错误 org.springframework.web.servlet.PageNotFound noHandlerFound 警告：在名为“HelloWeb”的DispatcherServlet中找不到URI为[/SpringMVC/]的HTTP请求的映射。请尝试在
HelloWeb servlet.xml
中添加
，然后在TutorialController.java类中添加
@Controller

尝试将web.xml中的代码更改为：

<servlet-mapping> <servlet-name>HelloWeb</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>

当我运行服务器时，它抛出一个404。你没有
/
的url映射，你在使用磁贴吗？点击此url:
http://localhost:8080/HelloWeb/hello
已尝试但不起作用：（编辑了我的答案，可能现在就可以了。刚刚试过了，伙计..仍然点击404。你应该试着点击url:/SpringMVC/hello。因为/SpringMVC没有直接映射，
SpringMVC
不是应用程序名。
HelloWeb
是应用程序名..所以你必须点击
http://localhost:8080/HelloWeb/hello进行了请求的更改，但仍然是相同的错误…我已用更改更新了我的问题。
