java - Spring mvc 应用程序没有出现错误-找不到属性'basePackageClasses'

问题描述

我有一个使用 spring 3.2.18 的标准 spring mvc 应用程序。它与其他一些 spring mvc 应用程序一起部署在 tomcat 上。

直到最近几年它都工作正常。现在调度程序 servlet 没有出现并给出以下错误。

我知道有一些弹簧初始化错误，但我无法弄清楚是什么。我试图为这个应用程序增加 spring 的日志记录级别，以及为部署它的 tomcat 服务器增加 log4j。但仍然没有运气。

在给出此错误的配置类之一中（使用调试计算），basepackageclasses 属性之前不存在，现在如果我用空括号 {} 添加它。它为下一堂课提供错误，依此类推。

在此应用程序的依赖项中可能会发生与 spring 相关的更改，但 spring 应该通知哪些 bean 有问题。它只是说-Attribute 'basePackageClasses' not found

我找到了这个链接，但固定在 4.2 https://github.com/spring-projects/spring-framework/issues/17769

任何帮助将不胜感激。我有点卡在这里。

解决方案

我们正在对一个包使用组件扫描，该包依赖于从类路径中删除的 jar。在添加回来之后一切正常。
