Я только что создал свой контроллер, однако, когда я пытаюсь запустить свое приложение, я получаю сообщение об ошибке, указанное в заголовке.
Я потратил некоторое время, возиться с моим контроллером и не вижу дубликатовотображения, так что не совсем уверен, что происходит не так.Ниже мой контроллер:
@Controller
public class CSPServerController {
@Autowired
ServerService serverService;
@Autowired
AuditLogService auditLogService;
@RequestMapping(name = "/servers", method = RequestMethod.GET)
@PreAuthorize("hasRole(T(com.nathanenglish.serverlldmanagementtool.config.GlobalConfig).RoleReadOnly)")
public String loadServers(Model model){
model.addAttribute("servers",serverService.getAll());
return "servers";
}
@RequestMapping(name = "/servers/new", method = RequestMethod.GET)
@PreAuthorize("hasRole(T(com.nathanenglish.serverlldmanagementtool.config.GlobalConfig).RoleEdit)")
public String newServer(Model model){
model.addAttribute("server", new Server());
model.addAttribute("auditLog", new AuditLog());
return "server";
}
@RequestMapping(name = "/servers/{id}", method = RequestMethod.GET)
@PreAuthorize("hasRole(T(com.nathanenglish.serverlldmanagementtool.config.GlobalConfig).RoleEdit)")
public String getServer(@PathVariable Long id, Model model){
model.addAttribute("server", serverService.getById(id));
model.addAttribute("auditLog", new AuditLog());
return "server";
}
@RequestMapping(name = "/servers/save", method = RequestMethod.POST)
@PreAuthorize("hasRole(T(com.nathanenglish.serverlldmanagementtool.config.GlobalConfig).RoleEdit)")
public String saveServer(Model model, @Valid Server server, @Valid AuditLog auditLog, BindingResult bindingResult){
if(bindingResult.hasErrors()){
return "server";
}
serverService.save(server);
auditLogService.save(auditLog);
return "redirect:/servers";
}
@RequestMapping(name = "/servers/delete/{id}", method = RequestMethod.GET)
@PreAuthorize("hasRole(T(com.nathanenglish.serverlldmanagementtool.config.GlobalConfig).RoleEdit)")
public String deleteServer(@PathVariable Long id, Model model){
serverService.deleteByID(id);
return "redirect:/servers";
}
}
