项目中经常用到全国省市区的数据表，但是这个是数据又会经常变动，每次都需要找最新的数据，很麻烦，特此记录一下，用jsoup爬取国家统计局的数据。
1.引入jar包
<dependency>
<groupId>org.jsoup</groupId>
<artifactId>jsoup</artifactId>
<version>1.7.3</version>
</dependency>
2.创建数据表，生成Haha实体类
DROP TABLE IF EXISTS `haha`;
CREATE TABLE `haha` (
`id` int NOT NULL AUTO_INCREMENT,
`code` bigint DEFAULT NULL,
`name` varchar(255) NOT NULL,
`parent_id` int NOT NULL DEFAULT '0',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3647 DEFAULT CHARSET=utf8;
3.实现接口
//省份代码json
