Java Jackson注释未与Spring boot一起使用

我正在使用Spring boot 1.0.1.RELEASE，并试图让它获取一些Jackson注释。更具体地说，我尝试使用

@JsonManagedReference

和

@JsonBackReference

注释。你知道为什么这会被忽略吗？我也尝试了

@JsonIgnore

，但似乎也没有被接受

我已经尝试了上面提到的两件事（将Jackson注释移到第一位，并使用

列表

而不是

集合

）。我也看了，但那也帮不了我

更新：

这是我的

组件类型

类：

@Entity
public class ComponentType
{
// ------------------------------ FIELDS ------------------------------

    @Id
    @GeneratedValue()
    private long m_id;

    private String m_name;

    @JsonManagedReference
    @OneToMany(cascade = CascadeType.ALL)
    @JoinColumn(name = "parent_id")
    private List<ComponentSubtype> m_subtypes;

// --------------------------- CONSTRUCTORS ---------------------------

    public ComponentType()
    {
    }

    public ComponentType( String name, Iterable<ComponentSubtype> subtypes )
    {
        m_name = name;
        m_subtypes = Lists.newArrayList(subtypes);
    }

    // -------------------------- PUBLIC METHODS --------------------------

    public long getId()
    {
        return m_id;
    }

    public void setId( long id )
    {
        m_id = id;
    }

    public String getName()
    {
        return m_name;
    }

    public void setName( String name )
    {
        m_name = name;
    }

    public List<ComponentSubtype> getSubtypes()
    {
        return m_subtypes;
    }

    public void setSubtypes( List<ComponentSubtype> subtypes )
    {
        m_subtypes = subtypes;
    }

    public ComponentSubtype getSubtype( final long subtypeId )
    {
        return Iterables.find( getSubtypes(), new Predicate<ComponentSubtype>()
        {
            @Override
            public boolean apply( ComponentSubtype input )
            {
                return input.getId() == subtypeId;
            }
        } );
    }

控制员：

@RestController
@RequestMapping("/api/components")
public class ComponentTypeController
{
    @Autowired
    private ComponentTypeRepository m_repository;

    @RequestMapping("/list")
    public Iterable<ComponentType> listComponents()
    {
        return m_repository.findAll();
    }
}

如果我将浏览器指向

http://localhost:8080/api/components/list

，然后我得到一个stackoverflow异常

这是我得到的stacktrace的一部分：

演示问题的示例项目：

从

下载这是您的（老式的IMO）字段命名约定（“m_*”）。

---

杰克逊并没有把他们和二传手联系起来。因此，您必须要么

@JsonIgnore

getter和setter，要么更改命名，要么注释getter。或者，

@JsonBackReference（…）

中可能有一个功能<例如，code>@JsonBackReference（“componentType”）可能有用。

您使用的是什么版本的Jackson？确保它是Spring Boot支持的（例如，通过使用starter POM作为依赖项-Jackson包含在web starter中）。我正在使用

Spring Boot starter web

依赖项，这似乎给了我Jackson 2.3.2OK，那么它应该可以工作。你想更准确地做什么？也许在问题中添加一些代码？我已经添加了代码。谢谢你看。有什么方法可以让Jackson进行更多的调试吗？谢谢，这很有帮助。那么，从端点得到了什么呢？如果是JSON，我想Jackson可以工作，但您的字段级注释不能工作？也许你也可以把异常的一小段循环放在问题中？我最终将注释从字段移动到getter来修复它。

public interface ComponentTypeRepository extends CrudRepository<ComponentType, Long>
{
}

    ConfigurableApplicationContext context = SpringApplication.run( Main.class, args );
ComponentTypeRepository componentTypeRepository = context.getBean( ComponentTypeRepository.class );
componentTypeRepository.save( new ComponentType( "Component A", Sets.newHashSet( new ComponentSubtype( "Sub A - 1" ), new ComponentSubtype( "Sub A - 2" ) ) ) );
componentTypeRepository.save( new ComponentType( "Component B", Sets.newHashSet( new ComponentSubtype( "Sub B - 1" ), new ComponentSubtype( "Sub B - 2" ) ) ) );
componentTypeRepository.save( new ComponentType( "Component C", Sets.newHashSet( new ComponentSubtype( "Sub C - 1" ), new ComponentSubtype( "Sub C - 2" ) ) ) );
