请问，这样是不是每循环一下都会创建新的Connection和Statement对象？conn和stmt在close之后是否还占用资源？用sleep暂停程序有没有问题？
for (;;){
try{
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@10.10.10.10:1394:test","admin","pass");
Statement stmt = conn.createStatement();
stmt.executeQuery("update testtable set scantime='"+systimes+"' where id = 'my'");]
stmt.close();
conn.close();
} catch(SQLException e){
e.printStackTrace();
}
try{
Thread.currentThread().sleep(60000);
}catch(InterruptedException ex){
ex.printStackTrace();
}
}
