本文将阐述如何把solr与spring集成。

1、前提约束

• 可以使用java调用solr的api https://www.jianshu.com/p/222ef7d58efc

2、修改pom.xml

在pom.xml中加入以下依赖：

        <dependency>
            <groupId>org.apache.solr</groupId>
            <artifactId>solr-solrj</artifactId>
            <version>4.10.3</version>
        </dependency>
        <dependency>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.2</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aspects</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jms</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>

3、在src/main/resources下加入applicationContext-solr.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd">
	<!-- 单机版solr的连接 -->
	<bean id="httpSolrServer" class="org.apache.solr.client.solrj.impl.HttpSolrServer">
		<constructor-arg name="baseURL" value="http://192.168.100.192:8080/solr/collection1"/>
	</bean>
</beans>

4、完成测试类

import org.apache.solr.client.solrj.SolrQuery;
import org.apache.solr.client.solrj.SolrServer;
import org.apache.solr.client.solrj.impl.HttpSolrServer;
import org.apache.solr.client.solrj.response.QueryResponse;
import org.apache.solr.common.SolrDocument;
import org.apache.solr.common.SolrDocumentList;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestSolrInSpring {

    public static void main(String[] args) throws Exception {

        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:applicationContext-solr.xml");

        // 第一步：创建一个SolrServer对象
        HttpSolrServer solrServer = (HttpSolrServer) applicationContext.getBean("httpSolrServer");
        // 第二步：创建一个SolrQuery对象。
        SolrQuery query = new SolrQuery();
        //  第三步：向SolrQuery中添加查询条件、过滤条件。。。
        query.setQuery("title:ali");
        // 第四步：执行查询。得到一个Response对象。
        QueryResponse response = solrServer.query(query);
        // 第五步：取查询结果。
        SolrDocumentList solrDocumentList = response.getResults();
        System.out.println("查询结果的总记录数：" + solrDocumentList.getNumFound());
        // 第六步：遍历结果并打印。
        for (SolrDocument solrDocument : solrDocumentList) {
            System.out.println(solrDocument.get("id"));
            System.out.println(solrDocument.get("title"));
        }
    }
}

执行，便能看到测试结果【前提是solr中有索引数据】。
