“放松"；杰克逊(Jackson)的字段名称 [英] "Relaxed" fields names for Jackson

问题描述

我正在研究Jackson配置，我想知道是否有任何选项可以反序列化不同种类的字段模式.

I'm working on Jackson configuration and I wonder if there is any option to deserialise different kinds of field patterns.

例如，我有一个对象:

class DeserializeIt {
    String fieldOne;
    String fieldOneAndHalf;
    String fieldTwo;
    String fieldThree;
    String fieldFour;

   //getters setters etc.
}

我的有效载荷低于JSON:

{
    "fieldOne" : "value1",
    "field_ONE-and_Half": "value15",
    "FIELD_TWO": "value2",
    "FIELD_THREE" : "value3",
    "field_four": "value4"
}

我想将所有这些字段名称反序列化为驼峰式大小写.

I would like to deserialize all these field names to camel case without an exception.

我尝试创建自定义PropertyNamingStrategy，但是它从另一个方向出发:它不会将定界字段转换为驼峰式大小写，而是尝试转换对象字段并在已解析的字符串中搜索它们.

I tried to create my custom PropertyNamingStrategy but it goes from another direction: it does not convert delimitered fields to camel case, it tries to convert the objects fields and search for them in the parsed string.

而且由于我无法传递可能的字符串列表而不是一个变体(fieldOne可以变成field-one，field_one，field-ONE等)，所以这不起作用.

And since I cannot pass a list of possible strings instead of one variation (fieldOne can become field-one, field_one, field-ONE etc.), this does not work.

您知道我还可以为这种轻松的反序列化配置什么吗?

Do you know what else could I configure for such a relaxed deserialization?

推荐答案

对自己有用的方法:我添加了一个AOP组件，该组件将传入对象的所有字段重命名为Camel案例.

What worked for myself: I added an AOP component that renames all the fields of incoming object into the Camel case.
