So ein Thema gab es noch nicht, zum mindestens ich habe es nicht gefunden.

Ich verwende für meinen Spring Boot 3 Projekt als View eine Thymeleaf Template und dort habe ich einen Form-Tag:
HTML: 
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <title>Profile Details</title>
</head>
<body>
    <h1>Profile Details</h1>
    
    <form th:action="@{/forum-homepage/}" method="post">
        <label for="id">ID:</label>
        <input type="text" id="id" name="id" />
        <button type="submit">Search</button>
    </form>
    
    
    <!--                  E R R O R M E S S A G E                -->
    <div th:if="${error}" style="color: red;">
        <p th:text="${error}"></p>
    </div>
    
    
    <!--                      P R O F I L E                     -->
    <div th:if="${profile != null}">
        <ul>
            <li>Login: <span th:text="${profile.login}"></span></li>
            <li>First Name: <span th:text="${profile.firstName}"></span></li>
            <li>Last Name: <span th:text="${profile.lastName}"></span></li>
            <li>Birthdate: <span th:text="${profile.birthdate}"></span></li>
        </ul>
    
    </div>
zu dem habe ich eine @PostMapper Methode in meinem Controller:

Java: 
//Profile Simple
    @PostMapping("/forum-homepage/")
    public String forum_pageWithValue(Model model, @RequestParam("id") String idStr){
        //id Identification
          String numericPattern = "^[0-9]+$";

        if (!idStr.matches(numericPattern)) {
            model.addAttribute("error", "Invalid Id format. Please enter a valid numeric Id.");
            return "forum-homepage";
        }
        try {
                Long id = Long.parseLong(idStr);
                if(id <= 0) {
                    model.addAttribute("error", "The Id must be greater then 0.Please enter a valid numeric Id.");
                return "forum-homepage";
                }
                Profile profile = profileService.selectById(id);
                
                if(profile == null) {
                    model.addAttribute("error", "No such Profile found");
                }else {
                    model.addAttribute("profile", profile);
                }
        }catch(TemplateInputException e) {
            model.addAttribute("error", "Invalid Id format. Please enter a valid numeric Id.");
        }catch( NumberFormatException e) {
            model.addAttribute("error", "Invalid Id format. Please enter a valid numeric Id.");
        }catch(Exception e) {
            model.addAttribute("error", "An error occurred while fetching the profile. Please try again.");
        }
        
        return "forum-homepage";
    }

Alles funktioniert bei der Angabe so weit so gut. Zum Beispiel wenn du die: 0 eingibst, wird darauf reagiert und gesagt, so einen User/Profile gibt es nicht, dasselbe passiert auch bei den Strings, wie "jdihf" oder sonst noch was. Doch wenn du die Zahl 22 eingibst wird sofort ein EntityNotFoundException geworfen, weil ich in der Datenbank maximal nur 21 Profiles habe. Ich habe versucht diesen Fehler mit NumberFormatException oder auch TemplateInputException.
Dazu will ich noch sagen, am anfang wurden auch die Zahlen, die größer sind als 21 eingefangen und richtig ausgegeben, danach habe ich in meinen Tags ir-etwas entfernt und seit dem bekomme ich folgende Fehlermeldung:

Oneixee5 hat gesagt.:
Muss das nicht @RequestBody lauten bei Post-Requests ...
Java: 
@PostMapping("/forum-homepage/")
    public String forum_pageWithValue(Model model, @RequestParam("id") String idStr) {

PS: für Thymeleaf noch anders: https://spring.io/guides/gs/handling-form-submission
Zum Vergrößern anklicken....
Also es funktioniert genau so gut mit @PathVariable("id"), oder bringt der RequestParam eine Lösung für das Problem, das ich oben beschrieben habe?

Was das Thymeleaf betrifft, danke ich dir, könnte damit einige weitere Verständnis Fragen lösen.

Danke Euch, ich habe das Problem gelöst bekommen. Ein Review von zweiter Meinung hat mich auf das Problem hingewiesen.
Für den Fall, wenn ein Profile aufgerufen wird, der nicht existiert, hatte ich in der Wirklichkeit keine Vorkehrung getroffen.
Ich hatte zwar in meiner PostMapping Methode das Profile Objekt geprüft, ob es null ist, aber das übergebende Objekt an das PostMapping ist niemals null. Es hat einfach keinen Inhalt:

Java: 
//Im Controller

//Profile Simple
    @PostMapping("/forum-homepage/")
    public String forum_pageWithValue(...){
    
                ...
                Profile profile = profileService.selectById(id);
                
                if(profile == null) {
                    model.addAttribute("error", "No such Profile found");
                }else {
                    model.addAttribute("profile", profile);
                }
.                ...
    }
------------------------------------------------------
von diesem Fall zu diesem gewechselt:

Code: 
//Im Controller

//Profile Simple
    @PostMapping("/forum-homepage/")
    public String forum_pageWithValue(...){
    
                ...
                Profile profile = profileService.selectById(id);
                
                if(profile.getLogin() == null) {
                    model.addAttribute("error", "No such Profile found");
                }else {
                    model.addAttribute("profile", profile);
                }
.                ...
    }

Dann stimmt alles
