RequestParam / User Not Found

Hello again guys, I'd like to render my data user on a template with the GET method. I made sure my page was created and my datas are persisted in my db. I tried to render my data through the email user as it's shown below and I want my URL to be like this : http://localhost:8080/[email protected] ( which works perfectly if I write this in my browser bar ) but when I want to access to my profile it return me a USer nto found, because Spring boot sees it as null

 @GetMapping("/profile")
        public String getUserProfile(Model model, @RequestParam(required = false) String email){
            
            AppUser user = repo.findByEmail(email);
            System.out.println("the email is :" + email);
            if(user != null){
                model.addAttribute("user", user);
            }else{
                model.addAttribute("error", "User not found");
            }

            return "profile";
        }

 @GetMapping("/profile")
        public String getUserProfile(Model model, @RequestParam(required = false) String email){
            
            AppUser user = repo.findByEmail(email);
            System.out.println("the email is :" + email);
            if(user != null){
                model.addAttribute("user", user);
            }else{
                model.addAttribute("error", "User not found");
            }

            return "profile";
        }

Does it work if you use @RequestParam(required = false, name = "email") ? The the javac-compiler miss the -parameter flag. See https://docs.oracle.com/en/java/javase/17/docs/specs/man/javac.html

Unfortunately, I have tried this one, but it didn't work, it's seen as null

Peter Rader•4mo ago

What have you tried? The modification of the Annotation or the -parameter flag?

SungOP•4mo ago

The @RequestParam(required = false, name = "email") . I'm currently looking for an article about retrieving my query parameter but I still didn't find the solution. But as I said, oddly I can get my mail if I write the whole query in my URL http://localhost:8080/[email protected] like this, then it returns the data I want

Peter Rader•4mo ago

But you can not get the email when you access your profile, right?

SungOP•4mo ago

Well actually, I didn't build anything yet in my profile page but when I write the whole URL, it returns me the name but when I click to access to the profile page it doesn't

I do not get it. Do you have a profile-page or not? Hm, there might be a corner-case where https://localhost:8080/[email protected] might be parsed as Domain: https://test.com using the username localhost and the password 8080/profile?email=test. But this might not explain an request to the server without email-parameter Could you try to urlencode the @?

SungOP•4mo ago

I have it but when I click on the profile page it returns me a user not found because the param query is null Wait we need to urlencode the special characters ? Wait no on this one I think you're wrong because if it wasn't encoded, I couldn't even get a status 200 from my URL as I showed you above
