Neither BindingResult nor plain target object available as request attribute
If you are trying to bind a Spring MVC form to a bean, then you might have come across the below exception.
Neither BindingResult nor plain target object for bean name ‘mybean’ available as request attribute
Some tutorials claim that you can do like this:
@Controller
public class PersonController {
@RequestMapping(value = "/person/add", method = RequestMethod.GET)
public String add(Model model) {
model.addAttribute("person", new Person());
return "add-person";
}
@RequestMapping(value = "/person/add", method = RequestMethod.POST)
public String processAdd(@Valid Person person, BindingResult bindingResult) {
if (bindingResult.hasErrors()) {
return "add-person";
}
return "person-added-successfully";
}
}The above assumes a Spring form with a modelAttribute or commandName attribute with the value person. This code does, however, raise the following exception: Neither BindingResult nor plain target object for bean name ‘mybean’ available as request attribute.
This used to work in previous versions of Spring, but it no longer seems to work (currently version 4.1.4). To solve this, you have to add a @ModelAttribute annotation before your bean argument in the controller action with the POST request method. Below is a working example.
@Controller
public class PersonController {
@RequestMapping(value = "/person/add", method = RequestMethod.GET)
public String add(Model model) {
model.addAttribute("person", new Person());
return "add-person";
}
@RequestMapping(value = "/person/add", method = RequestMethod.POST)
public String processAdd(@Valid @ModelAttribute("person") Person person, BindingResult bindingResult) {
if (bindingResult.hasErrors()) {
return "add-person";
}
return "person-added-successfully";
}
}And the corresponding view:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<c:url var="actionUrl" value="/person/add" />
<form:form action="${actionUrl}" modelAttribute="person" method="POST" acceptCharset="UTF-8">
<form:input path="firstName" />
<form:errors path="firstName" />
<form:input path="lastName" />
<form:errors path="lastName" />
<form:button id="add-person">Add Person</form:button>
</form:form>The Person class is just a simple bean like the below.
public class Person {
@NotEmpty
private String firstName;
@NotEmpty
private String lastName;
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getFirstName() {
return this.firstName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getLastName() {
return this.lastName;
}
}Note that I am using JSR-303 bean validation with the Hibernate Validator implementation. If you do not, then you can simply remove the annotations from the bean class as well as the @Valid annotation in the arguments of the processAdd controller action.
That is all there is to it. At least it worked for me, and hopefully it will work for you too.

Kindly guide me to overcome this error.
Thanks in advance.

So this error only occurs because of the spring versions? If so, hwta was changed from the older spring compared to 4.x.x…
