CUBA Platform. Developer's Manual
4.2.6. Infrastructure Interfaces

The interface helps to obtain references to configuration interfaces.

Examples:

// field injection

@Inject
protected Configuration configuration;
...
String tempDir = configuration.getConfig(GlobalConfig.class).getTempDir();

// setter injection

protected GlobalConfig globalConfig;

@Inject
public void setConfiguration(Configuration configuration) {
    this.globalConfig = configuration.getConfig(GlobalConfig.class);
}

// location

String tempDir = AppBeans.get(Configuration.class).getConfig(GlobalConfig.class).getTempDir();
