未注入带有JPA2的Apache Ignite 2.7 IgniteRepository

问题描述 投票：0回答：1

使用基于Web的行会，我使用Spring Data JPA 2应用程序制作了简单的Spring Boot 2。 Spring Boot JPA 2支持仅在2.7版本中添加到Apache Ignite（现在仅在每晚构建时才可用-Apache Ignite 2.7 release date）。有代码片段：配置：

@Configuration

@ EnableIgniteRepositories公共类SpringDataConfig {

@Bean
public Ignite igniteInstance() {
    IgniteConfiguration config = new IgniteConfiguration();

    config.setIgniteInstanceName("ignite-1");
    config.setPeerClassLoadingEnabled(true);

    CacheConfiguration cache = new CacheConfiguration("usersCache");
    cache.setIndexedTypes(Integer.class, UserEntity.class);

    config.setCacheConfiguration(cache);
    Ignite ignite = Ignition.start(config);
    ignite.cluster().active(true);
    return ignite;
}}

存储库：

@RepositoryConfig(cacheName = "usersCache")
public interface UsersRepository extends IgniteRepository<UserEntity, Integer> {
    UserEntity getByUsername(String username);
}

和服务：

    @Service
public class UserServiceImpl implements UserService {
    @Autowired
//    UsersRepository repository;
    ApplicationContext context;

    @Override
    public UserEntity getByUsername(String username) {
        return context.getBean(UsersRepository.class).getByUsername(username);
    }}

运行时，我有以下例外：

[09:59:18] Ignite node started OK (id=8497f64c, instance name=ignite-1)
[09:59:18] Topology snapshot [ver=1, locNode=8497f64c, servers=1, clients=0, state=ACTIVE, CPUs=4, offheap=1.5GB, heap=1.7GB]
..

我的存储库中没有save *函数声明。仅getByUsername（）。

  1. 如何解决该错误？
  2. 我如何连接几个点火节点并像单个数据库一样与他们合作？
  3. 我有现有的PostgreSQL数据库。我可以将它们与Ignite一起使用吗？ （我正在查看ignite JDBC驱动程序，发现不存在PostgreSQL驱动程序，仅支持MySQL，SQL Server，H2等。但是有普通的JDBC驱动程序其中]）。

    4. 此处描述的问题上下文：Which distributed database I need to choose for medium data project

我有同样的问题。当我们尝试同时使用JPA存储库和Ignite存储库时，Spring会将Ignite存储库视为JPA存储库，因为它也是从Repository接口扩展而来的。它尝试将IgniteRepository实现为JpaRepository，但由于使用的实体不是Jpa实体，因此将失败。

因此，我们需要从JpaRepository配置中排除IgniteRepository接口。为此，您可以在@SpringBootApplication注释下面添加注释。
