Question

我有一个错误

这是因为在mj json我有这个元素

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

这应该是employeID而不是employee

我为我的实体设置了这个，我正在使用@JsonIdentityInfo：

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


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

Answer 1

请添加完整的Employe类，显示您尝试反序列化的所有jackson注释和json字符串。这似乎是一个杰克逊的错误，因此id不能出现在他们的完整对象之前。

使用@JsonIdentityInfo的com.fasterxml.jackson.databind.deser.UnresolvedForwardReference
