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
