Creating Spring Boot Microservices

Course details

If you’re looking for a practical introduction on creating Spring Boot microservices, this course was designed just for you. Join instructor and software developer Mary Ellen Bowman as she provides a skills-based, intermediate-level overview on how to create microservices using the power of Spring Boot 3. Along the way, discover several other related technologies and frameworks such as Spring Data, Spring Data REST, Spring MVC, JUnit, Mockito, SpringBootTest, Docker, MongoDB, Spring Security, and Spring Cloud.
