Spring 5.0 Projects

By: Nilang Patel

Overview of this book

Spring makes it easy to create RESTful applications, merge with social services, communicate with modern databases, secure your system, and make your code modular and easy to test. With the arrival of Spring Boot, developers can really focus on the code and deliver great value, with minimal contour. This book will show you how to build various projects in Spring 5.0, using its features and third party tools. We'll start by creating a web application using Spring MVC, Spring Data, the World Bank API for some statistics on different countries, and MySQL database. Moving ahead, you'll build a RESTful web services application using Spring WebFlux framework. You'll be then taken through creating a Spring Boot-based simple blog management system, which uses Elasticsearch as the data store. Then, you'll use Spring Security with the LDAP libraries for authenticating users and create a central authentication and authorization server using OAuth 2 protocol. Further, you'll understand how to create Spring Boot-based monolithic application using JHipster. Toward the end, we'll create an online book store with microservice architecture using Spring Cloud and Net?ix OSS components, and a task management system using Spring and Kotlin. By the end of the book, you'll be able to create coherent and ?exible real-time web applications using Spring Framework.

Building a UI with the Mustache template

The Mustache is a web template available for many languages, like JavaScript, Ruby, PHP, Python, Perl, Android, C++, Java, and so on, with a language-specific implementation. In our Blogpress application, we will use Mustache for JavaScript, so we need to include Mustache.js in the Blogpress application. Let's first understand the use case where Mustache.js is appropriate.

Quite often, to show dynamic values in HTML, we mix the data with HTML fragments and then update the DOM markup to show the final output. The following is the sample example for this approach:

$("#addAddress").live('click', function(){;
       var oldAddress = "";//Assume that oldAddress value supplied from server side.
       var newContent = "<div id='group2' class='accordion-group'>" +
                        "<input type='text' id='address' class='textbox-input'"+ oldAddress +"/>"                            + "</div>";
       $("#accordion1").html(newContent...
