I'm having this error with my spring boot application
There was an unexpected error (type=Method Not Allowed, status=405). Resolved [org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'POST' not supported]
I've read about it here: https://www.baeldung.com/spring-request-method-not-supported-405
but I can't still figure this one out since I'm new to spring and java
Here what I can do
- I can navigate to any page without problem
- I can add a new evaluation
- I can delete an evaluation
Here what I'm trying to do
After creating an evaluation I want to edit it I can navigate to the update page and the form is filled as expected I can change the value but when I press submit I get the error message and for some reason the URL is this one http://localhost:8080/modifier/modifierEvaluation
The method from the HTTP header is POST as expected and I can see the value of the change in the payload also
Here is my code
The controller
@Controller
public class ModifierController {
@Autowired
EvaluationDataContext context;
@GetMapping("/modifier/{id}")
public ModelAndView modifier(@PathVariable("id") int id, Model model) {
Evaluation evaluation = EvaluationDataContext.Rechercher(id);
// Create the option for the select tags
Map<String, String> noteItems = new LinkedHashMap<String, String>();
noteItems.put("Tres bien", "Très bien");
noteItems.put("Bien", "Bien");
noteItems.put("Moyen", "Moyen");
noteItems.put("Mediocre", "Médiocre");
model.addAttribute("noteItems", noteItems);
model.addAttribute("evaluation", evaluation);
return new ModelAndView("modifier", "evaluation", evaluation);
}
@PutMapping("/modifierEvaluation/{id}")
public String modifierPost(@ModelAttribute("evaluation") Evaluation evaluation) {
context.Modifier(evaluation);
return "redirect:/listeEvaluation";
}
}

CodePudding user response：
Because you use @PutMapping it is for PUT. You need @PostMapping https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/web/bind/annotation/PostMapping.html
@PostMapping("/modifierEvaluation/{id}")
public String modifierPost(@ModelAttribute("evaluation") Evaluation evaluation) {
context.Modifier(evaluation);
return "redirect:/listeEvaluation";
}
Try add to form tag method = "POST"
<form:form action="modifierEvaluation" modelAttribute="evaluation" method = "POST">
CodePudding user response：
Hey guys i finally found the answers the error was a basic one my the route of my action in my form was this one
modifierEvaluation/${id}
When it should have been this one
/modifierEvaluation/${id}
Which was causing the URL to be appended at the end instead of replaced, that why I had the following URL
http://localhost:8080/modifier/modifierEvaluation
