spring@Validated校验用法

1、controller添加注解

public BaseResponse addOrUpdateUnit(@RequestBody @Validated RiskUnitDto riskUnitDto) {
        doublePreventDataService.addOrUpdateUnit(riskUnitDto);
        return BaseResponse.success(null);
    }

2、参数对象添加注解

package com.cosmo.hg.synctask.dto;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import lombok.experimental.Delegate;
import org.hibernate.validator.constraints.Range;

import javax.validation.Valid;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
import java.math.BigDecimal;
import java.util.List;

@Data

    @ApiModelProperty(value = "标识",required = true)
    @NotBlank(message = "sign不能为空")
    private String sign;

    @Valid
    @ApiModelProperty(value = "风险分析单元对象数据",required = true)
    private List<RiskUnitData> data;

    @Data
    public static class RiskUnitData{

        @NotBlank(message = "riskUnitLocation:分析单元位置不能为空")
        @ApiModelProperty(value = "分析单元位置",required = true)
        @Size(max = 100,message = "riskUnitLocation:分析单元位置不能大于100个字符")
        private String riskUnitLocation;

        @ApiModelProperty(value = "风险等级")
        @Range(max = 3,min = 0,message = "riskLevel:风险等级传值不对")
        @NotBlank(message = "riskLevel:风险等级不能为空")
        private String  riskLevel;

        @ApiModelProperty(value = "联系电话")
        private String  contactNumber;

//        @ApiModelProperty(value = "责任人")
//        private String  hazardLiablePerson;
        @NotBlank(message = "责任人名称不能为空")
        @ApiModelProperty(value = "责任人名称",required = true)
        @Size(max = 50,message = "责任人名称不能大于50个字符")
        private String  hazardLiablePersonName;

        @NotBlank(message = "风险分析对象名称不能为空")
        @ApiModelProperty(value = "风险分析对象名称",required = true)
        @Size(max = 50,message = "风险分析对象名称不能大于50个字符")
        private String  riskObjectName;
        @NotBlank(message = "分析单元编码不能为空")
        @ApiModelProperty(value = "分析单元编码",required = true)
        @Size(max = 50,message = "分析单元编码不能大于50个字符")
        private String riskUnitCode;


        @NotBlank(message = "是否具有中毒、爆炸、火灾等危险的场所 0-否1-是不能为空")
        @ApiModelProperty(value = "是否具有中毒、爆炸、火灾等危险的场所 0-否1-是")
        @Range(max = 1,min = 0,message = "是否具有中毒、爆炸、火灾等危险的场所 0-否1")
        private String dangerousPlace;

        @NotBlank(message = "设备设施编号不能为空")
        @ApiModelProperty(value = "设备设施编号",required = true)
        @Size(max = 50,message = "equipmentId：设备设施编号不能大于50个字符")
        private String equipmentId;

        @NotBlank(message = "作业活动编号不能为空")
        @ApiModelProperty(value = "作业活动编号",required = true)
        @Size(max = 50,message = "activityworkId：作业活动编号不能大于50个字符")
        private String activityworkId;

        @NotBlank(message = "riskpointType:风险点类型不能为空")
        @ApiModelProperty(value = "风险点类型",required = true)
        @Range(max = 3,min = 1,message = "riskpointType：风险点类型传值不对")
        private String riskpointType;
    }



}

说明：

@NotBlank 校验字符串，并且校验字符串是否为空""

@NotNull 校验是否为空null，包装类型

@Size字符串长度校验

@Range数字范围校验  @Range(max = 3,min = 0)
