How do I pass an array to a Spring controller method with jquery ajax

Question

Here\'s my ajax call:

 $.ajax({
     type: \'GET\',
     url: contextPath + \'/test/location\',
     data: {\'objectValues\': object.objectValues },
     datatyp

Try changing your RequestParam annotation value to this:

@RequestParam(value="objectValues[]", required=false)

If this solves the problem, then it is due to a parameter naming incompatibility between Spring and jQuery, where jQuery wants to put square brackets in to indicate that a parameter is an array (I think PHP likes this too), but where Spring doesn't care. To see the reverse try setting the "data" parameter of the ajax request to the string: 'objectValues=1234567890&objectValues=0987654321'
