com.fasterxml.jackson.databind.deser.UnresolvedForwardReference與@JsonIdentityInfo

Question

我有這樣的錯誤

這是因爲MJ JSON我有這個元素

"employe": 1, 
     "statutControle": { 
      "statutControleID": 1, 
      "description": "vérification documents ok", 
      "controles": [ 
       1234 
      ] 
     } 

這應該是employeID而非僱工

我有這對我的實體，我使用@JsonIdentityInfo：

//bi-directional many-to-one association to Employe 
    @ManyToOne 
    @JoinColumn(name="employeID") 
    private Employe employe; 


    com.fasterxml.jackson.databind.deser.UnresolvedForwardReference:

請添加您的完整的Employe類顯示您嘗試反序列化的所有jackson註釋和json字符串。 這看起來像一個傑克遜bug，因此id不能出現在它們的完整對象之前。
