Jackson注释 - @JsonUnwrapped
@JsonUnwrapped用于在序列化或反序列化期间解开对象的值。
示例 - @JsonUnwrapped
import java.io.IOException; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Date; import com.fasterxml.jackson.annotation.JsonUnwrapped; import com.fasterxml.jackson.databind.ObjectMapper; public class JacksonTester { public static void main(String args[]) throws IOException, ParseException{ ObjectMapper mapper = new ObjectMapper(); SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd-MM-yyyy"); Date date = simpleDateFormat.parse("20-12-1984"); Student.Name name = new Student.Name(); name.first = "Jane"; name.last = "Doe"; Student student = new Student(1, name); String jsonString = mapper .writerWithDefaultPrettyPrinter() .writeValueAsString(student); System.out.println(jsonString); } } class Student { public int id; @JsonUnwrapped public Name name; Student(int id, Name name){ this.id = id; this.name = name; } static class Name { public String first; public String last; } }
输出
{ "id" : 1, "first" : "Jane", "last" : "Doe" }
