我的一个程序中的示例：

程序声明

create procedure countLeftChildren(in parent_id int,out RightChildren int)...

调用代码

            String call = "{call countLeftChildren(?,?)}";
            CallableStatement callableStatement = connection.prepareCall(call);
            callableStatement.setInt(1, u.getIdsoftuser());
            callableStatement.registerOutParameter(2, java.sql.Types.INTEGER);
            callableStatement.executeUpdate();
            int children = callableStatement.getInt(2);

registerOutParameter (index,type) - index : 在过程声明中声明变量的编号（创建代码）。在上面的例子中，它是第二个变量。

您的代码是错误的，因为在您的过程声明中没有定义 OUT 参数

cstmt.registerOutParameter(2, Types.INTEGER); 

create procedure school_dmo.stud(in bk_cd char(10)) - Only one parameter and that 
is a IN parameter

另一个非常好的例子。
