Spring form:option - spring-mvc

Question

Is there any way to mark an option as selected by default, much like the selected attribute in the HTML option tag like <option value="value1" selected>?

Answer 1

If the path value of the tag matches the value of options value it will automatically be selected. You don't need anything special

Answer 2

Is there any way to mark an option as selected by default ???
Just use <spring:option Taglib The first one will be automatically selected
<spring:select name="someProperty">
<spring:option value="">Select one</spring:option>
<spring:option value="someValue">Some value<spring:select>
<!--And so on...-->
<spring:select>
or
<spring:select name="someCollection">
<spring:option value="">Select one</spring:option>
<!--Here goes some List added to request-->
<spring:options itemLabel="propertyNameUsedAsLabel" itemValue="propertyNameUsedAsValue"/>
<!--And so on...-->
<spring:select>

I am assuming you are also using Spring MVC. If you have business logic that requires a certain option to be selected by default, move that business logic to the controller - not the JSP.
#RequestMapping(method = RequestMethod.GET)
public ModelAndView helloWorld(){
ModelAndView model = new ModelAndView("HelloWorldPage");
// first we need to give the countries list to the model
model.addObject("countries", countryService.getAllCountries());
// creating the form
ExampleForm form = new ExampleForm();
// setting the default to Germany (de)
form.setCountryCode = "de";
// adding the form (with the default country set) to the model
model.addObject("form", form);
return model;
}
In the JSP, we pass in the countries to the options and spring will automatically have germany selected:
<form:form method="post" commandName="form">
<%-- other fields ... --%>
<form:select path="countryCode">
<form:options items="${countries}" itemValue="countryCode" itemLabel="countryName"/>
</form:select>
<%-- other fields ... --%>
</form:form>
