json無限遞歸與春天roo

我使用Spring Roo 1.2.1和Jackson 1.9.7。在序列化我的QueueOut與JSON我得到一個JsonMappingException。json無限遞歸與春天roo

我閱讀下面的職位，但發現沒有我工作的解決方案：

Jackson - serialization of entities with birectional relationships (avoiding cycles)

我不知道爲什麼JsonIgnore沒有在類隊列工作性質QueueOuts 。我也試過JsonManagedReference，但同樣的錯誤。使用Jackson 2.0.0並不是解決方案，因爲它不受Spring 3.1支持。

有什麼建議嗎？

這裏我堆棧跟蹤的一部分：

這裏我的課：首先

@RooJavaBean 
@RooToString 
public class QueueOut { 

    private String name; 

    private String description; 

    @JsonIgnore 
    @ManyToOne 
    private GenericQueue genericQueue; 


    @ManyToOne (fetch = FetchType.EAGER) 
    private Queue queue; 

}

二

@RooJavaBean 
@RooToString 
@RooJpaActiveRecord 
public class Queue { 

    private String name; 

    private String description; 

    @JsonIgnore 
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "queue", fetch = FetchType.EAGER) 
    private Set<QueueOut> QueueOuts = new HashSet<QueueOut>(); 
}
