Solution to garbled value transfer in java

When doing JavaWeb, you will always encounter the problem of garbled Chinese value transmission from time to time. After you change all "ISO-8859-1" to "UTF-8", you still find that the problem still exists It's of no use. So I found a method that works all the time (at least for now), which is to force conversion to "UTF-8" encoding. Look at the code:

@RequestMapping("/success.html") public String success(String userCode, Model model) { try { // 编码转换，防止中文乱码 userCode = new String(userCode.getBytes("ISO-8859-1"), "UTF-8"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } log.info("userCode:" + userCode); model.addAttribute("userCode", userCode); return "success"; }

Another way is to add an encoding filter to the configuration web.xml file, which can also achieve Chinese value transmission without garbled characters.

  encodingFilter org.springframework.web.filter.CharacterEncodingFilter  encoding UTF-8    encodingFilter /*
