将Json字段包装到pojo的实例变量中

@JsonUnwrapped

class Person {    private String name;    @JsonUnwrapped    private Address address;    // getters, setters, toString}class Address {    private String street;    private String city;    // getters, setters, toString}

用法：

ObjectMapper mapper = new ObjectMapper();String json = "{"name":"Alexander","street":"abc 12","city":"London"}";System.out.println(mapper.readValue(json, Person.class));

印刷品：

Person{name='Alexander', address=Address{street='abc 12', city='London'}}
