Like this:

是这样的:

InputStream stream = new ByteArrayInputStream(exampleString.getBytes(StandardCharsets.UTF_8));

Note that this assumes that you want an InputStream that is a stream of bytes that represent your original string encoded as UTF-8.

注意，这假定您需要一个InputStream，它是一个字节流，表示以UTF-8编码的原始字符串。

For versions of Java less than 7, replace StandardCharsets.UTF_8 with "UTF-8".

对于Java小于7的版本，替换标准字符集。UTF_8“utf - 8”。

I find that using Apache Commons IO makes my life much easier.

我发现使用Apache Commons IO使我的生活更轻松。

String source = "This is the source of my input stream";
InputStream in = IOUtils.toInputStream(source, "UTF-8");

You may find that the library also offer many other shortcuts to commonly done tasks that you may be able to use in your project.

您可能会发现，该库还提供了许多其他快捷方式，用于您可以在项目中使用的常见任务。
