<%@taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
A Simple example is given below that illustrates all the form tags
myForm.jsp
<%@taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<h2 align="center">Spring Form Tags</h2>
<form:form method="POST" name="myForm" commandName="myForm" action="#">
<table align="center" cellpadding="10" cellspacing="10"
bgcolor="#CCFFCC">
<tr>
<td><form:label path="hiddenField">Hidden Field</form:label></td>
<td><form:hidden path="hiddenField"></form:hidden></td>
</tr>
<tr>
<td><form:label path="textField">Text Field</form:label></td>

Bean class for the above form
SampleInterfaceImp.java
package net.roseindia.model;
import java.util.List;
import org.springframework.web.multipart.commons.CommonsMultipartFile;
public class MyForm {
private String textField;
private String hiddenField;
private String password;
private String radioButton;
private String select;
private List countryList;
private String textArea;
private String checkBox;
private CommonsMultipartFile file;
public String getHiddenField() {
return hiddenField;
}
public void setHiddenField(String hiddenField) {
this.hiddenField = hiddenField;
}
public String getTextField() {
return textField;
}
public void setTextField(String textField) {
this.textField = textField;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getRadioButton() {
return radioButton;
}
public void setRadioButton(String radioButton) {
this.radioButton = radioButton;
}
public String getSelect() {
return select;
}
public void setSelect(String select) {
this.select = select;
}
public List getCountryList() {
return countryList;
}
public void setCountryList(List countryList) {
this.countryList = countryList;
}
public String getTextArea() {
return textArea;
}
public void setTextArea(String textArea) {
this.textArea = textArea;
}
public String getCheckBox() {
return checkBox;
}
public void setCheckBox(String checkBox) {
this.checkBox = checkBox;
}
public CommonsMultipartFile getFile() {
return file;
}
public void setFile(CommonsMultipartFile file) {
this.file = file;
}
}
Controller for the form
SampleInterfaceImp.java
package net.roseindia.controller;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
import javax.validation.Valid;
import net.roseindia.model.Country;
import net.roseindia.model.MyForm;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class MyFormController {
@RequestMapping("/myForm.html")
public String loadForm(Map model, @Valid MyForm myForm) {
List countryList = new ArrayList();
countryList = loadCountry();
model.put("countryList", countryList);
return "myForm";
}
public List loadCountry() {
List countryList = new ArrayList();
countryList.add(new Country(1, "India", "Description Of India"));
countryList.add(new Country(2, "China", "Description Of China"));
countryList.add(new Country(3, "England", "Description Of England"));
countryList.add(new Country(4, "Srilanka", "Description Of Srilanka"));
countryList.add(new Country(5, "Kenya", "Description Of Kenya"));
return countryList;
}
}
The Country model class for displaying select, checkboxes and radiobutton groups
Country.java
package net.roseindia.model;
public class Country {
private int id;
private String name;
private String description;
public Country() {
}
public Country(int id, String name, String description) {
this.id = id;
this.name = name;
this.description = description;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
}
When you run this application it will display message as shown below:
