我试图将嵌入式H2数据库包含到我的项目中，但是尝试运行该数据库时出现以下错误：
Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

这是我尝试实现Bean的方法：
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();
我该如何解决？谢谢大家。
最佳答案
在这里，您声明了Spring Boot JPA启动器。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
这样，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>
您无需声明在spring-config.xml文件中声明的所有内容。
此外，入门者还拉一些库。例如，
spring-boot-starter-data-jpa提供了Hibernate库。因此，您无需在pom.xml中指定它们。
最后，似乎也不需要在pom.xml中声明休眠版本，这可能不是一件好事，因为Spring Boot在声明的版本上可以很好地工作。如果不需要，请避免使用其他版本。
我认为您应该在Spring Boot上提供更多文档，因为在那里可以像使用Spring而不是Spring Boot一样构建应用程序。
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。
