注意:我是框架新手，如有任何菜鸟错误，请原谅我。
背景信息:
在我的网络应用程序中，我使用电子邮件功能，这是通过使用 MailerClient 来完成的作为 sbt 库提供。
this 支持 MailerClient github 页面。
我使用 github 作为我的 git 存储库，因为这是一个团队项目。
我最初创建了该项目并推送到存储库，这是问题的开始。
<小时/>电子邮件支持说明(JAVA)(作为我采取的步骤的引用)
首先，要启用 Java 的电子邮件支持，需要执行几个步骤。
<强>1。添加SBT MailerClient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
<强>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。
<强>3。继续访问Java Usage标签
<强>4。在(您选择的)类中，添加代码:
@Inject
MailerClient mailerClient;
在此类中，MailerClient 对象被实例化并可用于发送电子邮件。
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:
检查我的分支(即从 github 中提取 webapp 项目)后，PlayFramework 没有检测到 MailerClient。
我可以确认 MailerClient 确实可以正常工作(被检测、实例化、发送电子邮件等)，就像它在推送到 github 之前所做的那样，并且此后没有进行任何更改。
澄清一下，这是未检测到插件/库的问题。
检查它是否确实存在:

启动 sbt 工具时，它确实解析了邮件程序插件

最佳答案
几天前我也遇到了同样的问题。我通过切换到以前版本的 play mailer(5.0)解决了我的问题。
下面是工作示例
build.sbt
libraryDependencies +="com.typesafe.play" %% "play-mailer" % "5.0.0-M1"
application.conf
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)
}
YourController.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);
}
}
路线
GET /mail controllers.YourController.Email
