Spring 自 DATAGRAPH-939 以来，数据 neo4j 存储库无法正常工作

Question

我正在使用：

Spring-data-neo4j 4.2.0-SNAPSHOT（也尝试使用 4.2.0.RC1）

并且自 DATAGRAPH-939 提交以来，我无法再使用存储库。

@Repository
public interface MyEventRepository extends GraphRepository<Event> {}

错误：

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'myEventRepository': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'java.lang.Class<org.springframework.data.repository.Repository<?, ?>>' available: expected at least 1 bean which qualifies as autowire candidate.

这是我的失败测试示例：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class, classes = { SimpleTest.TestConfiguration.class })
public class SimpleTest {

    @Configuration
    @EnableNeo4jRepositories("com.nagra.ml.sp.cpm.core.repositories.test")
    public static class TestConfiguration {

        @Bean
        public org.neo4j.ogm.config.Configuration configuration() {
            org.neo4j.ogm.config.Configuration config = new org.neo4j.ogm.config.Configuration();
        config  .driverConfiguration()
                .setDriverClassName("org.neo4j.ogm.drivers.embedded.driver.EmbeddedDriver");
            return config;
        }

        @Bean
        public SessionFactory sessionFactory() {
            return new SessionFactory(configuration(), "com.nagra.ml.sp.cpm.model");
        }

        @Bean
        public Neo4jTransactionManager transactionManager() {
            return new Neo4jTransactionManager(sessionFactory());
        }
    }

    @Test
    public void test() {
        assertTrue(true);
    }
}

根据文档，声明存储库的方式似乎是正确的，我做错了吗？

谢谢

我不再有存储库问题。我现在正在使用 SDN 4.2.0.RELEASE 和 Spring boot 1.5.1，并且我不再按照 SDN4.2.0 文档中的说明扩展 GraphRepository。
