solr配置与solrj EmbeddedSolrServer使用篇

Solr的配置网上讲的很多，但是实施总是遇到困难，现总结如下

1.从官网下载solr core的源码包，将solrwar包放到tomcat的webapps文件夹下，其它web容器亦然.

    运行tomcat ,解压出来solr的文件夹.

2.Single core配置：以solr自带例子做讲解

2.1.新建solrhome目录:d:/test/solrcore/singlecore ,从solr源码的example包下复制solr包

        2.2.在tomcat 下的 webappss的solr包 WEB-INF目录下修改web.xml的 

<env-entry-name>solr/home</env-entry-name>

<env-entry-value> D:/test/solrcore/singlecore</env-entry-value>

                <env-entry-type>java.lang.String</env-entry-type>

        2.3.修改solrhome目录下的solr下的conf的solrconfig.xml文件

                <dataDir>D:/test/solrcore/data/singlecore</dataDir>

              此目录放置的是solr的data索引文件

        2.4.启动solr控制台，即可

 

3.multicore 配置：以solr core源码的multicore为例

        3.1. 新建solrhome目录:d:/test/solrcore/multicore从solr源码的example下复制multicore目录到在solrhome下

        3.2.  在tomcat 下的 webappss的solr包 WEB-INF目录下修改web.xml的 

                <env-entry-name>solr/home</env-entry-name>

                <env-entry-value> D:/test/solrcore/multicore</env-entry-value>

                <env-entry-type>java.lang.String</env-entry-type>

        3.2.  修改solrhome目录下的solr下的conf的solrconfig.xml文件            

                <dataDir>D:/test/solrcore/data/multicore</dataDir>
        3.3. 将core0和core1的索引文件放到 D:/test/solrcore/data/multicore目录下

        3.4. 启动solr控制台，可以看到二个core，安装完成

 

 

 

 

4.EmbeddedSolrServer使用

        4.1:singleCore使用：

package com.taobao.terminator.allen.SolrjTest;import org.apache.solr.client.solrj.SolrQuery;import org.apache.solr.client.solrj.embedded.EmbeddedSolrServer;import org.apache.solr.common.SolrDocument;import org.apache.solr.common.SolrDocumentList;import org.apache.solr.common.SolrInputDocument;import org.apache.solr.core.CoreContainer;import org.junit.Test;public class EmbedSolrServerSingleCoreTest {private static CoreContainer.Initializer initializer = null;private static CoreContainer coreContainer = null;private static EmbeddedSolrServer server = null;static {try {System.setProperty("solr.solr.home", "D://test//solrcore//core0");initializer = new CoreContainer.Initializer();coreContainer = initializer.initialize();server = new EmbeddedSolrServer(coreContainer, "");} catch (Exception e) {e.printStackTrace();}}@Testpublic void query() throws Exception {try {SolrQuery q = new SolrQuery();q.setQuery("*:*");q.setStart(0);q.setRows(20);SolrDocumentList list = server.query(q).getResults();System.out.println(list.getNumFound());} catch (Exception e) {e.printStackTrace();} finally {coreContainer.shutdown();}}@Testpublic void deleteAllDoc() throws Exception {try {server.deleteByQuery("*:*");server.commit();query();} catch (Exception e) {e.printStackTrace();} finally {coreContainer.shutdown();}}}

        4.2：multiCore使用：

                package com.taobao.terminator.allen.SolrjTest;import java.io.File;import org.apache.solr.client.solrj.SolrQuery;import org.apache.solr.client.solrj.embedded.EmbeddedSolrServer;import org.apache.solr.core.CoreContainer;import org.apache.solr.core.CoreContainer.Initializer;public class EmbedSolrServerMultiCoreTest {private static CoreContainer.Initializer initializer = null;private static CoreContainer coreContainer = null;private static EmbeddedSolrServer server = null;static {try {System.setProperty("solr.solr.home", "D://test//solrcore//core1");initializer = new CoreContainer.Initializer();coreContainer = initializer.initialize();server = new EmbeddedSolrServer(coreContainer, "");} catch (Exception e) {e.printStackTrace();}}public void query() throws Exception {try {File f = new File( "D:/test/solrcore/multicore", "solr.xml" );coreContainer = new Initializer().initialize();coreContainer.load("D:/test/multicore", f);coreContainer.setPersistent(true);server = new EmbeddedSolrServer(coreContainer, "core1");SolrQuery q = new SolrQuery();q.setQuery("*:*");System.out.println(server.query(q).getResults().getNumFound());} catch (Exception e) {e.printStackTrace();} finally {coreContainer.shutdown();}}}
