Spring redis返回500 stackoverflow错误

Question

我正在尝试在 Spring Boot 应用程序中将一些数据保存到 Redis。尝试将数据插入 Redis 时出现 stackoverflow 错误。

我知道这里有一些重复的过程，但真的不明白异常在哪里以及根本原因。

RedisRepo：

public interface RedisRepo extends CrudRepository<RedisEntity,String> {

}

RedisObj：

public class RedisObj {

    @Id
    private Long field1;

    private String field2;

    private String field3;

    private String field4;

    private String field5;

    private UUID field6;

    private String field7;

    private String field8;

    private MyObject field9;

}

来自服务：

redisRepo.save(ObjToRedis);

例外：

任何建议都有帮助。

这里的问题是，我使用的是 hiberante 实体对象（即 Post 中的“MyObject”）。创建了一个新对象，它工作正常。
