In the spring maven project, use hibernate validator to annotate the input parameter object of the formal verification method.
hibernate-validator version: 5.0.2.Final
validation-api version: 1.1.0.Final
There is an attribute named order_time in the model class annotated with @NotEmpty:
package com.emax.paycenter.dto.external;
import org.hibernate.validator.constraints.NotEmpty;
import org.hibernate.validator.constraints.URL;
import javax.validation.constraints.Min;
import javax.validation.constraints.NotNull;
import java.io.Serializable;
/**
* Scan QR code to pay Request Model
* Created by Yunlong on 2017/6/1.
*/
public class QRCodeRequest extends BaseRequest {
private static final long serialVersionUID = -3640955104188613350L;
/**
* order number
*/
@NotNull(message = "order_no cannot be empty!")
private String order_no;
/**
* Payment amount, in cents
*/
@Min(value = 1,message = "pay_money minimum value 1!")
public int pay_money;
/**
* The URL for receiving notifications from the payment center needs to be given an absolute path. The format within 255 characters is: http://wap.tenpay.com/tenpay.asp. Make sure that the payment center can access the address through http.
*/
@URL(protocol="http",message="notify_urlInvalid URL address!")
@NotNull(message = "notify_url cannot be empty!")
private String notify_url;
/**
* Order time (format: yyyyMMddHHmmss)
*/<strong>
@NotEmpty(message = "order_time cannot be empty!")
</strong>private String order_time;
/**
* product name
*/
@NotNull(message = "goods_name cannot be empty!")
private String goods_name;
/**
* Remark
*/
private String remark;
/**
* Valid for a few minutes
*/
private String valid_minutes;
/**
* Payment channel Kubao Pay, Qingdao CITIC
*/
@NotNull(message = "third_pay_platform cannot be empty!")
private String third_pay_platform;
/**
* Payment channel type (12: WeChat scan code, 22: Alipay scan code)
*/
@NotNull(message = "pay_channel cannot be empty!")
private int pay_channel;
//

}
BeanValidators tool class:
package com.emax.paycenter.utils;
import javax.validation.ConstraintViolation;
import javax.validation.ConstraintViolationException;
import javax.validation.Validator;
import java.util.Set;
/**
* JSR303 Validator (Hibernate Validator) tool class.
*
* ConstraintViolation contains information such as propertyPath, message and invalidValue.
* Provides various convert methods suitable for different i18n needs:
* 1. List<String>, String content is message
* 2. List<String>, String content is propertyPath + separator + message
* 3. Map<propertyPath, message>
*
* See wiki for details: https://github.com/springside/springside4/wiki/HibernateValidator
* @author calvin
* @version 2013-01-15
*/
public class BeanValidators {
/**
* Call the validate method of JSR303 and throw ConstraintViolationException when verification fails.
*/
@SuppressWarnings({ "unchecked", "rawtypes" })
public static void validateWithException(Validator validator, Object object, Class<?>... groups)
throws ConstraintViolationException {
Set<ConstraintViolation<Object>> constraintViolations = validator.validate(object, groups);
if (!constraintViolations.isEmpty()) {
StringBuffer sb=new StringBuffer();
for (ConstraintViolation constraintViolation : constraintViolations) {
sb.append(constraintViolation.getMessage());
}
throw new RuntimeException(sb.toString());
}
}<br>}
Write the following testcase method:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring/applicationContext.xml")
public class ValidatorTest {
@Autowired
private Validator validator;
@Test
public void notEmptyAttributeTest() throws Exception {
QRCodeRequest pojo=new QRCodeRequest();
pojo.setOrder_time("");
try {
BeanValidators.validateWithException(validator, pojo);
} catch (RuntimeException e) {
System.out.println("validerror:" + e.getMessage());
}
}
}
Executing testcase reports an error:

java.lang.NoClassDefFoundError: javax/el/ELContext
Solution:
- I asked colleagues for help and tried to introduce jstl, but it didn’t work.
- Properties should not be annotated with NotEmpty but should be annotated with NotBlank. (In fact, the verification item we need is NotBlank, not NotEmpty)
- Refer to http://blog.csdn.net/bsg_24/article/details/49494975 and reduce the version of hibernate validator to 4.3.1.Final.
