I all, i get the following error from a Spring boot application. This is the code of my Controller class (other services in the controller works without problems):
@GetMapping(value="/productListConResponseEntity", produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<?> productListConResponseEntity(HttpServletRequest req) {
SampleMessage status = new SampleMessage();
ProductDTOOut productDTOOut = null;
try {
productDTOOut = productService.productListConResponseEntity();
}catch(Exception e) {
status.setStatus(Constant.ko);
status.setMessage(e.getMessage() != null?e.getMessage():e.toString());
}
**-->> ProductController.java:108** new ResponseEntity<ProductDTOOut>(productDTOOut, productDTOOut.getStatus().getHttpStatus(req));
}
