How do we tell the container that which profile is active now to pick up the right configurations. Where as you also do it in the class level. This example uses the method type annotation (Spring 4 improvements).
The syntax for this annotation is If a bean or method marked with annotation will be associated with that particular profile name. By using the annotation, a suitable data source will be invoked by the test Annotation
This example declares data source for dev and prod. I have written a very simple example to demonstrate the power of feature in Spring 4. Spring Profiles provide a way to segregate parts of your application configuration and make it only available in certain environments. This tutorial provide simple example for annotation. That gives more control and eliminate the need for creating multiple configuration files. Prior to Spring 4, only bean level annotation is supported by With Spring 4, this can be used in the method level. annotation helps developers to create multiple configurations details for different environments. List of Spring Tutorials : Spring annotation is introduced as part of the Spring Framework 3.1 release. The solution for the above problem is to create different profiles for each environment and enable them when you move to another environment. You would have to adjust the configurations to point to new environment details like Database, etc.
SPRING ANNOTATIONS CODE
The challenges arises when you want to move your source code to different environments.
In this scenario, the underlying resources (ie, database, file system, etc) for each environment would be different. If you are working for a real time projects, it is often basic requirement to have the different environments like development, testing and production. Also this tutorial explains the new improvements in the Spring 4.0 release and how it is different from the older releases.
