Using Fuse for Dependency Injection in Swing

The fuse project for dependency injection can be found at https://fuse.dev.java.net.

The overview is quite simple and can be found at https://fuse.dev.java.net/gettingstarted.html.

in short, Fuse uses a text file containing resources and values to be injected into the object at run time.

The following code shows a very simple example of how to use fuse:

1: Create the Resource File

create the package test and create the file testfuse.resources in that package.

add the following line to testfuse.resources

	TestFuse.name=Jon Doe

When this resource file is applied by fuse, it will inject the value Jon Doe into the member name in the class TestFuse

2: Create the Java code to inject the resources

Create the class TestFuse.java to read the resource file and use fuse to inject the contents.

	package test;
	import org.jdesktop.fuse.InjectedResource;
	import org.jdesktop.fuse.ResourceInjector;

	public class TestFuse
	{
		@InjectedResource
		private String name;
	
		public String toString()
		{
			return this.getClass().getName()+"[name="+name+"]";
		}
	
		public static void main(String[] args)
		{		
			ResourceInjector.get().load(TestFuse.class.getResource("testfuse.resources"));
	
			TestFuse testFuse = new TestFuse();
			ResourceInjector.get().inject(testFuse);

			System.out.println(testFuse);
		}
	}
