RESTful Java服務不序列化ArrayList

Question

以下是我的GET方法的示例代碼，該方法應返回xml序列化版本的ConfigurationProperty作爲響應。

它在大多數時間序列化ConfigurationProperty模型，除非value設置爲ArrayList。

什麼可能是原因，當我使用javax.ws.rs.Produces完成序列化時，應如何修復它？的cp

@GET 
@Path("{id}") 
@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML }) 
public ConfigurationProperty getConfigurationProperty(@PathParam("id") Id id) 
{ 
    ConfigurationProperty cp = service.get(ConfigurationProperty.class, id); 
    return checked(cp); 
} 

內容：

cp DefaultConfigurationProperty (id=293) 
    __scsIsPartialObject false 
    __scsTransientServiceFields HashMap<K,V> (id=312) 
    createdBy "migration" (id=313)  
    createdOn Date (id=314) 
    id Id (id=315)  
    key "catalog/cron/product_status_export/try_languages" (id=316) 
    merchantIds null  
    modifiedBy null  
    modifiedOn null  
    requestContextIds null  
    storeIds null  
    value ArrayList<E> (id=317)

這聽起來像你可能需要添加自定義序列爲DefaultConfigurationProperty的價值領域。你應該可以用Jackson自定義序列化器[1]完成這個任務。
