spring@valid不工作

Question

我发送了一个带有“postman”的“application/json”类型的POST请求，将param“phone”设置为空字符串，正常情况下应该为注释“@notempty”打印错误，但是，它没有打印任何内容，也没有很好地工作。

  @RequestMapping(value = "verify_smscode", method = RequestMethod.POST)
  @ResponseBody
  public ResponseDto verifySmsCode(HttpServletRequest request,
      @Valid @RequestBody VerifySmsCodeParam params, Errors errors) {
    if(errors.hasErrors()) {
      System.out.println("error");
    }

    boolean success = userService.verifySmsCode(params.getPhone(), params.getSmsCode());

    Map<String, Object> result = new HashMap<>();
    result.put("status", success);
    return new ResponseDto(result);
  }

@Data
@NoArgsConstructor
public class VerifySmsCodeParam {

  @NotEmpty //import org.hibernate.validator.constraints.NotEmpty;
  private String phone;

  @NotEmpty
  private String smsCode;
}

SpringMVCConfig：

@Configuration
@ComponentScan(basePackages="com.shit.voiceshare")
@EnableWebMvc
public class SpringMvcConfig extends WebMvcConfigurerAdapter {
  @Override
  public Validator getValidator() {
    LocalValidatorFactoryBean localValidatorFactoryBean = new LocalValidatorFactoryBean();
    localValidatorFactoryBean.setProviderClass(HibernateValidator.class);
    return localValidatorFactoryBean;
  }
}

Answer 1

您可能错过了依赖项。

<dependency>
   <groupId>javax.validation</groupId>
   <artifactId>validation-api</artifactId>
</dependency>
<dependency>
   <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator</artifactId>
</dependency>

此外，请确保正确导入NotNull。

import javax.validation.constraints.NotNull;
