第三章solrj客户端使用demo

根据第二章完成的基础进行。

表结构如下

-- 表结构sql如下        SET FOREIGN_KEY_CHECKS=0;-- Table structure for studentDROP TABLE IF EXISTS student;CREATE TABLE student (sid bigint(20) NOT NULL,sname varchar(255) DEFAULT NULL,sage int(11) DEFAULT NULL,saddress varchar(255) DEFAULT NULL,sdescript text,PRIMARY KEY (sid)) ENGINE=InnoDB DEFAULT CHARSET=utf8;-- Records of studentINSERT INTO student VALUES ('1', '李四', '23', '中华路1号', '好学生');INSERT INTO student VALUES ('2', '张三', '34', '华信路3号', '坏学生，经常做坏事！');

maven中使用的jar版本参考如下

<dependency>            <groupId>org.apache.solr</groupId>            <artifactId>solr-solrj</artifactId>            <version>5.3.1</version>        </dependency>         <!-- solr包 依赖commons-logging-->         <dependency>            <groupId>commons-logging</groupId>            <artifactId>commons-logging</artifactId>            <version>1.1</version>    </dependency>
