Question

我是Spring证券的新手。我创建了一个安装在WAS服务器上的hello world应用程序，并从浏览器中点击http://localhost:9080/SpringSecWebApp/welcome，但收到错误

我已经google了很多，并且在Stack Overflow上搜索了几乎所有关于相同问题的问题，但那里提到的解决方案并没有解决问题。请帮忙。

错误： PageNotFound W org.springframework.web.servlet.DispatcherServlet noHandlerFound在DispatcherServlet中找不到带有URI [/ SpringSecWebApp / welcome]的HTTP请求的映射，名称为＆＃39; mvc-dispatcher＆＃39;

Answer 1

应该参考编写控制器的包。换句话说，如果您的控制器位于com.springwebapp包中，请使用<context:component-scan base-package="com.springwebapp" />

修改根据您的评论我添加更多代码：试试这个：

<mvc:default-servlet-handler /> <context:component-scan base-package="com.springwebapp" use-default-filters="false"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan>

编辑2 ：再次根据您的评论我更改了代码。请试试这个：

<context:component-scan base-package="com.springwebapp" use-default-filters="false"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan>

**删除了default-servlet-handler

PageNotFound - noHandlerFound在DispatcherServlet中找不到带有URI [/ SpringSecWebApp / welcome]的HTTP请求的映射，名称为＆＃39; mvc-dispatcher＆＃39;
