没有人知道吗？？？愁人

java.lang.IllegalArgumentException: Illegal pattern character 'l'
是字母l 不是一啊

[shine333]

SimpleDateFormat的格式错误
里面出现了不认识的l（L not one)，如果想在某个位置固定输出的话，可以加单引号
比如

new SimpleDateFormat("yyyy'llllllllllll'-MM-dd")

将在年的后面出现若干个固定的l

好的 谢谢
我再仔细找找
另一个异常是什么意识啊？

是字符串解析出了问题 那本来就是L 不是一 没事跑这吓捣什么乱 害一顿找
