这是我得到的响应...点燃节点启动之后。
这是我使用过的POJO类，如果我改用Entity类，则会出现找不到保存方法的错误。

公共类DTOname实现了Serializable {
私有整数ID；
私有字符串名称；
public Integer getId（）{
返回ID；
}
公共无效setId（整数ID）{
this.id = id;
}

this is my repository

@RepositoryConfig(cacheName = "mycache")
@Component
@Repository
public interface NewRepo extends IgniteRepository<DTOname, Integer> {

this is my ignite config class
