Question

在我的Wildfly 13 Server部署过程中，我收到NullPointerException。看来这仅在我使用@Email批注时发生。如果我不运行以下代码，则效果很好。您对如何解决此问题有任何想法吗？

@GET
@Path("/register")
@PermitAll
@Produces(MediaType.TEXT_PLAIN)
public Response register(@QueryParam("email") @Email @Unique(UserEmailUniqueConfirmer.class) String email, @QueryParam("password") @NotEmpty String password) {
    try {
        authenticationService.register(email, password);
        return Response.ok().build();

    } catch (UserEmailAlreadyInUseException e) {
        return Response.status(Status.BAD_REQUEST).build();
    }
}

请确保您的Wildfly服务器版本与JSR-380兼容。 hibernate-validator-6.x使用javax.validation:validation-api-2.0.x。

请检查服务器的类路径，如果在其中找到javax.validation:validation-api-1.x，则可以尝试以下解决方案：

将您的休眠验证器降级到基于javax.validation:validation-api-1.1.Final的{{3}}
将Wildfly服务器升级到与新的验证api兼容的新版本。您也可以尝试在服务器类路径中替换验证api jar，但如果有可用的版本，我希望使用正式版本。

如果决定使用JSR-380和@javax.validation.constraints.Email，请记住使用标准@org.hibernate.validator.constraints.Email而不是已弃用的hibernate-validator-6.x。

@Email验证注释会在部署中导致NullPointerException
