1. 下载solr4.0_src的源码包,解压后,进入目录中,
在命令行执行:ant eclipse 则可以生成一个eclipse工程,会在目录中多了关于eclipse工程的文件:.classpath 和 .project;
在eclipse导入该生成的工程(lucene-solr),工程名为lucene-solr,可以看到其全部源码;
编写自己的代码,就能测试了!
注意:需要安装ant 工具,以及ivy包,搜一下,去appache下来,配置好,才能编译通过。Ant编译时间有点长。关于ant(another neat tool)不再过多介绍,网上有很多教程。只要明白 ant相当于一个make的工具,其解析biuld.xml文件的相关指令。
2. 下载solr4.0 zip 包,将其中的所有jar包都添加你的eclipse工程中。(之所以是所有,以防万一编译不过,省的猜缺少那个包,找呀找的!)
3. 结合网上关于solr的搭建教程,进行搭建solr,可以用tomcat,也可以用jetty。
我用的jetty+zookeeper,(由于对tomcat的集群配置不了解),
zookeeper是独立的zookeeper,而不是jetty内嵌的zookeeper;可以从appache上直接下载!
4. 进行相关集群的配置,配置集群,用在工程中用solrj操纵solrCloud
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);
(c) cloudSolrServer.setzkConnectTimeout(zkConnectionTimeout);
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。
(c) Delete操作可以通过id、Query的结果进行delete。
5. 操作结束,关闭CloudSolrServer实例,以释放资源。
cloudSolrServer.shutdown();
实例代码如下:

TestCloudSolr test = new TestCloudSolr(); System.out.println("测试添加index!!!"); //添加index test.addIndex(cloudSolrServer); System.out.println("测试查询query!!!!"); test.search(cloudSolrServer, "id:*"); System.out.println("测试删除!!!!"); test.deleteAllIndex(cloudSolrServer); System.out.println("删除所有文档后的查询结果:"); test.search(cloudSolrServer, "*:*"); // release the resource cloudSolrServer.shutdown(); } }
