cnmuc :
In a JUnit test in a Play! 2.6.25 application executed in IntelliJ, I'm trying to inject a test config:Config into an app:Application created by Guice. But the app:Application does not contain the injected config. What am I doing wrong?
Config config = ConfigFactory.parseFile(new File("test.conf")).resolve();
// myapp.key resolved to "value"
String value = config.getString("myapp.key");
GuiceApplicationBuilder guiceApplicationBuilder = new GuiceApplicationBuilder();
guiceApplicationBuilder.withConfigLoader(environment -> ConfigFactory.load(config));
Application app = guiceApplicationBuilder.build();
// why myapp.key cannot be resolved?
app.config().getString("myapp.key");
test.conf
myapp.key = value
Also tried (without success):
guiceApplicationBuilder.loadConfig(config);
guiceApplicationBuilder.configure(config);
cbley :
You are actually discarding the Application Builder which has your custom config loader since the builder is an immutable data structure. Do it like this:
GuiceApplicationBuilder guiceApplicationBuilder = new GuiceApplicationBuilder()
.withConfigLoader(environment -> ConfigFactory.load(config));
or simply
GuiceApplicationBuilder guiceApplicationBuilder = new GuiceApplicationBuilder()
.configure(config);
When looking at the methods' signature you notice they all return (a new!) GuiceApplicationBuilder.
