springboot @Validated分组功能用在service层校验对象解决方案

逃离我推掉我的手 2022-12-07 01:17 376阅读 0赞

最近做一个项目，用的springboot2.2.0.RELEASE+mybatisplus3.2.0架构，想着springboot这么强大了，里面有的功能都得用上秀一把技，结果翻车了。

在参数校验这块使用了spring-boot-starter-validation注解校验参数，可避免业务代码中无休止的参数校验判断，但在分层的方面来说，参数校验一般都是在Controller层完成的，但这一次情况特殊：提供的是dubbo服务。

话不多说，直接上代码

ValidGroup代码

public class ValidGroup {     public interface Insert extends Default {    }     public interface Update extends Default {    }  }

model代码

@Data@Builder@NoArgsConstructor@AllArgsConstructor@TableName("brand")public class Brand extends BaseModel {     @TableId(value = "id", type = IdType.AUTO)    @NotNull(message = "{Brand.id.null}", groups = {ValidGroup.Update.class})    private Long id;     @NotBlank(message = "{Brand.brandCode.null}")    @Size(min = 5, max = 5, message = "{Brand.brandCode.size}", groups = {ValidGroup.Insert.class, ValidGroup.Update.class})    @TableField    private String brandCode;     @NotBlank(message = "{Brand.brandName.null}")    @Size(min = 1, max = 50, message = "{Brand.brandName.size}", groups = {ValidGroup.Insert.class, ValidGroup.Update.class})    private String brandName;     @NotBlank(message = "{Brand.brandEnName.null}")    @Size(min = 1, max = 50, message = "{Brand.brandEnName.size}", groups = {ValidGroup.Insert.class, ValidGroup.Update.class})    private String brandEnName;     @NotBlank(message = "{Brand.brandType.null}")    @Size(min = 1, max = 50, message = "{Brand.brandType.size}", groups = {ValidGroup.Insert.class, ValidGroup.Update.class})    private String brandType;     @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")    @JSONField(format = "yyyy-MM-dd HH:mm:ss")    private Date updateTime; }

service层代码

V1初始没分组时代码

@Validated@Servicepublic class BrandServiceImpl extends ServiceImpl<BrandMapper, Brand> implements BrandService {     @Override    public Brand getBrandByCode(String brandCode) {        return getById(brandCode);    }     @Override    public boolean saveBrand(@Valid Brand brand) {        return save(brand);    }     @Override    public boolean updateBrand(@Valid Brand brand) {        return updateById(brand);    }  }

V2有分组时代码

@Validated@Servicepublic class BrandServiceImpl extends ServiceImpl<BrandMapper, Brand> implements BrandService {     @Override    public Brand getBrandByCode(String brandCode) {        return getById(brandCode);    }     @Override    public boolean saveBrand(@Validated({ValidGroup.Insert.class}) Brand brand) {        return save(brand);    }     @Override    public boolean updateBrand(@Validated({ValidGroup.Update.class}) Brand brand) {        return updateById(brand);    }  }

V1版本是可以校验住的，只是在修改的方法里有些字段要排除掉,为了解决差异引入了分组,V2版本添加了分组后就直接提交给测试了。

过了没多久，来了一个bug，说创建和修改都失效了。。。

检查写法，百度，发现基本都是这样的写法

。。。。

检查了MethodValidationPostProcessor和MethodValidationInterceptor，一步步debug，没找到原因。。。

因有排期，所以就先用了if else搞定了校验。

正好今天他有空，之前排查打开的网页还没关，正好接着排查。

才发现写法有问题

后来换了写法搞定了

@Validated@Servicepublic class BrandServiceImpl extends ServiceImpl<BrandMapper, Brand> implements BrandService {     @Override    public Brand getBrandByCode(@NotBlank String brandCode) {        return getById(brandCode);    }     @Override    @Validated({ValidGroup.Insert.class})    public boolean saveBrand(@Valid Brand brand) {        return save(brand);    }     @Override    @Validated({ValidGroup.Update.class})    public boolean updateBrand(@Valid Brand brand) {        return updateById(brand);    } }
