项目场景：

提示：Valid校验子类对象中属性：

问题描述

例如：类中包含基本属性与组合子类属性时，子类属性的Valid校验递归@NotBlank、@NotNull不生效。

问题解决方案

如何通过注解方式来实现类属性递归Valid校验？

业务控制层LedgerRest

@RequestMapping("/ledger")
public class LedgerRest {@PostMapping("/workOrderCallback")public Map<String, Object> workOrderCallback(@Valid @RequestBody LedgerCallbackReq ledgerCallbackReq) {return ledgerService.workOrderCallback(ledgerCallbackReq);}}

主类LedgerCallbackReq

import io.swagger.annotations.ApiModelProperty;
import lombok.*;
import javax.validation.Valid;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotEmpty;
import javax.validation.constraints.NotNull;
import java.util.List;/*** @Desc  请求参数Req*/
@Setter
@Getter
@AllArgsConstructor
@NoArgsConstructor
public class LedgerCallbackReq {@ApiModelProperty("绑定关系外键")@NotBlank(message = "foreignKey不能为空或空白")@NotNull(message = "foreignKey不能为空或空白")public String foreignKey;@NotBlank(message = "绑定状态bindingStatus不能为空或空白")@NotNull(message = "绑定状态bindingStatus不能为空或空白")public String bindingStatus;@ApiModelProperty("模板字段列表")@NotEmpty(message = "模板字段列表不能为空")@Validpublic List<LedgerCallbackColumnList> columnList;
}

主类中组合类型的子类 LedgerCallbackColumnList

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import io.swagger.annotations.ApiModelProperty;
import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotEmpty;
import javax.validation.constraints.NotNull;/*** @Description* @Date 2025/4/10 20:56* @Created by chenjun*/
@Setter
@Getter
@AllArgsConstructor
@NoArgsConstructor
public class LedgerCallbackColumnList {@ApiModelProperty("主键")@NotBlank(message = "主键id不能为空或空白")public String id;@ApiModelProperty("模板code")@NotNull(message = "模板code不能为空或空白")@NotBlank(message = "模板code不能为空或空白")public String templateCode; @ApiModelProperty("字段值")@JsonIgnoreProperties({"optionValues"})public String optionValues;
}

主类属性和组合子类与String转化

问题描述：Json串转换成组合类对象时,Json串中部分属性节点可以不存在或者存在不确定性，转换成组合类对象时忽略此属性值。
解决思路：
1.采用fastjson实现String（JSON）转换成组合类对象
2. Json串中存在不确定性的属性节点映射的类属性加入： @JsonIgnoreProperties({“format”})
解决方式：

pom.xml依赖 fastjson

<!-- https://mvnrepository.com/artifact/com.alibaba/fastjson -->
<dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.83</version>
</dependency>

转换类FormItemDto定义

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import lombok.Data;
import java.util.List;
/*** 扩展工单基础表单、台账表单Form组件*/
@Data
public class FormItemDto {//自定义表单字段属性public String title;public String name;public String icon;public String value;public String valueType;public String id;//台账表单字段属性public String ledgerField;public String ledgerValueEn;public String ledgerType;public String ledgerKeyItem;public FormItemPropsDto props;@Datapublic static class FormItemPropsDto {private Boolean required;private Boolean enablePrint;//JSONField忽略属性expanding映射@JsonIgnoreProperties({"expanding"})private Boolean  expanding;//JSONField忽略属性format映射@JsonIgnoreProperties({"format"})private String format;//日期格式，"format": "YYYY-MM-DD HH:mm:ss"@JsonIgnoreProperties({"options"})//JSONField忽略属性options映射private List<String> options;}
}
