+	 * <p>
+	 * <b>参数解释：</b>
+	 * <ul>
+	 * <li>词语：预设的词语范围，用于设定随机返回词语的范围</li>
+	 * </ul>
+	 * <p>
+	 * <p>
+	 * <b>示例：</b>
+	 * <ul>
+	 * <li>${word(in,out,stop)}——表示从词语in、out或者stop中随机返回一个词语</li>
+	 * </ul>
+	 * </p>
+	 * <p>
+	 * <b>注意：</b>
+	 * <ol>
+	 * <li>括号中至少要存在一个词语，否则不会匹配</li>
+	 * <li>词语间分隔符为英文的逗号，在词语中请勿使用该符号</li>
+	 * </ol>
+	 * </p>
+	 * 
+	 * @param splitText 分隔符，必须按照正则表达式的形式传入
