SpringMVC上传文件(图片)并保存到本地
小记一波~
基本的MVC配置就不展示了,这里给出核心代码
在spring-mvc的配置文件中写入如下配置
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize">
<value>100000</value>
</property>
<property name="defaultEncoding">
<value>UTF-8</value>
</property>
</bean>
接口
@RequestMapping(value="/uploadPictures",method=RequestMethod.POST)
public Object uploadHeadPic(@RequestParam("file")CommonsMultipartFile file,InputStream inputStream,HttpServletRequest request) {
String uuid = UUID.randomUUID().toString().trim();
String fileN=file.getOriginalFilename();
int index=fileN.indexOf(".");
String fileName=uuid+fileN.substring(index);
try {
File fileMkdir=new File("F:\\photoTest"); if(!fileMkdir.exists()) {
fileMkdir.mkdir();
}
//定义输出流 将文件保存在D盘 file.getOriginalFilename()为获得文件的名字
FileOutputStream os = new FileOutputStream(fileMkdir.getPath()+"\\"+fileName);
InputStream in = file.getInputStream();
int b = 0;
while((b=in.read())!=-1){ //读取文件
os.write(b);
}
os.flush(); //关闭流
in.close();
os.close();
} catch (Exception e) {
return ActionHelper.responseFailed("上传失败!");
}
return ActionHelper.responseOk(fileName);
}
ActionHelper为我自己封装的工具类,这里根据业务替换成自己需要的即可
