使用SpringBoot设置虚拟路径映射绝对路径

目录

• SpringBoot 设置虚拟路径映射绝对路径
  • 下面我们就来代码实现下
• springboot打war包图片的虚拟路径映射
  • 在html图片的路径如图
  • 然后要映射到阿里云Linux服务器上路径
  • 映射方法
  • 在Host节点加上下面的
  • 这里顺便放上后台接收上传头像的代码

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
 
/**
 * 图片绝对地址与虚拟地址映射
 */
 
@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter { 
  @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) { 
//文件磁盘图片url 映射
//配置server虚拟路径，handler为前台访问的目录，locations为files相对应的本地路径
registry.addResourceHandler("/image/**").addResourceLocations("D:picpath");
  } 
}

@ResponseBody
    @RequestMapping("uploadImage")
    public DataGridView uploadImage(MultipartFile file, HttpSession session) throws Exception {
        DataGridView dataGridView = null;
        if (!file.isEmpty()){
            String filename = file.getOriginalFilename(); //abc.jpg
            String suffix = filename.substring(filename.lastIndexOf(".")); //后缀 如abc.jpg,就是jpg
            String newFileName = DateUtil.getCurrentDateStr() + suffix;  //新文件名
            FileUtils.copyInputStreamToFile(file.getInputStream(),new File(userImageFilePath+newFileName));
            Map<String,Object> map= new HashMap<>();
            map.put("src","/project/userImages/"+newFileName);
            map.put("title",newFileName);
            dataGridView = new DataGridView(0, "上传成功", map);
            User currentUser = (User) session.getAttribute("currentUser");
            currentUser.setImageName(newFileName);
            userService.save(currentUser);
            session.setAttribute("currentUser",currentUser);
            System.out.println("执行完了");
        }
        return dataGridView;
    }
