搜索学习--Solr全文搜索服务器的基本使用（二）——Spring Data Solr的使用

在上一篇搜索学习–Solr全文搜索服务器的基本使用（一）——SolrJ的使用中，我是直接使用的SolrJ来调用Solr服务器的，而对于熟悉Spring Data系列的同学一定更希望用这种规范的方式去操作它。Spring Data是支持Solr的，只需要简单的配置，我们即可像操作数据库一样操作它。

测试使用

package top.yuyufeng.learn.lucene.solr;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import org.springframework.data.solr.core.query.result.HighlightEntry;
import org.springframework.data.solr.core.query.result.HighlightPage;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * @author yuyufeng
 * @date 2017/12/6
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring-solr.xml"})
public class BlogCoreTest {
    @Autowired
    private BlogCoreRepository blogCoreRepository;

    @Test
    public void testFindByKeywords() {
        Pageable pageable = new PageRequest(0, 10);
        HighlightPage<BlogCore> highlightPage = blogCoreRepository.findByKeywords("达摩院", pageable);
        for (int i = 0; i < highlightPage.getHighlighted().size(); i++) {
            BlogCore blogCore = highlightPage.getHighlighted().get(i).getEntity();
            for (HighlightEntry.Highlight highlight : highlightPage.getHighlighted().get(i).getHighlights()) {
                if ("blogTitle".equals(highlight.getField().getName())) {
                    blogCore.setBlogTitle(highlight.getSnipplets().get(0));
                } else if ("blogContent".equals(highlight.getField().getName())) {
                    blogCore.setBlogContent(highlight.getSnipplets().get(0));
                }
            }
            System.out.println(blogCore);
        }
    }

}

运行结果：

BlogCore{blogId=2, blogTitle=’达摩院超越业界龙头’, blogContent=’达摩院一定也必须要超越英特尔，必须超越微软，必须超越IBM，因为我们生于二十一世纪，我们是有机会后发优势的。’, createTime=Wed Dec 06 13:38:12 CST 2017, keywords=’null’}
BlogCore{blogId=1, blogTitle=’马云表达愿景’, blogContent=’10月11日杭州云栖大会上，马云表达了对新建成的阿里巴巴全球研究院—阿里巴巴达摩院的愿景，希望达摩院二十年内成为世界第一大经济体，服务世界二十亿人，创造一亿个工作岗位。’, createTime=Wed Dec 06 12:03:56 CST 2017, keywords=’null’}

备注

之前已经建立索引，这里就直接搜索keywords了
