-This guide walks you through the steps for scheduling tasks with Spring.
-
-== What you'll build

-You'll build an application that prints out the current time every five seconds using Spring's `@Scheduled` annotation.
-
-== What you'll need

-== Create a scheduled task
-Now that you've set up your project, you can create a scheduled task.
-
-`src/main/java/hello/ScheduledTasks.java`
-[source,java]
-----
-include::complete/src/main/java/hello/ScheduledTasks.java[]
-----
-
-The `Scheduled` annotation defines when a particular method runs.
-NOTE: This example uses `fixedRate`, which specifies the interval between method invocations measured from the start time of each invocation. There are https://docs.spring.io/spring/docs/{spring_version}/spring-framework-reference/html/scheduling.html#scheduling-annotation-support-scheduled[other options], like `fixedDelay`, which specifies the interval between invocations measured from the completion of the task. You can also https://docs.spring.io/spring/docs/{spring_version}/javadoc-api/org/springframework/scheduling/support/CronSequenceGenerator.html[use `@Scheduled(cron=". . .")` expressions for more sophisticated task scheduling].
-
-== Enable Scheduling
-
-Although scheduled tasks can be embedded in web apps and WAR files, the simpler approach demonstrated below creates a standalone application. You package everything in a single, executable JAR file, driven by a good old Java `main()` method.
-
-`src/main/java/hello/Application.java`
-[source,java]
-----
-include::complete/src/main/java/hello/Application.java[]

-
-https://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#scheduling-enable-annotation-support[`@EnableScheduling`] ensures that a background task executor is created. Without it, nothing gets scheduled.

-

-
-
-
-Logging output is displayed and you can see from the logs that it is on a background thread. You should see your scheduled task fire every 5 seconds:
-
-....

-
-== Summary
-
-Congratulations! You created an application with a scheduled task. Heck, the actual code was shorter than the build file! This technique works in any type of application.
