类 ServletContextResource

构造器详细资料

• ServletContextResource

  public ServletContextResource​(ServletContext servletContext,
                                String path)

  Create a new ServletContextResource.

  The Servlet 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:

  servletContext - the ServletContext to load from

  path - the path of the resource

方法详细资料

• getServletContext

  public final ServletContext getServletContext()

  Return the ServletContext for this resource.

• getPath

  public final String getPath()

  Return the path for this resource.

• exists

  public boolean exists()

  This implementation checks ServletContext.getResource.

  指定者:

  exists 在接口中 Resource

  覆盖:

  exists 在类中 AbstractFileResolvingResource

  另请参阅:

  ServletContext.getResource(String)

• isReadable

  public boolean isReadable()

  This implementation delegates to ServletContext.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:

  ServletContext.getResourceAsStream(String)

• getInputStream

  public InputStream getInputStream()
                             throws IOException

  This implementation delegates to ServletContext.getResourceAsStream, but throws a FileNotFoundException if no resource 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:

  ServletContext.getResourceAsStream(String)

• getURL

  public URL getURL()
             throws IOException

  This implementation delegates to ServletContext.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:

  ServletContext.getResource(String)

• getFile

  public File getFile()
               throws IOException

  This implementation resolves "file:" URLs or alternatively delegates to ServletContext.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:

  ServletContext.getResource(String), ServletContext.getRealPath(String)

• createRelative

  public Resource createRelative​(String relativePath)

  This implementation creates a ServletContextResource, applying the given path relative to the path of the underlying file of this resource descriptor.

  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

  StringUtils.applyRelativePath(String, String)

• getFilename

  public String getFilename()

  This implementation returns the name of the file that this ServletContext resource refers to.

  指定者:

  getFilename 在接口中 Resource

  覆盖:

  getFilename 在类中 AbstractResource

  另请参阅:

  StringUtils.getFilename(String)

• getDescription

  public String getDescription()

  This implementation returns a description that includes the ServletContext resource location.

  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)

  This implementation compares the underlying ServletContext resource locations.

  覆盖:

  equals 在类中 AbstractResource

  Resource.getDescription()

• hashCode

  public int hashCode()

  This implementation returns the hash code of the underlying ServletContext resource location.

  覆盖:

  hashCode 在类中 AbstractResource
