java连接solr并建立索引

1、在tomcat上配置solr：（以后补充）

2、新建一个实体类@Field下面的key要与solr对应索引目录的配置文件schema中的key相对应，代码demo如下，其中构造函数只是方便整体赋值：

package com.vo;import org.apache.solr.client.solrj.beans.Field;public class ClassName {@Fieldprivate String key1;@Fieldprivate String key2;@Fieldprivate String key3;public ClassName(String key1) {super();this.key1 = key1;}public String getkey1() {return key1;}public void setkey1(String key1) {this.key1 = key1;}public String getkey2() {return key2;}public void setkey2(String key2) {this.key2 = key2;}public String getkey3() {return key3;}public void setkey3(String key3) {this.key3 = key3;}

3、连接solr：

import org.apache.solr.client.solrj.SolrServer;import org.apache.solr.client.solrj.impl.HttpSolrServer;public class SolrContext {private static String url_video;private static String url_picture;private static String url_videoUpload;private static HttpSolrServer server_video;private static HttpSolrServer server_picture;private static HttpSolrServer server_videoUpload;static{url_video = PropertiesUtil.getValueByKey("storage.solr.url.video");url_picture = PropertiesUtil.getValueByKey("storage.solr.url.picture");url_videoUpload = PropertiesUtil.getValueByKey("storage.solr.url.videoupload");}private SolrContext() {}public static SolrServer getVideoServer() throws Exception{if(server_video==null){synchronized(SolrContext.class){if(server_video==null){server_video=new HttpSolrServer(url_video);server_video.setConnectionTimeout(5000);//solr连接超时时间server_video.setSoTimeout(5000);//solr查询超时时间server_video.setMaxTotalConnections(100);//solr所有最大连接数server_video.setDefaultMaxConnectionsPerHost(100);//solr最大连接数server_video.setAllowCompression(false);//solr是否允许压缩server_video.setMaxRetries(1);//solr最大重试次数server_video.setFollowRedirects(true);}}}return server_video;}public static SolrServer getPictureServer() throws Exception{if(server_picture==null){synchronized(SolrContext.class){if(server_picture==null){server_picture=new HttpSolrServer(url_picture);server_picture.setConnectionTimeout(5000);//solr连接超时时间server_picture.setSoTimeout(5000);//solr查询超时时间server_picture.setMaxTotalConnections(100);//solr所有最大连接数server_picture.setDefaultMaxConnectionsPerHost(100);//solr最大连接数server_picture.setAllowCompression(false);//solr是否允许压缩server_picture.setMaxRetries(1);//solr最大重试次数server_picture.setFollowRedirects(true);}}}return server_picture;}public static SolrServer getVideoUploadServer() throws Exception{if(server_videoUpload==null){synchronized(SolrContext.class){if(server_videoUpload==null){server_videoUpload=new HttpSolrServer(url_videoUpload);server_videoUpload.setConnectionTimeout(5000);//solr连接超时时间server_videoUpload.setSoTimeout(5000);//solr查询超时时间server_videoUpload.setMaxTotalConnections(100);//solr所有最大连接数server_videoUpload.setDefaultMaxConnectionsPerHost(100);//solr最大连接数server_videoUpload.setAllowCompression(false);//solr是否允许压缩server_videoUpload.setMaxRetries(1);//solr最大重试次数server_videoUpload.setFollowRedirects(true);}}}return server_videoUpload;}}

4、建立索引，其中UUID码是起到独特的标识作用，不用也行：

import java.util.UUID;import org.apache.log4j.Logger;import com.eshore.storage.utils.SolrContext;import com.eshore.storage.vo.VideoUpload;public class VideoUploadServiceImpl {private static final Logger log = Logger.getLogger(VideoUploadServiceImpl.class);public boolean generateIndex() {try {VideoUpload field = new VideoUpload(UUID.randomUUID().toString().replaceAll("-", ""));field.setVideo_id("1");field.setVideo_unique("1");field.setVideo_name("1");field.setStatus("1");field.setVideo_desc("1");field.setTag("1");field.setIs_pay("1");field.setImg("1");field.setVideo_duration("1");field.setInitial_size("1");field.setError_desc("1");field.setAdd_time("1");field.setComplete_time("1");SolrContext.getVideoUploadServer().addBean(field);SolrContext.getVideoUploadServer().commit();System.out.println("success!");return true;} catch (Exception e) {log.error("生成索引失败>>>>>>>>>>>", e);return false;}}}
