It is important to secure the microservices. This will be more significant when there are many microservices communicating with each other. Each service needs to be secured, but at the same time, security shouldn't surface as an overhead. In this section, we will learn some basic measures to secure microservices.

Note

The full source code of this example is available as the chapter3.security project in the code files of this book under the following Git repository: https://github.com/rajeshrv/Spring5Microservice

Perform the following steps for building this example:

• Create a new Spring Starter project, and select Web and Security (under core)
• Name the project as chapter3.security
• Copy rest endpoint from chapter3.bootrest
