Spring Security并发控制

Question

我使用了spring security 3.0.7,我在我的项目中实现了并发控制.但它没有用.我用过

<security:session-management>
            <security:concurrency-control error-if-maximum-exceeded="true" max-sessions="1"/>
</security:session-management>

即使我尝试过弹簧安全参考的解决方案,但它没有成功.这是我的配置文件内容:

  <session-management session-authentication-strategy-ref="sas"/>
</http>

<beans:bean id="concurrencyFilter"
   class="org.springframework.security.web.session.ConcurrentSessionFilter">
  <beans:property name="sessionRegistry" ref="sessionRegistry" />
  <beans:property name="expiredUrl" value="/session-expired.htm" />
</beans:bean>

<beans:bean id="myAuthFilter" class=
   "org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter">
  <beans:property name="sessionAuthenticationStrategy" ref="sas" />
  <beans:property name="authenticationManager" ref="authenticationManager" />
</beans:bean>

<beans:bean id="sas" class=
 "org.springframework.security.web.authentication.session.ConcurrentSessionControlStrategy">
  <beans:constructor-arg name="sessionRegistry" ref="sessionRegistry" />
  <beans:property name="maximumSessions" value="1" />
</beans:bean>

<beans:bean id="sessionRegistry"
    class="org.springframework.security.core.session.SessionRegistryImpl" />

我得到以下异常:

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Filter beans '<myAuthFilter>' and '<org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter#0>' have the same 'order' value. When using custom filters, please make sure the positions do not conflict with default filters. Alternatively you can disable the default filters by removing the corresponding child elements from <http> and avoiding the use of <http auto-config='true'>.

有人可以帮忙解决这个问题吗？

如果您编写了UserPrincipaland UserPrincipalImpl（您自己的实现），则应该重写对象的equals()andhashCode()方法。
