英文:
Read uploadedFile's content with it's original format string(text)
问题
我上传了一个文件，可以获取文件名、类型、大小和内容。内容以字节数组的形式呈现。我希望将内容以其原始格式，即文本文件（字符串），获取出来。是否有办法像io中的File那样读取primefaces的uploadedFile，或者有没有办法将内容以字符串格式读取出来。
英文:
I uploaded a file and i can get the file name, type, size and content. The content is in a format of byte array. I want the cotnet in it's original format, which is text file(String). Is there a way to read the uploadedFile of the primefaces like the File in io. or is there a way i can read the content in a string format.

很简单。上传的文件将包含一个byte[]，其中包含上传文件的内容，因此您可以从中简单地构造一个String：
public void handleUpload(final FileUploadEvent event) throws IOException {
String content = new String(event.getFile().getContent(), StandardCharsets.UTF_8);
}
另请参阅：
英文:
It's simple. The uploaded file will contain a byte[] of the contents of the uploaded file, so you can simply construct a String from it:
public void handleUpload(final FileUploadEvent event) throws IOException {
String content = new String(event.getFile().getContent(), StandardCharsets.UTF_8);
}
