私はカスタムリポジトリを使ってTTL(Time to Live)値のエンティティを保存しようとしています。私は多くの検索とオンラインのドキュメントを読んだことがありますが、まだ例外が発生しています。Spring Cassandra TTL保存のカスタムリポジトリ
ありがとうございました。次のように
Caused by: org.springframework.data.mapping.PropertyReferenceException: No property saveWithTTL found for type Task!
スニペットは、次のとおり
タスク(エンティティ):
@Table
public class Task {
@PrimaryKeyColumn(ordinal = 0, type = PrimaryKeyType.PARTITIONED)
private String uuid;
private Type type;
private Status status;
private String parentId;
private String body;
}
CassandraDbConfig:
@Configuration
@PropertySource(value = "classpath:cassandra.properties")
@EnableCassandraRepositories(repositoryBaseClass = TTLRepositoryCustomImpl.class)
public class CassandraDbConfig extends DefaultCassandraConfig {
}
TTLRepositoryCustom:
@NoRepositoryBean
public interface TTLRepositoryCustom<T> extends CassandraRepository<T> {
T saveWithTTL(T entity, Integer ttl);
}
TTLRepositoryCustomImpl:
public class TTLRepositoryCustomImpl<T> extends SimpleCassandraRepository<T, MapId>implements TTLRepositoryCustom<T> {
public TTLRepositoryCustomImpl(final CassandraEntityInformation<T, MapId> metadata,
final CassandraOperations operations) {
super(metadata, operations);
}
@Override
public T saveWithTTL(T entity, Integer ttl) {
WriteOptions options = new WriteOptions();
options.setTtl(ttl);
return operations.insert(entity, options);
}
}
TaskDbRepository:
@Repository
public interface TaskDbRepository extends TTLRepositoryCustom<Task> {
}
