从数据库或属性获取Spring Security拦截URL

希望这是非常简单的，存在的，而且我正在俯视我的鼻子下面的东西。我知道我可以通过注释限制访问：

@Secured({"ROLE_ADMIN"})

或通过配置：

<security:intercept-url pattern="/**" access="ROLE_USER, ROLE_ADMIN, ROLE_SUPER_USER" />

我希望从数据库中获取身份验证规则，例如：

<security:intercept-url provider="authProvider"/>
<bean id="authProvider" class="AuthProviderImpl">
    <property name="userDetailsService" ref="userDetailsService"/>
</bean>

最坏的情况是，必须有一种通过属性文件填充的方法吗？

/admin/**=ROLE_ADMIN

/**=ROLE_USER

<security:intercept-url props="classpath:urls.properties"/>

等等

请告诉我这存在，否则我的大脑会爆炸！！！Grails的spring-security插件开箱即用，所以我知道这必须存在。请不要让我的大脑爆炸！！！

弄清楚了…

您必须提供一个自定义org.springframework.security.intercept.web.FilterSecurityInterceptor并提供objectDefinitionSource：

<bean id="filterSecurityInterceptor" class="org.springframework.security.intercept.web.FilterSecurityInterceptor">
    <security:custom-filter before="FILTER_SECURITY_INTERCEPTOR" />
    <property name="authenticationManager" ref="authenticationManager" />
    <property name="accessDecisionManager" ref="accessDecisionManager" />
    <property name="objectDefinitionSource">
        <value>
            CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON
            PATTERN_TYPE_APACHE_ANT
            /**login.html=IS_AUTHENTICATED_ANONYMOUSLY
            /user/**=ROLE_ADMIN
        </value>
    </property>
</bean>

我想我将使用FactoryBean：

public class RequestMappingFactoryBean implements FactoryBean {
    private final static String EOL = System.getProperty("line.separator");
    public Object getObject() throws Exception {
        StringBuffer sb = new StringBuffer();
        sb.append("CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON");
        sb.append(EOL);
        sb.append("PATTERN_TYPE_APACHE_ANT");
        sb.append(EOL);
        sb.append("/**login.html=IS_AUTHENTICATED_ANONYMOUSLY");
        sb.append(EOL);
        sb.append("/user/**=ROLE_ADMIN");
        return sb.toString();
    }
    @SuppressWarnings("unchecked")
    public Class getObjectType() {
        return String.class;
    }
    public boolean isSingleton() {
        return true;
    }
}

将其传递给DAO等

<bean id="filterSecurityInterceptor" class="org.springframework.security.intercept.web.FilterSecurityInterceptor">
    <security:custom-filter before="FILTER_SECURITY_INTERCEPTOR" />
    <property name="authenticationManager" ref="authenticationManager" />
    <property name="accessDecisionManager" ref="accessDecisionManager" />
    <property name="objectDefinitionSource" ref="requestMappings" />
</bean>
<bean id="requestMappings" class="RequestMappingFactoryBean" />
