方法详细资料

getInputStream

public InputStream getInputStream()
                           throws IOException

从接口复制的说明: Resource

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:

FileNotFoundException - if the underlying resource doesn't exist

IOException - if the content stream could not be opened

exists

public boolean exists()

从接口复制的说明: Resource

Determine whether this resource actually exists in physical form.

This method performs a definitive existence check, whereas the existence of a Resource handle only guarantees a valid descriptor handle.

指定者:

exists 在接口中 Resource<URL>

覆盖:

exists 在类中 AbstractResource<URL>

getAbsolutePath

public String getAbsolutePath()

getRealResource

public URL getRealResource()

contentLength

public long contentLength()

从接口复制的说明: Resource

Determine the content length for this resource.

getUrl

public URL getUrl()

equals

public boolean equals(Object obj)

覆盖:

equals 在类中 Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object
