引入相关bootstrap文件链接

编写前台代码

<#include "../common/header.ftl">
   
    <#include  "../common/nav.ftl">    <#--上传文件区域-->    
    
        
     
            
      
                
       
                    
        
 
         
 
          图片上传 
          
 
            
          
 
         
 
        
                
       
            
      
        
     
    
    
   

后台接收图片，并存入本地

@PostMapping("/uploadImages")@ResponseBodypublic String uploadImages(HttpServletRequest request,MultipartFile file){    try{        String filename = file.getOriginalFilename();        //上传的路径        String path = "d:\\upload";        filename = changeName(filename);        String rappendix = "upload/" + filename;        filename = path + "\\" + filename;        File file1 = new File(filename);        file.transferTo(file1);        String str = "{\"src\":\"" + rappendix + "\"}";        return str;    }catch (Exception e){        throw new AuthorizationException("上传文件失败");    }}

效果如下:
