Addon: Distinct configuration values by environment

[mmartinez]

Hi all !

GvNIX team is finishing our dynamic configurations addon to simplify use and allow export to maven profiles.

Here an example:

# Create pet clinic example application
script --file clinic.roo

# Create a development configuration
configuration create --name dev

# Make some properties available for all configurations 
configuration property add --name database.url
configuration property add --name hibernate.hbm2ddl.auto
configuration property add --name log4j.rootLogger

# Set property values distinct than default for development configuration
configuration property value --configuration dev --property database.url --value jdbc:hsqldb:mem:mydevdb

# Check configurations
configuration list

# Write configurations to project
configuration export

# Create a production configuration
configuration create --name pro

# Set property values distinct than default for production configuration 
configuration property value --configuration pro --property database.url --value jdbc:hsqldb:file:myprodb
configuration property value --configuration pro --property hibernate.hbm2ddl.auto --value update
configuration property value --configuration pro --property log4j.rootLogger --value "ERROR, stdout"

# Write configurations to project
configuration export

Then you can run the application with distinct profiles:

* mvn clean tomcat:run -P dev
* mvn clean tomcat:run -P pro

Some feedback ?

Does this overlap at all with the profile support coming up in Spring 3.1?

Addon is independent of the configuration management system.

Addon commands only allows easily define configurations, properties and values. The information about each configuration is stored as metadata in an internal format.

Currently the addon has a command to export the configuration to maven profiles, but could be extended to export ant profiles, spring profiles, etc.

roo> ...

~.web roo> configuration create --name dev
Updated SRC_MAIN_RESOURCES/dynamic-configuration.xml
Configuration created with currently available properties
Updated SRC_MAIN_RESOURCES/dynamic-configuration.xml

(use 'configuration property add' to make a property available for all configurations

~.web roo> configuration property add --name database.url
Updated SRC_MAIN_RESOURCES/dynamic-configuration.xml
Updated SRC_MAIN_RESOURCES/dynamic-configuration.xml
Property available for all configurations
(use 'configuration property value' to set property new values)
