java - Spring 验证中的 ClassNotFound 异常

Question

我正在尝试在 Spring 中使用 NetBeans IDE 中的 hibernate-validator 进行服务器端验证。 我遇到以下异常。

异常(exception):

Controller :

@RequestMapping(value = "/Register", method = RequestMethod.POST)
public ModelAndView Registeruser(@ModelAttribute("registerBean") @Valid RegisterBean registerBean, BindingResult bindingResult) {
    ModelAndView model;
    if (bindingResult.hasErrors()) {
        model = new ModelAndView("index");
    } else {
        boolean registered = userservice.RegisterUser(registerBean);
        if (registered) {
            Userdetails userDetails = this.getUserDetails();
            model = new ModelAndView("/auth/Home", "user", userDetails);
        } else {
            model = new ModelAndView("index","message","Error occured at server please try later");
        }
    }
    return model;
}

Answer 1

我通过在dispatcher-servlet.xml中添加 validator bean解决了这个问题

 <bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" />
