 * 格式化字符串,此方法是抽取slf4j的核心方法.

 * <p>
 * 在java中,常会拼接字符串生成新的字符串值,在字符串拼接过程中容易写错或者位置写错<br>

 * slf4j的log支持格式化输出log,比如:<br>

 * 
 * <ul>
 * <li>LOGGER.debug("{}","feilong");</li>
 * <li>LOGGER.info("{},{}","feilong","hello");</li>

 *  "callbackUrl:[{}] ,length:[{}] can't {@code >}{}",
 *  callbackUrl,

 * 
 * <pre class="code">
 * return Slf4jUtil.format("{} [{}]", encode, encode.length());

 * 
 * @param messagePattern
 *            message的格式,比如 callbackUrl:[{}] ,length:[{}]
