圖片上傳及獲取

圖片上傳

使用MultipartFile上傳圖片到tomcat的webapps目錄pic下面

public JsonResult saveImageFile(@RequestParam(value = "imageFile", required = false) MultipartFile imageFile, @RequestParam(value = "fileName", required = false) String fileName, HttpServletRequest request) {
    result = new JsonResult();
    try {
        //image輸出地址
        //String picPath = "/data/sdwan/apache-tomcat-8.5.32/webapps/pic/";
       // String picPath = request.getSession().getServletContext().getRealPath("upload/");//本地項目路徑
        //String photoFileName = imageFile.getOriginalFilename();
        File file=new File("");
        String picPath=file.getAbsolutePath().replace("bin","webapps\\pic\\");
        File newFile = new File(picPath+fileName);
        // 文件存在
        if (!newFile.exists()) {
            logger.info( picPath+"  targetFile is not exist");
            // 新建文件目錄
            newFile.mkdirs();
        }
        imageFile.transferTo(newFile);  //保存文件
        result.setRetCode("200");
        result.setRetMessage("圖片上傳成功!");

    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        result.setRetCode("400");
        result.setRetMessage("圖片上傳失敗!");
    } catch (IOException e) {
        e.printStackTrace();
        result.setRetCode("400");
        result.setRetMessage("圖片上傳失敗!");
    }

    return result;
}

 

圖片的獲取:http://localhost:8080/sdwan/pic/1560160595232kbq0s85qqta.jpg

在tomcat設置url虛擬路徑映射：server.xml

<Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
      <Context docBase="D:\Tomcat\webapps\pic" path="/sdwan/pic" reloadable="true"/>
    
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"

              pattern="%h %l %u %t &quot;%r&quot; %s %b" />                     

      </Host>
