【问题描述】：
我已经编写了一个 AWS Lambda 函数（像往常一样实现了 handleRequest，没有 db connect 的东西它可以正常工作），它实际上假设连接到一个亚马逊托管的 Oracle 数据库。
同样，我添加了 Hibernate Util 和相关配置文件以连接到数据库。这样在调用 AWS Lambda 函数时，就会将特定记录插入到数据库中。
但我收到以下错误，这里有什么我遗漏的吗？
{
"errorMessage": "Could not initialize class com.exercise.HibernateUtil",
"errorType": "java.lang.NoClassDefFoundError",
"stackTrace": [
"com.exercise.CurrentTime.handleRequest(CurrentTime.java:34)",
"sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)",
"sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)",
"sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)",
"java.lang.reflect.Method.invoke(Method.java:497)"
]
}
编辑
我发现没有添加 hibernate.cfg.xml ，后来我添加了所有必需的文件，但最后它给出了以下问题[在我的桌面上一切正常]：
我的问题是，我们是否有任何示例将基于休眠的包上传为 lambda 函数或 AWS lambda 服务意味着最小逻辑功能。

【问题讨论】：
-
表示您部署的 Lambda 函数中未包含一个类。您没有将该类正确打包到部署中。
-
我的错，我做了所有事情来拒绝 AWS lambda 函数，因为我是这个领域的新手，所以错过了一些安全组配置和其他一些亚马逊特定的东西，这个问题得到了解决。
-
你解决了吗？显示您的 pom.xml 示例
-
@Dynamic ，我删除了 Hibernate 的东西，并使用普通的 JDBC 方式将 lambda 函数与 DB 连接起来。关注以下网址：mkyong.com/jdbc/connect-to-oracle-db-via-jdbc-driver-javatutorialspoint.com/jdbc/preparestatement-object-example.htm
