最近做了个Java的小项目（第一次写Java的项目哦），到网上搜索了半天，找到了一个比较好点的调用存储过程的例子，而且网上普遍采用的都是setXXX((int parameterIndex,XXX x)的形式。这种形式感觉不是很直观，下面就发布一个完整的采用setXXX(String parameterName,XXX x)的编写方法。创建数据表，存储过程的代码都完整发布。
创建表：
CREATETABLE[BookUser](
[UserID][int]IDENTITY(1,1)NOTNULL,
[UserName][varchar](50)COLLATEChinese_PRC_CI_ASNOTNULL,
[Title][nvarchar](50)COLLATEChinese_PRC_CI_ASNOTNULL,
[Guid][uniqueidentifier]NOTNULLCONSTRAINT[DF_BookUser_Guid]DEFAULT(newid()),
[BirthDate][datetime]NOTNULL,
[Description][ntext]COLLATEChinese_PRC_CI_ASNOTNULL,
[Photo][image]NULL,
[Other][varchar](50)COLLATEChinese_PRC_CI_ASNULLCONSTRAINT[DF_BookUser_Other]DEFAULT('默认值'),
CONSTRAINT[PK_BookUser]PRIMARYKEYCLUSTERED
(
[UserID]
)ON[PRIMARY]
)ON[PRIMARY]TEXTIMAGE_ON[PRIMARY]
GO
创建存储过程：
CREATEPROCEDUREInsertUser
@UserNamevarchar(50),
@Titlevarchar(255),
@Guiduniqueidentifier,
@BirthDateDateTime,
@Descriptionntext,
@Photoimage,
@Othernvarchar(50),
@UserIDintoutput
As
SetNOCOUNTON
IfExists(selectUserIDfromBookUserWhereUserName=@UserName)
RETURN0
ELSE
Begin
INSERTINTOBookUser(UserName,Title,Guid,BirthDate,Description,Photo,Other)VALUES(@UserName,@Title,@Guid,@BirthDate,@Description,@Photo,@Other)
SET@UserID=@@IDENTITY
RETURN1
End
GO
JSP代码：

<%@pageimport="java.sql.*"%>

cmd=cn.prepareCall(sql);

DaterightNow=Date.valueOf("-9-9");
cmd.setString("UserName","mengxianhui"); //注意修改这里，存储过程验证了UserName的唯一性。
cmd.setString("Title","孟宪会");
cmd.setString("Guid",Guid.toString());
cmd.setString("BirthDate","-9-9");
cmd.setDate("BirthDate",rightNow);
cmd.setString("Description","【孟子E章】");
cmd.setBinaryStream("Photo",f,f.available());
cmd.setString("Other",null);
cmd.registerOutParameter(1,java.sql.Types.INTEGER);
cmd.registerOutParameter("UserID",java.sql.Types.INTEGER);
cmd.execute();
intreturnValue=cmd.getInt(1);
intUserID=cmd.getInt("UserID");
if(returnValue==1)
{
out.print("<li>添加成功！");
out.print("<li>UserID="+UserID);
out.print("<li>returnValue="+returnValue);
}
else
{
out.print("<li>添加失败！");
}
f.close();
}
catch(Exceptionex)
{
out.print(ex.getLocalizedMessage());
}
finally
{
try
{
if(cmd!=null)
{
cmd.close();
cmd=null;
}
if(cn!=null)
{
cn.close();
cn=null;
}
}
catch(Exceptione)

}
