We can use it directly. First, create a spring boot hello-world   gradle project using reference: https://beginnersword.blogspot.com/2020/07/getting-started-with-spring-boot.html Implementation: Add the below gradle dependencies in the build.gradle file. Let’s create a TestCacheController in the controller package and create an endpoint named it as /testCaching . Now create a model class Test and create a variable named username, message then generate getter and setter for them. Let’s now create a service class with the name TestCacheService a...
