如何在annotation @CreatedDate中设置默认日期？

import org.springframework.data.annotation.CreatedDate;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import java.util.Date;

@Entity
public class YourEntity {
    @Id
    @GeneratedValue
    private Long id;

    @CreatedDate
    private Date createdDate;

    // 其他字段和方法
}

import org.springframework.data.auditing.DateTimeProvider;

import java.util.Calendar;
import java.util.Date;

public class CustomDateTimeProvider implements DateTimeProvider {
    @Override
    public Calendar getNow() {
        Calendar calendar = Calendar.getInstance();
        calendar.set(2022, Calendar.JANUARY, 1); // 设置默认日期为2022年1月1日
        return calendar;
    }
}

import org.springframework.context.annotation.Configuration;
import org.springframework.data.jpa.repository.config.EnableJpaAuditing;

@Configuration
@EnableJpaAuditing(dateTimeProviderRef = "customDateTimeProvider")
public class JpaConfig {
    // 其他配置
}
