Spring自动装配失败

这个问题与我早上问过的问题有关。

在上面的答案发布后，我无法解决。

所以我尝试使用测试用例来更好地理解并简化

我用测试用例简化了上面的问题。

这里我试图将文档放入mongo db。

这是我测试的。

 @Document(collection = "test")
 public class Test implements Serializable {

 private String source = null;
 private long systemTime;
 }

测试案例 

    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(classes = { MongoConfiguration.class})
   public class ApplicationTests {

  @Test
   public void thatDocumentRepositoryWorks() {

     Test tt= new Test();
    tt.setSystemTime(System.currentTimeMillis());
    tt.setSource("twitter");
    stagingDocumentRepository.save(payLoad);
 }
}

StagingDocumentRepository 

 @Repository
 public interface StagingDocumentRepository extends
  MongoRepository<CIPPayload, Serializable> {

  }

输出：

应使用配置类文件上的@Enable{type}Repositories注释（在本例中为@EnableMongoRepositories）自动发现Spring存储库（对于Java配置），该文件会自动为这些接口创建代理实例。你不需要@Repository注释。这不符合你的想法。

只需使用它注释MongoConfiguration即可。来自the reference guide

  

如果您更愿意使用JavaConfig，请使用@EnableMongoRepositories注释。注释带有与命名空间元素完全相同的属性。如果未配置基本软件包，则基础结构将扫描带注释的配置类的软件包。

@Configuration
@EnableMongoRepositories
class ApplicationConfig extends AbstractMongoConfiguration {

  @Override
  protected String getDatabaseName() {
    return "e-store";
  }

  @Override
  public Mongo mongo() throws Exception {
    return new MongoClient();
  }

  @Override
  protected String getMappingBasePackage() {
    return "com.oreilly.springdata.mongodb"
  }
}

如果您有兴趣/好奇，请参阅the github readme作为AbstractMongoConfiguration的额外帮助资源和源代码
