Spring CommonsMultipartResolver 上傳文件

轉：http://yanglei008.iteye.com/blog/246920

 

  
 ...Controller...{
    
    // 創建一個通用的多部分解析器
    CommonsMultipartResolver commonsMultipartResolver = 
new CommonsMultipartResolver(request.getSession().getServletContext());
    // 設置編碼
    commonsMultipartResolver.setDefaultEncoding("utf-8");
    // 判斷 request 是否有文件上傳,即多部分請求...
    if (commonsMultipartResolver.isMultipart(request))
    {
        // 轉換成多部分request
        MultipartHttpServletRequest multipartRequest = commonsMultipartResolver.resolveMultipart(request);

        // file 是指 文件上傳標簽的 name=值
        // 根據 name 獲取上傳的文件...
        MultipartFile file = multipartRequest.getFile("file");

        // 上傳后記錄的文件...   
        File imageFile = new File("fileName");
        // 上傳...
        file.transferTo(imageFile);

        // to do
    }
}

 

也可以在Spring配置文件中配置

Xml代碼

    <property name="defaultEncoding" value="UTF-8" />
</bean>
