使用Jackson数据绑定跳过嵌套字段？(Skipping nested field with Jackson data binding?)

 我如何使用Jackson将以下json片段绑定（双向）到下面的Java对象？ 
 
 我希望Json新闻稿节点的键/值对最终位于新闻稿字段的Map中。 什么必须是杰克逊配置（注释和其他）绑定这个？ 对不起，我不知道如何:(（使用最新版本的杰克逊）。 
 
 下面的Json格式是固定的，我从第三方休息服务（我无法更改）接收它。 我可以更改java代码，但更喜欢下面的设置。 
 
 JSON： 
 
{
    "newsletter": {
        "key1": "value1",
        "key2": "value2",
        "key3": "value3"
    }
}
 
 Java对象： 
 
class Preferences {
    private NewsLetter newsLetter;
    // getter/setter for field newsLetter.
}

class NewsLettter {
    private Map<String, String> properties;
    // getter/setter for field properties.
}

How must I bind (bidirectional) the following json snippet to the Java objects below with Jackson?
 
I want the key/value pairs of the Json newsletter node to end up in the Map of the newsletter field. What must be the Jackson config (annotations and others) to bind this ? Sorry, I don't know how :( (using the latest version of Jackson).
 
The Json format below is fixed, I receive it from a third party rest service (I can't change it). I can change the java code, but prefer the setup below.
 
JSON:
 
{
    "newsletter": {
        "key1": "value1",
        "key2": "value2",
        "key3": "value3"
    }
}
 
The Java Objects:
 
class Preferences {
    private NewsLetter newsLetter;
    // getter/setter for field newsLetter.
}

class NewsLettter {
    private Map<String, String> properties;
    // getter/setter for field properties.
}
