Question

当我在spring mvc中页面加载时尝试将数据从控制器放入表单视图时出现问题。这是我的控制器：

@Controller
@RequestMapping("myaccount.htm")
public class MyAccountController {
    @Autowired
    private AccountValidation accountValidation;

    public void setAccountValidation(AccountValidation accountValidation){
        this.accountValidation = accountValidation;
    }

    @InitBinder
    public void initBinder(WebDataBinder binder) {
        binder.registerCustomEditor(String.class, new StringUTF8Editor(true));
    }

    @RequestMapping(method = RequestMethod.GET)
    public String showAccountForm(Map<String, AccountForm> model){
        AccountForm account = new AccountForm();
        model.put("accountform", account);
        return "myaccount";
    }

    @RequestMapping(method = RequestMethod.POST)
    public String processAccount(@Valid AccountForm accountForm,
            BindingResult result, Map<String, AccountForm> model, HttpSession session, HttpServletResponse response) {


        //I try put something model like this when load page
        AccountForm acc = new AccountForm();
        acc.setEmail("h@gmail.com");
        acc.setBirth("12/12/1989");
        acc.setPassword("user");
        acc.setPhone(21767621); 

        // but it only show when I submit 
        model.put("accountform", acc);
        if(result.hasErrors()){
            return "myaccount";
        }

        return "myaccount";
    }
}

你有什么建议吗？谢谢！

在处理POST请求期间，您不应初始化此数据，因为它会覆盖用户提供的数据。相反，您应该在showAccountForm()中设置默认值。甚至更多：使用@ModelAttribute来填充模型。

在加载时将模型数据放入Spring MVC中
