【中文标题】找不到 Spring Security 标记库【英文标题】:Spring Security taglib cannot be found 【发布时间】:2013-04-12 13:33:12 【问题描述】:当我把<%@ 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?
【问题讨论】:
你在 web.xml 上启动 SpringSecurity 监听了吗? 【参考方案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>
标签库现在可以正常工作了:
<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %>
【讨论】:
是的,但我应该选择哪个版本?【参考方案2】:确保包含以下依赖项
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
<version>3.1.2.RELEASE</version>
<exclusions>
<exclusion>
<artifactId>spring-aop</artifactId>

【参考方案3】:我正在使用 jetty 9 (jetty-maven-plugin) 以上帮不上忙。所以将下面的代码添加到 WEB-INF/web.xml 中,它就像魅力一样工作:
<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
<init-param>
<param-name>fork</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>xpoweredBy</param-name>
<param-value>false</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.jsp</url-pattern>
<url-pattern>*.jspf</url-pattern>
<url-pattern>*.jspx</url-pattern>
<url-pattern>*.xsp</url-pattern>
<url-pattern>*.JSP</url-pattern>
<url-pattern>*.JSPF</url-pattern>
<url-pattern>*.JSPX</url-pattern>
<url-pattern>*.XSP</url-pattern>
</servlet-mapping>
另外添加到jetty-context.xml中问题依旧:
<Configure class="org.eclipse.jetty.maven.plugin.JettyWebAppContext">
<Call name="setAttribute">
<Arg>org.eclipse.jetty.server.webapp.WebInfIncludeJarPattern</Arg>
<Arg>^$|.*/spring-[^/]*\.jar$|</Arg>
</Call>
</Configure>

以上是关于找不到 Spring Security 标记库的主要内容,如果未能解决你的问题,请参考以下文章

添加“spring-security-taglibs”后jsp中仍然报错:找不到spring security标签的标签库描述符
