playframework未检测到java mailerclient

3 周 Questions & Answers 160

注意：我是框架新手，请原谅我犯的任何新手错误

背景信息：

在我的webapp中，我使用电子邮件功能，这是通过使用作为sbt库提供的MailerClient实现的

MailerClient在thisgithub页面上受支持

我使用github作为我的git存储库，因为这是一个团队项目

我最初创建了项目并将其推送到存储库，这是问题的开始

电子邮件支持说明（JAVA）（作为我所采取步骤的参考）

首先，为了支持Java的电子邮件，需要采取一些步骤

1。添加SBT邮件客户端库

添加行

libraryDependencies += "com.typesafe.play" %% "play-mailer" % "6.0.1" libraryDependencies += "com.typesafe.play" %% "play-mailer-guice" % "6.0.1"

到projectRoot/build.sbt文件

2。配置MailerClient

然后在projectRoot/conf/application.conf文件中配置MailerClient端口等

github页面上给出的示例：

play.mailer { host = "example.com" // (mandatory) port = 25 // (defaults to 25) ssl = no // (defaults to no) tls = no // (defaults to no) tlsRequired = no // (defaults to no) user = null // (optional) password = null // (optional) debug = no // (defaults to no, to take effect you also need to set the log level to "DEBUG" for the application logger) timeout = null // (defaults to 60s in milliseconds) connectiontimeout = null // (defaults to 60s in milliseconds) mock = no // (defaults to no, will only log all the email properties instead of sending an email) }

我的位于application.conf文件的底部，因为它不构成任何其他树前缀的一部分

3。转到Java Usage标记

4。在类内部（由您选择），添加代码：

@Inject MailerClient mailerClient;

在这个类中，MailerClient对象被实例化，可以用来发送电子邮件

使用Github页面中的给定示例，创建email对象：

String cid = "1234"; Email email = new Email() .setSubject("Simple email") .setFrom("Mister FROM <from@email.com>") .addTo("Miss TO <to@email.com>") // adds attachment .addAttachment("attachment.pdf", new File("/some/path/attachment.pdf")) // adds inline attachment from byte array .addAttachment("data.txt", "data".getBytes(), "text/plain", "Simple data", EmailAttachment.INLINE) // adds cid attachment .addAttachment("image.jpg", new File("/some/path/image.jpg"), cid) // sends text, HTML or both... .setBodyText("A text message") .setBodyHtml("<html><body><p>An <b>html</b> message with cid <img src=\"cid:" + cid + "\"></p></body></html>");

然后使用mailerClient发送电子邮件：

mailerClient.send(email);

问题：

在签出我的分支（即它从github中提取webapp项目）之后，PlayFramework没有检测到MailerClient

我可以确认，MailerClient在推送到github之前就已经执行了工作（被检测、实例化、发送电子邮件等），此后没有进行任何更改

澄清一下，这是插件/库没有被检测到的问题

检查它是否确实存在：

09:15:08 ✔ cybex@arch-laptop ~/.ivy2 $ find | grep mailer ./cache/com.typesafe.play/play-mailer_2.12 ./cache/com.typesafe.play/play-mailer_2.12/ivy-6.0.1.xml.original ./cache/com.typesafe.play/play-mailer_2.12/ivydata-6.0.1.properties ./cache/com.typesafe.play/play-mailer_2.12/ivy-6.0.1.xml ./cache/com.typesafe.play/play-mailer_2.12/jars ./cache/com.typesafe.play/play-mailer_2.12/jars/play-mailer_2.12-6.0.1.jar ./cache/com.typesafe.play/play-mailer_2.12/srcs ./cache/com.typesafe.play/play-mailer_2.12/srcs/play-mailer_2.12-6.0.1-sources.jar ./cache/com.typesafe.play/play-mailer-guice_2.12 ./cache/com.typesafe.play/play-mailer-guice_2.12/ivy-6.0.1.xml.original ./cache/com.typesafe.play/play-mailer-guice_2.12/ivydata-6.0.1.properties ./cache/com.typesafe.play/play-mailer-guice_2.12/ivy-6.0.1.xml ./cache/com.typesafe.play/play-mailer-guice_2.12/jars ./cache/com.typesafe.play/play-mailer-guice_2.12/jars/play-mailer-guice_2.12-6.0.1.jar ./cache/com.typesafe.play/play-mailer-guice_2.12/srcs ./cache/com.typesafe.play/play-mailer-guice_2.12/srcs/play-mailer-guice_2.12-6.0.1-sources.jar

启动sbt工具时，它会解析mailer plugin

//... [info] Resolving com.typesafe.play#play-mailer_2.12;6.0.1 ... [info] Resolving org.apache.commons#commons-email;1.5 ... [info] Resolving com.sun.mail#javax.mail;1.5.6 ...

几天前我也遇到过同样的问题。我通过切换到play mailer的早期版本（5.0）解决了我的问题

下面是工作示例

构建。sbt

libraryDependencies +="com.typesafe.play" %% "play-mailer" % "5.0.0-M1"

应用程序。形态

play.mailer {
  host="smtp.gmail.com"
  port=465
  ssl=yes
  tls=no
  user="youremail@gmail.com"
  password="password"
  debug=no
  timeout=1000
  connectiontimeout=1000
  mock=no
  // (defaults to no, will only log all the email properties instead of sending an email)
}

您的控制器。java

public class YourController extends Controller {

private final MailerClient mailer ;

    @Inject
    public EventUser(MailerClient mailer) {
        this.mailer = mailer;
    }

public Result Email()
    {
        sendMail("Donald.Trump@gmail.com");
        return ok("done");
    }


private void sendMail(String userEmail)
    {

        Email email = new Email()
                .setSubject("BLah Blah Messsage ")
                .setFrom("")
                .addTo(" <"+userEmail+">")
                // adds attachment
                .setBodyText("Please register to Event at ");
        //.setBodyHtml("<html><body><p>An <b>html</b> message with cid <img src=\"cid:" + cid + "\"></p></body></html>");
        if(mailer!=null)
            mailer.send(email);
    }

}
