1.26、selectPage分页查询

内存分页RowBounds,并不是使用limit,不常用.一般借助分页插件分页

package com.wzy.text;
import com.baomidou.mybatisplus.plugins.Page;
import com.wzy.mapper.EmployeeMapper;
import com.wzy.pojo.Employee;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class TestS {
    ApplicationContext applicationContext =
            new ClassPathXmlApplicationContext("applicationContext.xml");
    EmployeeMapper employeeMapper =
            applicationContext.getBean("employeeMapper",EmployeeMapper.class);
    @Test
    public void test10() throws SQLException {
        //分页查询
        List<Employee> list = employeeMapper.selectPage(new Page<>(2, 2), null);
        list.forEach(employee -> System.out.println(employee));
    }
}
