Method Detail

convertSizeToBytes

public long convertSizeToBytes(java.lang.String sizeString,
                               long defaultSize)

Converts a size value from a string representation to its numeric value. The string must be of the form nnnm, where nnn is an arbitrary decimal value, and m is a multiplier. The multiplier must be one of 'K', 'M' and 'G', representing kilobytes, megabytes and gigabytes respectively. If the size value cannot be converted, for example due to invalid syntax, the supplied default is returned instead.

Parameters:

sizeString - The string representation of the size to be converted.

defaultSize - The value to be returned if the string is invalid.

Returns:

The actual size in bytes.

getRepositoryPath

public java.lang.String getRepositoryPath(javax.servlet.ServletContext servletContext)

Returns the path to the temporary directory to be used for uploaded files which are written to disk. The directory used is determined from the first of the following to be non-empty.

1. A temp dir explicitly defined using the saveDir attribute of the <multipartConfig> element in the Spring config file.
2. The temp dir specified by the javax.servlet.context.tempdir attribute.

Specified by:

getRepositoryPath in interface IMultipartConfig

Parameters:

servletContext - servlet context

Returns:

The path to the directory to be used to store uploaded files.

addFileParameter

public void addFileParameter(RequestWrapper request,
                             org.apache.commons.fileupload.FileItem item)

Specified by:

addFileParameter in interface IMultipartConfig

Parameters:

request - The request in which the parameter was specified.

item - The file item for the parameter to add.

setMaxFileSize

public void setMaxFileSize(java.lang.String maxFileSize)

Parameters:

maxFileSize - The maximum size to set.

setTempDir

public void setTempDir(java.lang.String tempDir)

Parameters:

tempDir - The tempDir to set.

getSizeMax

protected long getSizeMax()

Returns the maximum allowable size, in bytes, of an uploaded file. The value is obtained from the Spring configuration.

Returns:

The maximum allowable file size, in bytes.
