Spring BeanCreationException：通过工厂方法的Bean实例化失败嵌套异常

标签： spring hibernate spring-mvc spring-security autowired

我开始使用Spring，并尝试使用Security，Hibernate和Thymleaf构建应用程序。

我有这个错误让我困扰了好几天。

以下是日志：

如果您需要任何信息，请不要犹豫：）

2 个答案:

答案 0 :(得分：10)

Please make sure you have the correct packages to scan in your entity manager.

entityManagerFactory.setPackagesToScan( env.getProperty("entitymanager.packagesToScan")); are you sure the correct path has been set here. Not sure what entity manger is and are you setting the path to scan

答案 1 :(得分：1)

如果您的应用程序中定义了任何baseClass，请尝试使用

entityManagerFactoryBean.setPackagesToScan(new String[]{BaseEntity.class.getPackage().getName()});
