ジャクソン注釈-@JsonAutoDetect

*@ JsonAutoDetect* を使用して、他の方法ではアクセスできないプロパティを含めることができます。

例-@JsonAutoDetect

import java.io.IOException;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.databind.ObjectMapper;

public class JacksonTester {
   public static void main(String args[]){
      ObjectMapper mapper = new ObjectMapper();
      try{
         Student student = new Student(1,"Mark");
         String jsonString = mapper
            .writerWithDefaultPrettyPrinter()
            .writeValueAsString(student);
         System.out.println(jsonString);
      }
      catch (IOException e) {
         e.printStackTrace();
      }
   }
}
@JsonAutoDetect(fieldVisibility = JsonAutoDetect.Visibility.ANY)
class Student {
   private int id;
   private String name;

   Student(int id,String name) {
      this.id = id;
      this.name = name;
   }
}

出力

{
   "id" : 1,
   "name" : "Mark"
}
