servlet ctakes-rest-service 的 Servlet.init() 抛出异常

Question

我是编程初学者。 我试图在 Windows 版本中运行 ctakes API，但是当我试图通过 Postman 获得响应时出现以下错误。 谁能指导我采取正确的步骤？ 提前致谢。

这可能是过程中某个部分的 SQL 配置问题，特别是如果密码与其中一个配置文件中 root 帐户的预期密码不同。

请尝试https://github.com/GoTeamEpsilon/ctakes-rest-service/issues/43看看这个非常相似但不完全相同的堆栈跟踪是否可以帮助您。
