方法详细资料

getName

java.lang.String getName()

返回multipart form中的参数名称.

返回:

参数名称(never null or empty)

getOriginalFilename

getContentType

java.lang.String getContentType()

返回文件的content type。

返回:

the content type, or null if not defined (or no file has been chosen in the multipart form)

getSize

long getSize()

返回文件的大小（字节）.

返回:

the size of the file, or 0 if empty

getInputStream

java.io.InputStream getInputStream()
                            throws java.io.IOException

Return an InputStream to read the contents of the file from. The user is responsible for closing the stream.

返回:

抛出:

java.io.IOException - in case of access errors (if the temporary store fails)

appendMessage

void appendMessage(java.lang.String message)

处理过程中，要在上传完毕后提示前端的信息，常用于查到病毒但杀毒成功的信息。

参数:

message - 提示信息。

setInputStream

void setInputStream(java.io.InputStream stream)
             throws java.io.IOException

改变上传的文件，用于使用清除病毒以后的流替换原上传的文件流。

参数:

stream - 新的文件流。

抛出:

java.io.IOException

getMessages

java.util.Collection getMessages()

saveAs

void saveAs(com.seeyon.ctp.common.file.model.CtpAbstractFile file)
     throws java.io.IOException,
            java.lang.IllegalStateException

Transfer the received file to the given destination file.

This may either move the file in the filesystem, copy the file in the filesystem, or save memory-held contents to the destination file. If the destination file already exists, it will be deleted first.

If the file has been moved in the filesystem, this operation cannot be invoked again. Therefore, call this method just once to be able to work with any storage mechanism.

参数:

dest - the destination file

抛出:

java.io.IOException - in case of reading or writing errors

java.lang.IllegalStateException - if the file has already been moved in the filesystem and is not available anymore for another transfer
