出现这个错误是因为使用了 ObjectMapper来转换json字符串，

解决的办法是 1 避免使用这个类
             google 的 Gson gson =new Gson() 就是个替代方案，具体的效率问题不讨论
             2 使用 ObjectMapper mapper=new ObjectMapper();
mapper.configure(JsonParser.Feature.ALLOW_UNQUOTED_CONTROL_CHARS, true);

3 在传入值的时候，去除回车符换行符制表符等

public static boolean isBlankOrNull(String str){  if(null==str)return true;  return str.length()==0;  }  /*** //去除字符串中空格、换行、制表 * @param str* @param pattern* @param replace* @return*/public static String replaceSpecialtyStr(String str,String pattern,String replace){  if(isBlankOrNull(pattern))  pattern="\\s*|\t|\r|\n"; if(isBlankOrNull(replace))  replace="";  return Pattern.compile(pattern).matcher(str).replaceAll(replace);  }
