Javax.servlet.ServletException
我刚刚加入了一个新团队，我正在尝试使用 GWT 在 eclipse 中运行他们的项目。我知道代码没问题，但我不断收到类似的错误。

您知道是否存在可能导致此问题的插件或兼容性问题？假设代码本身没问题，因为我正在尝试运行稳定版本。感谢您的任何帮助。
I've just come onboard with a new team and I am trying to run their project within eclipse using GWT. I know the code is fine, but I keep getting a similar error.

Is there a plugin or compaibilty issue that you know of that could be causing this? Assuming the code itself is fine as I'm trying to run a stable release. Thanks for any help.

看起来您的项目缺少 slf4j jar。
Looks like your project is missing slf4j jar(s).
这是一个 Spring bean 配置错误：检查所有必需的 Spring 定义是否正确以及 Spring 上下文 xml 文件是否位于正确的位置。
It is a Spring bean configuration error: check that all the necessary Spring definitions are correct and that the Spring context xml files are in the right places.
如果您使用 Eclipse 并且 Web 应用程序有依赖项目，则需要将它们添加到工作区并打开它们。
If you are using Eclipse and have dependent projects to your web application, you need to add them to your workspace and have them open.
