Through this book, users will learn to master the concepts of AOP by developing several real-life AOP-based applications with the Spring Framework, and implementing the basic components of Spring AOP: Advice, Joinpoint, Pointcut, and Advisor. By implementing an interface that manages invocations, developers will learn to set up a dynamic proxy with JDK. Along with this, they will be able to structure the behavior of the pattern proxy design pattern by applying the crosscutting concerns of security, logging, and transactionality to specific Joinpoints. They will also be able to remove the implementation compromises in applications by learning about the AOP that is enabled by the Spring Framework and Inversion of Control (IoC).
