Jakarta EE 10 序列化人员实体导致递归检查器异常（来自 org.eclipse.yasson.internal.serializer.RecursionChecker）

Question

我正在尝试使用简单的 Web 服务将

Person

实体序列化为 JSON，但出现以下异常：

一些递归检查器正在抱怨。这曾经使用 Java EE 8 工作。

我只是想显示具有球员、教练或裁判员角色的人员列表。一个人可以扮演所有这三种角色，三种角色的任意组合，或者根本没有。

联系方式抽象/超实体；

@Entity
@Table(name = "\"Contacts\"")
@Inheritance(strategy = InheritanceType.JOINED)
@DiscriminatorColumn(name = "type", discriminatorType = DiscriminatorType.STRING)
@XmlRootElement
public abstract class Contact implements Serializable
{
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column
    protected Integer id;

    @Basic(optional = false)
    @Column(insertable = false, updatable = false)
    @Convert(converter = ContactTypeConverter.class)
    protected ContactType type;

    ...
}

人实体；

@Entity
@Table(name = "\"Persons\"")
@DiscriminatorValue("P")
@NamedQuery(name = Person.FIND_ALL, query = "SELECT pe FROM Person pe ORDER BY pe.lastName, pe.firstName")
@NamedEntityGraph(name = Person.FETCH_EMAIL_ADDRESSES_PHONE_NUMBERS_AND_ROLES,
    attributeNodes = {
        @NamedAttributeNode(value = "player"),
        @NamedAttributeNode(value = "coach"),
        @NamedAttributeNode(value = "referee")}
)
public class Person extends Contact
{
    private static final long serialVersionUID = 1L;

    public static final String FIND_ALL = "Person.findAll";
    public static final String FETCH_ROLES = "Person.fetchRoles";

    @Basic(optional = false)
    @Column(name = "first_name")
    private String firstName;

    @Basic(optional = false)
    @Column(name = "last_name")
    private String lastName;

    @Basic(optional = false)
    @Column
    @Enumerated(EnumType.STRING)
    private PersonGender gender = PersonGender.MALE;

    @Basic
    @Column(name = "birth_date")
    private LocalDate birthDate;

    @Basic(optional = false)
    @Column(name = "is_incognito")
    private Boolean incognito = Boolean.FALSE;

    @OneToOne(mappedBy = "person", fetch = FetchType.LAZY)
    private Coach coach;

    @OneToOne(mappedBy = "person", fetch = FetchType.LAZY)
    private Player player;

    @OneToOne(mappedBy = "person", fetch = FetchType.LAZY)
    private Referee referee;
    
    ...
}

玩家实体（可能的角色#1）；

@Entity
@Table(name = "\"Players\"")
@XmlRootElement
public class Player implements Serializable
{
    private static final long serialVersionUID = 1L;

    @Id
    @Column
    private Integer id;

    @Basic
    @Column(name = "registration_nbr")
    private String registrationNbr;

    @OneToOne(optional = false, fetch = FetchType.EAGER)
    @JoinColumn(name = "id", insertable = false, updatable = false)
    @XmlTransient
    private Person person;
    
    ...
}

教练实体（可能的角色#2）；

@Entity
@Table(name = "\"Coaches\"")
@XmlRootElement
public class Coach implements Serializable
{
    private static final long serialVersionUID = 1L;

    @Id
    @Column
    private Integer id;

    @Basic
    @Column(name = "license_nbr")
    private String licenseNbr;

    @OneToOne(optional = false, fetch = FetchType.EAGER)
    @JoinColumn(name = "id", insertable = false, updatable = false)
    @XmlTransient
    private Person person;
    
    ...
}

裁判员实体（可能的角色#3）；

@Entity
@Table(name = "\"Referees\"")
@XmlRootElement
public class Referee implements Serializable
{
    private static final long serialVersionUID = 1L;

    @Id
    @Column
    private Integer id;

    @Basic
    @Column(name = "license_nbr")
    private String licenseNbr;

    @OneToOne(optional = false, fetch = FetchType.EAGER)
    @JoinColumn(name = "id", insertable = false, updatable = false)
    @XmlTransient
    private Person person;
    
    ...
}

如您所见，我无法对

Player

、

Referee

和

Coach

使用继承。 JPA 被指定为仅支持完全继承。所以基本上，每个角色都有一个简单的

@OneToOne

映射。

请注意，

@DiscriminatorValue("P")

实体上有

Person

，因为有个人、俱乐部和竞技场，通常可以联系到它们，并且通过真正的

Contact

从

@Inheritance(strategy = InheritanceType.JOINED)

派生（参见上面的实体）。我在示例中省略了这些。

PersonWebService：

@Path("/person")
public class PersonWebService {
    @Inject
    private PersonService personService;

    @GET
    @Path("/findall")
    @Produces(MediaType.APPLICATION_JSON)
    public List<Person> getPersonList() {
        List<Person> persons = personService.findAllWithFetchGraph(Person.FETCH_ROLES); // <-- EXCEPTION!

        return persons;
    }

    @GET
    @Path("/find/{id}")
    @Produces(MediaType.APPLICATION_JSON)
    public Person getPerson(@PathParam("id") Integer id) {
        Person person = personService.findByPk(id);

        return person;
    }
}

又出现错误：

RESTEASY008205: JSON Binding serialization error jakarta.json.bind.JsonbException: Unable to serialize property 'player' from net.bbstats.entity.Person

问题：

这里出了什么问题？

既然

Player.person

被声明为

@XmlTransient private Person person;

，为什么会抛出异常？顺便说一句，所有角色实体都会发生这种情况。我希望所有人都将这三个角色序列化为 JSON 以便进一步处理。

我的设置是使用 WildFly 31.0.0.Final 的 Jakarta EE 10。基本上所有正在使用的（类加载的）都来自那里，按原样。我没有关于 webservices/JSON 的特殊 webapp 库。

RESTeasy 好像是 6.0.0.Beta1。

Answer 1

WildFly 31 和 RESTEasy 使用 Jakarta JSON Binding 作为默认的 JSON 对象序列化器。 XML 绑定注释在那里不起作用。您需要更改注释以使用 Jakarta JSON Binding 注释，或者切换到使用 Jackson 作为 JSON 序列化器 2。

如果您想默认使用 Jackson 进行所有部署，您可以更改

resteasy-prefer-jackson-over-jsonb

。使用 CLI，命令将是：

/subsystem=jaxrs:write-attribute(name=resteasy-prefer-jackson-over-jsonb, value=true)

FWIW WildFly 31 的 RESTEasy 版本是 6.2.7.Final。
