“Circular view path” in a simple Spring Boot project with a Controller

Question

I have a simple Spring Boot project with this Gradle build file:

apply plugin: \'java\'
apply plugin: \'eclipse\'
apply plugin: \'spring-boot\'
apply plugin: \'w         


        

Answer 1

You can use @RestController in your Spring Boot project instead of @Controller annotation. In this way you don't have to use @ResponseBody annotation in your method even if your method doesn't return any value.

Answer 2

Adding @ResponseBody in your controller will solve this problem as below:

 public @ResponseBody void test() {
    }

Answer 3

You've annotated the controller method as producing JSON, but it returns void. You probably want to annotate the method with @ResponseBody and change its return type to allow you to return an object representation of the JSON that you want to include in the response
