springboot 上傳文件 圖片 前後分離

1.application.properties

#上傳文件大小限制spring.servlet.multipart.max-file-size=500MBspring.servlet.multipart.max-request-size=500MB

2.前端

 //上傳
    	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);	        //發送 post 請求提交保存
	        $.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:'上傳成功',                	            bg:'#AE81FF',                	            time:2
                	        });
	                    	setTimeout(function(){
	                    		top.Dialog.close();//關閉彈窗
	                        },1000);
	                    }else if("error" == data.result){
	                    	alert("上傳失敗,文件內容不能爲空!");
	                    	$("#showform").show();
	                		$("#jiazai").hide();
	                    }else if ("exception" == data.result){
	                    	alert("文件管理"+data.exception);//顯示異常
	                    	$("#showform").show();
	                		$("#jiazai").hide();
	                    }
	                }
				})
    	},
