Question

我尝试通过弹簧启动2.6.0实现点燃2.1.0.RELEASE，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Maven Projet的，这是依赖项：

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

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，我不使用任何方法删除，所以为什么它给了我这个例外！版本冲突在某些地方吗？你有什么主意吗？

Answer 1

我也尝试对Ignite 2.6和Spring Boot 2.1.0进行相同操作，但IgniteReposities也不起作用。我很确定Ignite Spring Data 2.6模块不支持Spring 5。

作为解决方法，我在类Dao中使用SqlQuery访问数据，例如：

 array([['beef', 'bread', 'cane_molasses'],
       ['brassica', 'butter', 'cardamom']])

您需要使用ignite-spring-data_2.0代替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并点燃2.7.5

为什么我遇到IgniteRepository的deleteAll方法有问题？
