JnRouvignac/AutoRefactor

I have a legacy springMvc project and i want to refactor all the controllers to return ResponseEntity<T> object rather then returning Model object which is returned by default.

I am looking for a way to map functions in Map class to ResponseEntity<T> class .

I have seen people recommend to use Regular expression as a solution to refactor all the methods.

I need to know your opinion about implementing Regex as solution in terms of advantages / drawbacks for using regex in this scenario.

In addition it would be helpful if you can suggest other solutions.

please take a look at the attached code for more details.

return Model object to the view

@GetMapping("/getData")
    public String getData(Model model) {

        model.addAttribute("message", "springMvc");

        return "viewPage";
    }

return ResponseEntity object as a json format

@GetMapping("/getData")
    public ResponseEntity<Map<String,String>>  getData() {

        Map<String,String> map = new  HashMap<>();
        map.put("message", "springMvc");

        return  new ResponseEntity.Ok().body(map);
    }
