嗨，我试图将验证放在我的春季项目中，但它对我不起作用，我还将所有必需的验证器jar添加到我的lib文件夹中。
我的控制器类看起来像
package qm;
import java.sql.Date;
import java.text.SimpleDateFormat;
import javax.validation.Valid;
import org.springframework.beans.propertyeditors.CustomDateEditor;
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[] {"studentSkill","studentDOB"});
SimpleDateFormat dateFormat=new SimpleDateFormat("dd-mm-yyyy");
binder.registerCustomEditor(Date.class,"studentDOB", new CustomDateEditor(dateFormat, false));
}
@RequestMapping(value="/registration.html",method=RequestMethod.GET)
public ModelAndView getStudentAdmissionForm() {
ModelAndView model=new ModelAndView("AdmissionForm");
return model;
}
@ModelAttribute
public void addCommonObject(Model model) {
model.addAttribute("headerMessage","Q-Manager.com");
}
@RequestMapping(value="/submit-detail.html",method=RequestMethod.POST)
public ModelAndView studentDetail(@Valid @ModelAttribute("student1") Student student,BindingResult result) {
if(result.hasErrors()) {
ModelAndView model=new ModelAndView("AdmissionForm");
return model;
}
ModelAndView model=new ModelAndView("AdmissionSuccess");
return model;
}
}
我的学生课是
package qm;
import java.util.ArrayList;
import java.util.Date;
import javax.validation.constraints.Size;
public class Student {
@Size(min=2,max=30)
private String studentName;
private String studentHobby;
private Long studentMobile;
private Date studentDOB;
private ArrayList<String> studentSkill;
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> getStudentSkill() {
return studentSkill;
}
public void setStudentSkill(ArrayList<String> studentSkill) {
this.studentSkill = studentSkill;
}
public Address getStudentAddress() {
return studentAddress;
}
public void setStudentAddress(Address studentAddress) {
this.studentAddress = studentAddress;
}
}
我的地址类是
package qm;
public class Address {
private String country,city,street,pincode;
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getStreet() {
return street;
}
public void setStreet(String street) {
this.street = street;
}
public String getPincode() {
return pincode;
}
public void setPincode(String pincode) {
this.pincode = pincode;
}
}
这是我的AndissionForm.jsp
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form" %>
<html>
<head>
<title>Student Form</title>
</head>
<body>
<center><h4>${headerMessage}</h4></center>
<center><h4>Student Admission Form</h4></center>
<center>
<form:errors path="student1.*"/>
</center>
<form action="submit-detail.html" method="post">

</form>
</body>
</html>
任何人都建议我在哪里错了，所以我实际上会在以前的研究中更正我的代码>
- classmate-1.0.0 jars
- Hibernate-Validator-Annotation Processor-5.1.2.2.Final Jar
- jboss-logging-3.1.3.ga jar
- 验证-api-1.1.0.final
我使用了弹簧4.3。*此项目的罐子
尝试通过在pom.xml中添加以下依赖项
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>6.0.12.Final</version>
</dependency>
您需要在Spring Dispatcher中添加MVC注释标签。
<mvc:annotation-driven/>
