春季新手 - 使用sec標記不起作用

嗨，我正在學習一個項目的Spring，並試圖教自己使用sec標籤來創建多個視圖，當不同的用戶登錄時。我一直遇到設置標籤的錯誤。春季新手 - 使用sec標記不起作用

這裏是我的JSP：

<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %> 

<html> 
<head> 
<title>Welcome</title> 
</head> 
<body> 
    <h1>Welcome</h1> 
    <security:authorize access="hasRole('admin')"> 
    Only admins can see the <a href="second">Second link</a> 
    </security:authorize> 
</body> 
</html>

這是給錯誤：無法找到的標籤庫描述符「http://www.springframework.org/security/tags」

這裏是我的xml：

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:security="http://www.springframework.org/schema/security"

      <security:intercept-url pattern="/servlet/Download" access="hasAnyRole('DOWNLOAD','PREMIUM_ACCOUNT')"/> 

      <security:intercept-url pattern="/**" access="isAuthenticated()"/> 
     </security:filter-security-metadata-source> 
    </property> 
</bean> 

<!-- webInvocationPrivilegeEvaluator necessary to use <sec:authorized url="xx"> --> 
<bean id="webInvocationPrivilegeEvaluator" class="org.springframework.security.web.access.DefaultWebInvocationPrivilegeEvaluator"> 
    <constructor-arg ref="filterSecurityInterceptor"></constructor-arg> 
</bean> 

</beans>

我已經來回切換「秒」到「安全」等一些事情，但無法讓它工作。預先感謝您的幫助。

搜索添加這種依賴在你的pom.xml的'找不到標籤庫descriptor' –

添加彈簧安全標籤庫，3.1.3.release.jar到您的項目的類路徑。

如果您正在使用Maven的，

<dependency> 
    <groupId>org.springframework.security</groupId> 
    <artifactId>spring-security-taglibs</artifactId> 
    <version>3.1.3.RELEASE</version> 
</dependency>
