![]() ![]() I'm going to use this template for our demo. I have created one template and uploaded it to eDocGen. As per the single-responsibility principle, the login service is only responsible for token generation. Login service is responsible for token generation. We can use EH cache (in-memory) or Radis (Distributed) and there are broadly used. I'm gonna use an in-memory cache using PassiveExpireMap from Apache's common-collections4. You should be asking me What kind of cache I'm using. And I'm going to cache the token for 20 mins and regenerate it again. In order to generate the documents, we need an access token to hit the eDocGen's API. Other services, DTO and exceptions can be found here.EmailService - Handles sending emails to the user.GeneralDocumentService - Handles document-related services from DocumentController. ![]() LoginService - Handle token generation for eDocGen.DocumentController - Handle All document-related API calls.Run the Application.java file to start the web server. Add commons-collections4for the token cache using the expiring map.If not, you can kick it using MVN install. Import the project into your IDE and soon after the dependencies with start downloading.Lombok: Annotations for boilerplate code.Configure project name and package details.When setting up the spring boot application, the spring initializer comes in handy. The mail id should be sent to the server as an optional query parameter. When the document is ready, it should be sent to the user over email.Document generation should happen behind the screen and the front end should receive an immediate acknowledgment.The front end calls our backend endpoint with the input parameters and template ID.This is the requirement I have taken for demonstration and I kept them simple enough. I'm going to write a Spring Boot application. This is part II of my article " Template-Based PDF Document Generation in JavaScript." This made me think, why not write an article on the Template-Based PDF Document Generation in Java? And they have mostly done in java spring boot application. Eclipse.In my previous article, I wrote about how we can seamlessly generate template-based documents in our JavaScript application using EDocGen.Īs a Java developer, I have worked on creating backend applications for e-commerce and healthcare enterprises where the requirement for document generation is vast. The unit tests can be executed from Maven, Gradle, or individually in an IDE e.g. The org.json package can be built from the command line, Maven, and Gradle. For more information, please read the FAQ. If you would like to contribute to this projectįor more information on contributions, please see CONTRIBUTING.mdīug fixes, code improvements, and unit test coverage changes are welcome! Because this project is currently in the maintenance phase, the kinds of changes that can be accepted are limited. The package can also convert between JSON and XML, HTTP headers, Cookies, and CDL. The files in this package implement JSON encoders and decoders. Designed and tested to use on Java versions 1.8 - 21.Fast execution and low memory footprint.Easy to build, use, and include in other projects.The JSON-Java package is a reference implementation that demonstrates how to parse JSON documents into Java objects and how to generate new JSON documents from the Java classes. JSON is a light-weight language-independent data interchange format. Image credit: Ismael Pérez Ortiz JSON in Java Ĭlick here if you just want the latest release jar file.
