Question

我正在使用Spring Boot和Ignite数据库

我仅创建了一个存储库，并且正在Pojo中设置数据以使用IgniteRepository保存

以下是Ignite与Spring的必需依赖项： Ignite版本:: 2.0.0

        <dependency>
            <groupId>org.apache.ignite</groupId>
            <artifactId>ignite-core</artifactId>
            <version>${ignite.version}</version>
        </dependency>

        <dependency>
            <groupId>org.apache.ignite</groupId>
            <artifactId>ignite-spring</artifactId>
            <version>${ignite.version}</version>
        </dependency>

        <dependency>
            <groupId>org.apache.ignite</groupId>
            <artifactId>ignite-indexing</artifactId>
            <version>${ignite.version}</version>
        </dependency>

        <dependency>
            <groupId>org.apache.ignite</groupId>
            <artifactId>ignite-spring-data</artifactId>
            <version>${ignite.version}</version>
        </dependency>
        <dependency>
            <groupId>com.h2database</groupId>
            <artifactId>h2</artifactId>
            <version>1.4.195</version>
        </dependency>

我在这里使用H2数据库依赖项，如果不使用它，则会收到另一个完全未知的错误。

IgniteConfiguration：

@Configuration
@EnableIgniteRepositories(excludeFilters = {
        @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = {
                TempRepository.class, GarageRepository.class, CarRepository.class,
                IncidentRepository.class, MachineRepository.class, MileageRepository.class, 
                LicenseRepository.class})
})
public class IgniteSpringConfiguration {

    @Bean
     public Ignite igniteInstance() {
      IgniteConfiguration cfg = new IgniteConfiguration();
      // Setting some custom name for the node.
      cfg.setIgniteInstanceName("eventInsights");
      // Enabling peer-class loading feature.
      cfg.setPeerClassLoadingEnabled(true);
      // Defining and creating a new cache to be used by Ignite Spring Data
      // repository.
      CacheConfiguration<Long, User> userCacheConfig = new CacheConfiguration<Long, User>("UserCacheConfig");

              // Setting SQL schema for the cache.
      userCacheConfig.setIndexedTypes(Long.class, User.class);

      cfg.setCacheConfiguration(new CacheConfiguration[] {
              userCacheConfig,

      });
      return Ignition.start(cfg);
     }
}

用户存储库界面：

@RepositoryConfig(cacheName = "UserCacheConfig")
public interface UserRepository extends IgniteRepository<User, Long>{

    User findByEmail(String email);
}

现在的主班：：

private static UserRepository userRepo;

     private static AnnotationConfigApplicationContext ctx;
public static void main(String[] args) {
      ctx = new AnnotationConfigApplicationContext();
      ctx.register(IgniteSpringConfiguration.class);
      ctx.refresh();

      userRepo= ctx.getBean(UserRepository.class);
      User user=new User();
      user.setEmail("george.paul01@xyz.com");
      user.setId(1L);
      user.setPassword("password");
      userRepo.save(user);

      User getUser=userRepo.findByEmail("george.paul01@xyz.com");

      if(getUser!=null) {
          System.out.println(getUser.getEmail());
          System.out.println(getUser.getPassword());
      }
      else {
          System.out.println("User name is not found");
      }

}

用户Pojo：

public class User implements Serializable
{
    private static final long serialVersionUID = 1L;

    public Long id;

    @QuerySqlField(index = true)
    private String password;

    @QuerySqlField(index = true)
    private String email;

    //getters and setters method here I am skipping in my question
}

运行后出现错误：

Answer 1

@RepositoryConfig未声明@Repository或@Component。猜猜它没有被组件扫描。试试：

@Component
@RepositoryConfig(cacheName = "UserCacheConfig")
public interface UserRepository extends IgniteRepository<User, Long>{
    User findByEmail(String email);
}

Spring无法创建已实现的IgniteRepository的bean
