3. 编写数据到文件 我们将使用FileOutputStream、OutputStreamWriter和BufferedWriter来写入数据。这里将数据以UTF-8编码写入文件。 try{// 创建文件输出流FileOutputStreamfos=newFileOutputStream(file);// 将流包装为 OutputStreamWriter,并指定UTF-8编码OutputStreamWriterosw=newOutputStreamWriter(fos,"UTF-8");//...
importjava.io.BufferedWriter;importjava.io.FileOutputStream;importjava.io.OutputStreamWriter;publicclassCreateFileExample{publicstaticvoidmain(String[]args){StringfileName="中文文件.txt";Stringcontent="这是一个测试文件,内容为中文。";try(BufferedWriterwriter=newBufferedWriter(newOutputStreamWriter(newFileOutput...
java写文件UTF-8格式 String fileName = dir + File.separator + date + File.separator + (file.list().length + 1) + ".txt"; File file=newFile(fileName); BufferedWriter writer=null; FileOutputStream writerStream=newFileOutputStream(file); writer=newBufferedWriter(newOutputStreamWriter(writerStrea...
1 用notepad++打开文件，可以查看文件的编码。本文讲解的是以utf-8编码的文件的编码判断，若文件以utf-8无bom编码则无法判断。UTF-8编码的文件中，BOM占三个字节。这是个标识UTF-8编码文件的好办法，可以通过BOM来识别这个文件是否是UTF-8编码。2 判断文件编码的代码：InputStreaminputStream=newFileInputStream("E...
1. 通过Charset.forName(String charsetName)获取指定的Charset。例如UTF-8,GBK等。 ```java File file = new File("test.txt"); Charset charset = Charset.forName("UTF-8"); InputStream inputStream = new FileInputStream(file); Reader reader = new InputStreamReader(inputStream, charset); ...
* @param file * @param srcFilePath * @return java.lang.String */ private String saveAsUtf8(MultipartFile file, String srcFilePath) throws Exception{ InputStream inputStream = file.getInputStream(); String fileName = UUIDUtil.uuid32() + ".txt"; File tempFile = new File(srcFilePath);...
在创建FileReader对象时,我们可以指定文件的编码格式,如果我们要读取一个UTF-8编码的文件,我们可以这样做: import java.io.*; public class ReadFile { public static void main(String[] args) { try { File file = new File("example.txt");
public static boolean writeUTFFile(String fileName,String fileBody){ FileOutputStream fos = null; OutputStreamWriter osw = null; try { fos = new FileOutputStream(fileName); osw = new OutputStreamWriter(fos, "UTF-8"); osw.write(fileBody); ...
String xmla = StringFileToolkit.file2String(new File(“D:\\projects\\mailpost\\src\\a.xml”),“UTF-8”); byte[] b = xmla.getBytes(“UTF-8”); String xml = new String(b,3,b.length-3,“UTF-8”); ... 思路是:先按照UTF
new File("readWriteDemo.txt"); if(!file.exists()){ file.createNewFile(); } // 向文件中写入数据(这种方式会覆盖原始数据) OutputStream outputStream = new FileOutputStream(file); String str = "我们一起学习Java"; outputStream.write(str.getBytes(StandardCharsets.UTF_8)); outputStream.close(...
