在springboot项目中编写超级简单的用户头像上传与回显的接口_springboot用户管理头像图片好几个

废话不多说，直接上代码

@PostMapping("/upload")
    public ResponseResult upload(@RequestParam MultipartFile file){
        String path=System.getProperty("user.dir")+"/file/";
        String newFileName= UUID.randomUUID().toString().replaceAll("-","")+file.getOriginalFilename();
        File newFile=new File(path,newFileName);
        if (!newFile.getParentFile().exists()){
            newFile.getParentFile().mkdirs();
        }
        try {
            file.transferTo(newFile);
        } catch (IOException e) {
            e.printStackTrace();
            return new ResponseResult(201,"上传失败");
        }
        String filePath="/upload/"+newFileName;
        return new ResponseResult(200,"保存成功",filePath);
    }

在启动类中

@SpringBootApplication
public class WebApplication {
    public static void main(String[] args) {
        SpringApplication.run(WebApplication.class,args);
    }
    
    @Bean
    public WebMvcConfigurer webMvcConfigurerUpload(){
        String uploadPath=System.getProperty("user.dir")+"/file/";
        return new WebMvcConfigurer() {
            @Override
            public void addResourceHandlers(ResourceHandlerRegistry registry) {
                registry.addResourceHandler("/upload/**")
                        .addResourceLocations("file:"+uploadPath+"/");
            }
        };
    }
}
