Quarkus、PanacheEntity 和保存列表或集合
Quarkus, PanacheEntity and saving lists or sets
我正在尝试保留包含关联实体的实体：
@Entity
public class Indicator extends PanacheEntity {
@Id @GeneratedValue private Long id;
public String name;
@OneToMany(mappedBy="id", cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.EAGER)
public List<IndicatorInput> inputs;
@OneToMany(mappedBy="id", cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.EAGER)
public Set<IndicatorOutput> outputs;
}
集合是：
@Entity
public class IndicatorInput extends AbstractIndicatorValue {
@Id @GeneratedValue private Long id;
}
和
@Entity
public class IndicatorOutput extends AbstractIndicatorValue {
@Id @GeneratedValue private Long id;
public String color;
public String style;
}
当我尝试通过 REST 保留 Indicator 实例时，它失败并出现以下错误：

- 将
quarkus-resteasy-jsonb更改为resteasy-jackson
- 使用
List 更改为 Set
- 已尝试用
@Inheritance 注释摘要 class
- 已尝试用
@MappedSuperclass 注释摘要 class
- public 每个实体的无参数构造函数

- 二手
cascade = CascadeType.PERSIST
这里有几个问题的组合。
PanacheEntity 本身包含 id 字段。因此，您需要从 Indicator 或 中删除 id 字段，使 Indicator 扩展 PanacheEntityBase.- 你的
id 是私有的，这只会带来反序列化的问题（尤其是 PanacheEntity 已经有 id 字段）。因此，使其成为 public 或创建 getter 和 setter。
- 我还向
@GeneratedValue 添加了策略作为身份以使其可递增
下面是一个适合我的工作实现。没有 AbstractIndicatorValue 的例子，所以我假设它是 class 扩展 PanacheEntity.
- IndicatorInput.java
@Entity
// Make AbstractIndicatorValue extend PanacheEntityBase
public class IndicatorInput extends PanacheEntityBase {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
public Long id;
}
- IndicatorOutput.java
@Entity
// Make AbstractIndicatorValue extend PanacheEntityBase
public class IndicatorOutput extends PanacheEntityBase {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
public Long id;
public String color;
public String style;
}
- Indicator.java
@Entity
public class Indicator extends PanacheEntityBase {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
public Long id;
public String name;
@OneToMany(mappedBy = "id", cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.EAGER)
public List<IndicatorInput> inputs;
@OneToMany(mappedBy = "id", cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.EAGER)
