我使用Spring MVC和試圖驗證用戶輸入的形式addGoal.jsp在我的模型Goal。但使用@Range如果我對前223大於120輸入值，因爲我在註釋設置它打印Result Errors false（因爲我在控制器updateGoal方法中打印），而不是路由到addGoal視圖我似乎不明白爲什麼它不驗證result.hasErrors()即使我輸入不在範圍內的值，我也是虛假的。@range不是Spring MVC中工作
模型
import org.hibernate.validator.constraints.Range;
public class Goal {
@Range(min = 1,max = 120) // validation not working
private int minutes;
public int getMinutes() {
return minutes;
}
public void setMinutes(int minutes) {
this.minutes = minutes;
}
}
控制器
import javax.validation.Valid;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.SessionAttributes;
import testspring.model.Goal;
@Controller
@SessionAttributes("goal")
public class GoalController {
@RequestMapping(value = "/addGoal",method = RequestMethod.GET)
public String addGoal(Model model){
Goal g=new Goal();
g.setMinutes(10);
model.addAttribute("goal", g);
return "addGoal";
}
@RequestMapping(value = "/addGoal",method = RequestMethod.POST)
public String updateGoal(@Valid @ModelAttribute ("goal") Goal goal,BindingResult result){
System.out.println("Result Errors "+result.hasErrors());
System.out.println("Minutes Updated "+goal.getMinutes());
if(result.hasErrors())
return "addGoal";
return "redirect:addMinutes.html";
}
}

您似乎沒有在任何地方定義的驗證器bean。 – chrylis
提供了您的hibernate-validator刪除範圍。 –
