分页-工具包（github.pagehelper）

pom.xml

<dependency>
		  <groupId>com.github.pagehelper</groupId>
		  <artifactId>pagehelper</artifactId>
		  <version>5.1.2</version>
</dependency>

代码：

• (一定要把PageHelper.startPage(page, rows)放在查询语句前面)
• page默认值是1，pageSize默认是10
• PageHelper是通过切面动态在查询sql中追加统计信息及分页信息来进行分页，而不是查询所有再手动分页的
