Java InputStream to ByteBuffer

问题:

I am reading dds textures, but since once built the jar I can't access those textures through url and file and have to use InputStream instead.

So I would need to know how I can obtain a from an java.io.InputStream.

Ps: no matter through 3rd part libraries, I just need it working

回答1:

For me the best in this case is Apache commons-io to handle this and similar tasks.

The IOUtils type has a static method to read an InputStream and return a byte[].

InputStream is; byte[] bytes = IOUtils.toByteArray(is); 

Internally this creates a ByteArrayOutputStream and copies the bytes to the output, then calls toByteArray().

UPDATE: as long as you have the byte array, as @Peter pointed, you have to convert to ByteBuffer

ByteBuffer.wrap(bytes)
