This was a subject I thought I had down pack but apparently I was wrong. App is crashing giving the error above and the print trace below. Ironically, App did work at one point but when I assed something it started crashing. Thanks for any ideas.
Controller:
@Controller
public class ManagerController {
private ManagerService managerService;
@Autowired
public void setManagerService(ManagerService managerService){
this.managerService = managerService;
}
@RequestMapping("/add-manager")
public String showManagerPage(Model model){
List<Manager> managers = managerService.findAllManagers();
model.addAttribute("managers", managers);
return "add-manager";
}
@GetMapping("/showManagerForm")
public String addManagerForm(Model model){
model.addAttribute("manager", new Manager());
return "add-manager";
}
@PostMapping("/saveManager")
public String postManagerForm(@ModelAttribute("manager") Manager manager){
managerService.saveManager(manager);
return "add-manager";
}
}

It seems that all your methods are redirecting to the page that is showing the manager form, if this is what you want, you'll need to add the Manager object to the Model object in each of those methods :
@Controller
public class ManagerController {
private ManagerService managerService;
@Autowired
public void setManagerService(ManagerService managerService){
this.managerService = managerService;
}
@RequestMapping("/add-manager")
public String showManagerPage(Model model){
List<Manager> managers = managerService.findAllManagers();
model.addAttribute("managers", managers);
model.addAttribute("manager", new Manager());
return "add-manager";
}
@GetMapping("/showManagerForm")
public String addManagerForm(Model model){
model.addAttribute("manager", new Manager());
return "add-manager";
}
@PostMapping("/saveManager")
public String postManagerForm(@ModelAttribute("manager") Manager manager, Model model){
managerService.saveManager(manager);
model.addAttribute("manager", new Manager());
return "add-manager";
}
}
UPDATE
As M. Deinum point out, you can use the @ModelAttribute annotation on a method instead adding the Manager in each method :
@Controller
public class ManagerController {
private ManagerService managerService;
@Autowired
public void setManagerService(ManagerService managerService){
this.managerService = managerService;
}
@ModelAttribute
public Manager manager() {
return new Manager();
}
@RequestMapping("/add-manager")
public String showManagerPage(Model model){
List<Manager> managers = managerService.findAllManagers();
model.addAttribute("managers", managers);
return "add-manager";
}
@GetMapping("/showManagerForm")
public String addManagerForm(Model model){
return "add-manager";
}
@PostMapping("/saveManager")
public String postManagerForm(@ModelAttribute("manager") Manager manager, Model model){
managerService.saveManager(manager);
return "add-manager";
}
}
