Enterprise Java

Performance is a topic of increasing importance for anyone who uses applications to support their business activities. Today performance engineers and architects as well as operations people have to ensure that complex application landscapes work seamlessly and problems are resolved fast and with minimal effort.

While containers, microservices, and distributed systems dominate discussions in the tech world, the majority of applications in use today still run monolithic architectures that follow traditional development processes. This practical book helps developers examine long-established Java-based models and demonstrates how to bring these monolithic applications successfully into the future.

This book focuses more on the details of a hands-on approach to Web Service programming than its specifications; however, in order to help readers grasp the concept more easily, we provide a brief introduction to Web Service, SOAP, and WSDL in the first three chapters. Many details of the specifications are intentionally glossed over, however, so that the content remains manageable.

This is a summary of some of the most important questions concerning the Spring Framework, that you may be asked to answer in an interview or in an interview test procedure!

The Spring Framework is an open-source application framework and inversion of control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE platform. Although the framework does not impose any specific programming model, it has become popular in the Java community as an alternative to, replacement for, or even addition to the Enterprise JavaBeans (EJB) model.

Spring 5 and its ecosystem can be used to build robust architectures effectively. Software architecture is the underlying piece that helps us accomplish our business goals whilst supporting the features that a product demands.
