You are sending an Ajax request and you are using name of input field directly in your controllerwhich cause the problem. Because when ajax request come to the controller it doesn't found any parameter with name "uploadfile"that's why it giving you error.
您正在发送 Ajax 请求并you are using name of input field directly in your controller导致问题。因为当 ajax 请求到达时，controller it doesn't found any parameter with name "uploadfile"这就是它给你错误的原因。

enctype : 'multipart/form-data',
contentType : false,
cache : false,
processData : false,
success : function(response) {},
error: function(){}
)};

Java 控制器代码：，
