hibernate.validator.constraints.NotEmpty校验请求参数报错java.lang.NoClassDefFoundError: javax/el/PropertyNotFoundException

spring maven 项目，使用 hibernate validator 注解形式校验方法的入参对象。

hibernate-validator 版本：5.0.2.Final

validation-api 版本：1.1.0.Final

model 类中有个名为 order_time 的属性用 @NotEmpty 注解：

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;
/**


扫码支付 Request Model


Created by 云龙 on 2017/6/1.
*/
public class QRCodeRequest extends BaseRequest {
private static final long serialVersionUID = -3640955104188613350L;
/**

订单号
*/
@NotNull(message = "order_no 不能为空!")
private String order_no;
/**
支付金额，以分为单位
*/
@Min(value = 1,message = "pay_money 最小值 1!")
public int pay_money;
/**
接收支付中心通知的 URL，需给绝对路径，255 字符内格式如:http://wap.tenpay.com/tenpay.asp，确保支付中心能通过 http 访问该地址
*/
@URL(protocol="http",message="notify_url 无效的 URL 地址!")
@NotNull(message = "notify_url 不能为空!")
private String notify_url;
/**
订单时间（格式：yyyyMMddHHmmss）
*/
@NotEmpty(message = "order_time 不能为空!")
private String order_time;
/**
商品名称
*/
@NotNull(message = "goods_name 不能为空!")
private String goods_name;
/**
备注
*/
private String remark;
/**
几分钟有效
*/
private String valid_minutes;
/**
支付渠道 酷宝支付, 青岛中信
*/
@NotNull(message = "third_pay_platform 不能为空!")
private String third_pay_platform;
/**
支付通道类型（12：微信扫码，22：支付宝扫码）
*/
@NotNull(message = "pay_channel 不能为空!")
private int pay_channel;

//
getter/setter （略）


}

BeanValidators 工具类：

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) 工具类.



ConstraintViolation 中包含 propertyPath, message 和 invalidValue 等信息.


提供了各种 convert 方法，适合不同的 i18n 需求:



List<String>, String 内容为 message




List<String>, String 内容为 propertyPath + separator + message




Map<propertyPath, message>

@version 2013-01-15
*/
public class BeanValidators {
/**

调用 JSR303 的 validate 方法, 验证失败时抛出 ConstraintViolationException.
*/
@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());
}

}
}

编写如下 testcase 方法：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring/applicationContext.xml")
public class ValidatorTest {
    @Autowired
    private Validator validator;
@Test
</span><span style="color: rgba(0, 0, 255, 1)">public</span> <span style="color: rgba(0, 0, 255, 1)">void</span> notEmptyAttributeTest() <span style="color: rgba(0, 0, 255, 1)">throws</span><span style="color: rgba(0, 0, 0, 1)"> Exception {
    QRCodeRequest pojo</span>=<span style="color: rgba(0, 0, 255, 1)">new</span><span style="color: rgba(0, 0, 0, 1)"> QRCodeRequest();
    <span style="background-color: rgba(255, 255, 0, 1)">pojo.setOrder_time(</span></span><span style="background-color: rgba(255, 255, 0, 1)">""<span style="color: rgba(0, 0, 0, 1)">);
    
    </span></span><span style="color: rgba(0, 0, 255, 1)">try</span><span style="color: rgba(0, 0, 0, 1)"> {
        BeanValidators.validateWithException(validator, pojo);
    } </span><span style="color: rgba(0, 0, 255, 1)">catch</span><span style="color: rgba(0, 0, 0, 1)"> (RuntimeException e) {
        System.out.println(</span>"validerror:" +<span style="color: rgba(0, 0, 0, 1)"> e.getMessage());
    }
}

}

执行 testcase 报错：

java.lang.NoClassDefFoundError: javax/el/ELContext

解决办法：

找同事协助，尝试引入 jstl，不奏效。
属性不用 NotEmpty 注解，改用 NotBlank 注解。（其实，我们所需的验证项正是 NotBlank，而非 NotEmpty）
参考 http://blog.csdn.net/bsg_24/article/details/49494975，将 hibernate validator 的版本降到 4.3.1.Final。
