solrj操纵CloudSolrServer的一般步骤

来源：互联网发布：相册软件哪个好编辑：程序博客网时间：2024/06/05 23:59

1. 创建CloudSolrServer的实例：2种方式：

(a) CloudSolrServer cloudSolrServer= new CloudSolrServer(zkHostURL);

(b) CloudSolrserver.cloudSolrServer = new CloudSolrServer(zkHostURL,lbHttpSolrServer);

2. 对CloudSolrServer实例进行设置

(a) cloudSolrServer.setDefaultCollection(defaultCollectionName);

(b) cloudSolrServer.setzkClientTimeout(zkClientTimeout);

3. 将cloudSolrServer实例连接到zookeeper

(a) cloudSolrServer.connect();

4. CloudSolrServer 的实例cloudSolrServer实例化、连接完成，进而可以对其进行add、query、delete操作。

(a) 建index：准备document,最好批量添加，有利于提高性能。添加文档的字段于solr中配置文件schema.xml有关，需要对其设置。

(b) 通过SolrQuery可以对cloudSolrServer实例进行各种查找操作。

5. 操作结束，关闭CloudSolrServer实例，以释放资源。

cloudSolrServer.shutdown();
