I am trying to recreate the functionality of Spring Data REST controller in a custom REST controller class so that I can get HAL formatted JSON and be able to use projections. Now I was able to do it in Spring Boot 1.5.17 using the following code.
@RequestMapping(method = GET, value = "students/fetchProfile")
public @ResponseBody
ResponseEntity<?> fetchStduentProfile(@RequestParam(required = true) String idNumber,
PersistentEntityResourceAssembler resourceAssembler) {
Student student = studentHandler.fetchStudent(idNumber);
if (student != null) {
return ResponseEntity.ok(resourceAssembler.toResource(student));
} else {
return new ResponseEntity<>(null, HttpStatus.NOT_FOUND);
}
}
But once I upgraded to Spring Boot 2.3.8 I am getting an HttpMessageNotWritableException
265.79 kB (204.8 kB loaded)
org.springframework.http.converter.HttpMessageNotWritableException: Could not write JSON: Infinite recursion (StackOverflowError); nested exception is com.fasterxml.jackson.databind.JsonMappingException: Infinite recursion (StackOverflowError) (through reference chain: org.springframework.data.jpa.mapping.JpaPersistentPropertyImpl["owner"]->org.springframework.data.jpa.mapping.JpaPersistentEntityImpl["idProperty"]->org.springframework.data.jpa.mapping.JpaPersistentPropertyImpl["owner"]->org.springframework.data.jpa.mapping.JpaPersistentEntityImpl["idProperty"]-

Now I know there have been major changes in Spring HATEOAS but I am not sure how to migrate this controller to the new HATEOS classes. I even tried resourceAssembler.toModel() and it produced the same exception.
So how do I make this controller work with the new version of Spring HATEOAS so I can get HAL formatted JSON and also use projection parameters?
