@Range not working in spring mvc
Question
I am using spring mvc and trying to validate user input in a form addGoal.jsp by using @Range in my model Goal .But if I enter value for ex 223 greater than 120 as I set in the annotation it prints Result Errors false (as I printed in updateGoal method in controller) and not routing to addGoal view I cant seem to understand why its not validating the result.hasErrors() giving me false even if I enter value that are not in range.
Model
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;
}
}
Controller
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";
}
}

In your pom you have the following dependency
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.2.0.Final</version>
<scope>provided</scope>
</dependency>
The culprit is <scope>provided</scope> . For Bean Validation to work there has to be an implementation on the class path. This is the case while coding, however it isn't the case when deployed (as the dependency isn't packaged in the war).
Spring will only register a LocalValidatorFactoryBean if there is a JSR-303 implementation available else it won't and the validations don't work.
The fix is to simply remove <scope>provided</scope> .

即使删除了作用域标记，我仍然面临着这个问题。然后我从本地存储库（即C：\\ Users \\ computerName \\ .m2 \\ repository \\ org \\ hibernate）删除了hibernate文件夹，然后使用maven update下载了所有与再次休眠。现在一切正常。
