简介：我有两个项目，

quizManager核心

，和

quizManager api

。正如名称所示，

quizManager core

处理所有工作，并且

quizManager api

将服务作为restapi公开

核心项目是Maven，使用derby数据库和Spring框架。这些测试使用内存数据库和生产数据库都能完美地工作。

api

项目也是Maven，它使用springmvc来处理api请求和响应

问题是：

api

项目在使用核心项目中指定的内存中数据库时运行良好。但是

java.sql.SQLException:找不到适合jdbc的驱动程序：derby://localhost:1527/QuizManager;使用生产数据库时会引发create=true

我试过的是：1。在API项目中包括derby包（derby和derbyClient）。2.在

applicationContext.xml

中添加bean，就像在核心项目中一样

我无法从项目的哪个部分确定这个bug正在发生

quizManager core/pom.xml
