Java dispatcher servlet中没有uri为的http请求

我正在使用SpringMVC开发一个web应用程序，我是spring的新手。我在名为“mvc dispatcher”的DispatcherServlet中发现了一个异常，说明

未找到URI为[/SpringMVCSecurityXML/userinfo]的HTTP请求的映射。

我引用了一些类似的问题，但无法找出哪里出了问题。有人能帮我解决吗。我在身份验证完成后得到错误

控制器级别缺少@RequestMapping

@Controller
@RequestMapping("/test")
public class MainController {

您的url将是：

/SpringMVCSecurityXML/test/userinfo]

尝试将

添加到mvc dispatcher servlet配置中

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd

    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-4.1.xsd">

<mvc:annotation-driven/>
<context:component-scan base-package="org.o7planning.tutorial.springmvcsecurity.controller" />

确保导入xmlns:mvc

希望这能对您有所帮助。

您能更具体一点吗？因为我猜我在主控制器中有所有的RequestMapping。你能解决你的问题吗？非常感谢，现在它可以工作了。但是如果试图从头开始运行项目，它也会再次抛出相同的错误。你说的从头开始项目是什么意思？我的意思是当我关闭eclipse并重新启动IDE并运行项目时，它会弹出相同的错误。
