jdbc调用存储过程-oracle版 返回游标

create or replace procedure getLog(record_ref out sys_refcursor,inputId in log201112.id%type)
AS
begin
open record_ref for
select * from log201112 where id=inputId;
end getLog;
/

String procedure="{call getLog(?,?)}";
CallableStatement cstmt=conn.prepareCall(procedure);//conn为java.sql.Connection对象
cstmt.registerOutParameter(1, OracleTypes.CURSOR);//oracle驱动包里的类 import oracle.jdbc.OracleTypes;
cstmt.setInt(2, 2);
cstmt.execute();
ResultSet rs=(ResultSet)cstmt.getObject(1);
while(rs.next()){
String info=""+rs.getInt("ID");
info+=rs.getTimestamp("CREATE_TIME");
System.out.println(info);
