对spring security用来作用权限做个记录

lym6520在测试的项目上引进了spring security 基于名称空间配置的安全架构，遇到一个问题，请指教下！
配置代码如下：

<?xml version="1.0" encoding="UTF-8"?>  
<!--  
  - 基于名称空间配置  
  -->  
<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-2.0.xsd  
                        http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-2.0.xsd">  
  
    <global-method-security secured-annotations="enabled">  
    </global-method-security>  
                                              
    <http access-denied-page="/error.jsp" session-fixation-protection="newSession" auto-config="true" path-type="ant" ><!--session-fixation-protection属性可以防止session固定攻击  -->  
       <!-- 权限入口的顺序十分重要，注意必须把特殊的URL权限写在一般的URL权限之前。 -->          
        <intercept-url pattern="/acegiTest.do" access="ROLE_SUPERVISOR"/>          
        <intercept-url pattern="/index.jsp" access="IS_AUTHENTICATED_REMEMBERED" />  
        <intercept-url pattern="/role1.jsp" access="ROLE_USER_1"/>  
        <intercept-url pattern="/role2.jsp" access="ROLE_USER_2"/>  
        <intercept-url pattern="/role3.jsp" access="ROLE_USER_3"/>  
        <intercept-url pattern="/**" access="IS_AUTHENTICATED_ANONYMOUSLY" />  
        <!--  
        x509认证  
        <x509 />   
        -->  
  
        <!-- All of this is unnecessary if auto-config="true"  
        <form-login />  
        <anonymous />  
        <http-basic />  
        <logout />  
        <remember-me /> -->  
        <form-login login-page="/login.jsp" default-target-url="/index.jsp" authentication-failure-url="/login.jsp?login_error=1" />  
        <anonymous key="cookie_key" username="ananoymous" granted-authority="IS_AUTHENTICATED_ANONYMOUSLY"/>          
        <logout invalidate-session="true" />  
        <!-- session并发控制  
        <concurrent-session-control max-sessions="1" exception-if-maximum-exceeded="true"/>  
        -->                
        <concurrent-session-control max-sessions="1" exception-if-maximum-exceeded="false" /><!-- exception-if-maximum-exceeded="true" 第二次登入失效 -->  
    </http>     
    
    <authentication-provider >   
             <password-encoder hash="md5"/><!-- 密码md5加密 -->      
        <jdbc-user-service data-source-ref="f3CenterDS"   
                users-by-username-query="select name as 'username',password,'true' from users where name = ?"  
                authorities-by-username-query="select name as 'username',authorities as 'authority' from authentication where name =?"   
                 />       
      
    </authentication-provider>  
      
</beans:beans>  

在代码中

authorities-by-username-query="select name as 'username',authorities as 'authority' from authentication where name =?"   

，如果数据库里分配多个权限给用户的话，用户登入系统就不能正常使用（不能访问），倘若只分配一个权限则可以正常访问，还请指教一二！！！

网友回答

如果lym6520把<jdbc-user-service/>放在缓存中，则不会出现这样的问题了！
如下

<user-service>  
            <user name="user" password="123" authorities="ROLE_SUPERVISOR, ROLE_USER_1"/>  
        </user-service>
