code: public static String convertArrayToStr(Object[] str){
          StringBuilder sql = new StringBuilder();
          for(Object s : str){
              sql.append(",'").append(s).append("'");
          }
          return org.apache.commons.lang3.ArrayUtils.toString(sql).substring(1,sql.length());
      }
docs: 将数组转为为字符串 以下列形式显示
  new String[]{"a","b","c"} 转换为: 'a','b','c'
  @param str
  @return
