库添加扩展之后，一定要把之前创建的索引删除，重新创建索引。
