Spring MVC form error - java

I am trying to run a project in Spring MVC. Here is the code

In the above program, Whenever I go to http://localhost:8080/SpringRegister/index.htm, I always gets this error
Error:
neither bindingresult nor plain target object for bean 'userForm' available as request attribute
What is wrong with the code?

When you hit the http://localhost:8080/SpringRegister/index.htm from browser, Your request is handled by ParameterizableViewController which does not set the model attribute (userForm) and forwards to index.jsp, the index.jsp's form tag expects the model attribute userForm <form:form action="${pageContext.request.contextPath}/register" method="POST" modelAttribute="userForm"> , which is not available. that why the error. To resolve this you can create your own conrtoller which handles your http://localhost:8080/SpringRegister/index.htm URL,
ModelAndView modelAndView = new ModelAndView("your view name");
model.addAttribute("userForm", new User());
configure that controller instead of class="org.springframework.web.servlet.mvc.ParameterizableViewController" in your servlet xml. Hope this helps.

You need to Change in Controller To bind userForm with Bean ----
Jsp Form --
<form:form action="userAction" modelAttribute="userForm " class="form-search" role="form">
Controller --
#RequestMapping (value = "/userAction")
public ModelAndView checkFeasibility(#ModelAttribute("userForm ")User userForm)
{
// Any Action
model.addObject("userForm",userForm);
return model;
}
In order to Bind userForm modelAttribute of form with User Bean.

Hibernate validator doesn't work

I'm using Hibernate validator with Hibernate and Spring, but it seems that validations don't work. When I don't enter a String or enter a String of 1 character (which is not between min=4 and max=20) is not showing any error and therefore saves in the table. What am I missing?

Finally I found the error ,
the problem was that I didin't add hibernate-validator jar I only added files in the dist/lib/required :
classmate-1.3.1
javax.el-2.2.4
-javax.el-api-2.2.2
jboss-logging-3.3.0.Final
validation-api-1.1.0
So if that happens to someone just add : hibernate-validator-5.3.2.Final.

After spent one hour to study two validation tutorials:
Hibernate Validator Annotations Example
Spring MVC Form Validation Annotation Example
I suggest you some solutions.
1) Verify hibernate validation annotation working or not
ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
Validator validator = factory.getValidator();
Set<ConstraintViolation<Etudiant>> constraintViolations = validator.validate(etudiant);
2) You can create custom validator, for example EtudiantValidator, then validate manually like below:
#RequestMapping(value="save",method=RequestMethod.POST)
public String saveetudient(Model md,#ModelAttribute("etudiant") Etudiant etudiant, BindingResult res){
new EtudiantValidator().validate(etudiant, result);
...
}
However I deep into your code,I see that you have a mistake on this method:
#RequestMapping(value="save",method=RequestMethod.POST)
public String saveetudient(Model md,
#Valid #ModelAttribute("etudiant") Etudiant et,
BindingResult res)
Should change it to like below
#RequestMapping(value="save",method=RequestMethod.POST)
public String saveetudient(Model md,
#Valid #ModelAttribute("etudiant") Etudiant etudiant,
BindingResult res)
Hope this help!

Question: what can be a reson of this exception? How to fix it?

In controller redirection use only index instead of index.html. it will redirect to index method of controller.And you can view the output on index page itself after clicking on button.
As shown below:
#RequestMapping(value = "/Add", method = RequestMethod.POST)
public String add(#ModelAttribute ("usr") User user){
if (null != user && null != user.getFirstname()
&& null != user.getLastname() && !user.getFirstname().isEmpty()
&& !user.getLastname().isEmpty()) {
synchronized (userList) {
userList.add(user);
}
}
return "redirect:index";

Spring MVC Errors are not shown to user

I am trying to learn spring MVC. I have a User Registration form which has some validations to be applied. I have written a controller for it and used javax validation annotations on the model class i.e. UserBo.
I have used Spring MVC tag to show any errors found by #Valid annotation. However, the errors are not visible on screen.
Following are the files in my setup.
The Model: UserBO
package com.shailesh.beans;
import javax.validation.constraints.NotNull;
public class UserBO {
public enum MaritalStatus {
SINGLE, MARRIED
}
#Override
public String toString() {
return "UserBO [firstName=" + firstName + ", lastName=" + lastName
+ ", id=" + id + ", phone=" + phone + ", maritalStatus="
+ maritalStatus + "]";
}
#NotNull(message="First Name can not be null")
private String firstName;
#NotNull
private String lastName;
#NotNull
private Long id;
#NotNull
private String phone;
#NotNull
private MaritalStatus maritalStatus;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public MaritalStatus getMaritalStatus() {
return maritalStatus;
}
public void setMaritalStatus(MaritalStatus maritalStatus) {
this.maritalStatus = maritalStatus;
}
}
The Controller : AllPathController
package com.shailesh.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 com.shailesh.beans.UserBO;
#Controller
public class AllPathController {
#RequestMapping(value="/register", method=RequestMethod.GET)
public String register(Model model) {
model.addAttribute("userBo", new UserBO());
return "registerform";
}
#RequestMapping(value="/register", method=RequestMethod.POST)
public String register(#Valid #ModelAttribute("userBo") UserBO userBo, BindingResult result, Model model) {
if(result.hasErrors()) {
System.out.println("Input has some errors :"+result.toString());
//model.addAttribute("userBo", userBo);
return "registerform";
}
System.out.println("Input user details :" +userBo);
return "helloboss";
}
#RequestMapping(value="/homepage", method=RequestMethod.GET)
public String show() {
return "homepage";
}
#RequestMapping(value="/helloboss.do", method=RequestMethod.GET)
public String show2() {
System.out.println("get");
return "helloboss";
}
#RequestMapping(value="/helloboss.do", method=RequestMethod.POST)
public String show3() {
System.out.println("post");
return "hellobosspost";
}
}
The Spring context.xml file :

</sf:select>
<sf:errors path="maritalStatus" />
<input type="submit" value="Register" />
</sf:form>
</body>
</html>
My observation is, when i give path value for as "*", it works. However, when i use some specific value ex. firstName , it doesn't show any errors. I tried debugging in this case. I can see the errors being populated inside BindingResult but not shown on UI.
Any help is appeciated. Thanks.

My Code is working well but it does not displays error messages in <form:errors />.
please help me.

The third parameter to ValidationUtils.rejectIfEmpty is an error code. It should be a key to the actual message in your resource bundle. I don't know how it behaves if it can't find a value. You should change it to use a key, and optionally set a default message. See the api.

You need to register your validator with the controller in which you want to use it. See: http://static.springsource.org/spring/docs/3.0.0.RC3/reference/html/ch05s07.html#validation.mvc
