找不到Spring Security taglib

Question

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

我会收到以下错误:

The absolute uri: http://www.springframework.org/security/tags cannot be resolved in either web.xml or the jar files deployed with this application

但是我的/ lib文件夹中有spring-security-taglibs-3.1.3等.有谁知道我还缺少什么？

Answer 1

添加此依赖项为我修复了它(使用3.1.X.RELEASE):

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-taglibs</artifactId>
    <version>${your-version}</version>
</dependency>

taglib现在可以正常工作:

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