Я havent прочитал ваш полный вопрос, но AJAX не может использоваться для загрузки файлов. – vinay

Я хочу знать альтернативные варианты загрузки файла в трикотаж. –

Замените код Ajax фактической формой отправки, если перезагрузка/перенаправление страницы в порядке или использование скрытого iframe, если перегрузка/перенаправление страницы нежелательно. – vinay

try this may work for you 

$.ajax({ 
        type: "POST", 
        url: 'http://localhost:8080/IDNS_Rule_Configuration/idns/idnsData/importYaml', 
        enctype: "multipart/form-data", 
        data: formData, 
        processData: false, 
        contentType: false, 
        success: function (data) { 
    //some success functions 
    } 
    });
