JSP中调用SQL Server存储过程完整示例

最近做了个Java的小项目，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：

CREATE TABLE [BookUser] (
    [UserID] [int] IDENTITY (1, 1) NOT NULL ,
    [UserName] [varchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL ,
    [Title] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL ,
    [Guid] [uniqueidentifier] NOT NULL CONSTRAINT [DF_BookUser_Guid] DEFAULT (newid()),
    [BirthDate] [datetime] NOT NULL ,
    [Description] [ntext] COLLATE Chinese_PRC_CI_AS NOT NULL ,
    [Photo] [image] NULL ,
    [Other] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_BookUser_Other] DEFAULT (默认值),
    CONSTRAINT [PK_BookUser] PRIMARY KEY CLUSTERED
    (
        [UserID]
    ) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

创建存储过程：

CREATE PROCEDURE InsertUser
@UserName varchar(50),
@Title varchar(255),
@Guid uniqueidentifier,
@BirthDate DateTime,
@Description ntext,
@Photo image,
@Other nvarchar(50),
@UserID int output
As
Set NOCOUNT ON
If Exists (select UserID from BookUser Where UserName = @UserName)
RETURN 0
ELSE
Begin
INSERT INTO BookUser (UserName,Title,Guid,BirthDate,Description,Photo,Other) VALUES(@UserName,@Title,@Guid,@BirthDate,@Description,@Photo,@Other)
SET @UserID = @@IDENTITY
RETURN 1
End
GO

JSP代码：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ page import = "java.sql.*"%>

String url="jdbc:sqlserver://localhost:1433;databaseName=Book;user=sa;password=";
String sql = "{? = call InsertUser(?,?,?,?,?,?,?,?)}";
Connection cn = null;
CallableStatement cmd = null;
try
{
    cn = DriverManager.getConnection(url);
    cmd = cn.prepareCall(sql);
    java.util.UUID Guid = java.util.UUID.randomUUID();
    String FilePath = application.getRealPath("") + " estlogo.gif";
    java.io.FileInputStream f = new java.io.FileInputStream(FilePath);
    Date rightNow = Date.valueOf("2007-9-9");
    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","2007-9-9");
    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();
    int returnValue = cmd.getInt(1);
    int UserID = 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(Exception ex)
{
    out.print(ex.getLocalizedMessage());
}
finally
{
    try
    {
        if(cmd != null)
        {
            cmd.close();
            cmd = null;
        }
        if(cn != null)
        {
            cn.close();
            cn = null;
        }
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }
}
