杰克逊基于场的序列化 [英] Jackson field based serialization

问题描述

我认为Jackson会基于方法进行序列化，有什么方法可以让它基于字段吗？

I think Jackson does method based serialization, is there any way I could make it field based?

Ex：

class Bean {
    Integer i;
    String s;

    public Integer getI() { return this.i; }
    public void setI(Integer i) { this.i = i; }
    public bool isSetI() { return this.i != null; }

    // same for s as well
}

输出JSON具有i和setI。无论如何，我可以覆盖这个只获得我？
如果有一种方法可以在不向类添加任何注释的情况下（它们是自动生成的），也会很棒。

The output JSON has "i" and "setI". Is there anyway I could override this to get only "i"? Also it would be great if there was a way to do this without adding any annotations to the class (they are auto generated).

推荐答案

要在没有注释的情况下完成此操作，您可以在按以下方式序列化/反序列化之前配置 ObjectMapper ：

To accomplish this without annotations you can configure the ObjectMapper before serializing/deserializing in the following manner:

ObjectMapper om = new ObjectMapper();
om.setVisibilityChecker(om.getSerializationConfig().getDefaultVisibilityChecker().
            withGetterVisibility(JsonAutoDetect.Visibility.NONE).
            withSetterVisibility(JsonAutoDetect.Visibility.NONE));
