我最终实现了以下解决方案。
关系的一端被视为父母。它不需要任何与Jackson相关的注释。
public class Collaboration {
private Set<Tag> tags;
}
关系的另一端实现如下。
public class Tag {
@JsonSerialize(using = SimpleCollaborationSerializer.class)
private Set<Collaboration> collaborations;
}
我正在使用自定义序列化程序来确保不会发生循环引用。序列化器可以这样实现：
public class SimpleCollaborationSerializer extends JsonSerializer<Set<Collaboration>> {
@Override
public void serialize(final Set<Collaboration> collaborations, final JsonGenerator generator,
final SerializerProvider provider) throws IOException, JsonProcessingException {
final Set<SimpleCollaboration> simpleCollaborations = Sets.newHashSet();
for (final Collaboration collaboration : collaborations) {
simpleCollaborations.add(new SimpleCollaboration(collaboration.getId(), collaboration.getName()));
}
generator.writeObject(simpleCollaborations);
}
static class SimpleCollaboration {
private Long id;
private String name;
// constructors, getters/setters
}
}
