Constructor Detail

ServletContextResource

public ServletContextResource(javax.servlet.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.

Parameters:

servletContext - the ServletContext to load from

path - the path of the resource

Method Detail

getServletContext

public final javax.servlet.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.

Specified by:

exists in interface org.springframework.core.io.Resource

Overrides:

exists in class org.springframework.core.io.AbstractFileResolvingResource

getInputStream

public InputStream getInputStream()
                           throws IOException

Throws:

IOException

See Also:

ServletContext.getResourceAsStream(String)

getURL

public URL getURL()
           throws IOException

Specified by:

getURL in interface org.springframework.core.io.Resource

Overrides:

getURL in class org.springframework.core.io.AbstractResource

Throws:

IOException

See Also:

ServletContext.getResource(String)

getFile

public File getFile()
             throws IOException

This implementation delegates to ServletContext.getRealPath, but throws a FileNotFoundException if not found or not resolvable.

Specified by:

Overrides:

getFile in class org.springframework.core.io.AbstractFileResolvingResource

Throws:

IOException

getFilename

public String getFilename()

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

Specified by:

getFilename in interface org.springframework.core.io.Resource

Overrides:

getFilename in class org.springframework.core.io.AbstractResource

getDescription

public String getDescription()

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

Specified by:

getDescription in interface org.springframework.core.io.Resource

getPathWithinContext
