|
* A component for handling HTML file uploads as specified by |
||||||
|
* <a href="http://www.ietf.org/rfc/rfc1867.txt" target="_top">RFC 1867</a>. |
||||||
|
* This component provides support for uploads within both servlets (JSR 53) |
||||||
|
* and portlets (JSR 168). |
||||||
|
* </p> |
||||||
|
* <p> |
||||||
|
* While this package provides the generic functionality for file uploads, |
||||||
|
* these classes are not typically used directly. Instead, normal usage |
||||||
|
* involves one of the provided extensions of |
||||||
|
* {@link com.fr.third.org.apache.commons.fileupload.FileUpload FileUpload} such as |
||||||
|
* {@link com.fr.third.org.apache.commons.fileupload.servlet.ServletFileUpload ServletFileUpload} |
||||||
|
* or |
||||||
|
* {@link com.fr.third.org.apache.commons.fileupload.portlet.PortletFileUpload PortletFileUpload}, |
||||||
|
* together with a factory for |
||||||
|
* {@link com.fr.third.org.apache.commons.fileupload.FileItem FileItem} instances, |
||||||
|
* such as |
||||||
|
* {@link com.fr.third.org.apache.commons.fileupload.disk.DiskFileItemFactory DiskFileItemFactory}. |
||||||
|
* </p> |
||||||
|
* <p> |
||||||
|
* The following is a brief example of typical usage in a servlet, storing |
||||||
|
* the uploaded files on disk. |
||||||
|
* </p> |
||||||
|
* <pre>public void doPost(HttpServletRequest req, HttpServletResponse res) { |
||||||
|
* DiskFileItemFactory factory = new DiskFileItemFactory(); |
||||||
|
* // maximum size that will be stored in memory
|
||||||
|
* factory.setSizeThreshold(4096); |
||||||
|
* // the location for saving data that is larger than getSizeThreshold()
|
||||||
|
* factory.setRepository(new File("/tmp")); |
||||||
|
* |
||||||
|
* ServletFileUpload upload = new ServletFileUpload(factory); |
||||||
|
* // maximum size before a FileUploadException will be thrown
|
||||||
|
* upload.setSizeMax(1000000); |
||||||
|
* |
||||||
|
* List fileItems = upload.parseRequest(req); |
||||||
|
* // assume we know there are two files. The first file is a small
|
||||||
|
* // text file, the second is unknown and is written to a file on
|
||||||
|
* // the server
|
||||||
|
* Iterator i = fileItems.iterator(); |
||||||
|
* String comment = ((FileItem)i.next()).getString(); |
||||||
|
* FileItem fi = (FileItem)i.next(); |
||||||
|
* // filename on the client
|
||||||
|
* String fileName = fi.getName(); |
||||||
|
* // save comment and filename to database
|
||||||
|
* ... |
||||||
|
* // write the file
|
||||||
|
* fi.write(new File("/www/uploads/", fileName)); |
||||||
|
* } |
||||||
|
* </pre> |
||||||
|
* <p> |
||||||
|
* In the example above, the first file is loaded into memory as a |
||||||
|
* <code>String</code>. Before calling the <code>getString</code> method, |
||||||
|
* the data may have been in memory or on disk depending on its size. The |
||||||
|
* second file we assume it will be large and therefore never explicitly |
||||||
|
* load it into memory, though if it is less than 4096 bytes it will be |
||||||
|
* in memory before it is written to its final location. When writing to |
||||||
|
* the final location, if the data is larger than the threshold, an attempt |
||||||
|
* is made to rename the temporary file to the given location. If it cannot |
||||||
|
* be renamed, it is streamed to the new location. |

<title>Overview of the com.fr.third.org.apache.commons.fileupload component</title> |
|

<p> |
|
||||||
A component for handling HTML file uploads as specified by |
|
||||||
<a href="http://www.ietf.org/rfc/rfc1867.txt" target="_top">RFC 1867</a>. |
|
||||||
This component provides support for uploads within both servlets (JSR 53) |
|
||||||
and portlets (JSR 168). |
|
||||||
</p> |
|
||||||
<p> |
|
||||||
While this package provides the generic functionality for file uploads, |
|
||||||
these classes are not typically used directly. Instead, normal usage |
|
||||||
involves one of the provided extensions of |
|
||||||
{@link com.fr.third.org.apache.commons.fileupload.FileUpload FileUpload} such as |
|
||||||
{@link com.fr.third.org.apache.commons.fileupload.servlet.ServletFileUpload ServletFileUpload} |
|
||||||
or |
|
||||||
{@link com.fr.third.org.apache.commons.fileupload.portlet.PortletFileUpload PortletFileUpload}, |
|
||||||
together with a factory for |
|
||||||
{@link com.fr.third.org.apache.commons.fileupload.FileItem FileItem} instances, |
|
||||||
such as |
|
||||||
{@link com.fr.third.org.apache.commons.fileupload.disk.DiskFileItemFactory DiskFileItemFactory}. |
|
||||||
</p> |
|
||||||
<p> |
|
||||||
The following is a brief example of typical usage in a servlet, storing |
|
||||||
the uploaded files on disk. |
|
||||||
</p> |
|
||||||
<pre> |
|
||||||
public void doPost(HttpServletRequest req, HttpServletResponse res) { |
|
||||||
DiskFileItemFactory factory = new DiskFileItemFactory(); |
|
||||||
// maximum size that will be stored in memory |
|
||||||
factory.setSizeThreshold(4096); |
|
||||||
// the location for saving data that is larger than getSizeThreshold() |
|
||||||
factory.setRepository(new File("/tmp")); |
|
||||||
|
|
||||||
ServletFileUpload upload = new ServletFileUpload(factory); |
|
||||||
// maximum size before a FileUploadException will be thrown |
|
||||||
upload.setSizeMax(1000000); |
|
||||||
|
|
||||||
List fileItems = upload.parseRequest(req); |
|
||||||
// assume we know there are two files. The first file is a small |
|
||||||
// text file, the second is unknown and is written to a file on |
|
||||||
// the server |
|
||||||
Iterator i = fileItems.iterator(); |
|
||||||
String comment = ((FileItem)i.next()).getString(); |
|
||||||
FileItem fi = (FileItem)i.next(); |
|
||||||
// filename on the client |
|
||||||
String fileName = fi.getName(); |
|
||||||
// save comment and filename to database |
|
||||||
... |
|
||||||
// write the file |
|
||||||
fi.write(new File("/www/uploads/", fileName)); |
|
||||||
} |
|
||||||
</pre> |
|
||||||
<p> |
|
||||||
In the example above, the first file is loaded into memory as a |
|
||||||
<code>String</code>. Before calling the <code>getString</code> method, |
|
||||||
the data may have been in memory or on disk depending on its size. The |
|
||||||
second file we assume it will be large and therefore never explicitly |
|
||||||
load it into memory, though if it is less than 4096 bytes it will be |
|
||||||
in memory before it is written to its final location. When writing to |
|
||||||
the final location, if the data is larger than the threshold, an attempt |
|
||||||
is made to rename the temporary file to the given location. If it cannot |
|
||||||
be renamed, it is streamed to the new location. |
|
||||||

<body> |
|

<p> |
|
||||||
An implementation of |
|
||||||
{@link com.fr.third.org.apache.commons.fileupload.FileUpload FileUpload} |
|
||||||
for use in servlets conforming to JSR 53. This implementation requires |
|
||||||
only access to the servlet's current <code>HttpServletRequest</code> |
|
||||||
instance, and a suitable |
|
||||||
{@link com.fr.third.org.apache.commons.fileupload.FileItemFactory FileItemFactory} |
|
||||||
implementation, such as |
|
||||||
{@link com.fr.third.org.apache.commons.fileupload.disk.DiskFileItemFactory DiskFileItemFactory}. |
|
||||||
</p> |
|
||||||
<p> |
|
||||||
The following code fragment demonstrates typical usage. |
|
||||||

||||||

|

DiskFileItemFactory factory = new DiskFileItemFactory(); |
