SolrUtils.java中代码

package com.apricotforest.doctor.pocket.solrsearch.util;

import org.apache.solr.client.solrj.impl.BinaryRequestWriter;
import org.apache.solr.client.solrj.impl.HttpSolrClient;

public class SolrUtils 
private String solrServer;
private static SolrUtils solrUtils;

public static HttpSolrClient getHttpSolrClient() 
    HttpSolrClient httpSolrClient = new HttpSolrClient(solrUtils.solrServer);
    httpSolrClient.setSoTimeout(10000);
    httpSolrClient.setConnectionTimeout(5000);
    httpSolrClient.setDefaultMaxConnectionsPerHost(1000);
    httpSolrClient.setMaxTotalConnections(1000);
    httpSolrClient.setFollowRedirects(false);
    httpSolrClient.setAllowCompression(true);
    httpSolrClient.setRequestWriter(new BinaryRequestWriter());
    return httpSolrClient;



public void init() 
    solrUtils = this;
    solrUtils.solrServer = this.solrServer;


public void setSolrServer(String solrServer) 
    this.solrServer = solrServer;
