Boon - String To Date

ObjectMapper 类可以用于处理 JSON 中不同的日期格式。它可以用来解析/生成字符串版本的日期。

Example

以下示例使用 ObjectMapper 类从字符串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;
   }
}

Output

执行以上代码时,应该看到以下输出 −

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