Overview of this book

The demand for modern and high performing web enterprise applications is growing rapidly. No more is a basic HTML frontend enough to meet customer demands. This book will be your one-stop guide to build outstanding enterprise web applications with Java EE and Angular. It will teach you how to harness the power of Java EE to build sturdy backends while applying Angular on the frontend. Your journey to building modern web enterprise applications starts here! The book starts with a brief introduction to the fundamentals of Java EE and all the new APIs offered in the latest release. Armed with the knowledge of Java EE 8, you will go over what it's like to build an end-to-end application, configure database connection for JPA, and build scalable microservices using RESTful APIs running in Docker containers. Taking advantage of the Payara Micro capabilities, you will build an Issue Management System, which will have various features exposed as services using the Java EE backend. With a detailed coverage of Angular fundamentals, the book will expand the Issue Management System by building a modern single page application frontend. Moving forward, you will learn to fit both the pieces together, that is, the frontend Angular application with the backend Java EE microservices. As each unit in a microservice promotes high cohesion, you will learn different ways in which independent units can be tested efficiently. Finishing off with concepts on securing your enterprise applications, this book is a handson guide for building modern web applications.

Java EE Becomes JSON Friendly

JSON enhancements in Java EE allow for working with JSON in a much simpler way than before. The addition of JSON processing and binding has turned it into a first-class citizen of Java EE. Use APIs to serialize and deserialize Java objects, to and from JSON documents. JSON-B does for JSON, what JAXB did for XML. No longer do you have to rely upon third-party libraries to work with JSON. Most features will work out of the box, with sensible defaults.

We will cover the following topics in this chapter:

  • REST prefers JSON
  • JSON first-class citizen
  • No more third-party libraries
  • JSON processing:
    • JSON-P 1.1
    • JSON pointer and JSON patch
    • JSON merge patch
    • JSON collectors
  • JSON binding:
    • Similar to JAXB with default mappings
    • Standardize current solutions (Jackson, Gson, and so on)
    • Mapping between classes and JSON
    • Customisation APIs
  • A few tips in practice
  • ...
