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：

28. q.setStart(0);

38. }
39. }
40. @Test

46. }catch(Exceptione){
47. e.printStackTrace();
48. }finally{
49. coreContainer.shutdown();
50. }
51. }
53. }

4.2：multiCore使用：

14. initializer=newCoreContainer.Initializer();
15. coreContainer=initializer.initialize();
16. server=newEmbeddedSolrServer(coreContainer,"");
17. }catch(Exceptione){
18. e.printStackTrace();
19. }
20. }
22. publicvoidquery()throwsException{
23. try{
24. Filef=newFile("D:/test/solrcore/multicore","solr.xml");
25. coreContainer=newInitializer().initialize();
26. coreContainer.load("D:/test/multicore",f);
27. coreContainer.setPersistent(true);
29. server=newEmbeddedSolrServer(coreContainer,"core1");
30. SolrQueryq=newSolrQuery();
31. q.setQuery("*:*");
33. System.out.println(server.query(q).getResults().getNumFound());
34. }catch(Exceptione){
