Jersey App Engine:实体验证不起作用

Jersey App Engine: entity validation not working

我正在使用 Google App Engine、Jersey、Objectify 和 Gson(以及其他一些小型库)构建应用程序。

我想使用 @Valid 注释在资源中进行验证。但是,似乎没有执行任何实际验证。特别是,当将 payee 设置为 "123"Entry 发布到 /entries/entries/nocheck 时,应用程序不会引发任何异常并且实体正在保存在数据存储中。

这是实体的片段:

@Entity
public class Entry {

  @Id
  private Long id;
  private LocalDate date;
  @com.sappenin.objectify.annotation.Money
  private Money amount;
  @NotNull @Pattern(regexp = "[a-zA-Z][a-zA-Z0-9]*") @Length(min = 5)
  private String payee;
  private String description;
  private String note;

  //...
}

这是资源的片段:

@Path("/entries")
@Produces(MediaType.APPLICATION_JSON)
public class TestApi {

  @POST
  @Consumes(MediaType.APPLICATION_JSON)
  public Response create(@Valid Entry entry) {
    OfyService.ofy().save().entities(entry).now();
    return Response.ok(entry).build();
  }

  @POST
  @Path("/nocheck")
  @Consumes(MediaType.APPLICATION_JSON)
  public Response createNoCheck(Entry entry) {
    OfyService.ofy().save().entities(entry).now();
    return Response.ok(entry).build();
  }

}

这是应用程序:

public class MyApplication extends ResourceConfig {

  public MyApplication() {
    packages(
            "it.newfammulfin.model",
            "it.newfammulfin.api",
            "it.newfammulfin.api.util");
  }

}

请注意 pom.xml 包含此依赖项:

<dependency>
  <groupId>org.glassfish.jersey.ext</groupId>
  <artifactId>jersey-bean-validation</artifactId>
  <version>2.22.1</version>
</dependency>

这会导致 due to the auto-discovery feature 无需进一步配置即可启用验证。

我错过了什么?

更新

我在资源中添加了一个显式验证实体的方法:

  @POST
  @Path("validate")
  @Consumes(MediaType.APPLICATION_JSON)
  public Response testValidate(@Valid Entry entry) {
    ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
    Validator validator = factory.getValidator();
    System.out.println("validator is "+validator.getClass().getName());
    System.out.println(validator.validate(entry));
    return Response.ok(entry).build();
  }

通过调用 validate() 的验证有效。然而,实际调用 testValidate() 之前的验证没有。 顺便说一句,我不得不在 Hibernate Validator 和 Google App Engine 之间使用 Apache BVal implementation of the JSR303 Bean Validation, because of some issues

在泽西 2.X 您必须注册您的分机。然而,验证似乎是个例外,如 here 所述。无论如何我都会尝试一下,看看你可以配置什么:

  • CommonProperties.FEATURE_AUTO_DISCOVERY_DISABLE
  • ServerProperties.FEATURE_AUTO_DISCOVERY_DISABLE
  • ServerProperties.BV_FEATURE_DISABLE

您的申请 class 可能如下所示:

public class MyApplication extends ResourceConfig {
  public MyApplication() {
    register(ValidationFeature.class);
    property(ServerProperties.BV_SEND_ERROR_IN_RESPONSE, true);
    property(ServerProperties.BV_DISABLE_VALIDATE_ON_EXECUTABLE_OVERRIDE_CHECK, true)
    packages(
            "it.newfammulfin.model",
            "it.newfammulfin.api",
            "it.newfammulfin.api.util");
  }
}

我通过仔细清理 pom.xml 并更新所有版本解决了这个问题。正确的依赖关系如下(我使用的是1.9.27版本的Google App Engine):

请注意最后两个,关于 juel, were needed to avoid this problem (see the comment concerning the message parameter): see also this related solved issue 关于 Google App Engine 和 juel 之间的不兼容性。
