Overview of this book

The Spring framework has been the go-to framework for Java developers for quite some time. It enhances modularity, provides more readable code, and enables the developer to focus on developing the application while the underlying framework takes care of transaction APIs, remote APIs, JMX APIs, and JMS APIs. The upcoming version of the Spring Framework has a lot to offer, above and beyond the platform upgrade to Java 9, and this book will show you all you need to know to overcome common to advanced problems you might face. Each recipe will showcase some old and new issues and solutions, right from configuring Spring 5.0 container to testing its components. Most importantly, the book will highlight concurrent processes, asynchronous MVC and reactive programming using Reactor Core APIs. Aside from the core components, this book will also include integration of third-party technologies that are mostly needed in building enterprise applications. By the end of the book, the reader will not only be well versed with the essential concepts of Spring, but will also have mastered its latest features in a solution-oriented manner.

Monitoring services and request handlers


Aspects has some trade-offs when used to intercept DAO transactions. Most often we use aspects to monitor services and @Controller transactions. This recipe will show us the easiest way to monitor service and request transactions using transaction management.

Getting started

Open ch05 and add an @Aspect that will monitor EmployeeController's deleteRecord() request handler and EmployeeServiceImpl's readEmployee() using a custom annotation.

How to do it...

After the DAO layer, let us monitor all service and @Controller request transactions by following these steps:

  1. This is the first recipe that will showcase the use of custom transaction management annotations in formulating Pointcuts for advices. Using Reflection APIs, create the following method-level annotation inside the org.packt.aop.transaction.annotation package:
@Retention(RetentionPolicy.RUNTIME) 
@Target(ElementType.METHOD) 
public @interface MonitorService {  } 
  1. To make @MonitorTransaction transaction...
