找不到URI为spring security的HTTP请求的映射

我正在尝试学习Spring安全性，第一个代码示例是在我运行URL“”时出现这样的错误，我使用jetty插件作为服务器

错误：org.springframework.web.servlet.PageNotFound noHandlerFound 警告：在名为“mvc dispatcher”的DispatcherServlet中找不到URI为[/spring security helloworld xml/]的HTTP请求的映射

这是web.xml：

<web-app id="WebApp_ID" version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

}

这是mvc dispacher servlet.xml

问题似乎出在您的

web.xml

<import resource="[path to web-dispatcher-servlet]" />

基本上是这样的

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/spring-security.xml
    </param-value>
</context-param>

这不是一个真正干净的解决方案，但它应该适用于您的情况。我建议你在进入安全领域之前先研究一下。SpringSecurity确实是一个过滤器，不过在配置它时，了解SpringIOC是非常有用的

作为个人建议，SpringWebApp上下文的结构通常如下

• 根上下文（定义DB连接、事务管理、DAO和所有其他通用bean）
• web上下文，定义映射和控制器
• 安全上下文，通常包含在根上下文中，以在需要时利用方法安全性，定义所有与安全相关的内容

什么是spring安全helloworld xml？是您的应用程序上下文还是应用程序上下文为/。您如何托管此应用程序？我认为这是一个应用程序上下文尝试的问题”
