java - 致命异常 MailerClient Play 2.5

Question

我正在尝试从我的 Play 应用程序发送电子邮件。 Email 对象由另一个类准备并传递给将发送电子邮件的 Controller 。然而，当尝试发送电子邮件时，会引发致命异常。 我的 Controller 设置如下:

public class UserController extends BaseController<User> {

@Inject
MailerClient mailerClient;

@Inject
public UserController(MailerClient client) {
    super(new UserService());
    mailerClient = client;
}

public Result create(){
    resourceForm = formFactory.form(User.class);
    Form<User> filledForm = resourceForm.bindFromRequest();
    if(filledForm.hasErrors()){
        return badRequest(filledForm.errorsAsJson());
    }
    User user = filledForm.get();
    Map emailMap = new HashMap<>();
    emailMap.put("email" , user.email);
    List<User> existingUser = service.where(emailMap);
    if(existingUser.size() != 0){
        return JsonResponse.JsonMessage(BAD_REQUEST , "This Email is already registered");
    }else{
        user.status = getStatus(DORMANT);
        user.save();
        UserRegistration registration = new UserRegistration(user);
        registration.save();

        Email email = EmailDispatcher.buildEmail(ACTIVATION , user.email , registration.link);
        mailerClient.send(email);

    }
    return ok(Json.toJson(user));
}

我的电子邮件配置设置为:

play.mailer{
  host = "smtp.gmail.com"
  port = 465
  ssl = yes
  user = "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="c4a1bca5a9b4a8a1eaa0a1b284a3a9a5ada8eaa7aba9" rel="noreferrer noopener nofollow">[email protected]</a>"
  password = password
}

在我的 Controller 中调用 mailerClient.send(email) 会导致引发以下异常:

[error] a.a.ActorSystemImpl - Uncaught fatal error from thread [application-akka.actor.default-dispatcher-2] shutting down ActorSystem [application]

        at play.core.routing.HandlerInvokerFactory$$anon$4.resultCall(HandlerInvoker.scala:156)

我使用的是 Mailer 版本 3.0.1，我的 build.sbt 如下:

name := """API"""

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayJava, PlayEbean)

scalaVersion := "2.11.7"

    libraryDependencies ++= Seq(
      javaJdbc,
      cache,
      javaWs,
      "mysql" % "mysql-connector-java" % "5.1.16",
      "de.svenkubiak" % "jBCrypt" % "0.4",
      "com.typesafe.play" %% "play-mailer" % "3.0.1"
    )

我在其他地方找不到类似的问题

Answer 1

将版本更改为 5.0.0-M1

libraryDependencies ++= Seq(
  javaJdbc,
  cache,
  javaWs,
  "mysql" % "mysql-connector-java" % "5.1.38",
  "de.svenkubiak" % "jBCrypt" % "0.4",
  "com.typesafe.play" %% "play-mailer" % "5.0.0-M1"
)

我刚刚像这样解决了几分钟，你迟到了1个版本，有4.0.0-M1和4.0.0的新版本用于play 2.4，但5.0.0-M1用于play 2.5， play-mailer 从今天起大约 26 天前更新。

编辑: 5.0.0版本发布你可以使用它:

"com.typesafe.play" %% "play-mailer" % "5.0.0"
