我有一个使用Spring数据JPA的以下Spring引导项目。我休息控制器注释与以下annotations-:Spring引导 - 为什么手动配置Hibernate时需要排除?
@SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
@ComponentScan({ "com.foo.bar"})
public class RESTService {
我的问题是,为什么在@EnableAutoConfiguration需要排除参数?如果我没有启动应用程序排除我得到以下者除外:
Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Tomcat.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.tomcat.jdbc.pool.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).
现在我手动从我的项目中配置Hibernate的。
我的推理是,由于Spring Boot会在类路径上看到spring数据,它会尝试自动配置JDBC和Hibernate JPA。但为什么不试图自动配置Mongo或任何其他数据库解决方案?
有人能帮我理解这里发生了什么吗?

请问您可以发布您的pom文件吗? @SpringBootApplication应该放在主应用程序类中。 RESTService类是您的主类吗? – MrKiller21
@ MrKiller21添加了我的POM文件 –
Spring Boot将只配置它在类路径中找到的内容。如果你没有mongo为什么需要配置mongo。 –
