我有一个jsp，我正在使用两个spring选项卡库，即

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

如果我评论这两个我的jsp就执行得很好。但在其他情况下，它会抛出上述异常，这是我的异常堆栈跟踪。

我使用 spring 作为动态 Web 项目实现了一个应用程序，这不是一个 spring boot 应用程序，我的类路径中有 spring 3.2.2 jar，任何人都可以告诉我问题出在哪里吗？

最佳答案

Spring MVC 支持这两个 Spring 标签库。您需要下载 spring-webmvc-3.2.2.RELEASE.jar(以与当前版本保持一致)并将库复制到应用程序的 WEB-INF/lib 文件夹中。

编辑:这是工作原型(prototype)的 Maven 依赖关系树(带有 taglibs 和 Spring 3.2.2)。

demo:spring-mvc-demo:war:1.0-SNAPSHOT
 +- org.springframework:spring-webmvc:jar:3.2.2.RELEASE:compile
 |  +- org.springframework:spring-beans:jar:3.2.2.RELEASE:compile
 |  +- org.springframework:spring-context:jar:3.2.2.RELEASE:compile
 |  |  \- org.springframework:spring-aop:jar:3.2.2.RELEASE:compile
 |  +- org.springframework:spring-core:jar:3.2.2.RELEASE:compile
 |  |  \- commons-logging:commons-logging:jar:1.1.1:compile
 |  +- org.springframework:spring-expression:jar:3.2.2.RELEASE:compile
 |  \- org.springframework:spring-web:jar:3.2.2.RELEASE:compile
 |     \- aopalliance:aopalliance:jar:1.0:compile
 \- javax.servlet:javax.servlet-api:jar:3.0.1:provided

代码在 Jetty 9.2.17 上运行。您可以检查您的 Tomcat 实例的 lib 文件夹中是否有 JSTL。
