我正在尝试使用spring和hibernate技术在我的freemarker页面(ftl文件)中添加图片上传 - 这是我每次运行应用程序时出现的错误:
HTTP状态500 - 服务器 遇到内部错误() 阻止它实现这一目标 请求。
这是代码:
1-POM文件:
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-io</artifactId>
<version>1.3.2</version>
</dependency>
2-app-config.xml:
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>
3英尺文件:
<input type="file" id="image" name="image" value="">
4-web controller:
@RequestMapping(method= RequestMethod.POST)
public String post(Model model , HttpServletRequest req , HttpSession session,@RequestParam("image") MultipartFile multipartFile) throws IOException{
// transfer the uploaded image to the place where images exist in project
multipartFile.getBytes();
File destination = new File("/home/user/Pictures/" + multipartFile.getOriginalFilename());
multipartFile.transferTo(destination);
// delete the original uploaded image
destination.delete();
return "redirect:index";
}
答案 0 :(得分:1)
务必按照Documentation的字母进行操作。通常,您是否正确定义了<form>
元素及其enctype
属性?
<form method="post" action="/form" enctype="multipart/form-data">
有关更多提示,需要日志,正如其他评论已经说过的那样。如果没有写入特定日志,请务必将记录器的阈值配置为较低级别;虽然500代码应该与ERROR级别的日志相关,但很少被过滤掉。仔细检查您的日志配置! :)
