本文实例讲述了java实现将结果集封装到List中的方法。分享给大家供大家参考，具体如下：

import java.sql.Connection; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Statement; import java.util.ArrayList; import java.util.List; public class TestResultSet { public static List query(){ Connection conn = new ConnectionUtil().openConnection(); try { Statement stmt = conn.createStatement(); String sql = "select id,name,email from customertbl"; ResultSet rs = stmt.executeQuery(sql); //将结果集封装到List中 List list = new ArrayList(); while(rs.next()){ // 可以根据列名称也可以根据列索引 int id = rs.getInt(1); String name = rs.getString("name"); String email = rs.getString("email"); System.out.println(id+":"+name+":"+email); Customer c = new Customer(); c.setId(id); c.setName(name); c.setEmail(email); //将对象存放到list容器中 list.add(c); } return list; } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); }finally{ try { conn.close(); } catch (SQLException e) { conn = null; e.printStackTrace(); } } return null; } }

希望本文所述对大家java程序设计有所帮助。
