Question

我正在使用：

Spring-data-neo4j 4.2.0-SNAPSHOT（也试过4.2.0.RC1）

自DATAGRAPH-939提交以来，我再也无法使用存储库了。

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

错误：

以下是我失败测试的一个例子：

@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？

由于

Answer 1

我不再遇到存储库问题。我现在正在使用带有Spring boot 1.5.1的SDN 4.2.0.RELEASE，我不再像SDN4.2.0文档中所解释的那样扩展GraphRepository。

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