I want it to be:

Url-mapping
网址映射
<servlet-mapping>
<servlet-name>springapp</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
I have tried changing the url-pattern with no luck (* and /*).
我试过在没有运气的情况下更改 url 模式（* 和 /*）。

<servlet>
<servlet-name>spring-mvc</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring-mvc</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
Then you need to register your urls to be handled by a particular controller. See the following
然后您需要注册由特定控制器处理的 url。请参阅以下内容

<url-pattern>/</url-pattern>

As far as I know you can't do this if you're using JSP's as your view for controllers.
据我所知，如果您使用 JSP 作为控制器的视图，则无法执行此操作。
Because when you pass a model to a JSP, Spring MVC internally performs a 'forward' to the URL of the JSP. If you use <url-pattern>/*</url-pattern>then this forward will also be handled by your DispatcherServlet and not by your JSP view.
因为当您将模型传递给 JSP 时，Spring MVC 在内部执行到 JSP 的 URL 的“转发”。如果您使用，<url-pattern>/*</url-pattern>那么这个转发也将由您的 DispatcherServlet 处理，而不是由您的 JSP 视图处理。
What you can do is use <url-pattern>/something</url-pattern>and have your JSP's in a different directory
您可以做的是使用<url-pattern>/something</url-pattern>并将您的 JSP 放在不同的目录中

In Spring 3.2 at least, the accepted answer above is very nearly but not quite what's needed. The web.xml bit below just worked for me, and I'm adding it to the thread here for reference of whoever googles this next...
至少在 Spring 3.2 中，上面接受的答案非常接近但不完全是需要的。下面的 web.xml 位只对我有用，我将它添加到这里的线程中以供下一个谷歌搜索的人参考......
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

Try first:
先试试：
<servlet-mapping>
<servlet-name>spring-mvc</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>
If that doesn't work then problem is somewhere else. Is your Apache set up to forward those urls to Tomcat? Something like:
如果那不起作用，那么问题出在其他地方。您的 Apache 是否设置为将这些 url 转发到 Tomcat？就像是：
JkMount /hello worker1

Have you tried <url-pattern>/*</url-pattern>in the servlet mapping and <bean name="/hello" .../>?
您是否尝试 <url-pattern>/*</url-pattern>过 servlet 映射和<bean name="/hello" .../>？
