Spring Servlet 和 Spring 安全过滤器链 Url 模式

Question

我在调试 spring 安全 j_spring_security_check 和 j_spring_security_logout 上的那些 404 消息时遇到了很多麻烦。我相信 SpringServlet Url-Pattern、springSecurityFilterChain Url-Pattern and/Or sitemesh.

之间可能存在一些冲突

这是我的 web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    version="3.1">

    <filter-mapping>

    </filter-mapping>

    <context-param>
        <param-name>contextConfigLocation</param-name>

    </context-param>

    <servlet>

        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <init-param>

    </servlet>

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

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

    <filter>
        <filter-name>sitemesh</filter-name>
        <filter-class>org.sitemesh.config.ConfigurableSiteMeshFilter</filter-class>
    </filter>

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

</web-app>

还有我的 ApplicationContext（包括 spring-security 部分）：

<?xml version="1.0" encoding="UTF-8"?>

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

        <property name="order" value="1" />
    </bean>

    <security:http auto-config="true" use-expressions="true">

        <security:logout logout-url="/logout"/> 
    </security:http>

    <!-- Declare an authentication-manager to use a custom userDetailsService -->
    <security:authentication-manager>
        <security:authentication-provider user-service-ref="userDetailsService">

        </security:authentication-provider>
    </security:authentication-manager>

    <bean class="org.springframework.security.authentication.encoding.Md5PasswordEncoder" id="passwordEncoder" />

    <security:user-service id="userDetailsService">
        <security:user name="john" password="21232f297a57a5a743894a0e4a801fc3" authorities="ROLE_USER, ROLE_ADMIN" />
        <security:user name="jane" password="ee11cbb19052e40b07aac0ca060c23ee" authorities="ROLE_USER" />
    </security:user-service>


    <bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">

        <property name="defaultEncoding" value="UTF-8">

    </bean>

    <bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
        <property name="paramName" value="lang">
        </property>
    </bean>

    <bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
        <property name="defaultLocale" value="pt">
        </property>
    </bean>
</beans>

还有一个基本的主页控制器，returns 带有 sitemesh 的视图：

@Controller
@RequestMapping(value = "/")
public class HomeController {

    @RequestMapping(method=RequestMethod.GET)
    public String index()
    {
        return "home/index";
    }
}

这适用于登录。如果我访问 localhost/portal，我将被重定向到 spring 的默认登录页面，然后我将被重定向到“/”。问题是这里 URL：

<a href="<c:url value="/logout" />">Logout</a>

生成 404 和此错误：

17:06:43,657 WARN [org.springframework.web.servlet.PageNotFound]（默认任务 27）在名称为 'springServlet'[= 的 DispatcherServlet 中找不到带有 URI [/Portal/logout] 的 HTTP 请求的映射17=]

无论我是否更改注销-url，这都是一样的。

我怀疑过滤器和 spring servlet 之间有些不兼容，但我不知所措。

你能帮忙吗？

我正在使用 spring-security 4.0.1

谢谢！

Answer 1

更改注销。像这样。

<a href='<c:url value="/j_spring_security_logout" />'>

Answer 2

我只需要使用一个表单来执行注销。像这样：

<c:url var="logoutUrl" value="/logout"/>
<form action="${logoutUrl}" method="post">
  <input type="submit" value="Log out" />
  <input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}"/>
</form>

这是因为 spring-security 的 CSRF 是默认启用的，注销必须通过 POST 使用 CSRF 令牌执行。
