Spring Boot Thymeleaf Ajax Call

I try to call a Spring Boot controller from a Ajax Request:

 $('#female').click(function(){
   $('#analysisTable').DataTable( {
     "ajax": '/analyse/female'
   });
 });

The Idea behind this is to load a list into a js datatable. The controller looks like:

@GetMapping("/analyse/female")
public List<GenderAnalysis> analysisByFemale(final Model model) {
    final List<GenderAnalysis> result = analyseDao.getAnalysisByGender(AnalyseDAO.Gender.Female);
    return result;
}

The controller works fine. But i get an Thymeleaf Template error. Every response will be handled through a ThymeleafLayoutInterceptor and load "normal" (not ajax) requests into a template.

The erorr is the following:

org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "class path resource [templates/analyse/female.html]")

I know that there is not a female.html resource and i even won't have one. Just serve the raw List to ajax call.

I'm not sure how to work with Spring Boot+Thymeleaf+Ajax even with templates. Could it be a handling problem with the interceptor? What can i do? Anybody able to help?

If you want to return JSON rather than a Thymeleaf template, you should either:

1) Declare the controller as a @RestController rather than just a @Controller. This will affect all @GetMapping, @PostMapping and @RequestMapping annotations on your controller class.

or

2) Declare the method as a @ResponseBody in addition to the @GetMapping.

@GetMapping("/analyse/female")
@ResponseBody
public List<GenderAnalysis> analysisByFemale() {
    return analyseDao.getAnalysisByGender(AnalyseDAO.Gender.Female);
}
