如何指定jackson只使用字段 - 最好全局 [英] how to specify jackson to only use fields - preferably globally

问题描述

默认的jackon行为似乎使用两个属性（getter和setter）和字段来序列化和反序列化为json。

Default jackon behaviour seems to use both properties (getters and setters) and fields to serialize and deserialize to json.

我想使用这些字段作为规范序列化配置源，因此根本不希望jackson查看属性。

I would like to use the fields as the canonical source of serialization config and thus don't want jackson to look at properties at all.

我可以使用注释在单个类的基础上执行此操作：

I can do this on an individual class basis with the annotation:

 @JsonAutoDetect(fieldVisibility = Visibility.ANY, getterVisibility = Visibility.NONE, setterVisibility = Visibility.NONE)

但我不想把它放在每一个班级......

But I don't want to have to put this on every single class...

是否可以全局配置？就像在Object Mapper中添加一些一样？

Is it possible to configure this globally? Like add some to the Object Mapper?

推荐答案

您可以像这样配置各个ObjectMappers：

You can configure individual ObjectMappers like this:

ObjectMapper mapper  = new ObjectMapper();
mapper.setVisibilityChecker(mapper.getSerializationConfig().getDefaultVisibilityChecker()
                .withFieldVisibility(JsonAutoDetect.Visibility.ANY)
                .withGetterVisibility(JsonAutoDetect.Visibility.NONE)
                .withSetterVisibility(JsonAutoDetect.Visibility.NONE)
                .withCreatorVisibility(JsonAutoDetect.Visibility.NONE));

如果要全局设置，我通常会通过包装器类访问已配置的映射器。

If you want it set globally, I usually access a configured mapper through a wrapper class.
