Springboot 上传图片及访问

1、yml配置

下面的服务器根据自己所用的进行调整即可

upload:
  file:
    # 这是linux服务器的上传路径
    #    location: file:/mnt/www/pp/test_ai/image
    #这是windows服务器的上传路径
    location: file:d://image/
 #这是访问的虚拟路径
    path: /temp-image/**
fileServer:
#这是访问图片的服务
  url: http://localhost:9099/test_api

2、上传controller

此方法中ObjectResponse是本人自定义的返回类，大家可以根据自己的来进行编写。

@RequestMapping({"/file"})
@RestController
@CrossOrigin(origins = {"*"}, maxAge = 3600)
/* loaded from: CarouseImageController.class */
public class FileUploadController {
    @Value("${upload.file.location}")
    private String fileLocation;
    @Value("${upload.file.path}")
    private String filePath;
    @Value("${fileServer.url}")
    private String fileServer;
    

    @PostMapping({"/importPicture"})
    @ResponseBody
    @CrossOrigin(origins = {"*"})
    public ObjectResponse importPicture(@RequestParam("file") MultipartFile file) throws FileNotFoundException {
        String filename = UUID.randomUUID() + ((String) Objects.requireNonNull(file.getOriginalFilename())).substring(file.getOriginalFilename().lastIndexOf("."));
        File filepath = new File(this.fileLocation.replaceAll("file:", "") + filename);
        String.valueOf(filepath);
        try {
            file.transferTo(filepath);
            System.out.println("文件已存储成功，路径：" + filepath.getPath());
        } catch (IOException e) {
            e.printStackTrace();
        }
        return new ObjectResponse (Boolean.TRUE.booleanValue(), "操作成功！", (this.filePath + filename).replaceAll("\\*", ""));
    }

}

3、添加配置类（此类必须要有，不然是访问不了的）

@Configuration
public class ProjectWebMvcConfigurer implements WebMvcConfigurer {
    @Value("${upload.file.location}")
    private String fileLocation;
    @Value("${upload.file.path}")
    private String filePath;

    @Bean
    TokenInterceptor paramInterceptor() {
        return new TokenInterceptor();
    }

    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler(new String[]{"/static/**"}).addResourceLocations(new String[]{"classpath:/static/"});
        registry.addResourceHandler(new String[]{"/templates/**"}).addResourceLocations(new String[]{"classpath:/templates/"});
        registry.addResourceHandler(new String[]{this.filePath}).addResourceLocations(new String[]{this.fileLocation});
    }

    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(paramInterceptor()).addPathPatterns(new String[]{"/**"}).excludePathPatterns(new String[]{"/static/**"});
    }

    public void addCorsMappings(CorsRegistry registry) {
        System.out.println("----------------------");
        registry.addMapping("/**").allowedOrigins(new String[]{"*"}).allowCredentials(true).allowedMethods(new String[]{AdminCommonConstant.RESOURCE_REQUEST_METHOD_GET, AdminCommonConstant.RESOURCE_REQUEST_METHOD_POST, AdminCommonConstant.RESOURCE_REQUEST_METHOD_DELETE, AdminCommonConstant.RESOURCE_REQUEST_METHOD_PUT, "OPTIONS"}).maxAge(3600L);
    }
}
