FastDFS基本操作

引用

* clone该项目

* 执行：mvn clean install -Dmaven.test.skip 打成jar包

* 直接引用：
    <dependency>
        <groupId>fastdfs-api</groupId>
        <artifactId>fastdfs-api</artifactId>
        <version>1.2</version>
    </dependency>

用法

* 复制项目中的文件`fastdfs.properties`到自己的项目中

* 新建一个配置类
    @Component
    @RefreshScope
    @Configuration
    @ConfigurationProperties(prefix = "fastdfs")
    public class FastDFSBeanConfig {

        @Value("${es_file_server_addr}")

* 实例化FastDFSDefault
    @Autowired
    private FastDFSDefault fastDFSDefault;
    
* 文件上传
    @RequestMapping(value = "/common/upload")
    public String upload(){
        File file = new File("F:\\PIC\\images\\20180605185415_YKhlw.jpeg");
        FastDFSResponse fastDFSResponse = fastDFSDefault.upload(file,"F:\\PIC\\images\\20180605185415_YKhlw.jpeg", new HashMap<>());
        return JSON.toJSONString(fastDFSResponse);
    }
    
* 文件下载
    @RequestMapping(value = "/common/download")
    public String download(@RequestParam String fp){
        FastDFSResponse fastDFSResponse = fastDFSDefault.download(fp,"C:\\Users\\Shinelon\\Desktop\\");
        return JSON.toJSONString(fastDFSResponse);
    }
    
* 文件删除
    @RequestMapping(value = "/common/delete")
    public String delete(@RequestParam String fp){
        FastDFSResponse fastDFSResponse = fastDFSDefault.delete(fp);
        return JSON.toJSONString(fastDFSResponse);
