Question

I am creating a Rest based web service using spring boot,while deploying in tomcat am not getting error.But when i'm trying to hit the RestController's method which is annotated with #RequestMapping and trying to print a string in the browser.
Am getting the error:
type Exception report
message Circular view path [error]: would dispatch back to the current
handler URL [/services-0.0.1-SNAPSHOT/error] again. Check your
ViewResolver setup! (Hint: This may be the result of an unspecified
view, due to default view name generation.)
description The server encountered an internal error that prevented it from fulfilling this request.

Check whether your controller class marked with #RestController. If not, and you just annotated it with #Controller, you have to change the #Controller annotation to #RestController. You can have same result by adding #ResponseBody to your controller class or every controller mothods that is used for restful API.
