添加"sping-secity-taglibs"后仍然在jsp中出错：找不到Spring Security标签的标签库描述符

Question

最初，在添加taglib之后，我的jsp出现了错误”http://www.springframework.org/security/tags“，然后我在谷歌上搜索，发现spring security taglibs jar不见了，然后我在pom.xml文件中添加了jar/依赖项。但我还是遇到了同样的错误。知道发生了什么吗。

jsp代码，

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="security" uri="http://www.springframework.org/security/tags" %>
    <nav class="navbar navbar-inverse navbar-fixed-top">
      <div class="container-fluid">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>
          <a class="navbar-brand" href="#" style="margin-bottom: 12px"> <img src="${pageContext.servletContext.contextPath}/resources/images/bluestar-logo.jpg" class="img-responsive" alt="Cinque Terre"></a>
          <div style="margin-left:700px">
            <h3>Decision Support System for VRF</h3>
        </div> 
        </div>

        <!-- <security:authorize ifAnyGranted="ROLE_USER"> -->
            <div id="navbar" class="navbar-collapse collapse">
              <ul class="nav navbar-nav navbar-right">
                <li><a href="#"><span class="glyphicon glyphicon-log-out" style="color:#fff"></span></a></li>
              </ul>
            </div>
        <!-- </security:authorize> -->

      </div>
    </nav>

在这一行中，我遇到了一个错误

Answer 1

对于Spring MVC，我通过添加

spring-security-taglibs.jar

将文件存入lib文件夹。确保您使用相同的版本与其他安全罐

Answer 2

我想这个问题已经回答过了，下面是来自Spring Security的解决方案，JSP Tag Lib Error

<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %>
works for me, with these

 <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-config</artifactId>
            <version>${spring.security.version}</version>
            <scope>${defaultScope}</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-core</artifactId>
            <version>${spring.security.version}</version>
            <scope>${defaultScope}</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-web</artifactId>
            <version>${spring.security.version}</version>
            <scope>${defaultScope}</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-taglibs</artifactId>
            <version>${spring.security.version}</version>
            <scope>${defaultScope}</scope>
        </dependency>
where spring.security.version = 3.1.4.RELEASE.

And make sure you have included the correct jst jar.
