tags - 无法为标签“sec:authorize”加载标签处理程序类“org.springframework.security.taglibs.authz.AuthorizeTag”

Question

我正在使用 Netbeans 7.1.2 开发 Spring MVC 应用程序。有安全问题。当我想为未经授权的当前用户隐藏页面上的某些操作时。这是具有安全性的 pom 的一部分：

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-web</artifactId>
    <version>3.0.6.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>3.0.6.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-taglibs</artifactId>
    <version>3.0.6.RELEASE</version>
    <scope>compile</scope>

</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>
    <version>3.0.6.RELEASE</version>
</dependency>

这是jsp的一部分：

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

所以我包含了所需的依赖项，包含了 taglib，但得到了下一个错误

HTTP Status 500 - /WEB-INF/views/showEmployees.jsp (line: 56, column: 21) Unable to load tag handler class "org.springframework.security.taglibs.authz.AuthorizeTag" for tag "sec:authorize"
