如何停止@JsonProperty导致使用父类序列化程序？

Question

我正在将jackson-databind从版本2.9.0升级到2.9.8，并且遇到一个问题，其中@JsonProperty值导致spring将来自父方法的@JsonSerialize值映射到相同的名字。

子类的示例：

public class SubClassEntity extends AbstractEntity {

    @JsonView(SubClassEntity.class)
    @JsonProperty("user")
    @JsonSerialize(using = UserSubClassEntitySerialzer.class)
    public Entity getSubClassUser() {
        return super.getEntity();
    }

    @JsonView(SubClassEntity.class)
    @JsonProperty("userAlternative")
    public UserEntity getSubClassUserAlternative() {
        final User user = super.getUserAlternative();
        return null != user ? new UserEntity(user) : null;
    }
}

父类的示例

public class AbstractEntity {

        protected final Entity entity;

    public AbstractEntity (final Entity entity) {
        this.entity = entity;
    }

    public Entity getEntity() {
        return this.entity;
    }

    @JsonView(Object.class)
    @JsonSerialize(using = UserInfoSerializer.class)
    public User getUser() {
        return this.entity.getUser();
    }

    @JsonView(Object.class)
    @JsonSerialize(using = UserInfoSerializer.class)
    public User getUserAlternative() {
        return this.entity.getUserAlternative();
    }
}

UserSubClassEntitySerialzer

public class UserSubClassEntitySerialzer extends JsonSerializer<Entity> {

does stuff

}

UserInfoSerializer

public class UserInfoSerializer extends JsonSerializer<User> {

does stuff

}

当我们尝试序列化子类时，无论是否在子类中设置了一个名称，都会使用在JsonProperty中找到的名称的父类上设置的JsonSerializer。这会导致ClassCastException：

com.fasterxml.jackson.databind.JsonMappingException: package.UserEntity cannot be cast to package.User(through reference chain: package.SubClassEntity["userAlternative"])

和

com.fasterxml.jackson.databind.JsonMappingException: package.Entity cannot be cast to package.User(through reference chain: package.SubClassEntity["user"])

    at com.fasterxml.jackson.databind.ObjectWriter.writeValueAsString(ObjectWriter.java:993)

在确定序列化程序时，子类是否可以忽略JsonProperty值？
