Using Google Guice to inject java properties

Question

I want to use google guice to make properties available in all classes of my application. I defined a Module which loads and binds the properties file Test.properties.<

Answer 1

guice-config

Usage example: At first we have a properties file 'config.properties':

test.key=test value

And we want to inject this value like this:

@Inject
@Config( Property.TEST_KEY )
private String injectedValue;

We need to load contents of file 'config.properties' into java.util.Properties and pass it to Config module:

Properties props = new Properties();
props.load(...);

Module configModule = new ConfigModule( props, Property.values() ); ... and injecting:

Injector injector = Guice.createInjector( configModule );
TestClass testClass = injector.getInstance( TestClass.class );
String injectedValue = testClass.getInjectedValue();

injected value will be 'test value'...
