通过JDBC取Oracle数据库的时间字段时，时间丢失，只剩日期

 1 try {
 2     Class.forName("oracle.jdbc.OracleDriver");
 3     Properties prop=new Properties();
 4     prop.setProperty("user","数据库用户");
 5         prop.setProperty("password","数据库密码");
 6         prop.setProperty("oracle.jdbc.V8Compatible","true");
 7     cOnn= DriverManager.getConnection("数据库地址",prop);
 8 } catch (ClassNotFoundException e) {
 9     e.printStackTrace();
10 } catch (SQLException e) {
11     e.printStackTrace();
12 }
