solr初次使用

1.引入jar包

<dependencies> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> </dependency> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-solr</artifactId> <version>1.5.5.RELEASE</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> </dependency> <dependency> <groupId>com.github.promeg</groupId> <artifactId>tinypinyin</artifactId> <version>2.0.3</version> </dependency> <dependency> <groupId>com.offcn</groupId> <artifactId>dongyimai_dao</artifactId> <version>1.0</version> </dependency> <!--转汉语拼音--> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> </dependency> <dependency> <groupId>com.github.promeg</groupId> <artifactId>tinypinyin</artifactId> <version>2.0.3</version> </dependency> </dependencies>

2.配置xml文件

<?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:context="http://www.springframework.org/schema/context" xmlns:solr="http://www.springframework.org/schema/data/solr" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/data/solr http://www.springframework.org/schema/data/solr/spring-solr.xsd"> <context:component-scan base-package="com.offcn.util"/> <!--配置solr的连接--> <solr:solr-server url="http://192.168.188.128:8983/solr/collection1" id="solrServer"/> <!--声明solrTemplate--> <bean class="org.springframework.data.solr.core.SolrTemplate" id="solrTemplate"> <constructor-arg ref="solrServer"/> </bean> </beans>

3.demo展示
