This is your new Play application
=================================
This file will be packaged with your application when using `activator dist`.
There are several demonstration files available in this template.
Controllers
===========
- HomeController.java:
Shows how to handle simple HTTP requests.
- AsyncController.java:
Shows how to do asynchronous programming when handling a request.
- CountController.java:
Shows how to inject a component into a controller and use the component when
handling requests.
Components
==========
- Module.java:
Shows how to use Guice to bind all the components needed by your application.
- Counter.java:
An example of a component that contains state, in this case a simple counter.
- ApplicationTimer.java:
An example of a component that starts when the application starts and stops
when the application stops.
Filters
=======
- Filters.java:
Creates the list of HTTP filters used by your application.
- ExampleFilter.java
A simple filter that adds a header to every response.

# 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

#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

This is your new Play application
=================================
This file will be packaged with your application when using `activator dist`.
There are several demonstration files available in this template.
Controllers
===========
- HomeController.java:
Shows how to handle simple HTTP requests.
- AsyncController.java:
Shows how to do asynchronous programming when handling a request.
- CountController.java:
Shows how to inject a component into a controller and use the component when
handling requests.
Components
==========
- Module.java:
Shows how to use Guice to bind all the components needed by your application.
- Counter.java:
An example of a component that contains state, in this case a simple counter.
- ApplicationTimer.java:
An example of a component that starts when the application starts and stops
when the application stops.
Filters
=======
- Filters.java:
Creates the list of HTTP filters used by your application.
- ExampleFilter.java
A simple filter that adds a header to every response.
