春季安全taglib不起作用

Question

我得到了问题..在我的WEB-INF/lib我得到的罐子，他们都是4.2.4版本的弹簧罐，但有两个例外：spring-security-config has 4.0.3和弹簧安全标记库太

弹簧调度 - servlet.xml中：

<beans xmlns="http://www.springframework.org/schema/beans" 
xmlns:context="http://www.springframework.org/schema/context" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" 
xsi:schemaLocation="

http://www.springframework.org/schema/beans/spring-beans.xsd 
http://www.springframework.org/schema/context 
http://www.springframework.org/schema/context/spring-context.xsd 
http://www.springframework.org/schema/mvc 
http://www.springframework.org/schema/mvc/spring-mvc.xsd"> 


<context:component-scan base-package="com.damian.controller" /> 
<mvc:annotation-driven /> 


<bean id="viewResolver" 
    class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
    <property name="prefix"> 
     <value>/WEB-INF/</value> 
    </property> 
    <property name="suffix"> 
     <value>.jsp</value> 
    </property> 

</bean> 

的web.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app 
xmlns="http://java.sun.com/xml/ns/javaee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> 
<display-name>OnlineShop</display-name> 

<servlet> 
    <servlet-name>spring-dispatcher</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
</servlet> 

<servlet-mapping> 
    <servlet-name>spring-dispatcher</servlet-name> 
    <url-pattern>/</url-pattern> 
</servlet-mapping> 

堆栈跟踪：

检查，如果你在你的classpath

<dependency> 
     <groupId>org.springframework.security</groupId> 
     <artifactId>spring-security-core</artifactId> 
     <version>4.0.3.RELEASE</version> 
    </dependency>
