如何使用jackson序列化java bean并自定义映射键名？

Question

public class Address{
        String city;
        String state;

        //setters and getters
    }   

Address address = new Address();
address.setCity("myCity");
address.setState("myState");

我正在使用以下方法创建地图：

ObjectMapper objectMapper = new ObjectMapper();
Map map = objectMapper.convertValue(address, HashMap.class);

它给出了以下输出：

{"city":"myCity", "state":"myState"}

我需要向键添加类变量名，如下所示：

{"address.city":"myCity", "address.state":"myState"}

如果启用了jackson-annotations：

public class Address{
    @JsonProperty("address.city")
    String city;
    @JsonProperty("address.state")
    String state;

    //setters and getters
}
