'Encode List of Arrays as URL parameter

I have a RestController in SpringBoot that takes the same call as either a GET or a POST. One of the parameters is declared as: List<String[]>. I can work this as JSON in the POST just fine, but am having trouble trying to figure out how to represent it in a URL for a GET. There are solutions abound for a simple List<> or String[], but I haven't found anything for a List<String[]>.
