当我将 Spring 与 Webserivces 集成应用程序部署到 Tomcat 服务器中时,在服务器启动时出现以下错误。
java.lang.NoClassDefFoundError: Lorg/springframework/web/multipart/MultipartResolver;
我确信我已在 pom.xml 中添加了所有必需的依赖项

并注意 spring 依赖项中没有版本冲突(我仅使用 Spring-3.0.5)。我不知道为什么会发生错误,你有什么想法吗?
MultipartResolver
类包含在spring-web JAR中。由于某些其他依赖项,Maven 可能包含错误版本的 spring-web。我会尝试在 POM 中明确声明 spring-web
版本 3.0.5.RELEASE
作为依赖项。
感谢所有我解决了问题。我刚刚更新了 pom.xml (由于 spring-asm 2.X 版本是在类路径中设置的,可能是由于其他一些相互依赖性而引发的)

当将旧代码从 spring 5 移动到 6 时,我几乎遇到了类似的异常,org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.springframework.web.multipart.commons.CommonsMultipartResolver]。 这有帮助 org.springframework.web
