Spring 4 Spring Security 3.2.2没有定义名为“ springSecurityFilterChain”的bean

Question

我知道这个问题已经问了很多，但似乎没有一个答案对我真正有用。 在过去的两天里，我一直在与Spring Security相撞，并且运气为零。 该文档声称它非常容易安装，但是我不禁感到它缺少某些东西。

我的web.xml：

<web-app 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 http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
    <display-name>SpringProject</display-name>

    <!-- Spring Configuration Files -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath*:mvcDispatcher-servlet.xml
            classpath*:application-security.xml
        </param-value>
    </context-param>

    <!-- Spring Security Filters -->
    <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 Listeners -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- MVC Filter -->
    <servlet>
        <servlet-name>mvcDispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

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

</web-app>

而我的application-security.xml：

<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/security
        http://www.springframework.org/schema/security/spring-security-3.0.xsd">

    <global-method-security secured-annotations="enabled" />

    <http use-expressions="true">
        <form-login login-page="/login"
                    login-processing-url="/j_spring_security_check"
                    default-target-url="/view"
                    authentication-failure-url="/login?login_error=t" />
        <intercept-url pattern="/login" access="isAnonymous()" />
        <intercept-url pattern="/**" access="isAuthenticated()" />
    </http>

    <authentication-manager>
        <authentication-provider user-service-ref="userService" />
    </authentication-manager>

    <user-service id="userService">
        <user name="user" password="password" authorities="ROLE_ADMIN" />
    </user-service>

</beans:beans>

当我部署（到WAS8.0）并尝试进入登录页面时，出现以下错误：

com.ibm.ws.webcontainer.webapp.WebApp logServletError SRVE0293E: [Servlet Error]-[mvcDispatcher]: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'springSecurityFilterChain' is defined

如果我从以下位置更改web.xml：

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath*:mvcDispatcher-servlet.xml
            classpath*:application-security.xml
        </param-value>
    </context-param>

至：

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            WEB-INF/mvcDispatcher-servlet.xml
            WEB-INF/application-security.xml
        </param-value>
    </context-param>

我得到错误

[Servlet Error]-[mvcDispatcher]: org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/security]

我不知道是什么原因造成的，或者为什么Spring Security无法在这里工作。 真令人沮丧。 非常感谢任何帮助，谢谢！

尝试在您的web.xml中执行以下操作。

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

注意：

• WEB-INF目录不在类路径上。
• 默认情况下，DispatcherServlet查找WEB-INF / [servlet-name] -servlet.xml。
