spring+spring-mvc+spring-security配置问题

[sinat_35304816]

web.xml的配置

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

按找上面的配置，进入登录页面（/admin/login），输入用户和密码点击登录后，警告: No mapping found for HTTP request with URI [/j_spring_security_check] in DispatcherServlet with name 'spring-mvc'，报404错误。
如果spring-mvc的<url-pattern>/</url-pattern>改为<url-pattern>/*</url-pattern>，结果连登录页面都进不去了，警告: No mapping found for HTTP request with URI [/admin/login] in DispatcherServlet with name 'spring-mvc'。

提示不是说j_spring_security_check这个页面没找到对应的mapping吗？ controller里有没有写？
