mybatis-plus 分页

• applicationContext.xml

  <bean id="sqlSessionFactory" class="com.baomidou.mybatisplus.spring.MybatisSqlSessionFactoryBean">
  <property name="dataSource" ref="dataSource"/>
  <property name="configLocation" value="classpath:mybatis.xml"/>
  <property name="plugins">
    <list>
      <bean class="com.baomidou.mybatisplus.plugins.PaginationInterceptor"/>
    </list>
  </property>
  <property name="globalConfig" ref="globalConfiguration"/>
  </bean>

• 常用api ```java public void testPage() {

    Page<Employee> page = new Page<>(1,1);
    List<Employee > emps = 
            employeeMapper.selectPage(page, null);
    System.out.println(emps);

    System.out.println("===============获取分页相关的一些信息======================");
    System.out.println("总条数:" +page.getTotal());
    System.out.println("当前页码: "+  page.getCurrent());
    System.out.println("总页码:" + page.getPages());
    System.out.println("每页显示的条数:" + page.getSize());
    System.out.println("是否有上一页: " + page.hasPrevious());
    System.out.println("是否有下一页: " + page.hasNext());
    //将查询的结果封装到page对象中
    page.setRecords(emps);
}

```
