Developing Java Applications with Spring and Spring Boot

Overview of this book

Spring Framework has become the most popular framework for Java development. It not only simplifies software development but also improves developer productivity. This book covers effective ways to develop robust applications in Java using Spring. The course is up made of three modules, each one having a take-away relating to building end-to-end java applications. The first module takes the approach of learning Spring frameworks by building applications.You will learn to build APIs and integrate them with popular fraemworks suh as AngularJS, Spring WebFlux, and Spring Data. You will also learn to build microservices using Spring's support for Kotlin. You will learn about the Reactive paradigm in the Spring architecture using Project Reactor. In the second module, after getting hands-on with Spring, you will learn about the most popular tool in the Spring ecosystem-Spring Boot. You will learn to build applications with Spring Boot, bundle them, and deploy them on the cloud. After learning to build applications with Spring Boot, you will be able to use various tests that are an important part of application development. We also cover the important developer tools such as AMQP messaging, websockets, security, and more. This will give you a good functional understanding of scalable development in the Spring ecosystem with Spring Boot. In the third and final module, you will tackle the most important challenges in Java application development with Spring Boot using practical recipes. Including recipes for testing, deployment, monitoring, and securing your applications. This module will also address the functional and technical requirements for building enterprise applications. By the end of the course you will be comfortable with using Spring and Spring Boot to develop Java applications and will have mastered the intricacies of production-grade applications.

Monitoring Spring Boot via JMX

In today's day and age, the RESTful HTTP JSON services are a de facto way of accessing data, but this is not the only way to do so. Another fairly popular and common way of managing systems in real time is via JMX. The good news is that Spring Boot already comes with the same level of support to expose the management endpoints over JMX as it does over HTTP. Actually, these are exactly the same endpoints; they are just wrapped around the MBean container.

In this recipe, we will take a look at how to retrieve the same information via JMX as we did via HTTP as well as how to expose some MBeans, which are provided by third-party libraries through HTTP using the Jolokia JMX library.

Getting ready

If you haven't done so already for the previous recipe, then add the Jolokia JMX library to our compile("org.jolokia:jolokia-core:+") build dependency and add the management.jolokia.enabled=true property to, as we will need them to expose MBeans via...
