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 {

@Field
private String key1;
@Field
private String key2;
@Field
private 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;
}
}
}
