限定符和类型	方法和说明
`long`	`contentLength()` This implementation reads the entire InputStream to calculate the content length.
`Resource`	`createRelative(String relativePath)` This implementation throws a FileNotFoundException, assuming that relative resources cannot be created for this resource.
`boolean`	`equals(Object obj)` 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.
`String`	`getDescription()` Return a description for this resource, to be used for error output when working with the resource.
`File`	`getFile()` This implementation throws a FileNotFoundException, assuming that the resource cannot be resolved to an absolute file path.
`String`	`getFilename()` This implementation always returns `null`, assuming that this resource type does not have a filename.
`InputStream`	`getInputStream()` Return an `InputStream`.
`URI`	`getURI()` This implementation builds a URI based on the URL returned by `AbstractResource.getURL()`.
`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`.
`long`	`lastModified()` This implementation checks the timestamp of the underlying File, if available.

  - getInputStream
```
public InputStream getInputStream()
                           throws IOException
```
    从接口复制的说明: InputStreamSource
    
    Return an InputStream.
    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:
    
    IOException - if the stream could not be opened ·
  - exists
```
public boolean exists()
```
    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.
    
    指定者:
    
    exists 在接口中 Resource
    
    覆盖:
    
    exists 在类中 AbstractResource
  - isReadable
```
public boolean isReadable()
```
    从类复制的说明: AbstractResource
    
    This implementation always returns true.
    
    指定者:
    
    isReadable 在接口中 Resource
    
    覆盖:
    
    isReadable 在类中 AbstractResource

    InputStreamSource.getInputStream()
  - getURL
```
public URL getURL()
           throws IOException
```
    从类复制的说明: AbstractResource
    
    This implementation throws a FileNotFoundException, assuming that the resource cannot be resolved to a URL.
    
    指定者:
    
    getURL 在接口中 Resource
    
    覆盖:
    
    getURL 在类中 AbstractResource
    
    抛出:
    
    IOException - if the resource cannot be resolved as URL, i.e. if the resource is not available as descriptor
  - getURI
```
public URI getURI()
           throws IOException
```
    从类复制的说明: AbstractResource
    
    This implementation builds a URI based on the URL returned by AbstractResource.getURL().
    
    指定者:
    
    getURI 在接口中 Resource
    
    覆盖:
    
    getURI 在类中 AbstractResource
    
    抛出:
    
    IOException - if the resource cannot be resolved as URI, i.e. if the resource is not available as descriptor
  - getFile
```
public File getFile()
             throws IOException
```
    从类复制的说明: AbstractResource
    
    This implementation throws a FileNotFoundException, assuming that the resource cannot be resolved to an absolute file path.
    
    指定者:
    
    getFile 在接口中 Resource
    
    覆盖:
    
    getFile 在类中 AbstractResource
    
    抛出:
    
    IOException - if the resource cannot be resolved as absolute file path, i.e. if the resource is not available in a file system
  - contentLength
```
public long contentLength()
                   throws IOException
```
    从类复制的说明: AbstractResource
    
    This implementation reads the entire InputStream to calculate the content length. Subclasses will almost always be able to provide a more optimal version of this, e.g. checking a File length.
    
    指定者:
    
    contentLength 在接口中 Resource
    
    覆盖:
    
    contentLength 在类中 AbstractResource
    
    抛出:
    
    IOException - if the resource cannot be resolved (in the file system or as some other known physical resource type)

  - lastModified
```
public long lastModified()
                  throws IOException
```
    从类复制的说明: AbstractResource
    
    This implementation checks the timestamp of the underlying File, if available.
    
    指定者:
    
    lastModified 在接口中 Resource
    
    覆盖:
    
    lastModified 在类中 AbstractResource

public Resource createRelative(String relativePath)
                        throws IOException
```
    从类复制的说明: AbstractResource
    
    This implementation throws a FileNotFoundException, assuming that relative resources cannot be created for this resource.
    
    指定者:
    
    createRelative 在接口中 Resource
    
    覆盖:
    
    createRelative 在类中 AbstractResource
    
    参数:
    
    relativePath - the relative path (relative to this resource)
    
    返回:
    
    the resource handle for the relative resource
    
    抛出:
    
    IOException - if the relative resource cannot be determined
  - getFilename
```
public String getFilename()
```
    从类复制的说明: AbstractResource
    
    This implementation always returns null, assuming that this resource type does not have a filename.

    从接口复制的说明: Resource
    
    Return a description for this resource, to be used for error output when working with the resource.
    Implementations are also encouraged to return this value from their toString method.
