Java reads json data and solves Chinese garbled characters

Java code that reads json data and appears garbled: (Recommended: java video tutorial)

//从json文件中读取数据
		StringBuffer stringBuffer = new StringBuffer();
		try {
			BufferedReader bufferedReader = 
					new BufferedReader(new InputStreamReader(new FileInputStream(file)));
			String line;
			while((line=bufferedReader.readLine()) != null) {
				stringBuffer.append(line);
			}
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		//开始解析
		JSONObject jsonObject = new JSONObject(stringBuffer.toString());

Solution

according to According to the online description, the file is set to UTF-8 encoding, but if it is saved as a UTF-8 encoded file, there will be 3 more bytes of data identifying the encoding type in the file header, causing the JSONObject object to fail to be parsed. The reason: it is not { beginning.

Idea: We open it by editing, and the UTF-8 encoding format is displayed normally. Then we use the binary editing tool to delete the UTF-8 identifier EF BB BF in the file header, and then in the code, use InputStreamReader to let the data flow from UTF-8 encoding is used in the process of converting byte stream to character stream

BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(new FileInputStream(file), "UTF-8"));
