我认为问题在于您的 web.xml 仅将 *.html 请求映射到您的servlet，并且您正在向它发送一个没有 .html 后缀的请求.

I think that the problem is that your web.xml only maps *.html requests to your servlet, and you are sending it a request without a .html suffix.

一种解决方案是更改 servlet 映射.例如

One solution is to change the servlet mapping. For example

<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>*.</url-pattern>
</servlet-mapping>

匹配任何后缀，或

<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

匹配任何路径.
