Spring Boot microservices are capable of a plethora of functions, but like all web applications, these must be secured. In this course, you'll start by building Spring Boot microservices to configure your application to send emails. Then, you'll use interceptors to pre-process requests and responses to and from your application and integrate it with the Twilio platform to send text messages and make phone calls. Next, you'll learn to integrate with external services, such as JavaMailSender and the Twilio platform, within your Spring Boot application. Lastly, you'll learn how to secure your application using in-memory users and users stored in a database using Spring Security.

Spring Boot has some exciting features to offer. It's not difficult to run asynchronous tasks using Spring Boot; all it needs are a few annotations to set up. In this course, you'll learn how to configure your applications to run scheduled tasks at a fixed rate and fixed delay. You'll also set up forms using the Thymeleaf template engine and perform built-in validation on the form fields. Next, you'll learn how to configure handler mappings in Spring MVC for request paths, extract request parameters and path variables, and run asynchronous and scheduled operations in Spring Boot. Finally, you'll learn how to perform validation of user-specified form inputs.

Building a RESTful API service to perform create, read, update, and delete (CRUD) operations is an integral part of building microservices with Spring Boot. In this course, you'll learn how to build a RESTful API service to perform CRUD operations. You'll use Advanced REST Client to test your API service, and wire up a MySQL database using JPA, Spring Data, and Hibernate. You'll then add a front end to your application using the Thymeleaf template engine. Finally, you'll build RESTful microservices in Spring Boot, integrate with a relational database to store your data, set up a front end for your application, and add caching for common requests.

Setting up a new Spring Boot application is simple, and with the use of starter templates, the parent POM, and auto-configurations, running a Spring Boot application is also easy. In this course, you'll explore the Spring Boot framework and features of Spring Boot and the basic design principle of inversion of control achieved in Spring using dependency injection. Next, you'll learn how to run an embedded web server in a simple Spring Boot application, set up a new Spring Boot project using the Spring Initializr and Spring Tools Suite, and configure properties for your Spring Boot application.
