java 调用存储过程

最近做了个项目，是调用别人的存储过程。因为文档弄错了，害的我够惨。现在把调用java存储过程贴出来，希望大侠们多多指导。

Java代码







package test;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Timestamp;
import java.sql.Types;

public class hz {
public static
void main(String[] args )
{
CallableStatement proc = null;
Connection conn = null;
try
{
Class.forName("oracle.jdbc.driver.OracleDriver");

conn=DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:orcl","hz","oracle");

proc = conn.prepareCall("{call orcl.hz(?,?,?,?,?,?,?,?,?,?,?,?)}");

proc.setString(1,"ss");

proc.setInt(2,100);
//此时间格式必须传入时分秒
proc.setTimestamp(3,Timestamp.valueOf("2012-12-20 00:00:00"));

proc.setTimestamp(4,Timestamp.valueOf("2012-12-20 00:00:00"));

proc.setTimestamp(5,Timestamp.valueOf("2012-12-20 00:00:00"));

proc.setInt(6,1);
proc.setString(7,"aa");

proc.setString(8,"1");

proc.setString(9,"dd");

proc.setString(10,"bb");

//调用存储过程出参
proc.registerOutParameter(11,Types.Integer);
proc.registerOutParameter(12,Types.VARCHAR);
proc.execute();
//接受存储过程出参
int i = proc.getString(11);

String s = proc.getString(12);
System.out.println("i的值为："+i);
System.out.println("s的值为："+s);
}catch (Exception ex)
{
System.out.println(ex.getMessage());
}
}
