Java EE getting information about what environment the application is currently running

You can run a Java EE application in a test environment, a development environment or a production one.

How can I use Java code or XML to get hold of that information?

if ( ApplicationContext.inDevelopment() { // do this }

Obviously the above is not correct. But you get the point. How c开发者_高级运维an I do this?

there are many ways to achieve it.

• check ip address of the sever to decide which platform it is running on.

• add -D property into your server start script, in your program get
  the system property.

• for different platforms using different properties files. each
  properties file contains a "platform" property

• or if you are using maven to build your application, you can create
  profiles, to set property/attribute at building time.
