Enum values as dropdown list

Question

I am facing an issue populating a dropdown list from Enum class values. My enum class code is:

package abc.xyz.constants;

public enum StateConstantsEnum
{
           NEWYORK("NY"), 
            FLORIDA("FL"), 
            CALIFORNIA("CA"), 

    private String fullState;

    private StateConstantsEnum( String s )
    {
        fullState = s;
    }

    public String getState()
    {
        return fullState;
    }
}

I want populate dropdown list with NEWYORK, FLORIDA and CALIFORNIA. I am creating and adding the list to Spring model this way:

List<StateConstantsEnum> stateList = new ArrayList<StateConstantsEnum>( Arrays.asList(StateConstantsEnum.values() ));

model.addAttribute("stateList", stateList);

Then I am trying to populate the dropdown in JSP using:

<select name="${status.expression}" name="stateLst" id="stateLst">
    <option value=""></option>
        <c:forEach items="${stateList}" var="option">
                <option value="${option}">
                    <c:out value="${option.fullState}"></c:out>
                </option>
        </c:forEach>
</select>

But I am getting an exception "Exception created : javax.el.PropertyNotFoundException: The class 'abc.xyz.constants.StateConstantsEnum' does not have the property 'fullState'."

How do I fix this problem? Help much appreciated

Answer 1

fullState is private, getState() is the accessor.

<c:out value="${option.state}"></c:out>

Or rename your getter to getFullstate().

I think <c:out value="${option.state}"></c:out> would be correct. – Magdala

Oops.. I missed out on a small piece. Thanks. One more problem, this is printing NY, FL, CA, not NEWYORK, FLORIDA and CALIFORNIA. Any idea? – Underpants

Just use ${option} then. Actually, the "fullstate" name is misleading. It's the other way round. It holds a state abbreviation. – Roundworm

Thanks for the help and suggestion BalusC. I'll change it. – Underpants

Answer 2

in your JSP you can use a like that :

<form:select path="*">
  <form:options items="${stateList}" itemLabel="fullState"  />
</form:select>

it will extract all element in your liste (stateList) and if you dont specify an itemLabel and itemValue, it'll take your enums values of course you have to set your getter to getFullState,and declare springmvc tags in your page
