使用solrj進行solr查詢

1.構(gòu)建maven工程嘹履，使用spring boot 奖年，添加如下依賴

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.3.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
</parent>
<dependencies>
        <dependency>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-data-solr</artifactId>
        </dependency>
        <!-- 替換solrj為solr服務(wù)器的版本 -->
        <dependency>
              <groupId>org.apache.solr</groupId>
              <artifactId>solr-solrj</artifactId>

        </dependency>
</dependencies>
<build>
        <plugins>
            <plugin>

                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
 </build>

2.編寫查詢接口IIndexSearch

public interface IndexSearch {

    /**

     * @return
     * @throws Exception
     * @Title: search
     * @Description:
     * @return: PageData
     */
    ResultEntity search(String id);

    /**
     * @param query
     * @param isHight 是否高亮顯示
     * @return
     */
    ResultEntity execute(SolrQuery query, boolean isHight);

}
  • 接口ISolrIndexSearch
public interface ISolrIndexSearch extends IndexSearch {

    /**
     * 獲取SolrQuery對象
     *
     * @return
     */
    SolrQuery getQuery();

    /**
     * 查詢
     *
     * @param page    封裝分頁
     * @param query   查詢條件
     * @param isHight 是否高亮顯示
     * @return
     */
    ResultEntity search(Page page, SolrQuery query, boolean isHight);

}
  • 抽象實現(xiàn)類AbstractSolrIndexSearch
public abstract class AbstractSolrIndexSearch implements ISolrIndexSearch {

    private static final Logger LOGGER = Logger.getLogger(AbstractSolrIndexSearch.class);

    @Resource(name = "solrClient")
    protected SolrClient solr;

    public abstract SolrQuery setHighlightHandle(SolrQuery query);

    public abstract List<PageData> gethighlighDataList(SolrResponse response);

    private ResultEntity putResponseMessage(List<PageData> datas, int responseTime, Page page) {

}
  • 子類去實現(xiàn)抽象類中的的抽象方法SolrIndexSearch
public class SolrIndexSearch extends AbstractSolrIndexSearch {
    private static final Logger LOGGER = Logger.getLogger(SolrIndexSearch.class);

    @Override

        return null;
    }

    @Override
    public List<PageData> gethighlighDataList(SolrResponse response) {
        return null;
    }

}

3.編寫索引操作接口IndexeWriter

public interface IndexeWriter {

    ResultEntity delete(List<String> ids);

    ResultEntity delete(String id);

    void deleteAll() throws Exception;
    
    ResultEntity execute(SolrInputDocument document);

    private ISolrIndexSearch solrIndexSearch;

    @Resource(name = "solrIndexWriter")
    private IndexeWriter indexeWriter;

     * @throws Exception
     */

    }

    }

    }

     * @param query
     * @param isHight
     * @return
     * @throws Exception
     */
    public ResultEntity search(Page page, SolrQuery query, boolean isHight) throws Exception {
        return solrIndexSearch.search(page, query, isHight);
    }

}

5.在application.properties中配置solr

solr.url=http://host:port/solr/
solr.collection=collectionname
#是否為集群
solr.cluster=false
solr.timeout=10000
solr.maxconnection=100
solr.queuesize=20
#集群中必須配置zookeeper地址
solr.zookeeper.url=192.168.0.5:2181

6.配置solr系谐，在spring boot啟動中，覆蓋默認的solrClient配置

public class SolrConfig implements EnvironmentAware {

    private static Logger LOGGER = Logger.getLogger(SolrConfig.class);

    private boolean solrCluster = false;

    private SolrConfigBean config;

    @Override
    public void setEnvironment(Environment environment) {
        config = new SolrConfigBean();
        loadProperties(environment);
    }

    private void loadProperties(Environment env) {
        String url = env.getProperty("solr.url");
        int maxConnection = Integer.parseInt(env.getProperty("solr.maxconnection"));
        String collection = env.getProperty("solr.collection");
        int timeout = Integer.parseInt(env.getProperty("solr.timeout"));
        boolean solrIsCluster = Boolean.parseBoolean(env.getProperty("solr.cluster"));

        if (solrIsCluster) {
            String zookeeperUrl = env.getProperty("solr.zookeeper.url");
            if (zookeeperUrl.indexOf(",") != -1) {
                String[] tmp = zookeeperUrl.split(",");
                List<String> zkList = Lists.newArrayList(tmp);
                config.setZookeeperUrl(zkList);
            } else {
                List<String> zkList = Lists.newArrayList(zookeeperUrl);
                config.setZookeeperUrl(zkList);
            }
        }

        config.setTimeout(timeout);
        config.setUrl(url);
        config.setCollection(collection);
        config.setMaxConnection(maxConnection);
        solrCluster = solrIsCluster;

    }
