This tutorial explains how we can use DataSource defined in tomcat container as a JNDI resource to get database connection and perform different operations. This is the preferred way for getting database connections in a spring web application because the container takes care of managing database resources. Spring @Bean Spring @Bean Annotation is applied on a method to specify that it returns a bean to be managed by Spring context.

In this course, instructor Dan Vega, a popular Spring framework instructor on Udemy will teach you how to develop a web application using Spring Boot. It’s also now becoming a standard way to use the Spring framework in many companies and they are looking for Java developers with some Spring Boot experience. This tutorial is written for readers who have a prior experience of Java, Spring, Maven, and Gradle.

Spring Boot Testing

Now, let’s dive into learning about Spring Boot Actuator, where you’ll learn everything about non-functional requirements, and how to use this technology by simply adding it to your classpath. We’ll start learning how to configure Web Authentication, Spring Boot Lessons from basic auth, to using an HTML form. In this demo you’ll see how to expose resources with Restful URLs, you’ll map request and response bodies using HTTP Message Converters, and implement the server-side REST endpoints.

It also didn’t give us great visibility of whether a unit, unit integration or component test covered the lines, just that it was covered, so we still needed to dig through the code to understand. In the future we could consider looking at mutation testing as a means of discovering gaps in our tests’ implementation, too. With this basis done, we could start work on the project, as we had a good set of tools to support changes to the service. In that year since, the team I’d been on had finished the PSD2 delivery and we’d started getting breathing room to look at improving our services.

• Something we did – but not quite enough – while working on this was to share with others what we’ve learned.
• You will also learn to develop a modern Java web application using Spring Boot, a RESTful web service, and integrating a JavaScript-based UI. Most importantly, the Spring MVC Integration.
• In our case, we’d probably have learned that no, it wasn’t enough.
• You will learn about key Microservice and cloud concepts like client-side load balancing using Ribbon, Dynamic Scaling using Eureka Naming Server, Fault tolerance for microservices with Hystrix, etc.
• We will make sure this is the case by checking the required box.
• Spring is one of the most widely used Java EE frameworks and Hibernate is the best ORM framework in the market.
