Answer 1

错误信息告诉你，java 的登录首选页Login.aspx是有问题的。你看看路径或里头代码。

Answer 2

java.lang.IllegalArgumentException: Invalid <url-pattern> Login.aspx in servlet mapping
这个地方 表明 <url-pattern> 这个地方传了个不合法的参数,可能是类型不对,你在好好看看 

Answer 3

<url-pattern> Login.aspx  java的是jsp啊？？

Answer 4

<url-pattern>里边配置的不合法，有问题 

Answer 5

<url-pattern> Login.asp第一参数前面有空格。第二<url-pattern>是以/开头的
<url-pattern>/Login.asp</url-pattern>
