Spring MVC textbox example

In Spring MVC, you can use <form:input /> tag to render a HTML textbox field. For example,

<form:input path="userName" />

It will renders following HTML code

<input id="userName" name="userName" type="text" value=""/>

In this tutorial, we show you how to use Spring’s form tag “input” to render a HTML textbox to store the “userName“. Additionally, add an empty check validator to make sure the textbox value is not empty.

1. Controller

A SimpleFormController to handle the form value, and link the form value to the Customer object.

File : TextBoxController.java

package com.mkyong.customer.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import com.mkyong.customer.model.Customer;
public class TextBoxController extends SimpleFormController{
	public TextBoxController(){
	protected ModelAndView onSubmit(HttpServletRequest request,
		HttpServletResponse response, Object command, BindException errors)
		throws Exception {
		Customer customer = (Customer)command;
		return new ModelAndView("CustomerSuccess","customer",customer);

2. Model

A Customer object to store the text box value.

File : Customer.java

package com.mkyong.customer.model;
public class Customer{
	String userName;
	//getter and setter methods

3. Form Validator

Create a form validator class and use the ValidationUtils class to make sure the “userName” is not empty, Otherwise, get the “required.userName” message from the corresponds resource bundle (properties file).

File : CustomerValidator.java

package com.mkyong.customer.validator;
import org.springframework.validation.Errors;
import org.springframework.validation.ValidationUtils;
import org.springframework.validation.Validator;
import com.mkyong.customer.model.Customer;
public class CustomerValidator implements Validator{
	public boolean supports(Class clazz) {
		//just validate the Customer instances
		return Customer.class.isAssignableFrom(clazz);
	public void validate(Object target, Errors errors) {
		ValidationUtils.rejectIfEmptyOrWhitespace(errors, "userName",
			"required.userName", "Field name is required.");

File : message.properties

required.userName = username is required!

4. View

A JSP page to use the Spring’s form tag “input” to render a HTML textbox, and put some CSS styles to highlight the error message.

File : CustomerForm.jsp

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
.error {
	color: #ff0000;
.errorblock {
	color: #000;
	background-color: #ffEEEE;
	border: 3px solid #ff0000;
	padding: 8px;
	margin: 16px;
	<h2>Spring's form textbox example</h2>
	<form:form method="POST" commandName="customerForm">
		<form:errors path="*" cssClass="errorblock" element="div" />
				<td>Username :</td>
				<td><form:input path="userName" />
				<td><form:errors path="userName" cssClass="error" />
				<td colspan="3"><input type="submit" />

If the form is submitted, render the successful page and display the submitted textbox value.

File : CustomerSuccess.jsp

	<h2>Spring's form textbox example</h2>
	userName : ${customer.userName}

5. Spring Bean Configuration

Link it all ~

<beans xmlns="http://www.springframework.org/schema/beans"
  class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />
	<bean class="com.mkyong.customer.controller.TextBoxController">
		<property name="formView" value="CustomerForm" />
		<property name="successView" value="CustomerSuccess" />
		<!-- Map a validator -->
		<property name="validator">
			<bean class="com.mkyong.customer.validator.CustomerValidator" />
	<!-- Register the Customer.properties -->
	<bean id="messageSource"
		<property name="basename" value="message" />
	<bean id="viewResolver"
		<property name="prefix">
		<property name="suffix">

6. Demo

Access the page – http://localhost:8080/SpringMVCForm/textbox.htm


If the textbox value is empty while submitting the form, display and highlight the error message.


If the form is submitted successfully, just display the submitted textbox value.

    I have form which has object in it. that object has a list of object (which has variables on form view) so something like this:
    -> Obj1
    -> List
    and Obj2 has fields like title, firstname, lastname etc.
    Now I want to assign textbox value to field in Obj2 (say to title).
    I tried using obj1.obj[0].title however this does not work.

    Could you please comment.

    Your Explaination :

    It will renders following HTML code

    Mine :

    I believe will result in

    therefore it will also consider value=”userName” if we expect our textbox to be prefilled.

  • eladerezador

    I’m new to Spring, the example is already set in STS, but when I call locally to: http://localhost:8080/SpringMVCForm/textbox.htm, the browser gives the following error “Estate HTTP 404 – /SpringMVCForm/textbox.htm”

    Could you please tell me why this happens?
