【问题描述】：

我正在尝试将 Spring JPA 与 MongoDB 集成。我的意图是从 mongo DB 中检索数据。注入我的存储库时出现以下错误。

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mongoService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.org.coop.society.data.mongo.repositories.MaterialMasterRepository com.org.coop.security.service.MongoService.materialMasterRepository; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'materialMasterRepository': Invocation of init method failed; nested exception is java.lang.AbstractMethodError

下面给出我的配置sn-p。

TestMongoDBConfig.java

@Configuration
@EnableMongoRepositories(basePackages = {"com.abc.data.mongo.repositories"})
@ComponentScan(basePackages = "com.abc")
@PropertySource("classpath:applicationTest.properties")
public class TestMongoDBConfig extends AbstractMongoConfiguration {
@Autowired
private Environment env;

 @Override
    protected String getDatabaseName() {
        return "retail";
    }

    @Override
    @Bean
    public MongoClient mongo() throws Exception {
        MongoClient client = new MongoClient("localhost", 27017);
        return client;
    }

    @Override
    protected String getMappingBasePackage() {
        return "com.abc.data.mongo.entities";
    }

    @Bean
    public MongoTemplate mongoTemplate() throws Exception {
        return new MongoTemplate(mongo(), getDatabaseName());
    }
}

MaterialMaster.java 在 com.abc.data.mongo.entities 包中

@Document(collection = "materialMaster")
public class MaterialMaster {

@Id
private Long materialId;

@Field
private String name;

MaterialMasterRepository.java 在 com.abc.data.mongo.repositories 包中

public interface MaterialMasterRepository extends MongoRepository<MaterialMaster, Long> {
}

MongoService.java 在 com.abc.service 包中

@Service
public class MongoService {

    @Autowired
    private MaterialMasterRepository materialMasterRepository;

    public void getMaterials() {
        List<MaterialMaster> materials = materialMasterRepository.findAll();

        System.out.println(materials);
    }
}

Junit 类如下所示

@RunWith(SpringJUnit4ClassRunner.class)
@ComponentScan(basePackages = "com.abc")
@ContextHierarchy({
     @ContextConfiguration(classes={TestMongoDBConfig.class})
})
public class ModuleWSTest {
    @Autowired
    private MongoService mongoService;
    @Test
    public void testModule() {

        mongoService.getMaterials();
    }
}

我已经尝试了所有可能的更改（据我所知），但没有运气。非常感谢任何帮助。

【解决方案1】：

错误信息有点混乱。我使用的是最新的 spring-data-mongodb (1.8.4.RELEASE)。一旦我将依赖项降级到 1.6.0.RELEASE ，上面的配置就开始工作了。
