解决办法，在ObjectMapper配置中增加：
mapper.configure(Feature.ALLOW_UNQUOTED_CONTROL_CHARS, true) ;
强大一點，還有其他的：
// 允许整数前导为0,eg:"01"形式
mapper.configure(Feature.ALLOW_NUMERIC_LEADING_ZEROS, true);
mapper.configure(Feature.ALLOW_COMMENTS, true);
mapper.configure(Feature.ALLOW_UNQUOTED_FIELD_NAMES, true);
mapper.configure(Feature.ALLOW_SINGLE_QUOTES, true);
mapper.configure(Feature.ALLOW_UNQUOTED_CONTROL_CHARS, true);
