spring - "j_spring_security_check"没有http自动配置直接配置spring security后找不到

Question

我正在尝试使用 FilterChainProxy 将 Spring Security 配置从 HTTP 命名空间转换为直接配置。在转换之前，HTTP 命名空间一切正常。但是用FilterChainProxy用几个元素替换元素后，登录系统时出现“j_spring_security_check not found”错误。我试图用“/app/j_spring_security_check”更改全部或部分“/j_spring_security_check”，但仍然无法成功登录。

我的环境:
AppFuse 2.1 与 Spring MVC、iBatis、Spring Security 3.0.7、tuckey urlrewrite 3.2.0、Spring 3.0.6
Windows 7的
JDK 1.5.0_17
Maven 2.2.1
apache-tomcat-6.0.32

Security.xml(转换前，一切正常。)

Answer 1

最后我自己修好了。

在调试没有Spring安全命名空间的SecurityContextPersistenceFilter的doFilter()方法时，发现contextBeforeChainExecution和contextAfterChainExecution为null。但是在调试带有命名空间的程序时，它们的值都是关于匿名的。

我在 securityMetadataSource 中添加了“/j_spring_security_check”和“/login”以及“IS_AUTHENTICATED_ANONYMOUSLY”访问权限，如下所示，问题解决了。

    <beans:property name="securityMetadataSource">
        <filter-security-metadata-source>
            <intercept-url pattern="/j_spring_security_check" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
            <intercept-url pattern="/login" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
            <intercept-url pattern="/app/admin/**" access="ROLE_ADMIN"/>
            <intercept-url pattern="/app/passwordHint*" access="ROLE_ANONYMOUS,ROLE_ADMIN,ROLE_USER"/>
            <intercept-url pattern="/app/signup*" access="ROLE_ANONYMOUS,ROLE_ADMIN,ROLE_USER"/>
            <intercept-url pattern="/app/**" access="ROLE_ADMIN,ROLE_USER"/>
        </filter-security-metadata-source>
    </beans:property>
