實現(xiàn)代碼
1、配置pom，在maven添加solr的依賴

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

配置如下內(nèi)容：

配置要連接的solrcore

applicationContext.xml的代碼如下：

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"xmlns:task="http://www.springframework.org/schema/task"xmlns:mongo="http://www.springframework.org/schema/data/mongo" xsi:schemaLocation=" http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsdhttp://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-4.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsdhttp://www.springframework.org/schema/data/mongohttp://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd"><!-- 打開注解 --><context:annotation-config /><!-- <aop:aspectj-autoproxy/> --><!-- 打開自動掃描 --><context:component-scan base-package="cn.com.hbny.docdetection" /><!-- 定時器驅(qū)動 --><task:annotation-driven/><!-- 引入jdbc配置文件 --><context:property-placeholder location="classpath:jdbc.properties,classpath:mongodb.properties,classpath:solr.properties" /><!-- 配置solr服務(wù)器的地址 --><bean class="org.apache.solr.client.solrj.impl.HttpSolrServer"><constructor-arg value="${solr.host}"></constructor-arg></bean></beans>

DocInfoSolrService代碼實現(xiàn)：

package cn.com.hbny.docdetection.solr;import cn.com.hbny.docdetection.solr.po.ResultModel;public interface DocInfoSolrService {/*** 通過命名空間，檢測庫Id,文檔內(nèi)容,查找符合條件的元素* @param isPreciseSearch :是否是精確查找 true表示的是精確查找，false表示的是粗略查找* @param ns :報名* @param propertyId :屬性分類的* @param propertyType :屬性分類名稱* @param majorId :專業(yè)的id* @param title :標題* @param keyword :關(guān)鍵詞* @param sentences :句子內(nèi)容* @param pageNum :頁碼數(shù)* @param pageSize :每頁的大小* @return* @attention 方法的使用注意事項 * @author toto* @date 2017年4月4日 * @note begin modify by 涂作權(quán) 2017年4月4日 原始創(chuàng)建*/public ResultModel findDocInfoBySolr(Boolean isPreciseSearch,String ns,String propertyId,String propertyType,String majorId,String title,String keyword,String sentences,Integer pageNum,Integer pageSize); }
