Spring Data Solr入门

　　如何将Solr的应用集成到Spring中?

SpringDataSolr就是为了方便Solr的开发所研制的一个框架,其底层是对SolrJ的封装.

SpringDataSolr入门小Demo

首先目录结构为:

搭建工程,需要引入的依赖为:

   <dependencies>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-solr</artifactId>
        <version>1.5.5.RELEASE</version>
    </dependency> 
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>
        <version>4.2.4.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.9</version>
    </dependency>
  </dependencies>
<build>
    <plugins>            
        <!-- java编译插件 -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.2</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <encoding>UTF-8</encoding>
            </configuration>
         </plugin>
</plugins>
</build>
</build>

如果jar包不完全引入,就会出现报错的情况的.

然后在Resource下创建的配置文件是:

<?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:solr="http://www.springframework.org/schema/data/solr"
    xsi:schemaLocation="http://www.springframework.org/schema/data/solr 
          http://www.springframework.org/schema/data/solr/spring-solr-1.0.xsd
        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">
    <!-- solr服务器地址 -->
    <solr:solr-server id="solrServer" url="http://192.168.200.128:8080/solr" />
    <!-- solr模板，使用solr模板可对索引库进行CRUD的操作 -->
    <bean id="solrTemplate" class="org.springframework.data.solr.core.SolrTemplate">
        <constructor-arg ref="solrServer" />
    </bean>
</beans>

http://192.168.200.128:8080   这是我在虚拟机中配置的tomcat,然后在虚拟机中配置的solr

如果属性和配置文件定义的域名不一致的时候,需要在注解中指定域名称.
这是我配置的pojo类
