JSR-303 Bean Validation

接收数据的JAVA BEAN通常需要验证其中字段的正确性,如不准为空,符合EMAIL格式等。
JSR-303 Bean Validation则提供了这样的便捷。

只要在JAVA BEAN中需要验证的字段加@NotNull这种标签,然后在SERVISE中的输入参数中加@Valid标签,则就激活验证流程。
也可以编程的方式自己验证:
@MessageEndpoint
//@Validated
public class MqMessageCcdValidator {
    
    private static final Logger LOGGER = LoggerFactory.getLogger(MqMessageCcdValidator.class);
    
    @Autowired
    private Validator validator;
    
    @ServiceActivator
    public MqMessage<CcdRequest> validate(/* @Valid */ Message<MqMessage<CcdRequest>> requestMessage) {
        Set<ConstraintViolation<MqMessage<CcdRequest>>> set = validator.validate(requestMessage.getPayload());
        if(CollectionUtils.isNotEmpty(set)) {
            CompositeException compositeException = new CompositeException();
            set.forEach(
                constraintViolation -> {
                                            LOGGER.info("{}", constraintViolation);
                                            ReqInfoValidationException exception =
                                                    new ReqInfoValidationException(constraintViolation.getMessage());
                                            compositeException.addException(exception);
                                       }
            );
            throw new MessageHandlingException(requestMessage, compositeException);
        }
        
        return requestMessage.getPayload();
    }

}

自定义验证规则
可用标签来做,以下为验证手机号的规则:
import static java.lang.annotation.RetentionPolicy.RUNTIME;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.Target;

import javax.validation.Constraint;
import javax.validation.Payload;
import javax.validation.ReportAsSingleViolation;
import javax.validation.constraints.Pattern;

@Retention(RUNTIME)
@Target(value = { ElementType.FIELD, ElementType.PARAMETER, ElementType.ANNOTATION_TYPE })
@Constraint(validatedBy = {})
@ReportAsSingleViolation
@Pattern(regexp = "^1[3-9]\\d{9}$")
public @interface ChinaPhone {
    String message() default "Invalid Chinese mobile No.";
    Class<?>[] groups() default {};
    Class<? extends Payload>[] payload() default {};
}
