java编程调用存储过程中得到新增记录id号的实现方法

CREATE PROCEDURE yh_insert
@yhm varchar(50),@kl varchar(50)
AS
begin
set nocount on
 insert into test(yhm,kl) values(@yhm,@kl)
set nocount off
select newid=@@identity
end
GO

declare @id int
exec sp_yh_insert 'tetstst','111111',@id output
select @id

CREATE PROCEDURE sp_yh_insert
@yhm varchar(50),@kl varchar(50),@id int output
AS
begin
set nocount on
 insert into test(yhm,kl) values(@yhm,@kl)
set nocount off
--select newid=@@identity
select @id=@@identity --关键
end
GO

public String call_sp_insert_jh(String yhm,String kl)throws Exception
{
  String strFlag = "";
  String strString = "";
  Connection conn = null;
  try
   {
    conn = db.getConnection();
    //CallableStatement proc = conn.prepareCall(strSql);
    CallableStatement  proc=conn.prepareCall("{call sp_yh_insert(?,?,?)}");
    proc.setString(1, "往往外饿饿饿额"); //给第一个输入参数赋值
    proc.setString(2, "1111111"); //给第2个输入参数赋值
    proc.registerOutParameter(3,Types.INTEGER); //处理输出参数
    proc.execute(); //执行sp
    int id = proc.getInt(3);//得到返回值的值
    strString=Integer.toString(id);
    strFlag=strString ;
   }
  catch (SQLException e)
   {
     System.out.println("proc execute error"+strString);
    }
  finally
   {
     //关闭数据库联接
     try
      {
      conn.close();
      }
     catch(Exception sqle)
      {
      //产生新 异常，则抛出新 程序异常
      //throw new Exception("[DBBean.executeQuery(sql,tname)]","10");
      System.out.println("出错了");
      }
    }
