How do I convert a String to an InputStream in Java?
提问by Iain
Given a string:
给定一个字符串：
String exampleString = "example";
How do I convert it to an InputStream?
我如何将其转换为InputStream?
采纳答案by Iain
Like this:
像这样：
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.
请注意，这假设您想要一个 InputStream ，它是一个字节流，表示您的原始字符串编码为UTF-8。
For versions of Java less than 7, replace StandardCharsets.UTF_8with "UTF-8".
对于小于 7 的 Java 版本，替换StandardCharsets.UTF_8为"UTF-8".

You could use a StringReaderand convert the reader to an input stream using the solution in this other stackoverflow post.
您可以使用StringReader并使用其他 stackoverflow post 中的解决方案将读取器转换为输入流。

I find that using Apache Commons IOmakes my life much easier.
我发现使用Apache Commons IO让我的生活更轻松。
String source = "This is the source of my input stream";
InputStream in = org.apache.commons.io.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常见任务的快捷方式，您可以在项目中使用这些快捷方式。
