方法详细资料

close

public static void close(URLConnection conn)

Closes a URLConnection.

参数:

conn - the connection to close.

从以下版本开始:

2.4

closeQuietly

public static void closeQuietly(Reader input)

Unconditionally close an Reader.

Equivalent to Reader.close(), except any exceptions will be ignored. This is typically used in finally blocks.

Example code:

   char[] data = new char[1024];
   Reader in = null;
   try {
       in = new FileReader("foo.txt");
       in.read(data);
       in.close(); //close errors are handled
   } catch (Exception e) {
       // error handling
   } finally {
       IOUtils.closeQuietly(in);
   }
 

参数:

input - the Reader to close, may be null or already closed

closeQuietly

public static void closeQuietly(Writer output)

Unconditionally close a Writer.

Equivalent to Writer.close(), except any exceptions will be ignored. This is typically used in finally blocks.

Example code:

   Writer out = null;
   try {
       out = new StringWriter();
       out.write("Hello World");
       out.close(); //close errors are handled
   } catch (Exception e) {
       // error handling
   } finally {
       IOUtils.closeQuietly(out);
   }
 

参数:

output - the Writer to close, may be null or already closed

closeQuietly

public static void closeQuietly(InputStream input)

Unconditionally close an InputStream.

Equivalent to InputStream.close(), except any exceptions will be ignored. This is typically used in finally blocks.

Example code:

   byte[] data = new byte[1024];
   InputStream in = null;
   try {
       in = new FileInputStream("foo.txt");
       in.read(data);
       in.close(); //close errors are handled
   } catch (Exception e) {
       // error handling
   } finally {
       IOUtils.closeQuietly(in);
   }
 

参数:

input - the InputStream to close, may be null or already closed

closeQuietly

public static void closeQuietly(OutputStream output)

Unconditionally close an OutputStream.

Equivalent to OutputStream.close(), except any exceptions will be ignored. This is typically used in finally blocks.

Example code:

 byte[] data = "Hello, World".getBytes();

 OutputStream out = null;
 try {
     out = new FileOutputStream("foo.txt");
     out.write(data);
     out.close(); //close errors are handled
 } catch (IOException e) {
     // error handling
 } finally {
     IOUtils.closeQuietly(out);
 }
 

参数:

output - the OutputStream to close, may be null or already closed

closeQuietly

public static void closeQuietly(Closeable closeable)

Unconditionally close a Closeable.

Equivalent to Closeable.close(), except any exceptions will be ignored. This is typically used in finally blocks.

Example code:

   Closeable closeable = null;
   try {
       closeable = new FileReader("foo.txt");
       // process closeable
       closeable.close();
   } catch (Exception e) {
       // error handling
   } finally {
       IOUtils.closeQuietly(closeable);
   }
 

参数:

closeable - the object to close, may be null or already closed

从以下版本开始:

closeQuietly

public static void closeQuietly(Socket sock)

Unconditionally close a Socket.

Equivalent to Socket.close(), except any exceptions will be ignored. This is typically used in finally blocks.

Example code:

   Socket socket = null;
   try {
       socket = new Socket("http://www.foo.com/", 80);
       // process socket
       socket.close();
   } catch (Exception e) {
       // error handling
   } finally {
       IOUtils.closeQuietly(socket);
   }
 

参数:

sock - the Socket to close, may be null or already closed

从以下版本开始:

   Selector selector = null;
   try {
       selector = Selector.open();
       // process socket
