ConfigurationPropertiesFactory
The interface de.smartics.properties.api.config.app.ConfigurationPropertiesFactory defines which factory for configuration properties is to be used.
The main task for such a factory is to create ConfigurationProperties that provide access to property descriptors (static information provided by the declaration of properties) and to property values (dynamic information provided by the definition of properties).
Enterprise Applications
Typical implementations for enterprise applications are:
- de.smartics.properties.impl.config.ds.AutodetectDataSourceConfigurationPropertiesFactory - this is the implementation typically to select to access properties on supported SQL databases.
- de.smartics.properties.impl.config.ds.DataSourceConfigurationPropertiesFactory - provides access to properties in data sources.
Simple Applications
Typical implementations for simple applications are:
- de.smartics.properties.impl.config.classpath.ClasspathConfigurationPropertiesFactory - fetches the properties information from the classpath available at runtime. Use this factory for a small application where the distinction between different environments is not useful.
- de.smartics.properties.impl.config.properties.PropertiesConfigurationPropertiesFactory - provides configurations bases on properties instances. Use this factory for a small application where the distinction between different environments is not useful.
- de.smartics.properties.impl.config.resource.ResourceConfigurationPropertiesFactory - provides access to configuration information in Maven artifacts. Use this factory for a small application where the distinction between different environments is not useful.
Delegations
It is sometimes useful to add information or services by delegating to existing factory implementations. Here are examples of factories that use this technique:
- de.smartics.properties.admin.domain.service.RemoteConfigurationPropertiesManagementFactory - provides information about a remote repository that is used to access property information and delegates calls to access property information to a passed in factory instance.
