我在部署 Wildfly 13 服务器期间遇到 NullPointerException。似乎只有当我使用 @Email 注释时才会发生这种情况。
如果我在没有它的情况下运行以下代码，它工作得很好。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();
}
}

最佳答案
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。
请检查您服务器的类路径，如果您发现 javax.validation:validation-api-1.x ，那么您可以尝试以下解决方案:
- 将您的 hibernate validator 降级为 version 5它基于
javax.validation:validation-api-1.1.Final - 将您的 Wildfly 服务器升级到与新验证 API 兼容的新版本。您也可以尝试替换服务器类路径中的验证 api jar，但我更愿意使用官方版本(如果有)。
如果您决定使用JSR-380 和 hibernate-validator-6.x。
