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");// 创建 BufferedWriter ...
";try(BufferedWriterwriter=newBufferedWriter(newOutputStreamWriter(newFileOutputStream(fileName),"UTF-8"))){writer.write(content);System.out.println("文件创建成功: "+fileName);}catch(Exceptione){e.printStackTrace();}}} 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16....
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...
Java FileWriter 默认是用(ISO-8859-1 or US-ASCII)西方编码的,总之不是UTF-8的,而FileWriter类有getEncoding方法,却没有setEncoding的方法,如下的写法可以使正确输出UTF-8的文件: OutputStreamWriter out = new OutputStreamWriter(new FileOutputStream(path),"UTF-8"); 或者 Writer out = new BufferedWriter( ...
private String saveAsUtf8(MultipartFile file, String srcFilePath) throws Exception{ InputStream inputStream = file.getInputStream(); String fileName = UUIDUtil.uuid32() + ".txt"; File tempFile = new File(srcFilePath); if (!tempFile.exists()) { tempFile.mkdirs(); } String srcFileName...
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); ...
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(...
FF FE = UTF-16, little-endian 下面举个例子,针对UTF-8的文件BOM做个处理: String xmla = StringFileToolkit.file2String(new File(“D:\\projects\\mailpost\\src\\a.xml”),“UTF-8”); byte[] b = xmla.getBytes(“UTF-8”);
* @param fileBody 文件内容 * @return */ 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"); ...
FileUtils.readFileToString ()是在单个语句中将整个文件读入字符串的绝佳方法。 在单个语句中读取文件 File file =newFile("c:/temp/demo.txt");Stringcontent = FileUtils.readFileToString(file,"UTF-8"); 以上就是关于“Java读取文件内容到字符串”的介绍,大家如果想了解更多相关知识,不妨来关注一下动力节点...
