Testing Client Applications You can use client-side tests to test code that internally uses the RestTemplate. The idea is to declare expected requests and to provide “stub” responses so that you can focus following example shows how to do so: Java RestTemplate restTemplate = new RestTemplate(); MockRestServiceServer mockServer = MockRestServiceServer.bindTo(restTemplate).build(); mockServer.expect(requestTo("/greeting")) Test code that uses the above RestTemplate ... mockServer.verify(); Kotlin val restTemplate = RestTemplate() val mockServer = MockRestServiceServer.bindTo(restTemplate).build() mockServer.expect(re

REST Endpoints The Spring Framework provides two choices for making calls to REST endpoints: • RestTemplate: The original Spring REST client with a synchronous, template method API. • WebClient: a non-blocking supports both synchronous and asynchronous as well as streaming scenarios.  As of 5.0 the RestTemplate is in maintenance mode, with only minor requests for changes and bugs to be accepted going forward
