Enterprise Application Development with Ext JS and Spring

By: Gerald Gierer

Overview of this book

Spring and Ext JS are cutting edge frameworks that allow us to build high performance web applications for modern devices, that are now consuming data at a faster rate than ever before. It is the appropriate time for you to understand how to best leverage these technologies when architecting, designing, and developing large scale web development projects. This practical guide condenses an approach to web development that was gained from real world projects, and outlines a simple, practical approach to developing high performance, and enterprise grade web applications. Starting with configuring Java, NetBeans, and MySQL to prepare your development environment, you will then learn how to connect your NetBeans IDE to the MySQL database server. We will then explore the Task Time Tracker (3T) project database structure and populate these tables with test data. Following on from this, we will examine core JPA concepts after reverse engineering the domain layer with NetBeans. Leveraging the Data Access Object design pattern, you will learn how to build the Java DAO implementation layer assisted by generics in base classes, followed by a Data Transfer Object enabled service layer to encapsulate the business logic of your 3T application. The final chapters that focus on Java explore how to implement the request handling layer using Spring annotated controllers, and deploy the 3T application to the GlassFish server. We will then configure the Ext JS 4 development environment and introduce key Ext JS 4 concepts, including MVC and practical design conventions. Covering a variety of important Ext JS 4 strategies and concepts, you will be fully-equipped to implement a variety of different user interfaces using the Ext JS MVC design pattern. Your journey ends by exploring the production build and deployment process using Maven, Sencha Cmd and GlassFish.

Enterprise options for the 3T database


The table and column definitions provided previously are the simplest required for our 3T project. There are, however, several potential options that could be added to enhance the structure for enterprise use.

Password encryption

Enterprise applications would require that the password field be encrypted for security purposes using a unidirectional algorithm. Passwords should never be stored in plain text, and it should never be possible to view the password in the database (as we can currently do). It is beyond the scope of this book to cover password security strategies, but a very good explanation of the core principles can be found at http://www.jasypt.org/howtoencryptuserpasswords.html.

MySQL provides a number of password encryption functions that could be used for this purpose. We suggest you browse the documentation at https://dev.mysql.com/doc/refman/5.7/en/encryption-functions.html to understand the different options available.
