springboot整合 validator

第一步：spring-boot-validate

<dependencies>

</dependencies>

第二步：创建application.yml文件

第三步： 配置类

第四步： validate 分组

1. AddGroup

public interface AddGroup {
}

2. EditGroup

/**
 * 校验分组 edit
 */
public interface EditGroup {
}

3. QueryGroup

/**
 * 校验分组 query
 */
public interface QueryGroup {
}

第五步：创建ValidatorUtils

@NoArgsConstructor(access = AccessLevel.PRIVATE)
public class ValidatorUtils {
    private static final Validator VALID = SpringUtil.getBean(Validator.class);

    public static <T> void validate(T object,Class<?>... groups) {
        Set<ConstraintViolation<T>> validate = VALID.validate(object,groups);

        if (!validate.isEmpty()){
            throw new ConstraintViolationException("参数校验异常", validate);
        }
    }
}

第六步：创建测试

1. bo类

@Data
public class TestDemoBo {
    /**
     * 主键
     */
    @NotNull(message = "主键不能为空", groups = {EditGroup.class})
    private Long id;

    /**
     * 部门id
     */
    @NotNull(message = "部门id不能为空", groups = {AddGroup.class, EditGroup.class})
    private Long deptId;

    /**
     * 用户id
     */
    @NotNull(message = "用户id不能为空", groups = {AddGroup.class, EditGroup.class})
    private Long userId;

    /**
     * 排序号
     */
    @NotNull(message = "排序号不能为空", groups = {AddGroup.class, EditGroup.class})
    private Integer orderNum;

    /**
     * key键
     */
    @NotBlank(message = "key键不能为空", groups = {AddGroup.class, EditGroup.class})
    private String testKey;

    /**
     * 值
     */
    @NotBlank(message = "值不能为空", groups = {AddGroup.class, EditGroup.class})
    private String value;

}

2. controller

@RestController
@RequestMapping("/validator")
public class ValidatorController {

    @PostMapping("/add")
    public Dict add(@RequestBody TestDemoBo bo) {
        // 使用校验工具校验 @Validated(AddGroup.class) 注解
        // 用于非 controller 的地方校验对象
        ValidatorUtils.validate(bo, AddGroup.class);
        return Dict.create().set("msg", "success");
    }

    @PutMapping("/edit")
    public Dict edit(@Validated(EditGroup.class) @RequestBody TestDemoBo bo){
        return Dict.create().set("msg", "success");
    }
}

优雅进行字段校验

参数校验

@Validated 和 @Valid 的区别
