java - 如何在springboot注释中的这3个字段类型Date之间进行约束验证？

Question

SPRINGBOOT 和 THYMELEAF 验证

我正在尝试在这 3 个字段类型 Date 之间进行字段验证，但我不知道如何进行！

这些是上下文：

• 如果 folderDate2 不为 null，则 folderDate1 应小于或等于 folderDate2
• 如果 folderDate3 不为 null，则 folderDate2 应小于或等于 folderDate3
• folderDate3 应该高于或等于 folderDate2 并且（folderDate1 和 folderDate2 不应为空）

package io.bmsi.entity.staff;

import java.util.Date;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.validation.constraints.NotBlank;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;

@Entity
@Data @NoArgsConstructor @AllArgsConstructor @ToString
public class Folder {

@Id @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long folderId;
    @NotBlank(message = "fill folder name!!")
    private String folderName;
    
//SPRINGBOOT VALIDATION FOR THESE 3 FIELDS TYPE DATE 
    @NotNull
    private Date folderDate1; // folderDate1 should be lower or equal folderDate2 if folderDate2 is not null
    private Date folderDate2; // folderDate2 should be lower or equal folderDate3 if folderDate3 is not null
    private Date folderDate3; // folderDate3 should be higher or equal folderDate2 and (folderDate1 and folderDate2 should not null) 
}
