所有已实现的接口:

InputStreamSource, Resource
```
public class VfsResource
extends AbstractResource
```
Copy from https://github.com/spring-projects/spring-framework.git, with less modifications JBoss VFS based Resource implementation.
As of Spring 4.0, this class supports VFS 3.x on JBoss AS 6+ (package org.jboss.vfs) and is in particular compatible with JBoss AS 7 and WildFly 8+.

从以下版本开始:

3.0

方法概要

所有方法实例方法具体方法
修饰符和类型	方法	说明
`long`	`contentLength()`	This method reads the entire InputStream to determine the content length.
`Resource`	`createRelative(java.lang.String relativePath)`	This implementation throws a FileNotFoundException, assuming that relative resources cannot be created for this resource.
`boolean`	`equals(java.lang.Object other)`	This implementation compares description strings.
`boolean`	`exists()`	This implementation checks whether a File can be opened, falling back to whether an InputStream can be opened.
`java.lang.String`	`getDescription()`	Return a description for this resource, to be used for error output when working with the resource.
`java.io.File`	`getFile()`	This implementation throws a FileNotFoundException, assuming that the resource cannot be resolved to an absolute file path.
`java.lang.String`	`getFilename()`	This implementation always returns `null`, assuming that this resource type does not have a filename.
`java.io.InputStream`	`getInputStream()`	Return an `InputStream` for the content of an underlying resource.
`java.net.URI`	`getUri()`	This implementation builds a URI based on the URL returned by `AbstractResource.getUrl()`.
`java.net.URL`	`getUrl()`	This implementation throws a FileNotFoundException, assuming that the resource cannot be resolved to a URL.
`int`	`hashCode()`	This implementation returns the description's hash code.
`boolean`	`isReadable()`	This implementation always returns `true` for a resource that `exists` (revised as of 5.1).
`long`	`lastModified()`	This implementation checks the timestamp of the underlying File, if available.

public VfsResource(java.lang.Object resource)
```
    Create a new VfsResource wrapping the given resource handle.
    
    参数:
    
    resource - a org.jboss.vfs.VirtualFile instance (untyped in order to avoid a static dependency on the VFS API)

  - getInputStream
```
public java.io.InputStream getInputStream()
                                   throws java.io.IOException
```
    从接口复制的说明: InputStreamSource
    
    Return an InputStream for the content of an underlying resource.
    It is expected that each call creates a fresh stream.
    This requirement is particularly important when you consider an API such as JavaMail, which needs to be able to read the stream multiple times when creating mail attachments. For such a use case, it is required that each getInputStream() call returns a fresh stream.
    
    返回:
    
    the input stream for the underlying resource (must not be null)
    
    抛出:
    
    java.io.FileNotFoundException - if the underlying resource does not exist
    
    java.io.IOException - if the content stream could not be opened

    从类复制的说明: AbstractResource
    
    This implementation checks whether a File can be opened, falling back to whether an InputStream can be opened. This will cover both directories and content resources.

  - contentLength
```
public long contentLength()
                   throws java.io.IOException
```
    从类复制的说明: AbstractResource
    
    This method reads the entire InputStream to determine the content length. For a custom sub-class of InputStreamResource, we strongly recommend overriding this method with a more optimal implementation, e.g. checking File length, or possibly simply returning -1 if the stream can only be read once.

    覆盖:
