Boon - 迄今为止的字符串

ObjectMapper类可用于处理 JSON 中的不同日期格式。它可用于解析/生成日期的字符串版本。

例子

以下示例使用 ObjectMapper 类从 String 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\":\"1998-08-11T11:31:00.034Z\" }";
      
      // mapper converts String 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

当您执行上述代码时，您应该看到以下输出 -

Tue Aug 11 17:01:00 IST 1998
{"name":"Mahesh","age":21,"dateOfBirth":902835060034}
