杰克逊嵌入式Java对象的反序列化

我必须反序列化以下json使用杰克逊图书馆进入客户类

{
   "code":"C001","city": "Pune","street": "ABC Road"
}

和类作为

class Address{
    String city;
    String street;
}

class Customer{
    String code;
    Address address;
}

我已经在堆栈上找到了类似的问题
Java jackson embedded object deserialization

但答案不适用于我的情况.另外我只想使用杰克逊图书馆.

如何将此json映射到Customer对象？

解决方法

public class JacksonValue {
    final static String JSON = "{n"
            +"   "code":"C001",n"
            +"   "city": "Pune",n"
            +"   "street": "ABC Road"n"
            +"}";

    static class Address {
        public String city;
        public String street;

        @Override
        public String toString() {
            return "Address{" +
                    "city='" + city + ''' +
                    ",street='" + street + ''' +
                    '}';
        }
    }

    static class Customer {
        public String code;
        @JsonUnwrapped
        public Address address;

        @Override
        public String toString() {
            return "Customer{" +
                    "code='" + code + ''' +
                    ",address=" + address +
                    '}';
        }
    }


    public static void main(String[] args) throws IOException {
        final ObjectMapper mapper = new ObjectMapper();
        System.out.println(mapper.readValue(JSON,Customer.class));
    }
}

输出：

Customer{code='C001',address=Address{city='Pune',street='ABC Road'}}
