How to check date format in spring form

I'm new to Spring, and I'm trying to create a form that checks the date format (that is: it only accepts dates with the format " MM/dd/yyyy", if the user puts " mm-dd-yyyy", it should show an error message).

How can I achieve this with Spring?

I read a lot of messages and answers, such as this and which are recommended for use @InitBinderin the controller (I tried, but could not get it to work by the way). But what if I have a form with different dates? or if my controller manages multiple send requests from different forms, and each of them requires checking for different dates?

I currently have this form:

<form:form action="getReportFile.html" commandName="staticReportForm">
            <table>
                <tr>
                    <td>Reports:</td>
                </tr>
                <tr>
                    <td><form:select path="report" items="${staticReports}"/>                        
                    </td>
                </tr>
               <tr>
                   <td>Date (MM/DD/YYYY) (empty for most recent possible):<FONT color="red"><form:errors
                                path="date" /></FONT></td>
               </tr>
               <tr>
                   <td><form:input path="date" /></td>
               </tr>
               <tr>
                   <td><input type="submit" value="Submit" /></td>
               </tr>
           </table>            
       </form:form>

bean, ( @DateTimeFormat , ):

public class StaticReportForm {
        @NotEmpty        
        private String report;    
        @DateTimeFormat(pattern="MM/dd/yyyy")
        private Date date;

    public String getReport() {
        return report;
    }

    public void setReport(String report) {
        this.report = report;
    }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }
