谢谢，将控制器方法的
@PostMapping（“/any url”）@GetMapping（“/any url”）@RequestMapping（“/any url”）@RequestMapping("/add")
public String addNewStudent( @ModelAttribute StudentEntity studentEntity, Model model) {
model.addAttribute("addStudent",studentRepository.save(studentEntity) );
return "/allstudents";
}
将控制器方法的
@PostMapping（“/any url”）@GetMapping（“/any url”）@RequestMapping（“/any url”）@RequestMapping("/add")
public String addNewStudent( @ModelAttribute StudentEntity studentEntity, Model model) {
model.addAttribute("addStudent",studentRepository.save(studentEntity) );
return "/allstudents";

在控制器中，您只有一个映射到
