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][Solr_SolrJ]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
