JSON parse error: Already had POJO for id
JSON parse error: Already had POJO for id
我已经看到了一些关于这个主题的问题，但我无法将其应用到我的案例中，因为我尝试应用它们，但错误仍然存在。
所以我来揭露我的情况。
我读了一些关于它的评论，并说如果我在 class Entidade 中更改我的列 idEntidade 的名称，我就可以成功。但是我不能改变数据库。
我试图将 scope= Distritos.class 放入我的 @JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "idDistrito") 但它没有用。
我需要帮助。
我正在尝试使用 spring MVC 和 Angular 将数据保存在我的数据库中。当我点击保存数据时，我得到了这个错误

有两个问题：
1。身份范围
两个 @JsonIdentityInfo 都应该在范围内，因为您的两个 class 都具有相同的生成器类型 - ObjectIdGenerators.PropertyGenerator.class.
Scope is used to define applicability of an Object Id: all ids must be
unique within their scope; where scope is defined as combination of
this value and generator type. Comparison is simple equivalence,
meaning that both type generator type and scope class must be the
same. Scope is used for determining how many generators are needed;
more than one scope is typically only needed if external Object Ids
have overlapping value domains (i.e. are only unique within some
limited scope)
对于Distritos：
@JsonIdentityInfo(scope = Distritos.class, generator = ObjectIdGenerators.PropertyGenerator.class, property = "idDistrito")
Entidades：
@JsonIdentityInfo(scope = Entidades.class, generator = ObjectIdGenerators.PropertyGenerator.class, property = "idEntidade")
2。字段命名
@JoinColumn()
@ManyToOne
private Entidades idEntidade;
以某种方式干扰
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
private Long idEntidade;
当您向 Jackson 反序列化器传递一个完整的 Distritos 对象时（包含 Entidades 内部，如您的示例所示）。
我做了一些调试，发现 BeanDeserializer（按名称解析字段）无法反序列化 属性 字段，因为它与 id 字段同名，所以我更改了 idEntidade 到 entidade 在 Distritos class.
进行这些更改后，我的示例项目工作正常（因为我已经从您的 classes - Distritos.idMunicipio、Distritos.idUf 和所有 Collections 中删除了一些字段来自 Entidades)。你必须检查其他classes（例如Municipios和Ufs）是否有相同的问题，并修复它们。
我已经看到了一些关于这个主题的问题，但我无法将其应用到我的案例中，因为我尝试应用它们，但错误仍然存在。 所以我来揭露我的情况。
我读了一些关于它的评论，并说如果我在 class Entidade 中更改我的列 idEntidade 的名称，我就可以成功。但是我不能改变数据库。
