Spring MVC: Multiple Row Form Submit using List of Beans

Recently I had a requirement where using Spring MVC we had to take inputs multiple rows of data from user. The form had many rows which user can edit and submit. Spring MVC provides very simple yet elegant way of collecting data from multiple rows from HTML form and store them in List of Beans in Java.

Lets look at the requirement first. We have a screen where data for multiple Contacts is displayed. The Contact data is displayed in an HTML table. Each row in the table represents a single contact. Contact details consist of attributes such as Firstname, Lastname, Email and Phone number.

The Add Contact form would look like following:

Lets see the code behind this example.

Tools and Technologies used:

  1. Java 5 or above
  2. Eclipse 3.3 or above
  3. Spring MVC 3.0

Step 1: Create Project Structure


Open Eclipse and create a Dynamic Web Project.

Enter project name as SpringMVC_Multi_Row and press Finish.

Step 2: Copy Required JAR files


Once the Dynamic Web Project is created in Eclipse, copy the required JAR files under WEB-INF/lib folder. Following are the list of JAR files:

Step 3: Adding Spring MVC support

Once the basic project setup is done, we will add Spring 3 MVC support. For that first modify default web.xml and add springs DispatcherServlet.

File: /WebContent/WEB-INF/web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>Spring3MVC-Multi-Row</display-name> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping> </web-app>
Code language: HTML, XML (xml)

Related: Tutorial: Learn Spring MVC Lifecycle

Now add spring-servlet.xml file under WEB-INF folder.

File: /WebContent/WEB-INF/spring-servlet.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <context:annotation-config /> <context:component-scan base-package="net.viralpatel.spring3.controller" /> <bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
Code language: HTML, XML (xml)

Note that in above spring-servlet file, line 10, 11 defines context:annotation-config and component-scan tags. These tags let Spring MVC knows that the spring mvc annotations are used to map controllers and also the path from where the controller files needs to be loaded. All the files below package net.viralpatel.spring3.controller will be picked up and loaded by spring mvc.

Step 4: Add Spring Controller and Form classes

File: /src/net/viralpatel/spring3/form/Contact.java

package net.viralpatel.spring3.form; public class Contact { private String firstname; private String lastname; private String email; private String phone; public Contact() { } public Contact(String firstname, String lastname, String email, String phone) { this.firstname = firstname; this.lastname = lastname; this.email = email; this.phone = phone; } // Getter and Setter methods }
Code language: Java (java)

File: /src/net/viralpatel/spring3/form/ContactForm.java

package net.viralpatel.spring3.form; import java.util.List; public class ContactForm { private List<Contact> contacts; public List<Contact> getContacts() { return contacts; } public void setContacts(List<Contact> contacts) { this.contacts = contacts; } }
Code language: Java (java)

Note line 7 in above code how we have defined a List of bean Contact which will hold the multi-row data for each Contact.

File: /src/net/viralpatel/spring3/controller/ContactController.java

package net.viralpatel.spring3.controller; import java.util.ArrayList; import java.util.List; import net.viralpatel.spring3.form.Contact; import net.viralpatel.spring3.form.ContactForm; import org.springframework.stereotype.Controller; 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 ContactController { private static List<Contact> contacts = new ArrayList<Contact>(); static { contacts.add(new Contact("Barack", "Obama", "[email protected]", "147-852-965")); contacts.add(new Contact("George", "Bush", "[email protected]", "785-985-652")); contacts.add(new Contact("Bill", "Clinton", "[email protected]", "236-587-412")); contacts.add(new Contact("Ronald", "Reagan", "[email protected]", "369-852-452")); } @RequestMapping(value = "/get", method = RequestMethod.GET) public ModelAndView get() { ContactForm contactForm = new ContactForm(); contactForm.setContacts(contacts); return new ModelAndView("add_contact" , "contactForm", contactForm); } @RequestMapping(value = "/save", method = RequestMethod.POST) public ModelAndView save(@ModelAttribute("contactForm") ContactForm contactForm) { System.out.println(contactForm); System.out.println(contactForm.getContacts()); List<Contact> contacts = contactForm.getContacts(); if(null != contacts && contacts.size() > 0) { ContactController.contacts = contacts; for (Contact contact : contacts) { System.out.printf("%s \t %s \n", contact.getFirstname(), contact.getLastname()); } } return new ModelAndView("show_contact", "contactForm", contactForm); } }
Code language: Java (java)

In above ContactController class, we have defile two methods: get() and save().

get() method: This method is used to display Contact form with pre-populated values. Note we added a list of contacts (Contacts are initialize in static block) in ContactForm bean object and set this inside a ModelAndView object. The add_contact.jsp is displayed which in turns display all contacts in tabular form to edit.

save() method: This method is used to fetch contact data from the form submitted and save it in the static array. Also it renders show_contact.jsp file to display contacts in tabular form.

Step 5: Add JSP View files

Add following files under WebContent/WEB-INF/jsp/ directory.

File: /WebContent/WEB-INF/jsp/add_contact.jsp

<%@taglib uri="http://www.springframework.org/tags" prefix="spring"%> <%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%> <%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> <html> <head> <title>Spring 3 MVC Multipe Row Submit - viralpatel.net</title> </head> <body> <h2>Spring MVC Multiple Row Form Submit example</h2> <form:form method="post" action="save.html" modelAttribute="contactForm"> <table> <tr> <th>No.</th> <th>Name</th> <th>Lastname</th> <th>Email</th> <th>Phone</th> </tr> <c:forEach items="${contactForm.contacts}" var="contact" varStatus="status"> <tr> <td align="center">${status.count}</td> <td><input name="contacts[${status.index}].firstname" value="${contact.firstname}"/></td> <td><input name="contacts[${status.index}].lastname" value="${contact.lastname}"/></td> <td><input name="contacts[${status.index}].email" value="${contact.email}"/></td> <td><input name="contacts[${status.index}].phone" value="${contact.phone}"/></td> </tr> </c:forEach> </table> <br/> <input type="submit" value="Save" /> </form:form> </body> </html>
Code language: HTML, XML (xml)

In above JSP file, we display contact details in a table. Also each attribute is displayed in a textbox. Note that modelAttribute=”contactForm” is defined in <form:form /> tag. This tag defines the modelAttribute name for Spring mapping. On form submission, Spring will parse the values from request and fill the ContactForm bean and pass it to the controller.

Also note how we defined textboxes name. It is in form contacts[i].a. Thus Spring knows that we want to display the List item with index i and its attribute a.

contacts[${status.index}].firstname will generate each rows as follows:

contacts[0].firstname // mapped to first item in contacts list
contacts[1].firstname // mapped to second item in contacts list
contacts[2].firstname // mapped to third item in contacts list

Spring 3 MVC and path attribute and square bracket

One thing here is worth noting that we haven’t used Spring’s tag to render textboxes. This is because Spring MVC 3 has a unique way of handling path attribute for tag. If we define the textbox as follows:

<form:input path="contacts[${status.index}].firstname" />
Code language: HTML, XML (xml)

Then instead of converting it to following HTML code:

<input name="contacts[0].firstname" /> <input name="contacts[1].firstname" /> <input name="contacts[2].firstname" />
Code language: HTML, XML (xml)

It converts it into following:

<input name="contacts0.firstname" /> <input name="contacts1.firstname" /> <input name="contacts2.firstname" />
Code language: HTML, XML (xml)

Note how it removed square brackets [ ] from name attribute. In previous versions of Spring (before 2.5) the square bracket were allowed in name attribute.

It seems w3c has later changed the HTML specification and removed [ ] from html input name.
Read the specification http://www.w3.org/TR/html4/types.html#type-name. It clearly says that:

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens (“-“), underscores (“_”), colons (“:”), and periods (“.”).

Thus, square brackets aren’t allowed in name attribute! And thus Spring 3 onwards this was implemented.

So far I haven’t got any workaround to use springs <form:input /> tag instead of plain html <input /> to render and fetch data from multiple rows.

File: /WebContent/WEB-INF/jsp/show_contact.jsp

<%@taglib uri="http://www.springframework.org/tags" prefix="spring"%> <%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%> <%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> <html> <head> <title>Spring 3 MVC Multipe Row Submit - viralpatel.net</title> </head> <body> <h2>Show Contacts</h2> <table width="50%"> <tr> <th>Name</th> <th>Lastname</th> <th>Email</th> <th>Phone</th> </tr> <c:forEach items="${contactForm.contacts}" var="contact" varStatus="status"> <tr> <td>${contact.firstname}</td> <td>${contact.lastname}</td> <td>${contact.email}</td> <td>${contact.phone}</td> </tr> </c:forEach> </table> <br/> <input type="button" value="Back" onclick="javascript:history.back()"/> </body> </html>
Code language: HTML, XML (xml)

File: /WebContent/index.jsp

<jsp:forward page="get.html"></jsp:forward>
Code language: HTML, XML (xml)

    Hi good simple application , i have small doubt here, when i run this application , how add_contact.jsp is getting displayed , u did not mention index.jsp any where , how it is directly forwarding to add_contact .jsp , is this the behaviour of the Dispatcher Servlet .
    Can any one reply to this.

    • Hi, add_contact.jsp is displayed via Spring controller. The get() method of ContactController renders add_contact page as you can see it in source code. I strongly recommend you to go through Spring MVC tutorial series to understand these concepts.

      • Dinu says:

        In the same example if u try to create a FormValidator and had to put error messages for all fileds what path value will u mention.
        suppose for the below field

        Please reply.Thanks.

    • Eswar says:

      What ever u said is true, but my doubt is how the controller is detecting index.jsp which contains “get.html” , which takes to Controller and results to add_contact.jsp ,

      How controller detects index.jsp which is not even declared as welcome file in web.xml

      • By default, tomcat (or other JEE Containers) renders index.jsp from WebContent folder. Although we havn’t defined index.jsp as welcome file, still by default it takes as welcome file. Read more

    For example:

    In my case i’m doing the exact thing and it works for 1 row created statically like above.
    But if i add another row dynamically like this (array index 1) using javascript

    it doesn’t work. On the server side because of the lazy list i see the size is 2 but field itself is null. Please help. I’m almost going mad.

    Spring has apparently corrected the value generated in the name=”…” parameter so that it conforms to the w3c spec!

    Woo hoo!

  57. Ninju Bohra says:

    Hmm looks like the commenting did not come across properly.

    You can you use

    <form:input path="..." />

    as was a way to express the input fields…Spring MVC has updated their code to be w3c compliant

    Hey, Please can you provide the example of webflow example with multiple controller

  59. Saurabh Mehta says:


    Here you populated the list before viewing it on “add_contact.jsp”. I have a requirement where user can add n number of objects at runtime from view layer.

    Please suggest.


    • That should’nt be a problem. You can define a method in ContactController to add new users in List contacts. Map this new method using @RequestMapping(“/adduser”). Hope you got whats to be done here.

  60. Jason says:

    Actually w3c spec is not saying “name” attribute in “input” element can’t have square bracket. The “NAME” is just its internal term to categorize attribute. See this and find “name” attribute for “input” element:
    The attribute type is CDATA! There is little restriction for CDATA type, see

  61. Interesting says:

    Nice example…btw, Spring 3.2.2 form:input works and will create the same hand-coded input.

    However, I noticed that on submission, Spring creates new instances of Contact and does not reuse the Contact instances that were populated in the ContactForm at form get time…

    I wonder if I set something up incorrectly.

  62. Interesting says:

    Following up on my observation: if I use @SessionAttribute(“myFormObject”) then it works fine…Spring 3.2.2

      Create new domain class like studentList.class. Declare the following variable.

      List&lt;List&lt;Student&gt;&gt; studentList=new ArrayList&lt;List&lt;Student&gt;&gt;(); 

      In front end :

      studentList[${0.index}][${0.index}].subject, studentList[${0.index}][${0.index}].time, studentList[${0.index}][${1.index}].subject, studentList[${0.index}][${1.index}].time 

      . its exactly like matrix .

  71. ammy says:

    What if you dont know contacts size already, how do you do, in my case I don’t know the table size which is going to be enter, it’s dynamic, it has add row button.
    can you please suggest how should I do?

  72. Mona says:

    Hi Viral,
    Nice explaination. But I need to save multi rows of table where no. of columns in table is not fixed it is also dynamic or user configuration value that can be fetched from DB at time of form load. Hence, bean structure is not fixed, so no bean like contact can be defined. Only info to relate with is header-name, row-value and row-no. Hence row-values for all header-names corresponding to single row-no. form a single row of table.
    Do you have any idea of implementing Save for this kind of scenerio.

  73. Abdul Vasih says:

    Thanks a lot Viral.., good example and excellent explanation! :)

  88. Ritesh Phokmare says:

    Hi Viral,

    I have a same situation but one of the attribute of the list object is an object i.e. ithis case :
    public class Contact {
    private String firstname;
    private String lastname;
    private String email;
    private String phone;
    private ClassName obj_name;

    I creating an object of ClassName and assing to every Contact object of list but on form submit I am getting the value of object obj_nmae as null.

    What could be the reason for this???

  89. ananomuous says:

    its sending null over post request and model attribute coming null at controller . Not able to figure out?

  90. Venkatesh Manohar says:

    Very nice article. I had to create a similar page and this tutorial provided me overview of how to go about it.
    Thanks and keep up the good work.

  91. Isaac Jefferson says:

    Very good article.

    I have tried with a checkbox instead of textbox (used in this sample) and binding it with a boolean variable. The textbox changes are reflecting but the checkbox changes are not getting updated in the pojo.

    • Isaac Jefferson says:

      I finally got the solution ,

      • Isaac Jefferson says:

        form:checkbox path=”contacts[${status.index}].delete”

  92. This thing is not going to work. Try start with two browsers and enter different data, play around see what hapened. it is going to corrupt each other. The reason the controller is stateless, should not have field ‘Contacts’.

  93. Vijay says:

    Nice Explanation. But I have a situation where I dont have list of beans initially. User can add and deleter rows on form. Initially row will be empty and user will fill the data and submit the form. Do you have any suggestion for this?

  94. Ankit Pandey says:

    Hi in my case when i am submitting the form after editing i am getting an exception like…

      Did you find any solution?


      • Sudip says:

        I know its too late to answer this but it may help someone. I also faced the same issue and the solution to this is in case you forgot to add the blank constructor in Contact.java do add this as below:

        public Contact(){

        • Sudip says:

          Also make sure you have all the getters and setters in the Contact.java file.

  95. David RION says:

    Hi ! Very usefull article !

    In your example you use only a list of contact.
    Byt what if the Bean Contact get a list too. How do you process to display the information ?

    Like that ?
