首先，我想说的是，我在讨论这个问题时找到了一些线索(即使是2020年的评论)，但它们都没有帮助我解决这个问题。

我正在将项目从java 8 (Oracle )迁移到java 11 (AdoptOpenJDK，java 11的最后一个版本)。

我使用的是maven、spring和jstl (除了不影响这个问题的其他依赖项之外)。

IDE是Intellij的想法

Spring发行版为2.2.4，jstl是这样导入的(在pom.xml中)：

代码语言：javascript
复制
<dependency>
    <groupId>jakarta.servlet.jsp.jstl</groupId>
    <artifactId>jakarta.servlet.jsp.jstl-api</artifactId>
    <version>1.2.7</version>
</dependency>

<dependency>
    <groupId>org.glassfish.web</groupId>
    <artifactId>jakarta.servlet.jsp.jstl</artifactId>
    <version>1.2.6</version>
</dependency>

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-taglibs</artifactId>
</dependency>

maven很容易安装这个应用程序，当我运行这个应用程序时，我得到了一个tomcat错误-

HTTP状态500 -内部服务器错误

当我查看控制台时，我发现了这个错误。

代码语言：javascript

问题是tomcat (或JSTL)想要运行以下代码

代码语言：javascript
复制
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>

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

当我注释掉前3行时(所以只存在Spring )，就会得到相同的错误(其他URI指向springframework.org.)。当我删除所有这些行时，我会收到一个错误，告诉我我使用了前缀c:它不存在，什么是预期的行为。

非常奇怪的是，我可以"ctrl + click“到"uri”xml param中指向正确的方向，如果第一行我被指向...m2/repository/org/glassfish/web/jakarta.servlet.jsp.jstl/1.2.6/jakarta.servlet.jsp.jstl-1.2.6.jar!/META-INF/c.tld，我认为这是正确的路径。

编辑：

当注释掉tomcat配置时，问题就消失了：

代码语言：javascript
复制
@Configuration
public class TomcatConfiguration {

    @Bean
    public TomcatServletWebServerFactory tomcatFactory() {
        return new CustomTomcatServletWebServerFactory();
    }

    static class CustomTomcatServletWebServerFactory extends TomcatServletWebServerFactory {

        @Override
        protected void postProcessContext(Context context) {
            ((StandardJarScanner) context.getJarScanner()).setScanManifest(false);
        }
    }

}

配置解决了这里提到的问题：Migrating from java 8 to 11 - jaxws-rt

有可能同时解决这两个问题吗？在启动应用程序时发出大量警告是非常烦人的。

java
spring-boot
jstl
taglib
jstl-functions

我找到的解决方案，似乎正在发挥作用，也许并不像我想的那么漂亮，所以如果有谁知道更好的解决方案，请随意发布您的解决方案。

通过显式选择导致tomcat不应该扫描的警告的jars，我从这个线程末尾提到的其他线程中增强了TomcatConfiguration。

代码语言：javascript
复制
@Configuration
public class TomcatConfiguration {

    @Bean
    public TomcatServletWebServerFactory tomcatFactory() {
        return new CustomTomcatServletWebServerFactory();
    }

    static class CustomTomcatServletWebServerFactory extends TomcatServletWebServerFactory {

        @Override
        protected void postProcessContext(Context context) {
            Set<String> pattern = new LinkedHashSet<>();

            pattern.add("jaxb*.jar");
            pattern.add("jaxws*.jar");
            pattern.add("ha-api*.jar");

            StandardJarScanFilter filter = new StandardJarScanFilter();
            filter.setTldSkip(StringUtils.collectionToCommaDelimitedString(pattern));

            ((StandardJarScanner) context.getJarScanner()).setJarScanFilter(filter);
        }
    }
}

此解决方案似乎有效( Tomcat不扫描导致问题的包，但可以扫描带有jstl支持的包以正确编译标记库)
