In this chapter, we discussed the cross-cutting concerns, why those are important, and how the code becomes unnecessarily complex when it is introduced in the application. We discussed AOP to solve the problem of code duplication while using cross-cutting concerns, and how to make it simple using aspects. We discovered many terminologies, such as Advice, pointcut, weaving, and introduction, and how to use them in depth. We also did an integration of logging mechanism as a cross-cutting concern using aspect in the application, using both the schema-based and annotation-based approach. We also discussed introduction advice, which facilitates the addition of new functionalities without changing the original code. We opened the chapter by discussing transaction management, which is another very important cross-cutting concern. However, we haven't talked about it here; the next chapter will be completely dedicated to transaction management.

Overview of this book
<p>Spring is the most widely used framework for Java programming and with its latest update to 5.0, the framework is undergoing massive changes. Built to work with both Java 8 and Java 9, Spring 5.0 promises to simplify the way developers write code, while still being able to create robust, enterprise applications.</p>
<p>If you want to learn how to get around the Spring framework and use it to build your own amazing applications, then this book is for you.</p>
<p>Beginning with an introduction to Spring and setting up the environment, the book will teach you in detail about the Bean life cycle and help you discover the power of wiring for dependency injection. Gradually, you will learn the core elements of Aspect-Oriented Programming and how to work with Spring MVC and then understand how to link to the database and persist data configuring ORM, using Hibernate.</p>
<p>You will then learn how to secure and test your applications using the Spring-test and Spring-Security modules. At the end, you will enhance your development skills by getting to grips with the integration of RESTful APIs, building microservices, and doing reactive programming using Spring, as well as messaging with WebSocket and STOMP.</p>
