部署到glassfish服务器时出现“ org.springframework.beans.factory.CannotLoadBeanClassException：找不到类…”

Question

部署/发布到Glassfish时收到此错误消息。 我正在使用Glassfish 4.0，Eclipse Kepler，Maven，Spring Security和PostGreSQL数据库。

今天早些时候一切正常，我可以发布任何错误。 然后希望解决其他问题，尽管我以前成功使用过托管Bean，但jsp页面无法找到ManagedBean类，但是我右键单击了我的项目并执行了“ build project”，然后右键单击project-> Maven- >更新项目，我在其他地方阅读过。 之后，错误出现。

我想类路径有问题，因为我注意到构建文件夹中缺少一些Java类，这可以在Eclipse的项目资源管理器中看到。 不幸的是，这是我的第一个JavaEE / Maven项目，所以我不知道如何解决这个问题。

来自Stacktrace的相关部分（出现几次）：

MyAuthenticationHandler类确实存在于src-folder的程序包“ util”中。 就像我之前说过的那样，之前一切正常，我没有更改代码。

使用Maven-> Update Project意味着项目属性根据pom.xml文件进行更新。 检查您的Java构建路径和部署程序集 。
