错误：元素前缀“安全”，“安全性：认证供应商”未绑定

Question

这里是我的应用程序security.xml文件：

<?xml version="1.0" encoding="UTF-8"?> 
<!-- 
    - Sample namespace-based configuration 
    - 
    - $Id: applicationContext-security.xml 3019 2008-05-01 17:51:48Z luke_t $ 
    --> 
<beans:beans xmlns="http://www.springframework.org/schema/security"

xsi:schemaLocation="

    <intercept-url pattern="/login.jsp" access="IS_AUTHENTICATED_ANONYMOUSLY" /> 

    <!-- Restrict access to ALL other pages -->

    <intercept-url pattern="/admin/*.html" access="ROLE_ADMIN" /> 
    <intercept-url pattern="/manager/*.html" access="ROLE_MANAGER" /> 
    <intercept-url pattern="/**.html" access="ROLE_USER,ROLE_ADMIN, ROLE_MANAGER" /> 
    <!-- Set the login page and what to do if login fails --> 
    <form-login login-page="/login.jsp" authentication-failure-url="/login.jsp?login_error=1" default-target-url="/user/userdashboard/dashboard.html" /> 
    <logout logout-success-url="/login.jsp"/> 
</http> 

<!--

--> 
    **<security:authentication-provider> 
     <jdbc-user-service data-source-ref="dataSource" /> 
    </security:authentication-provider>** 
</beans:beans> 

一切工作正常，但我得到这个元素“security：authentication-provider”的“前缀”安全性的奇怪错误未被绑定。“即使我提供了结束标记。任何人有任何关于如何解决这个问题的线索？

既可以使用 “安全” 的所有元素，通过使用proper namespace：

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:security="http://www.springframework.org/schema/security" 
    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-3.0.xsd 
      http://www.springframework.org/schema/security 
      http://www.springframework.org/schema/security/spring-security-3.0.3.xsd"> 
    ... 
</beans> 

然后使用 “安全” 随处可见，比如：

<security:global-method-security secured-annotations="enabled"> 
</security:global-method-security> 

或者完全地摆脱它：

... 
<authentication-provider> 
     <jdbc-user-service data-source-ref="dataSource" /> 
    </authentication-provider> 
... 

因为您配置了默认命名空间xmlns="http://www.springframework.org/schema/security"
