springboot注解数据校验

springboot注解校验对象数据

1.方式一

import javax.validation.ConstraintViolation;
import javax.validation.ValidationException;
import javax.validation.Validator;
import java.util.Set;

public class ValidUtils {

    /**
     * 实体类参数有效性验证
     * @param bean 验证的实体对象
     * @param groups 验证组
     * @return 验证成功：返回true；验证失败：将错误信息添加到message中
     */
    public static void  validObject(Object bean, Validator validator, Class ...groups) {
        Set> constraintViolationSet = validator.validate(bean, groups);
        if (!constraintViolationSet.isEmpty()) {
            StringBuilder sb = new StringBuilder();
            for (ConstraintViolation violation: constraintViolationSet) {
                sb.append(violation.getMessage());
            }
            throw new ValidationException(sb.toString());
        }
    }
}

//自动装配到工厂
import org.hibernate.validator.HibernateValidator;

@Configuration
@EnableAutoConfiguration
@Slf4j
public class DefaultCommonConfiguration {
  @Bean
    public Validator validator() {
        ValidatorFactory validatorFactory = Validation.byProvider( HibernateValidator.class )
          
          .configure()
                .failFast( true )
                .buildValidatorFactory();
        Validator validator = validatorFactory.getValidator();

        return validator;
    }

}

public class OriginalRecord {
    private  @Valid BasicInfo basicInfo;
    有其他对象的,
    ,
    ,
    
}


@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
@Slf4j
public class BasicInfo {
    @NotBlank(message = "id is not null")
    @Size(max = 50, message = "id  length cannot be greater than 50")
    @SerializedName("id")
    }

import javax.validation.Validator;
import javax.validation.groups.Default;

@RestController
@Slf4j
@RequestMapping(value = "/api/v1111")
public class testController {

 @Resource
    private Validator validator;

@RequestMapping(value = "访问路由")
 public OrionResponse record( @RequestBody String originalBody) throws PassPermitException {
            //验证第三方数据
            ValidUtils.validObject(baseRecord, validator,  Default.class);

	    return "要返回的对象";

	    }

}

2.方式二

    @PostMapping(value = "/testModify")
    public StatusResponse batchModify(@Validated @RequestBody ModifyTestRequest request, BindingResult bindResult) {
  
        if (bindResult.hasErrors()) {
            StringBuffer sb = new StringBuffer();
            for (ObjectError err : bindResult.getAllErrors()) {
                if (sb.length() > 0) {
                    sb.append(",");
                }
                sb.append(((FieldError) err).getField());
            }
            throw new TestPassException(PARAM_INVALID, "param error", sb.toString());
        }
        return "返回结果"
    }
    

@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class ModifyTestRequest {
//对象用注解验证不能为空
    @NotEmpty
    private List codeIds;
     具体其他验证规整可以参考验证的一些文档 ,,,
