推薦：如何在Struts 2中實(shí)現(xiàn)文件上傳
前一陣子有些朋友在電子郵件中問(wèn)關(guān)于Struts 2實(shí)現(xiàn)文件上傳的問(wèn)題，所以今天我們就來(lái)討論一下這個(gè)問(wèn)題。實(shí)現(xiàn)原理 Struts 2是通過(guò)Commons FileUpload文件上傳。Commons FileUpload通過(guò)將HTTP的數(shù)據(jù)保存到臨時(shí)文件夾，然后Struts使用fileUpload攔截器將文件綁

最近做了個(gè)Java的小項(xiàng)目（第一次寫(xiě)Java的項(xiàng)目哦），到網(wǎng)上搜索了半天，找到了一個(gè)比較好點(diǎn)的調(diào)用存儲(chǔ)過(guò)程的例子，而且網(wǎng)上普遍采用的都是setXXX((int parameterIndex, XXX x)的形式。這種形式感覺(jué)不是很直觀，下面就發(fā)布一個(gè)完整的采用setXXX(String parameterName, XXX x)的編寫(xiě)方法。創(chuàng)建數(shù)據(jù)表，存儲(chǔ)過(guò)程的代碼都完整發(fā)布。

創(chuàng)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 ('默認(rèn)值'),
CONSTRAINT [PK_BookUser] PRIMARY KEY CLUSTERED
(
[UserID]
) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

創(chuàng)建存儲(chǔ)過(guò)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代碼：
