java - Spring security不解析xml

Question

我有一个问题，无法使用 spring mvc 3.2.4 和 spring security 3.1.4。他们抛出无法解析 spring-security.xml 的异常。这是我的示例代码:

Controller :

    @Controller
public class HomeController {

    @RequestMapping("/home")
    public ModelAndView getHome() {
        String string = "Congrats ! You are done with your first Spring Security configuration !";
        return new ModelAndView("home", "string", string);
    }

}

web.xml

<servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/mvc-dispatcher-servlet.xml,
        /WEB-INF/spring-security.xml
    </param-value>
</context-param>

<!-- Spring Security -->
<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

spring-security.xml:

Answer 1

您的错误非常明显:

FileNotFoundException: Could not open ServletContext resource [/WEB-INF/spring-security.xml]

既然您说该文件位于上述位置，那么它可能是以下位置之一:

• 文件在获取字节范围锁的应用程序中打开，从而阻止 Spring 进程访问它。尝试关闭所有编辑器应用程序。

• 您正在查看 spring-security.xml 的不同副本。在根目录中搜索该文件的所有副本。您可能正在查看完全不同的目录，因此您可能会看到该文件，但实际上并未引用它。

• 文件已损坏。尝试将内容复制并粘贴到新文件中并保存。
