spring maven项目，使用hibernate validator 注解形式校验客户端的请求参数。
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互联网访问该地址
*/
@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
*/ }
编写如下testcase方法：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring/applicationContext.xml")
public class ValidatorTest {
@Autowired
private Validator validator; @Test
public void NotEmptyTest() throws Exception {
QRCodeRequest request=new QRCodeRequest();
request.setOrder_time(""); try {
BeanValidators.validateWithException(validator, request);
} catch (RuntimeException e) {
System.out.println("validerror:" + e.getMessage());
}
}
}
run时报错：

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。
