java中编辑调用数据库方法：返回为list

public ArrayList<TestResult> getResult() throws SQLException {
TestResult ts = new TestResult();
Config config = new Config();
DBTABLE =config.getSqltable();
ArrayList<TestResult> ls = new ArrayList<TestResult>();
Connection conn = getConnection();
Statement stmt = null; // 数据库的操作对象
ResultSet rs = null; // 保存查询结果
String sql = "SELECT id,proName,result,time FROM " + DBTABLE;
stmt = conn.createStatement();
rs = stmt.executeQuery(sql);
while (rs.next()) { // 依次取出数据
int id = rs.getInt(1); // 取出id列的内容
String proName = rs.getString(2); // 取出proName列的内容
String result = rs.getString(3); // 取出result列的内容
Date time = rs.getDate(4); // 取出time列的内容

ts.setId(id);
ts.setProName(proName);
ts.setResult(result);
ts.setTime(time.toString());

}

ls.add(ts);
rs.close();
stmt.close();
conn.close();
return ls;
}
