我想检查studentHobby对象的大小验证，我正在使用 @Size 注释和使用 @valid 注释。

我提供的值小于@Size 注释中定义的值，但我仍然得到结果而不是错误。

我尝试了一些东西，但没有找到解决方案。

StudentAdmissionController.java

package com.diwakar;

import javax.validation.Valid;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.InitBinder;
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.servlet.ModelAndView;


@Controller
public class StudentAdmissionController {

    @InitBinder
    public void initBinder(WebDataBinder binder) {
        //binder.setDisallowedFields(new String[] {"studentMobile"});
        //SimpleDateFormat date = new SimpleDateFormat("dd**MM**yyyy");
        //binder.registerCustomEditor(Date.class, "studentDOB", new CustomDateEditor(date, false)); 
        binder.registerCustomEditor(String.class, "studentName", new StudentNameEditor());
    }

    @RequestMapping(value="/admission.html", method = RequestMethod.GET)
    public ModelAndView getAdmissionForm() {

        ModelAndView model =  new ModelAndView("AdmissionForm");
        //model.addObject("headerMessage", "Diwakar College of Engineering.!!");
        return model;
    }

    @RequestMapping(value="/submitForm", method =  RequestMethod.POST)
    public ModelAndView submitAdmissionForm(@Valid @ModelAttribute("st1") Student st1, BindingResult result) {

        if (result.hasErrors()) {
            ModelAndView model =  new ModelAndView("AdmissionForm");
            return model;
        }

        ModelAndView model = new ModelAndView("AdmissionSuccess");
        //model.addObject("headerMessage", "Diwakar College of Engineering.!!");
        return model;
    }   

    @ModelAttribute
    public void addCommonMessage(Model model) {
        model.addAttribute("headerMessage", "Diwakar College of Engineering.!!");
    }

学生.java

package com.diwakar;

import java.util.ArrayList;
import java.util.Date;

import javax.validation.constraints.Size;

public class Student {

    private String studentName;

    @Size(min=3, max=10)
    private String studentHobby;

    private Long studentMobile;

    private Date studentDOB;
    private ArrayList<String> studentSkills;
    private Address studentAddress;

    public String getStudentName() {
        return studentName;
    }
    public void setStudentName(String studentName) {
        this.studentName = studentName;
    }
    public String getStudentHobby() {
        return studentHobby;
    }
    public void setStudentHobby(String studentHobby) {
        this.studentHobby = studentHobby;
    }
    public Long getStudentMobile() {
        return studentMobile;
    }
    public void setStudentMobile(Long studentMobile) {
        this.studentMobile = studentMobile;
    }
    public Date getStudentDOB() {
        return studentDOB;
    }
    public void setStudentDOB(Date studentDOB) {
        this.studentDOB = studentDOB;
    }
    public ArrayList<String> getStudentSkills() {
        return studentSkills;
    }
    public void setStudentSkills(ArrayList<String> studentSkills) {
        this.studentSkills = studentSkills;
    }
    public Address getStudentAddress() {
        return studentAddress;
    }
    public void setStudentAddress(Address studentAddress) {
        this.studentAddress = studentAddress;
    }   
}
