Boon - 迄今为止很长

ObjectMapper类可用于处理 JSON 中的不同日期格式。它可用于解析/生成长版本的日期。

例子

以下示例使用 ObjectMapper 类从长版本生成日期字符串。

import java.util.Date;
import org.boon.json.JsonFactory;
import org.boon.json.ObjectMapper;

public class BoonTester {
   public static void main(String args[]) {
      ObjectMapper mapper = JsonFactory.create();      
      String jsonString = "{\"name\":\"Mahesh\", \"age\":21, \"dateOfBirth\":976559400000}";
      
      //mapper converts long to date automatically
      Student student = mapper.readValue(jsonString, Student.class);
      System.out.println(student.dateOfBirth);    
      
      //by default mapper converts date to long
      jsonString = mapper.writeValueAsString(student);
      System.out.println(jsonString);    
   }
}
class Student {
   public String name;
   public int age;
   public Date dateOfBirth;
   
   public Student(String name, int age, Date dateOfBirth) {
      this.name = name;
      this.age = age;
      this.dateOfBirth = dateOfBirth;
   }
}

输出
