使用建立在网络上guildes,我做了简单的Spring引导2和Spring数据JPA 2应用程序。 春季启动JPA 2支持添加到Apache的Ignite只与2.7版本(现在它只有是avatilble每晚构建- 阿帕奇点燃2.7的发布日期 )。 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;
}}
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);
}}
上运行,我有以下异常:
[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]

我已经没有救*函数的声明在我的仓库。 只有getByUsername()。
- 如何解决这个错误?
- 我如何连接几个点燃节点,并与他们的工作像一个单一的数据库?
- 我有现有的PostgreSQL数据库。 我可以使用Ignite使用它们? (我在看点燃JDBC驱动程序,发现没有PostgreSQL驱动存在,onlyMySQL,SQL服务器,H2等的支持。但在他们当中普通的JDBC驱动程序)。
这里所描述的问题的语境: 其中分布式数据库我需要选择介质上的数据项目
