在我在这里共享的代码中，线程“restartedmain”java.lang.reflect.invocationtargetexception中的异常由以下原因引起：java.lang.nullpointerexception我得到了新的错误。你能帮我做这个吗。

请共享并检查您的xyz-servlet.xml配置文件，您在其中定义了spring boot和hibernate信息。在看到您的错误（据我所知，这是您的xml文件中的hibernate异常）后，请检查您是否定义了driverclassname详细信息，请参阅下面的示例
检查这个数据库有四个属性driverclassname，url，username和password
