Spring Boot example for @NotEmpty annotaion

Question

I am developing spring boot application which has freemarker for UI. I want to use @NotEmpty annotation for radio button. eg "input type="radio"

I can see examples on internet but they are with form tag(spring tag).

Can someone give me example for above without form tag.

Answer 1

You can use

<@spring.formRadioButtons "x.y"/>
<@spring.showErrors "<br>"/> 

to display the validation messages.

Have a look at this tutorial:
