修饰符和类型	方法	说明
void	close()
JarEntryResource	createRelative(String relativePath)	This implementation creates a UrlBasedResource, delegating to UrlResource.createRelativeURL(String) for adapting the relative path.
boolean	equals(Object other)	This implementation compares the underlying URL references.
boolean	exists()	This implementation checks whether a File can be opened, falling back to whether an InputStream can be opened.
String	getEntryName()
File	getFile()	This implementation returns a File reference for the underlying URL/URI, provided that it refers to a file in the file system.
InputStream	getInputStream()	This implementation opens an InputStream for the given URL.
protected static String	getJarFilePath(String path)
protected static String	getJarUrl(String path)
JarOutputStream	getOutputStream()	Return an OutputStream for the underlying resource, allowing to (over-)write its content.
int	hashCode()	This implementation returns the hash code of the underlying URL reference.
boolean	isDirectory()	Tests whether the resource denoted by this abstract pathname is a directory.
String[]	list()	list Resource under the directory
String	toString()	Return a description for this resource, to be used for error output when working with the resource.

构造器详细资料

JarEntryResource

public JarEntryResource(URL url)

JarEntryResource

public JarEntryResource(String path)
                 throws IOException

抛出:

IOException

JarEntryResource

public JarEntryResource(URL url,
 File jarFile,
 String entryName)

方法详细资料

getJarUrl

protected static String getJarUrl(String path)

getJarFilePath

protected static String getJarFilePath(String path)

getEntryName

public String getEntryName()

getInputStream

public InputStream getInputStream()
                           throws IOException

从类复制的说明: UrlResource

This implementation opens an InputStream for the given URL.

It sets the useCaches flag to false, mainly to avoid jar file locking on Windows.

指定者:

getInputStream 在接口中 InputStreamSource

覆盖:

getInputStream 在类中 UrlResource

返回:

input stream of Resource content

抛出:

IOException - If an input exception occurs

另请参阅:

• URL.openConnection()
• URLConnection.setUseCaches(boolean)
• URLConnection.getInputStream()

getOutputStream

public JarOutputStream getOutputStream()
                                throws IOException

从接口复制的说明: OutputStreamSource

Return an OutputStream for the underlying resource, allowing to (over-)write its content.

指定者:

getOutputStream 在接口中 JarResource

指定者:

getOutputStream 在接口中 OutputStreamSource

抛出:

IOException - if the stream could not be opened

getFile

public File getFile()

从类复制的说明: UrlResource

This implementation returns a File reference for the underlying URL/URI, provided that it refers to a file in the file system.

指定者:

getFile 在接口中 Resource

覆盖:

getFile 在类中 UrlResource

另请参阅:

• ResourceUtils.getFile(java.net.URL, String)

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 AbstractFileResolvingResource

isDirectory

public boolean isDirectory()
                    throws IOException

从接口复制的说明: Resource

Tests whether the resource denoted by this abstract pathname is a directory.

Where it is required to distinguish an I/O exception from the case that the file is not a directory, or where several attributes of the same file are required at the same time, then the Files.readAttributes method may be used.

指定者:

isDirectory 在接口中 Resource

覆盖:

isDirectory 在类中 AbstractResource

返回:

true if and only if the file denoted by this abstract pathname exists and is a directory; false otherwise

抛出:

IOException - cannot determine resource

list

public String[] list()
              throws IOException

从接口复制的说明: Resource

list Resource under the directory

指定者:

list 在接口中 Resource

覆盖:

list 在类中 AbstractResource

返回:

Resource names

抛出:

IOException - if the resource is not available

createRelative

public JarEntryResource createRelative(String relativePath)
                                throws IOException

从类复制的说明: UrlResource

This implementation creates a UrlBasedResource, delegating to UrlResource.createRelativeURL(String) for adapting the relative path.

指定者:

createRelative 在接口中 Resource

覆盖:

createRelative 在类中 UrlResource

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

另请参阅:

• UrlResource.createRelativeURL(String)

toString

public String toString()

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:

toString 在接口中 Resource

覆盖:

toString 在类中 UrlResource

另请参阅:

• Object.toString()

equals

public boolean equals(Object other)

从类复制的说明: UrlResource

This implementation compares the underlying URL references.

覆盖:

equals 在类中 UrlResource

hashCode

public int hashCode()

从类复制的说明: UrlResource

This implementation returns the hash code of the underlying URL reference.

覆盖:

hashCode 在类中 UrlResource

close

public void close()
           throws Exception

指定者:

close 在接口中 AutoCloseable

抛出:

Exception
