用tomcat搭建图片服务器（SSM）

将图片上传到Tomcat中的upload中，外部通过URL访问

2.FileController

import java.util.HashMap;
import java.util.UUID;

@Controller
public class FileController {
    @Value("${netAddress}")
    private String host;
    //提交修改页面 入参  为 Items对象
    @ResponseBody
    @RequestMapping(value = "/updateitem.action",method = RequestMethod.POST)
    public Object updateitem(@RequestParam("myPhoto") MultipartFile pictureFile, HttpServletRequest request) throws Exception{
        System.out.println("asd");
        HashMap hashMap=new HashMap<>();
        ObjectMapper mapper = new ObjectMapper();
        try {
            if (pictureFile!=null){
                //保存图片到
                String name = UUID.randomUUID().toString().replaceAll("-", "");
                //jpg
                String ext = FilenameUtils.getExtension(pictureFile.getOriginalFilename());
                /**
                 * 　String path = request.getSession().getServletContext().getRealPath("/");
                 * path值如下：
                 * C:\develop\apache-tomcat-7.0.75\webapps\ROOT\
                 */
                String url = request.getSession().getServletContext().getRealPath("/upload");
                pictureFile.transferTo(new File(url+"/" + name + "." + ext));
                String pitureUrl=host+name + "." + ext;
                System.out.println(pitureUrl);
                hashMap.put("end","OK");
                hashMap.put("url",pitureUrl);
            }else {
                hashMap.put("end","do not find file---pictureFile is null");
            }


        }catch (Exception e){
            hashMap.put("end","upload err");
            e.printStackTrace();
        }

        System.out.println(hashMap.toString());
        return mapper.writeValueAsString(hashMap);
    }
}
