1、InputStream转化为String 1.1 JDK原生提供 方法一: byte[] bytes = new byte[0]; bytes = new byte[inputStream.available()]; inputStream.read(bytes); String str = new String(bytes); 方法二: String result = new BufferedReader(new InputStreamReader(inputStream)) .lines().collect(Collectors....

Java String转成流InputStream 并下载成文件 引言 在Java开发中,有时候我们需要将一个字符串转换为流(InputStream),然后将流保存为文件。这在很多场景下都很有用,比如从服务端获取到的文件内容以字符串形式返回,我们需要将其保存到本地文件中。 本文将教你如何实现Java String转成流InputStream,并下载成文件。我们...

方法一:使用ByteArrayInputStream ByteArrayInputStream是Java IO库提供的一个类,它可以将字节数组作为输入流使用。我们可以先将String转换为字节数组,然后将字节数组作为输入流传入ByteArrayInputStream。 publicstaticInputStreamconvertStringToInputStream(Stringstr){byte[]bytes=str.getBytes();returnnewByteArrayInputStre...
