Jackson ObjectMapper忽略给定的类

Question

我有这个豆

class Toto
{
    private final String fuu;
    private final String bar;
    Private List<Dog> dogs;
}

class Dog {
 private String name;
 private String race;
}

我想将此bean转换为Map＆lt;＆gt;使用：

ObjectMapper serializer = new ObjectMapper();
serializer.setSerializationInclusion(JsonInclude.Include.NON_NULL);
return serializer.convertValue(entry, Map.class);

此代码结果是Dog对象也被转换为Map。

我想要一个解决方案，以便在最终地图中我会：

fuu=fuu_value_as_String
bar=bar_value_as_String
dogs=[ObjectDog1, ObjectDog2] // i do not want the Object to be  
converted (because i have an instanceof check later in the code)
