【学习笔记】【JAVA】Map.toString()后的字符串转换回Map类型

  public static void main(String[] args) {
    String str = "{src_text=小牛上传,tgt_text=Ewota eswi,from=zh,to=izz,username=1109}";
    Map<String, String> map = mapStringToMap(str);
    System.out.println(map);
    System.out.println(map.get("file_url"));
    System.out.println(map.get("src_text"));
    System.out.println(map.get("tgt_text"));
    System.out.println(map.get("from"));
    System.out.println(map.get("to"));
    System.out.println(map.get("username"));
  }
  public static Map<String, String> mapStringToMap(String str) {
    str = str.substring(1, str.length() - 1);
    String[] strs = str.split(",");
    Map<String, String> map = new HashMap<String, String>();
    for (String string : strs) {
      String key = string.split("=")[0];
      String value = string.split("=")[1];
      map.put(key, value);
    }
    return map;
  }
