Question

我有一个独特的问题。

我能够在运行JUnit测试时成功连接和管理实体，但是一旦我启动了我的实际应用程序，就会找不到指定的JDBC驱动程序oracle.jdbc.OracleDriver类。＆＃34;

令我困惑的是它在那里。运行JUnit测试时工作。

任何见解都表示赞赏！

我发现了我的问题。在我的pom.xml中，我有这个小片段

<dependency>
  <groupId>org.hibernate.common</groupId>
  <artifactId>hibernate-commons-annotations</artifactId>
  <version>4.0.1.Final</version>
  <classifier>tests</classifier>
</dependency>

分类器只能访问我的测试套件。删除分类器解决了问题。

<dependency>
  <groupId>org.hibernate.common</groupId>
  <artifactId>hibernate-commons-annotations</artifactId>
  <version>4.0.1.Final</version>
</dependency>
