Question

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

时

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？

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现在可以正常运行：

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

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>
                <groupId>org.springframework</groupId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-core</artifactId>

            <exclusion>

我正在使用jetty 9（jetty-maven-plugin）以上情况无济于事。因此，将以下代码添加到WEB-INF / web.xml中，它就像魅力一样：

<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>

同样添加到jetty-context.xml的问题仍然存在：

<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>

找不到Spring Security taglib
