Solr添加文档到索引

solr添加文档非常方便,不用像Lucene那样一个一个添加Field,省去了很多的麻烦下面看操作

方法一:

    private static String URI = "http://localhost:8080/solr/";

    private CommonsHttpSolrServer httpSolrServer = null;

    @Before
    public void init() {
        try {
            httpSolrServer = new CommonsHttpSolrServer(URI);
        } catch (MalformedURLException e) {
            e.printStackTrace();
        }
    }

    @Test
    public void test1() {
        try {
            SolrInputDocument document = new SolrInputDocument();
            document.addField("id", "1");
            document.addField("news_title", "这是我的第一个solr程序");
            document.addField("news_content", "希望能够运行起来");
            httpSolrServer.add(document);
            httpSolrServer.commit();
        } catch (SolrServerException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

Note:id为唯一,不可重复,如果重复,solr会自动将索引中id相同的元素更新为现在的属性
域的名称可以在schema.xml的Field中设置,默认的有很多Field,我们也可以使用默认的

   <field name="news_title" type="textComplex" indexed="true" stored="true" />
   <field name="news_content" type="textComplex" indexed="true" sotred="true" />

方法2:直接添加对象

2.1 定义对象

package com.solr.entity;

import org.apache.solr.client.solrj.beans.Field;

public class News {
    private String id;
    private String title;
    private String content;

    public News(){}
    
    public News(String id, String title, String content) {
        this.id = id;
        this.title = title;
        this.content = content;
    }

    public String getId() {
        return id;
    }

    @Field
    public void setId(String id) {
        this.id = id;
    }

    public String getTitle() {
        return title;
    }

    @Field("news_title")
    public void setTitle(String title) {
        this.title = title;
    }

    public String getContent() {
        return content;
    }

    @Field("news_content")
    public void setContent(String content) {
        this.content = content;
    }

}

2.2 添加对象到索引

    @Test
    public void test2() {
        try {
            List<News> list = new ArrayList<News>();
            News news1 = new News("2", "title2", "content2");
            list.add(news1);
            News news2 = new News("3", "title3", "content3");
            list.add(news2);

            httpSolrServer.addBeans(list);
            httpSolrServer.commit();
        } catch (SolrServerException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

Note:如果对象的某个域里面的属性为数组,我们需要在schema.xml的Field中设置 multiValued="true"
