Java/JSP中调用SQL Server存储过程完整示例

2007-09-09 11:18 411 查看

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：

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：
[b]

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[/b]JSP代码：
[b]

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

<%@ page import = "java.sql.*"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

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();

    }

}
