我正在尝试将一个嵌入式 H2 数据库包含到我的项目中，但是当我尝试运行它时出现以下错误:
Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

下面是我尝试实现该 bean 的方式:
AbstractApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"spring-config.xml"});
EntityManager entitymanager = emfactory.createEntityManager( );
entitymanager.getTransaction( ).begin( );
Employee employee = entitymanager.find( Employee.class, 1201 );
System.out.println( employee );
entitymanager.close();
emfactory.close();
我该如何修复它？提前谢谢大家。
最佳答案
在这里声明 Spring Boot JPA starter。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
有了这个，Spring Boot 可以自动配置 H2 数据库。您只需添加 H2 库:
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
</dependency>
你不需要声明你在spring-config.xml文件中声明的所有内容。
此外，初学者还拉了一些库。例如，Hibernate 库由 spring-boot-starter-data-jpa 提供。
因此，您不需要在 pom.xml 中指定它们。
最后，在 pom.xml 中声明 hibernate 版本似乎也不是必需的，而且可能不是一件好事，因为 Spring Boot 与其声明的版本配合良好。
如果不需要，应避免使用不同的版本。< br/>
我认为您应该在 Spring Boot 上编写更多文档，因为您在其中构建应用程序就像使用 Spring 而不是 Spring Boot 一样。
如果您不想使用 Spring Boot 功能，请不要使用 spring-boot-starter-data-jpa 和其他 Spring Boot 功能。
关于java - 如何嵌入H2数据库，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41577675/
