最基本的分页查询

package PagingQuery;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class testPaging {
	public static void main(String[] args) {
		
		list(10, 5);
	}
	
	public static void list(int start, int count) {
		
		try {
			Class.forName("com.mysql.jdbc.Driver");
		} catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		try (
			Connection c = DriverManager.getConnection(
					"jdbc:mysql://127.0.0.1:3306/Hero?characterEncoding=UTF-8",
					"root",
					"123");
			Statement s = c.createStatement();
			)
		{	//limit 0,5  表示第0条数据开始查询五条包括第0条数据
			String sql = "select * from user limit "+start+","+count;
			ResultSet rs = s.executeQuery(sql);
			
			while(rs.next()) {
				int i = rs.getInt("id");
				String name = rs.getString("name");
				System.out.printf("%d : %s%n",i,name);
			}
	} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
