个人笔记02-分割商品id,分割字符串

def goodsIdsSplit(String goods_id){
    if(!goods_ids)
    return ""
    String[] goods_arr = goods_ids.split(",")
    StringBuffer sb = new StringBuffer() 
    //商品id钱加单引号
    goods_arr.each{
         sb.append("'").append(it).append("'").append(",")
    }
    //去掉最后一个逗号
    String goods_params = sb.deleteCharAt(sb.length()-1)
    return goods_params

}

.each{}的结果就是

假如goods_arr的数据	.each{}出来的数据
aa bb cc dd	‘aa’,'bb','cc','dd'
