spring-boot - 为什么我在使用 IgniteRepository 的 deleteAll 方法时遇到问题？

Question

我尝试使用 spring boot 2.1.0.RELEASE 实现 ignite 2.6.0，但是当我全新安装代码时，出现以下异常:

name clash: deleteAll(java.lang.Iterable<ID>) in org.apache.ignite.springdata.repository.IgniteRepository and deleteAll(java.lang.Iterable<? extends T>) in org.springframework.data.repository.CrudRepository have the same erasure, yet neither overrides the other

这是关于一个 Maven 项目，这里是依赖项:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-jpa</artifactId>
    </dependency>
</dependencies>

点燃配置类

@Configuration
@EnableIgniteRepositories
public class IgniteConfig {
@Bean
public Ignite igniteInstance() {
  IgniteConfiguration config = new IgniteConfiguration();

  CacheConfiguration<String, MyEntity> cacheMyEntity = new CacheConfiguration<>("MyEntityCach");
  cacheMyEntity.setIndexedTypes(String.class, MyEntity.class);

  CacheConfiguration[] cacheConfiguration= new CacheConfiguration[] {cacheMyEntity};
  config.setCacheConfiguration(cacheConfiguration);
  return Ignition.start(config);
}
}

存储库

@RepositoryConfig(cacheName = "MyEntityCach")
public interface EntityRepository extends IgniteRepository<MyEntity, String>{}

实体

@Getter
@Setter
@Builder
public class MyEntity implements Serializable{

@QuerySqlField(index = true)
private String id;

@QuerySqlField()
private String label;

@QuerySqlField()
private Long number;

@QuerySqlField(index = true)
private Long idParent
}

好吧，我不使用任何方法来删除，所以为什么它给了我这个异常(exception)!这是版本的冲突吗？你有什么想法吗？

你需要使用 ignite-spring-data_2.0 而不是 ignite-spring-data:

    <dependency>
        <groupId>org.apache.ignite</groupId>
        <artifactId>ignite-spring-data_2.0</artifactId>
        <version>${ignite.version}</version>
    </dependency>

这适用于 spring-boot 2.1.6.RELEASE 和 ignite 2.7.5
