springboot 上传文件 前后分离

1.application.properties

#上传文件大小限制
spring.servlet.multipart.max-file-size=500MB
spring.servlet.multipart.max-request-size=500MB

2.前端

 //上传
    	uploadServer: function (){

            todata.append("FFILE", fhFile);
            todata.append("PARENT_ID", this.PARENT_ID);
            todata.append("NAME", this.pd.NAME);
            todata.append("REMARKS", this.pd.REMARKS);
            todata.append("SHARE", this.SHARE);
        //发送 post 请求提交保存
        $.ajax({
            	xhrFields: {
                    withCredentials: true
                },
url: httpurl+'mfolder/upload',
type: 'POST',  
                data: todata,  
                async: false,  
                cache: false,  
                contentType: false,  
                processData: false,
success: function(data){
                    if("success" == data.result){
                    	$("#fok").tips({
                				side:2,
                	            msg:'上传成功',
                	            bg:'#AE81FF',
                	            time:2
                	        });
                    	setTimeout(function(){
                    		top.Dialog.close();//关闭弹窗
                        },1000);
                    }else if("error" == data.result){
                    	alert("上传失败,文件内容不能为空!");
                    	$("#showform").show();
                		$("#jiazai").hide();
                    }else if ("exception" == data.result){
                    	alert("文件管理"+data.exception);//显示异常
                    	$("#showform").show();
                		$("#jiazai").hide();
                    }
                }
})
    	},
