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。
