In the process of interface testing, most data interaction uses json format, but the effect of json output from console is far less beautiful than that of browser plug-in. After searching for some information, I decided to write a formatting method to output json information to the console. After some attempts, it has been completed. Share as follows:

    /**
     * Output json
     *
     * @param jsonObject json Format response entity
     */
    public static JSONObject output(JSONObject jsonObject) {
        if (MapUtils.isEmpty(jsonObject)) {
            output("json The object is empty!");
            return jsonObject;
        }
        String start = SourceCode.getManyString(SPACE_1, 4);
        String jsonStr = jsonObject.toString();// First transform json object into string object
        jsonStr = jsonStr.replaceAll("\\\\/", OR);
        int level = 0;// User tag hierarchy
        StringBuffer jsonResultStr = new StringBuffer("＞  ");// Create a new stringbuffer object, and the user receives the converted string string string
        for (int i = 0; i < jsonStr.length(); i++) {// Loop through each character
            char piece = jsonStr.charAt(i);// Get the current character
            // If the last character is a broken line, the first line is excluded by adding a marker at the beginning of the line according to the level value.
            if (i != 0 && '\n' == jsonResultStr.charAt(jsonResultStr.length() - 1)) {
                for (int k = 0; k < level; k++) {
                    jsonResultStr.append(start);
                }
            }
            switch (piece) {
                case ',':
                    // If it is ",", it will break the line.
                    char last = jsonStr.charAt(i - 1);
                    if ("\"0123456789le]}".contains(last + EMPTY)) {
                        jsonResultStr.append(piece + LINE);
                    } else {
                        jsonResultStr.append(piece);
                    }
                    break;
                case '{':
                case '[':
                    // If the character is {or [, then line break, level plus 1
                    jsonResultStr.append(piece + LINE);
                    level++;
                    break;
                case '}':
                case ']':
                    // If it is} or], break the line, level minus 1
                    jsonResultStr.append(LINE);
                    level--;
                    for (int k = 0; k < level; k++) {
                        jsonResultStr.append(start);
                    }
                    jsonResultStr.append(piece);
                    break;
                default:
                    jsonResultStr.append(piece);
                    break;
            }
        }
        output(LINE + "↘ ↘ ↘ ↘ ↘ ↘ ↘ ↘ json ↙ ↙ ↙ ↙ ↙ ↙ ↙ ↙ ↙ ↙ ↙ ↙" + LINE + jsonResultStr.toString().replaceAll(LINE, LINE + "＞  ") + LINE + "↘ ↘ ↘ ↘ ↘ ↘ ↘ ↘ json ↙ ↙ ↙ ↙ ↙ ↙ ↙ ↙ ↙ ↙ ↙ ↙");
        return jsonObject;
    }
    

Update the output display effect:

Note: There is "in JSON data", "This situation and value non-string (number and null or science and technology method) may have some display anomalies, and value value itself is a string of JSON data will also be treated as json. Generally speaking, it is enough and the effect is satisfactory.
