Gestalt
A Java configuration library that allows you to build your configurations from multiple sources, merges them and convert them into an easy-to-use typesafe configuration class. A simple but powerful interface allows you to navigate to a path within your configurations and retrieve a configuration object, list, or a primitive value. -

README
Overview
cfg4j ("configuration for Java") is a configuration library for Java distributed apps (and more).
Features:
- Open source
- Easy to use
- Auto-reloads configuration
- Powerful configuration mechanisms (interface binding, multi-source support with fallback strategy, merging, ...)
- Distributed-environment friendly ( caching, support for multiple environments [test, preprod, prod], ...)
- Reads configuration from: Consul, Git repos (YAML and/or properties), Files, Classpath, ...
- Modern design
- Seamless integration with DI containers: Spring, Guice and others
- Exposes performance metrics by integration with Metrics library
- Extensible (see the list of plugins below)
- Heavily tested (99% code coverage)
- Well documented
- Java 8+ required

Quick start
Setting up dependency
Gradle
dependencies {
compile group: "org.cfg4j", name:"cfg4j-core", version: "4.4.1"
// For Consul integration
compile group: "org.cfg4j", name:"cfg4j-consul", version: "4.4.1"
// For git integration
compile group: "org.cfg4j", name:"cfg4j-git", version: "4.4.1"
}
Maven
<dependencies>
<dependency>
<groupId>org.cfg4j</groupId>
<artifactId>cfg4j-core</artifactId>
<version>4.4.1</version>
</dependency>
<!-- For Consul integration -->
<dependency>
<groupId>org.cfg4j</groupId>
<artifactId>cfg4j-consul</artifactId>
<version>4.4.1</version>
</dependency>
<!-- For git integration -->
<dependency>
<groupId>org.cfg4j</groupId>
<artifactId>cfg4j-git</artifactId>
<version>4.4.1</version>
</dependency>
</dependencies>
Usage
The fastest way to start working with cfg4j is to use a Git repository as a configuration store. To do that follow the steps:
- Use the following code in your application to connect to sample configuration source: ```java public class Cfg4jPoweredApplication {
// Change this interface to whatever you want public interface SampleConfig { Integer birthYear(); List friends(); URL homepage(); Map grades(); }
public static void main(String... args) { ConfigurationSource source = new GitConfigurationSourceBuilder() .withRepositoryURI("https://github.com/cfg4j/cfg4j-git-sample-config.git") .build();
ConfigurationProvider provider = new ConfigurationProviderBuilder()
.withConfigurationSource(source)
.build();
SampleConfig config = configurationProvider.bind("reksio", SampleConfig.class);
// Use it!
System.out.println(config.homepage());
}
}
* Optional steps
1. Fork the [configuration sample repository](https://github.com/cfg4j/cfg4j-git-sample-config).
2. Add your configuration to the "*application.properties*" file and commit the changes.
3. Update the code above to point to your fork.
