I want edit entity with validating by hibernate-validator, but when calling the patch method, an error is thrown: post method not supported
. How to make @PatchMapping
work correctly? I am a beginner developer, help me please.
Controller:
@GetMapping("/edit/{id}") //for admin & developer
public String edit(@PathVariable("id") Long id, Model model, @AuthenticationPrincipal UserDetails user){
final ProjectDTO project = this.projectService.getDTOById(id);
model.addAttribute("project",project);
model.addAttribute("currentUser", this.userService.findUserByNickname(user.getUsername()));
return "project/edit";
}
@PatchMapping("/update")
public String update(@RequestParam("project") @Valid Project project, BindingResult bindingResult,
Model model, @AuthenticationPrincipal UserDetails user,
@RequestParam("files") MultipartFile[] files) throws IOException{
final User author = userService.findUserByNickname(user.getUsername());
model.addAttribute("currentUser", author);
model.addAttribute("files", files);
if(bindingResult.hasErrors()){
return "project/edit";
}
List<FileInfo> infoList = this.projectService.upload(Arrays.asList(files));
project.setFileList(infoList);
project.setPreviewId(infoList.get(0).getId());
this.projectService.update(project);
return "redirect:/portfolio";
}
Service:
@Transactional
public void update(Project project){
this.projectRepository.update(project.getId(),
project.getTitle(),
project.getDescription());
}
Repository:
@Transactional
@Modifying
@Query(value = "UPDATE Project p SET p.title = :title, p.description = :description WHERE p.id = :id")
void update(@Param("id") Long id,
@Param("title") String title,
@Param("description") String description);
html form:
<form th:action="@{/portfolio/update}" th:method="patch" th:object="${project}" enctype="multipart/form-data">
<div >
<input type="text" th:field="*{title}" id="title" th:value="${project.getTitle()}">
<div style="color:red" th:if="${#fields.hasErrors('title')}" th:errors="*{title}" >TITLE_ERROR</div>
</div>
<div >
<textarea placeholder="Описание проекта" type="text" th:field="*{description}" rows="7" cols="65" id="description" th:inline="text">
[[${project.getDescription}]]
</textarea>
<div style="color:red" th:if="${#fields.hasErrors('description')}" th:errors="*{description}" >DESCRIPTION_ERROR</div>
</div>
<input type="file" name="files" multiple>
<div th:text="${error}">FILE_ERR</div>
<div >
<button type="submit" >Обновить проект</button>
</div>
</form>
CodePudding user response:
you can not use 'PATCH' for the form method attribute. only 'GET' and 'POST' methods are allowed(source).
