🔧 配置

这里以阿里云 OSS 为例,pom.xml 引入本项目,这里默认是 SpringBoot 环境,Solon 环境参考 在 Solon 中使用,其它环境参考 脱离 SpringBoot 单独使用

<!-- 引入本项目 -->
<dependency>
    <groupId>org.dromara.x-file-storage</groupId>
    <artifactId>x-file-storage-spring</artifactId>
    <version>2.2.1</version>
</dependency>
<!-- 引入 阿里云 OSS SDK,如果使用其它存储平台,就引入对应的 SDK  -->
<dependency>
    <groupId>com.aliyun.oss</groupId>
    <artifactId>aliyun-sdk-oss</artifactId>
    <version>3.16.1</version>
</dependency>

application.yml 配置文件中添加以下基础配置

关于配置文件及 FileInfo 中各种路径(path)的区别,可以参考 常见问题

dromara:
  x-file-storage: #文件存储配置
    default-platform: aliyun-oss-1 #默认使用的存储平台
    aliyun-oss:
      - platform: aliyun-oss-1 # 存储平台标识
        enable-storage: true  # 启用存储
        access-key: ??
        secret-key: ??
        end-point: ??
        bucket-name: ??
        domain: ?? # 访问域名,注意“/”结尾,例如:https://abc.oss-cn-shanghai.aliyuncs.com/
        base-path: test/ # 基础路径

🔨编码

在启动类上加上@EnableFileStorage注解

@EnableFileStorage
@SpringBootApplication
public class SpringFileStorageTestApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringFileStorageTestApplication.class,args);
    }

}

✨开始上传

支持 File、MultipartFile、UploadedFile、byte[]、InputStream、URL、URI、String、HttpServletRequest,大文件会自动分片上传。如果想支持更多方式,请阅读 文件适配器 章节

@RestController
public class FileDetailController {

    @Autowired
    private FileStorageService fileStorageService;//注入实列

    /**
     * 上传文件
     */
    @PostMapping("/upload")
    public FileInfo upload(MultipartFile file) {
        //只需要这一行代码即可上传成功
        return fileStorageService.of(file).upload();
    }
    
    /**
     * 上传文件,成功返回文件 url
     */
    @PostMapping("/upload2")
    public String upload2(MultipartFile file) {
        FileInfo fileInfo = fileStorageService.of(file)
                .setPath("upload/") //保存到相对路径下,为了方便管理,不需要可以不写
                .setSaveFilename("image.jpg") //设置保存的文件名,不需要可以不写,会随机生成
                .setObjectId("0")   //关联对象id,为了方便管理,不需要可以不写
                .setObjectType("0") //关联对象类型,为了方便管理,不需要可以不写
                .putAttr("role","admin") //保存一些属性,可以在切面、保存上传记录、自定义存储平台等地方获取使用,不需要可以不写
                .upload();  //将文件上传到对应地方
        return fileInfo == null ? "上传失败!" : fileInfo.getUrl();
    }

    /**
     * 上传图片,成功返回文件信息
     * 图片处理使用的是 https://github.com/coobird/thumbnailator
     */
    @PostMapping("/upload-image")
    public FileInfo uploadImage(MultipartFile file) {
        return fileStorageService.of(file)
                .image(img -> img.size(1000,1000))  //将图片大小调整到 1000*1000
                .thumbnail(th -> th.size(200,200))  //再生成一张 200*200 的缩略图
                .upload();
    }

    /**
     * 上传文件到指定存储平台,成功返回文件信息
     */
    @PostMapping("/upload-platform")
    public FileInfo uploadPlatform(MultipartFile file) {
        return fileStorageService.of(file)
                .setPlatform("aliyun-oss-1")    //使用指定的存储平台
                .upload();
    }

    /**
     * 直接读取 HttpServletRequest 中的文件进行上传,成功返回文件信息
     * 使用这种方式有些注意事项,请查看文档 基础功能-上传 章节
     */
    @PostMapping("/upload-request")
    public FileInfo uploadPlatform(HttpServletRequest request) {
        return fileStorageService.of(request).upload();
    }
}

🎨其它操作

//手动构造文件信息,可用于其它操作
FileInfo fileInfo = new FileInfo()
        .setPlatform("huawei-obs-1")
        .setBasePath("test/")
        .setPath("aa/")
        .setFilename("image.png")
        .setThFilename("image.png.min.jpg");

//文件是否存在
boolean exists = fileStorageService.exists(fileInfo);
//下载
byte[] bytes = fileStorageService.download(fileInfo).bytes();
//删除
fileStorageService.delete(fileInfo);
//其它更多操作

如果将文件记录保存到数据库中,还可以更方便的根据 URL 进行操作了,详情请阅读 保存上传记录 章节

//直接从数据库中获取 FileInfo 对象,更加方便执行其它操作
FileInfo fileInfo = fileStorageService.getFileInfoByUrl("https://abc.def.com/test/aa/image.png");

//文件是否存在
boolean exists = fileStorageService.exists("https://abc.def.com/test/aa/image.png");
//下载
byte[] bytes = fileStorageService.download("https://abc.def.com/test/aa/image.png").bytes();
//删除
fileStorageService.delete("https://abc.def.com/test/aa/image.png");
//其它更多操作

🏗️添砖加瓦

🎋分支说明

X File Storage 的源码分为两个分支,功能如下:

分支 作用
main 主分支,release 版本使用的分支,与中央库提交的 jar 一致,不接收任何 pr 或修改
dev 开发分支,接受修改或 pr

🐞提供bug反馈或建议

提交问题反馈请说明正在 X File Storage 版本、相关依赖库版本、配置参数及问题代码

Gitee issue
GitHub issue

🧬贡献代码的步骤

  1. 在 Gitee 或者 Github 上 fork 项目到自己的 repo
  2. 把 fork 过去的项目也就是你的项目 clone 到你的本地
  3. 修改代码(记得一定要修改 dev 分支)
  4. commit后push到自己的库( dev 分支)
  5. 登录 Gitee 或 Github 在你首页可以看到一个 pull request 按钮,点击它,填写一些说明信息,然后提交即可
  6. 等待维护者合并

🧬 开发约定 & 配置

  1. JDK 11+、Maven 3.8.1+
  2. 代码风格,目前代码风格通过 spotless-maven-plugin + palantir-java-format 统一控制,Maven 构建时统一格式化代码
  3. 在开发阶段,IDE 要识别到 spotless-maven-plugin + palantir-java-format 需要安装插件:palantir-java-format

📐PR遵照的原则

欢迎任何人为 X File Storage 添砖加瓦,贡献代码,为了易用性和可维护性,需要提交的 pr(pull request)符合一些规范,规范如下:

  1. 逻辑清晰、注释完备,不易理解的代码段的说明等信息,必要时请添加单元测试,如果愿意,也可以加上你的大名
  2. 提交到 dev 分支,main 分支不接受任何 pr 或修改
  3. 如果我们关闭了你的 issues 或者 pr 请查看回复内容,我们会在回复中做出解释
