在 Spring Boot 中排除 Hibernate 不起作用

Question

我正在尝试在没有休眠的情况下启动 JUnit 测试。我的应用程序类：

@SpringBootApplication(exclude = { HibernateJpaAutoConfiguration.class, JpaRepositoriesAutoConfiguration.class,
    DataSourceAutoConfiguration.class, JpaBaseConfiguration.class, WebMvcAutoConfiguration.class })
@ComponentScan("my.base.package")
public class TestContext {

  public static void main(String[] args) {
    SpringApplication.run(TestContext.class, args);
  }

}

如您所见，我排除了越来越多的东西，但总是出现同样的错误。我的测试：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = TestContext.class)
public class TestMail {
    @Autowired
    private Component c;

    public void setC(Component c) {
        this.c = c;
    }

    @Test
    public void test() {
       ...
    }

}

当我开始测试时，Hibernate 将被配置并失败：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private javax.sql.DataSource org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration.dataSource; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration$NonEmbeddedConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$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 (the profiles "dev" are currently active).

因此，仅启动应用程序或作为测试的上下文也会启动休眠配置。我做错了什么？

编辑： 只有：

@SpringBootApplication(exclude = { HibernateJpaAutoConfiguration.class, JpaRepositoriesAutoConfiguration.class}) 

在我尝试使用实际的休眠内容之前不会抛出任何异常。但是它正确地构建了数据库...

编辑2： 问题是具有 @EnableJpaRepositories 的自定义配置类。这似乎也是不可能的，因为使用 @Component 注释的具有自动装配存储库的 Bean 将失败，因为无法创建 bean。

尝试将 DataSourceTransactionManagerAutoConfiguration.class 添加到排除列表。当我需要从自动配置中排除休眠时，这对我有用。

您是否尝试过使用 --debug 开关启动测试？这将报告自动配置 (https://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-auto-configuration.html)。
