konfigurieren schrieb ich den folgenden Code für E-Mail-Funktionalität:wie eine E-Mail-Funktionalität in Play-Java 2.5.4
import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.HtmlEmail;
import play.mvc.Controller;
import play.mvc.Result;
public class MailController extends Controller {
public Result sendEmail() throws EmailException {
HtmlEmail email = new HtmlEmail();
String authuser = "[email protected]";
String authpwd = "XXXXXXX";
email.setSmtpPort(587);
email.setAuthenticator(new DefaultAuthenticator(authuser, authpwd));
email.setDebug(true);
email.setHostName("smtp.gmail.com");
email.setFrom("[email protected]", "SenderName");
email.setSubject("TestMail");
email.setHtmlMsg("<html><body><h1>welcome to u</h1></body></html>");
//email.addTo("[email protected]", "receiver name");
email.setTLS(true);
email.send();
return play.mvc.Results.ok("Success");
}
}
Aber ich habe Probleme (wie Ausnahmen erwischen in Netty) gegenüber.
Ich habe ein Plugin in bulid.sbt:
libraryDependencies ++= Seq(
"com.typesafe.play" %% "play-mailer" % "5.0.0-M1"
)
application.conf:
# Mailer
# ~~~~~
play.mailer {
host=smtpout.secureserver.net
port=587
ssl=false
tls=false
user=my username
password=my password
debug=false
mock=false
}
Dies ist einer der Fehler, die ich mit Blick auf bin:
[error] p.c.s.n.PlayRequestHandler - Exception caught in Netty
java.lang.NoClassDefFoundError: Could not initialize class play.api.http.DefaultHttpErrorHandler$

Wie kann ich das beheben?
meine application.config Datei ist als unten
# This is the main configuration file for the application.
# https://www.playframework.com/documentation/latest/ConfigFile
# ~~~~~
# Play uses HOCON as its configuration file format. HOCON has a number
# of advantages over other config formats, but there are two things that
# can be used when modifying settings.
#
# You can include other configuration files in this main application.conf file:
#include "extra-config.conf"
#
# You can declare variables and substitute for them:
#mykey = ${some.value}
#
# And if an environment variable exists when there is no other subsitution, then
# HOCON will fall back to substituting environment variable:
#mykey = ${JAVA_HOME}
## Akka
# https://www.playframework.com/documentation/latest/ScalaAkka#Configuration
# https://www.playframework.com/documentation/latest/JavaAkka#Configuration
# ~~~~~
# Play uses Akka internally and exposes Akka Streams and actors in Websockets and
# other streaming HTTP responses.
akka {
# "akka.log-config-on-start" is extraordinarly useful because it log the complete
# configuration at INFO level, including defaults and overrides, so it s worth
# putting at the very top.
#
# Put the following in your conf/logback.xml file:
#
# <logger name="akka.actor" level="INFO" />
#
# And then uncomment this line to debug the configuration.
#
#log-config-on-start = true
}
## Secret key
# http://www.playframework.com/documentation/latest/ApplicationSecret
# ~~~~~
# The secret key is used to sign Play's session cookie.
# This must be changed for production, but we don't recommend you change it in this file.
play.crypto.secret = "changeme"
## Modules
# https://www.playframework.com/documentation/latest/Modules
# ~~~~~
# Control which modules are loaded when Play starts. Note that modules are
# the replacement for "GlobalSettings", which are deprecated in 2.5.x.
# Please see https://www.playframework.com/documentation/latest/GlobalSettings
# for more information.
#
# You can also extend Play functionality by using one of the publically available
# Play modules: https://playframework.com/documentation/latest/ModuleDirectory
play.modules {
# By default, Play will load any class called Module that is defined
# in the root package (the "app" directory), or you can define them
# explicitly below.
# If there are any built-in modules that you want to disable, you can list them here.
#enabled += my.application.Module
# If there are any built-in modules that you want to disable, you can list them here.
#disabled += ""
}
## IDE
# https://www.playframework.com/documentation/latest/IDE
# ~~~~~
# Depending on your IDE, you can add a hyperlink for errors that will jump you
# directly to the code location in the IDE in dev mode. The following line makes
# use of the IntelliJ IDEA REST interface:
#play.editor=http://localhost:63342/api/file/?file=%s&line=%s
## Internationalisation
# https://www.playframework.com/documentation/latest/JavaI18N
# https://www.playframework.com/documentation/latest/ScalaI18N
# ~~~~~
# Play comes with its own i18n settings, which allow the user's preferred language
# to map through to internal messages, or allow the language to be stored in a cookie.
play.i18n {
# The application languages
langs = [ "en" ]
# Whether the language cookie should be secure or not
#langCookieSecure = true
# Whether the HTTP only attribute of the cookie should be set to true
#langCookieHttpOnly = true
}
## Play HTTP settings
# ~~~~~
play.http {
## Router
# https://www.playframework.com/documentation/latest/JavaRouting
# https://www.playframework.com/documentation/latest/ScalaRouting
# ~~~~~
# Define the Router object to use for this application.
# This router will be looked up first when the application is starting up,
# so make sure this is the entry point.
# Furthermore, it's assumed your route file is named properly.
# So for an application router like `my.application.Router`,
# you may need to define a router file `conf/my.application.routes`.
# Default to Routes in the root package (aka "apps" folder) (and conf/routes)
#router = my.application.Router
## Action Creator
# https://www.playframework.com/documentation/latest/JavaActionCreator
# ~~~~~
#actionCreator = null
## ErrorHandler
# https://www.playframework.com/documentation/latest/JavaRouting
# https://www.playframework.com/documentation/latest/ScalaRouting
# ~~~~~
# If null, will attempt to load a class called ErrorHandler in the root package,
#errorHandler = null
## Filters
# https://www.playframework.com/documentation/latest/ScalaHttpFilters
# https://www.playframework.com/documentation/latest/JavaHttpFilters
# ~~~~~
# Filters run code on every request. They can be used to perform
# common logic for all your actions, e.g. adding common headers.
# Defaults to "Filters" in the root package (aka "apps" folder)
# Alternatively you can explicitly register a class here.
#filters = my.application.Filters
## Session & Flash
# https://www.playframework.com/documentation/latest/JavaSessionFlash
# https://www.playframework.com/documentation/latest/ScalaSessionFlash
# ~~~~~
session {
# Sets the cookie to be sent only over HTTPS.
#secure = true
# Sets the cookie to be accessed only by the server.
#httpOnly = true
# Sets the max-age field of the cookie to 5 minutes.
# NOTE: this only sets when the browser will discard the cookie. Play will consider any
# cookie value with a valid signature to be a valid session forever. To implement a server side session timeout,
# you need to put a timestamp in the session and check it at regular intervals to possibly expire it.
#maxAge = 300
# Sets the domain on the session cookie.
#domain = "example.com"
}
flash {
# Sets the cookie to be sent only over HTTPS.
#secure = true
# Sets the cookie to be accessed only by the server.
#httpOnly = true
}
}
## Netty Provider
# https://www.playframework.com/documentation/latest/SettingsNetty
# ~~~~~
play.server.netty {
# Whether the Netty wire should be logged
#log.wire = true
# If you run Play on Linux, you can use Netty's native socket transport
# for higher performance with less garbage.
#transport = "native"
}
## WS (HTTP Client)
# https://www.playframework.com/documentation/latest/ScalaWS#Configuring-WS
# ~~~~~
# The HTTP client primarily used for REST APIs. The default client can be
# configured directly, but you can also create different client instances
# with customized settings. You must enable this by adding to build.sbt:
#
# libraryDependencies += ws // or javaWs if using java
#
play.ws {
# Sets HTTP requests not to follow 302 requests
#followRedirects = false
# Sets the maximum number of open HTTP connections for the client.
#ahc.maxConnectionsTotal = 50
## WS SSL
# https://www.playframework.com/documentation/latest/WsSSL
# ~~~~~
ssl {
# Configuring HTTPS with Play WS does not require programming. You can
# set up both trustManager and keyManager for mutual authentication, and
# turn on JSSE debugging in development with a reload.
#debug.handshake = true
#trustManager = {
# stores = [
# { type = "JKS", path = "exampletrust.jks" }
# ]
#}
}
}
## Cache
# https://www.playframework.com/documentation/latest/JavaCache
# https://www.playframework.com/documentation/latest/ScalaCache
# ~~~~~
# Play comes with an integrated cache API that can reduce the operational
# overhead of repeated requests. You must enable this by adding to build.sbt:
#
# libraryDependencies += cache
#
play.cache {
# If you want to bind several caches, you can bind the individually
#bindCaches = ["db-cache", "user-cache", "session-cache"]
}
## Filters
# https://www.playframework.com/documentation/latest/Filters
# ~~~~~
# There are a number of built-in filters that can be enabled and configured
# to give Play greater security. You must enable this by adding to build.sbt:
#
# libraryDependencies += filters
#
play.filters {
## CORS filter configuration
# https://www.playframework.com/documentation/latest/CorsFilter
# ~~~~~
# CORS is a protocol that allows web applications to make requests from the browser
# across different domains.
# NOTE: You MUST apply the CORS configuration before the CSRF filter, as CSRF has
# dependencies on CORS settings.
cors {
# Filter paths by a whitelist of path prefixes
#pathPrefixes = ["/some/path", ...]
# The allowed origins. If null, all origins are allowed.
#allowedOrigins = ["http://www.example.com"]
# The allowed HTTP methods. If null, all methods are allowed
#allowedHttpMethods = ["GET", "POST"]
}
## CSRF Filter
# https://www.playframework.com/documentation/latest/ScalaCsrf#Applying-a-global-CSRF-filter
# https://www.playframework.com/documentation/latest/JavaCsrf#Applying-a-global-CSRF-filter
# ~~~~~
# Play supports multiple methods for verifying that a request is not a CSRF request.
# The primary mechanism is a CSRF token. This token gets placed either in the query string
# or body of every form submitted, and also gets placed in the users session.
# Play then verifies that both tokens are present and match.
csrf {
# Sets the cookie to be sent only over HTTPS
#cookie.secure = true
# Defaults to CSRFErrorHandler in the root package.
#errorHandler = MyCSRFErrorHandler
}
## Security headers filter configuration
# https://www.playframework.com/documentation/latest/SecurityHeaders
# ~~~~~
# Defines security headers that prevent XSS attacks.
# If enabled, then all options are set to the below configuration by default:
headers {
# The X-Frame-Options header. If null, the header is not set.
#frameOptions = "DENY"
# The X-XSS-Protection header. If null, the header is not set.
#xssProtection = "1; mode=block"
# The X-Content-Type-Options header. If null, the header is not set.
#contentTypeOptions = "nosniff"
# The X-Permitted-Cross-Domain-Policies header. If null, the header is not set.
#permittedCrossDomainPolicies = "master-only"
# The Content-Security-Policy header. If null, the header is not set.
#contentSecurityPolicy = "default-src 'self'"
}
## Allowed hosts filter configuration
# https://www.playframework.com/documentation/latest/AllowedHostsFilter
# ~~~~~
# Play provides a filter that lets you configure which hosts can access your application.
# This is useful to prevent cache poisoning attacks.
hosts {
# Allow requests to example.com, its subdomains, and localhost:9000.
#allowed = [".example.com", "localhost:9000"]
}
}
## Evolutions
# https://www.playframework.com/documentation/latest/Evolutions
# ~~~~~
# Evolutions allows database scripts to be automatically run on startup in dev mode
# for database migrations. You must enable this by adding to build.sbt:
#
# libraryDependencies += evolutions
#
play.evolutions {
# You can disable evolutions for a specific datasource if necessary
#db.default.enabled = false
}
## Database Connection Pool
# https://www.playframework.com/documentation/latest/SettingsJDBC
# ~~~~~
# Play doesn't require a JDBC database to run, but you can easily enable one.
#
# libraryDependencies += jdbc
#
play.db {
# The combination of these two settings results in "db.default" as the
# default JDBC pool:
#config = "db"
#default = "default"
# Play uses HikariCP as the default connection pool. You can override
# settings by changing the prototype:
prototype {
# Sets a fixed JDBC connection pool size of 50
#hikaricp.minimumIdle = 50
#hikaricp.maximumPoolSize = 50
}
}
## JDBC Datasource
# https://www.playframework.com/documentation/latest/JavaDatabase
# https://www.playframework.com/documentation/latest/ScalaDatabase
# ~~~~~
# Once JDBC datasource is set up, you can work with several different
# database options:
#
# Slick (Scala preferred option): https://www.playframework.com/documentation/latest/PlaySlick
# JPA (Java preferred option): https://playframework.com/documentation/latest/JavaJPA
# EBean: https://playframework.com/documentation/latest/JavaEbean
# Anorm: https://www.playframework.com/documentation/latest/ScalaAnorm
#
db {
# You can declare as many datasources as you want.
# By convention, the default datasource is named `default`
# https://www.playframework.com/documentation/latest/Developing-with-the-H2-Database
#default.driver = org.h2.Driver
#default.url = "jdbc:h2:mem:play"
#default.username = sa
#default.password = ""
# You can turn on SQL logging for any datasource
# https://www.playframework.com/documentation/latest/Highlights25#Logging-SQL-statements
#default.logSql=true
}
#play.mailer {
# default.host=smtp.gmail.com
# default.port=587
# ssl=false
# default.tls=true
# default.user=.......gmail.com
# default.password=mypassword
# default.debug=true
# default.mock=false

Sie scheinen mit Java zu verwenden. Aber der DefaultHttpErrorHandler scheint der für Scala zu sein .. (beachte das Paket 'play.api.http' (scala) vs 'play.http' (java) – rethab
Ich habe etwas geändert und sehe meinen Code wie oben Verwenden Sie nie play.api.http und play.http, aber ich bin mit dem gleichen Problem konfrontiert.Wenn ich SMTP-Konfiguration in Java-Klasse schreiben Mails senden Bur Schreiben in app.conf Datei wir vor der Ausgabe –
Können Sie Ihre application.conf freigegeben? – rethab
