= Spring Session - Grails
|
||||
Eric Helgeson
|
||||
:toc:
|
||||
|
||||
This guide describes how to use Spring Session to transparently leverage Redis to back a web application's `HttpSession` when you use Grails 3.1
|
||||
|
||||
NOTE: Grails 3.1 is based off spring boot 1.3, so much of the advanced configuration and options can be found in the Boot docs as well.
|
||||
|
||||
NOTE: You can find the completed guid in the <<grails3-sample, Grails 3 sample application>>.
|
||||
|
||||
== Updating Dependencies
|
||||
|
||||
Before you use Spring Session, you must update your dependencies.
|
||||
We assume you are working with a working Grails 3.1 web profile.
|
||||
You must add the following dependencies:
|
||||
|
||||
====
|
||||
.build.gradle
|
||||
[source,groovy]
|
||||
[subs="verbatim,attributes"]
|
||||
----
|
||||
dependencies {
|
||||
compile 'org.springframework.boot:spring-boot-starter-redis'
|
||||
compile 'org.springframework.session:spring-session:{spring-session-version}'
|
||||
}
|
||||
----
|
||||
====
|
||||
|
||||
ifeval::["{version-snapshot}" == "true"]
|
||||
Since we use a SNAPSHOT version, we need to ensure to add the Spring Snapshot Maven Repository.
|
||||
You must have the following in your build.gradle:
|
||||
|
||||
====
|
||||
.build.gradle
|
||||
[source,groovy]
|
||||
----
|
||||
repositories {
|
||||

|
||||

|
||||

|

}
|
||||
----
|
||||
====
|
||||
endif::[]
|
||||
|
||||
ifeval::["{version-milestone}" == "true"]
|
||||
Since we use a Milestone version, we need to add the Spring Milestone Maven Repository.
|
||||
You must have the following in your build.gradle:
|
||||
|
||||
====
|
||||
.build.gradle
|
||||
[source,groovy]
|
||||

[[grails3-redis-configuration]]
|
||||
== Configuring the Redis Connection
|
||||
|
||||
Spring Boot automatically creates a `RedisConnectionFactory` that connects Spring Session to a Redis Server on localhost on port 6379 (default port).
|
||||
In a production environment you need to ensure to update your configuration to point to your Redis server.
|
||||
For example, you can include the following in your application.yml:
|
||||
|
||||
====
|
||||
.grails-app/conf/application.yml
|
||||
[source,yml]
|
||||
----
|
||||
spring:
|
||||
redis:
|
||||
host: localhost
|
||||
password: secret
|
||||
port: 6397
|
||||
----
|
||||
====
|
||||
|
||||
For more information, see the https://docs.spring.io/spring-boot/docs/{spring-boot-version}/reference/htmlsingle/#boot-features-connecting-to-redis[Connecting to Redis] portion of the Spring Boot documentation.

||||
[[grails3-sample]]
|
||||
== Grails 3 Sample Application
|
||||
|
||||
The Grails 3 Sample Application demonstrates how to use Spring Session to transparently leverage Redis to back a web application's `HttpSession` when using Grails.
|
||||
|
||||
[[grails3-running]]
|
||||
=== Running the Grails 3 Sample Application
|
||||
|
||||
You can run the sample by obtaining the {download-url}[source code] and invoking the following command:
|
||||
|
||||
----
|
||||
$ ./gradlew :spring-session-sample-misc-grails3:bootRun
|
||||
----
|
||||
|
||||
NOTE:For the sample to work, you must https://redis.io/download[install Redis 2.8+] on localhost and run it with the default port (6379).
|
||||
Alternatively, you can update the `RedisConnectionFactory` to point to a Redis server.
|
||||
Another option is to use https://www.docker.com/[Docker] to run Redis on localhost.
|
||||
See https://hub.docker.com/_/redis/[Docker Redis repository] for detailed instructions.
|
||||
|
||||
You should now be able to access the application at http://localhost:8080/test/index
|
||||
|
||||
[[grails3-explore]]
|
||||
=== Exploring the `security` Sample Application
|
||||
|
||||
You can now try using the application. Enter the following to log in:
|
||||
|
||||
* *Username* _user_
|
||||
* *Password* _password_
|
||||
|
||||
Now click the *Login* button.
|
||||
You should now see a message indicating that your are logged in with the user entered previously.
|
||||
The user's information is stored in Redis rather than Tomcat's `HttpSession` implementation.
|
||||
|
||||
[[grails3-how]]
|
||||
=== How Does It Work?
|
||||
|
||||
Instead of using Tomcat's `HttpSession`, we persist the values in Redis.
|
||||
Spring Session replaces the `HttpSession` with an implementation that is backed by Redis.
|
||||
When Spring Security's `SecurityContextPersistenceFilter` saves the `SecurityContext` to the `HttpSession`, it is then persisted into Redis.
|
||||
|
||||
When a new `HttpSession` is created, Spring Session creates a cookie named `SESSION` in your browser.
|
||||
That cookie contains the ID of your session.
|
||||
You can view the cookies (with https://developers.google.com/web/tools/chrome-devtools/manage-data/cookies[Chrome] or https://developer.mozilla.org/en-US/docs/Tools/Storage_Inspector[Firefox]).
|
||||
|
||||
You can remove the session by using redis-cli.
|
||||
For example, on a Linux based system you can type the following:
|
||||
|
||||
====
|
||||
----
|
||||
$ redis-cli keys '*' | xargs redis-cli del
|
||||
----
|
||||
====
|
||||
|
||||
TIP: The Redis documentation has instructions for https://redis.io/topics/quickstart[installing redis-cli].
|
||||
|
||||
Alternatively, you can also delete the explicit key.
|
||||
To do so, enter the following into your terminal, being sure to replace `7e8383a4-082c-4ffe-a4bc-c40fd3363c5e` with the value of your `SESSION` cookie:
|
||||
|
||||
====
|
||||
----
|
||||
$ redis-cli del spring:session:sessions:7e8383a4-082c-4ffe-a4bc-c40fd3363c5e
|
||||
----
|
||||
====
|
||||
|
||||
Now you can visit the application at http://localhost:8080/test/index and see that we are no longer authenticated.
|
||||
|
||||
NOTE: Spring Session does not work with Grails flash scope without additional work.
|
||||
See https://stackoverflow.com/a/43311427 for an explanation.
