Trove best classes3/17/2023 This binding is functionally equivalent to the instance binding shown earlier You may define any scope.īind(GitHub.class). This binding is used when the type to be bound differs form the source type. This binding is used when the value to be bound is already known. Think of a binding as the basic unit of information that's required by the dependency injection (DI) container to determine whether it can resolve a dependency. Guice provides an API that enables you to define bindings between types. Java has its own standard in this regard: JSR 330.There are many implementations available for this JSR, but we'll stick with Google Guice because it's the reference implementation. In this day and age, it's difficult to think of building an application without using dependency injection. Notify the UI of new results, inside the UI thread.Issue the REST call on a background thread.Build an HTTP client that can query GitHub's API.In order to build this application, we have to tackle the following tasks at the very least: The application can present a dialog box if for any reason an error occurs during the execution of the REST call, as shown in Figure 3.įigure 3. The application looks like Figure 1 and Figure 2:įigure 2. For now, we'll parse the first page only, leaving pagination to the next installment in the series. GitHub's API will automatically paginate the results, providing enough information in the response headers so they can be used to determine how to navigate to subsequent pages. Results may be paginated if the queried organization contains more than 30 repositories. * additional repositories if they exist */ This API is explained here basically, what you do is issue a GET call such as this:Īnd you get a JSON payload as the result, which looks similar to Listing 1: We'll leave the authentication concern for another time, which means we'll pick a simple operation, for example, querying the available repositories for a particular organization. Some of them require authentication using either basic authentication or an OAuth2 token. There are many operations we can choose from. We'll pick GitHub's API because it's well documented and straightforward. There are many openly available REST APIs to be found on the web these days. The full source code is also available under the GP元 license at javatrove/github-api-01. Please let me know through your comments if you want to know more about the JavaFX internals. However JavaFX is not the main concern for this article thus, it will be kept to a minimum for now. I've chosen JavaFX as the UI technology because it's very easy to get started with it, and also doing that keeps the whole application centered in Java-based technologies. We'll begin this adventure by attempting to solve the following problem: query a REST-based API and present the results in a JavaFX application. That being said, the code examples should be seen as guides rather than canonical implementations that must be followed to the letter. The code examples presented in this series strive to be small enough to be comprehensible while still showing the power of the chosen libraries. It's worth noting that, like with many things in life, there are no silver bullets, nor is there a single, perfect way to reach a specific goal. The goal of this series is to have a positive impact on Java developers' productivity and enhance the development experience by presenting these libraries in the context of useful examples and shedding some light on the not-so-well-known libraries that abound. Some of these libraries are well known and used by many in their daily work others have yet to break into the spotlight. The Java landscape is covered with thousands of libraries and tools that make working in the Java space a much better experience. Hello! Welcome to the first part of "The Java Trove" series.
