Hands-On Microservices with Kotlin

Using simple objects

For example, let's create a simple class named SimpleObject, with this structure:

package com.microservices.chapter3class SimpleObject {  public val name = "hello"  private val place = "world"}

Now, let's create a new controller for testing this, we will name it JsonExamplesController; it will be a RestController that has one GetMapping:

package com.microservices.chapter3import org.springframework.web.bind.annotation.GetMappingimport org.springframework.web.bind.annotation.RestController@RestControllerclass JsonExamplesController {  @GetMapping(value = "/json")  fun getJson() = SimpleObject()}

Then, if we execute our microservice and do a request to this URL http://localhost:8080/json, we should get:

{"name":"hello"}
