使用 SolrJ 将文档添加到 Solr

如果我们有一个模式如下：

<field name="id" type="string" indexed="true" stored="true" required="true" /> 

<field name="name" type="string" indexed="true" stored="true" />

向 Solr 添加内容的 solrj 代码如下所示：

 package com.stackoverflow.solrj.example;

import java.io.IOException;
import java.util.ArrayList;
import java.util.Collection;

import org.apache.solr.client.solrj.SolrClient;
import org.apache.solr.client.solrj.SolrServerException;
import org.apache.solr.client.solrj.impl.HttpSolrClient;
import org.apache.solr.common.SolrInputDocument;

public class SolrJIndexing {

    private final static String SOLR_URL = "http://localhost:8983/solr/mycollection";

    public static void main(String[] args) {
        SolrClient solrClient = new HttpSolrClient.Builder(SOLR_URL).build();
        SolrInputDocument document1 = getDocument(1, "Document example 1");
        SolrInputDocument document2 = getDocument(2, "Document example 2");
        Collection<SolrInputDocument> docs = new ArrayList<SolrInputDocument>();
        docs.add(document1);
        docs.add(document2);
        try {
            solrClient.add(docs);
            solrClient.commit();
        } catch (SolrServerException | IOException e) {
            e.printStackTrace();
        }
    }

    private static SolrInputDocument getDocument(int id, String name) {
        SolrInputDocument document = new SolrInputDocument();
        document.addField("id", id);
        document.addField("name", name);
        return document;
    }

}
