org.hibernate.MappingException尽管JPA转换器可用

我有自己的身份证类型

public class Id<T extends AbstractEntity<T>> {}

对于以下数据模型：

@Entity
@Table(name = "CATEGORY")
public class Category extends AbstractEntity<Category> {
   //...
}

public class AbstractEntity<T extends AbstractEntity<T>> implements Entity<T> {

  private static final long serialVersionUID = -2320097975522208226L;

  @javax.persistence.Id
  @GeneratedValue(generator = "id-generator")
  @GenericGenerator(
      name = "id-generator",
      strategy = "com.....IdGenerator",
      parameters = {
        @Parameter(name = "sequence", value = "STANDARD_SEQ")
      })
  @Convert(converter = IdConverter.class, attributeName = "id")
  @Column(columnDefinition = "NUMBER")
  private Id<T> id = Id.newId();
}

@实体
@表（name=“CATEGORY”）
公共类类别扩展了抽象实体{
//...
}
公共类AbstractEntity实现实体{
私有静态最终长serialVersionUID=-232009797552220826L；
@javax.persistence.Id
@GeneratedValue（generator=“id generator”）
@通用生成器(
name=“id生成器”，
strategy=“com…..IdGenerator”，
参数={
@参数（name=“sequence”，value=“STANDARD_SEQ”）
})
@转换（converter=IdConverter.class，attributeName=“id”）
@列（columnDefinition=“NUMBER”）
私有Id=Id.newId（）；
}

我相信，这是因为您的转换器类使用泛型。尝试删除
