所有已实现的接口:
ContextResource, InputStreamSource, Resource
```
public class PortletContextResource
extends AbstractFileResolvingResource
implements ContextResource
```
Resource implementation for PortletContext resources, interpreting relative paths within the portlet application root directory.
Always supports stream access and URL access, but only allows java.io.File access when the portlet application archive is expanded.

所有方法实例方法具体方法
修饰符和类型	方法	说明
`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 `PortletContext.getResource`.
`String`	`getDescription()`	Return a description for this resource, to be used for error output when working with the resource.
`File`	`getFile()`	This implementation resolves "file:" URLs or alternatively delegates to `PortletContext.getRealPath`, throwing a FileNotFoundException if not found or not resolvable.
`String`	`getFilename()`	This implementation always returns `null`, assuming that this resource type does not have a filename.
`InputStream`	`getInputStream()`	This implementation delegates to `PortletContext.getResourceAsStream`, but throws a FileNotFoundException if not found.
`String`	`getPath()`	Return the path for this resource.
`String`	`getPathWithinContext()`	Return the path within the enclosing 'context'.
`PortletContext`	`getPortletContext()`	Return the PortletContext for this resource.
`URL`	`getURL()`	This implementation delegates to `PortletContext.getResource`, but throws a FileNotFoundException if no resource found.
`int`	`hashCode()`	This implementation returns the description's hash code.
`boolean`	`isReadable()`	This implementation delegates to `PortletContext.getResourceAsStream`, which returns `null` in case of a non-readable resource (e.g. a directory).

  - PortletContextResource
```
public PortletContextResource(PortletContext portletContext,
                              String path)
```
    Create a new PortletContextResource.
    The Portlet spec requires that resource paths start with a slash, even if many containers accept paths without leading slash too. Consequently, the given path will be prepended with a slash if it doesn't already start with one.
    参数:
    portletContext - the PortletContext to load from
    path - the path of the resource
- 方法详细资料
  - getPortletContext
```
public final PortletContext getPortletContext()
```
    Return the PortletContext for this resource.
  - getPath
```
public final String getPath()
```
    Return the path for this resource.
  - exists
```
public boolean exists()
```
    This implementation checks PortletContext.getResource.
    指定者:
    exists 在接口中 Resource
    覆盖:
    exists 在类中 AbstractFileResolvingResource
    另请参阅:
    PortletContext.getResource(String)
  - isReadable
```
public boolean isReadable()
```
    This implementation delegates to PortletContext.getResourceAsStream, which returns null in case of a non-readable resource (e.g. a directory).
    指定者:
    isReadable 在接口中 Resource
    覆盖:
    isReadable 在类中 AbstractFileResolvingResource
    另请参阅:
    PortletContext.getResourceAsStream(String)
  - getInputStream
```
public InputStream getInputStream()
                           throws IOException
```
    This implementation delegates to PortletContext.getResourceAsStream, but throws a FileNotFoundException if not found.
    指定者:
    getInputStream 在接口中 InputStreamSource
    返回:
    the input stream for the underlying resource (must not be null)
    抛出:
    FileNotFoundException - if the underlying resource doesn't exist
    IOException - if the content stream could not be opened
    另请参阅:
    PortletContext.getResourceAsStream(String)
  - getURL
```
public URL getURL()
           throws IOException
```
    This implementation delegates to PortletContext.getResource, but throws a FileNotFoundException if no resource found.
    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
    另请参阅:
    PortletContext.getResource(String)
  - getFile
```
public File getFile()
             throws IOException
```
    This implementation resolves "file:" URLs or alternatively delegates to PortletContext.getRealPath, throwing a FileNotFoundException if not found or not resolvable.
    指定者:
    getFile 在接口中 Resource
    覆盖:
    getFile 在类中 AbstractFileResolvingResource
    抛出:
    FileNotFoundException - if the resource cannot be resolved as absolute file path, i.e. if the resource is not available in a file system
    IOException - in case of general resolution/reading failures
    另请参阅:
    PortletContext.getResource(String), PortletContext.getRealPath(String)
  - createRelative
```
public Resource createRelative(String relativePath)
```
    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
  - 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.
    指定者:
    getFilename 在接口中 Resource
    覆盖:
    getFilename 在类中 AbstractResource
  - getDescription
```
public String getDescription()
```
    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.
    指定者:
    getDescription 在接口中 Resource
    另请参阅:
    Object.toString()
  - getPathWithinContext
```
public String getPathWithinContext()
```
    从接口复制的说明: ContextResource
    Return the path within the enclosing 'context'.
    This is typically path relative to a context-specific root directory, e.g. a ServletContext root or a PortletContext root.
    指定者:
    getPathWithinContext 在接口中 ContextResource
  - equals
```
public boolean equals(Object obj)
```
    从类复制的说明: AbstractResource
    This implementation compares description strings.
    覆盖:
    equals 在类中 AbstractResource
    另请参阅:
    Resource.getDescription()
  - hashCode
```
public int hashCode()
```
    从类复制的说明: AbstractResource
    This implementation returns the description's hash code.
    覆盖:
    hashCode 在类中 AbstractResource
