如何将类路径资源加载到字节数组？ [英] How to load a classpath resource to an array of byte?

问题描述

我知道 ，如何获取给定类路径资源的输入流，从输入流中读取直到我到达结尾，但这看起来是一个非常普遍的问题，并且我想知道是否有一个我不知道的API或一个可以使事情变得简单的库

I know how to get the inputstream for a given classpath resource, read from the inputstream until i reach the end, but it looks like a very common problem, and i wonder if there an API that I don't know, or a library that would make things as simple as

byte[] data = ResourceUtils.getResourceAsBytes("/assets/myAsset.bin")

或

byte[] data = StreamUtils.readStreamToEnd(myInputStream)

$ b例如
$ b

！

for example!

推荐答案

看看Google番石榴 ByteStreams .toByteArray（INPUTSTREAM），这可能就是您想要的。

Have a look at Google guava ByteStreams.toByteArray(INPUTSTREAM), this is might be what you want.
