Question

我不确定发生了什么，但我无法使用 eclipse 部署我的项目...它在几天前工作，现在我不断收到相同的错误

任何帮助将不胜感激......这就是我得到的:

Answer 1

ContextLoaderListener 是 spring-web 的一部分，所以首先它应该在您的 web 项目的“Maven Dependencies”下可见(当然您的 web 项目必须是带有 maven 的动态 web 项目性质)。

对于 Eclipse“Kepler”，我们遇到了一个问题，即在执行“Maven->Update Project”之后，服务器启动的依赖项解析丢失了。

右键单击 Web 项目 -> 属性 -> 部署程序集进行检查。 Maven 依赖项应该在源列中，并以 WEB-INF/lib 作为目标。否则，您必须使用“Add..->Java Build Path Entries -> Maven Dependencies”来添加它。
