Question

当我尝试在Hibernate教程（https://docs.jboss.org/hibernate/orm/5.0/quickstart/html/hibernate-tutorials.zip）中运行该示例时，由于ClassNotFound异常而失败。我检查了依赖项，并且类（CoreMessageLogger）可用。

有人可以帮忙解决这个问题吗？提前谢谢。

我正在使用JDK 1.8 update 66和Maven 3.3.9。

例外是：

Answer 1

您错过了jta.jar。尝试在您的lib文件夹中添加jta.jar或在您的pom.xml中添加此jar的依赖项。这包含javax / transaction / SystemException

Answer 2

在pom.xml中添加依赖项。它应该可以正常工作

  <dependency>
      <groupId>javax.transaction</groupId>
      <artifactId>jta</artifactId>
      <version>1.1</version>
  </dependency>
