1、配置pom.xml

<dependency>
<groupId>com.github.tobato</groupId>
	<artifactId>fastdfs-client</artifactId>
	<version>1.25.2-RELEASE</version>
</dependency>

2、配置application.properties

fdfs.soTimeout=1500
fdfs.connectTimeout=600
fdfs.thumbImage.width=150
fdfs.thumbImage.height=200
fdfs.trackerList[0]=ip:port
 

fdfs.trackerList[1]=ip:port

##這個一定要有，比較坑

3、applicatio.java

引入 @Import(FdfsClientConfig.class)

@Import(FdfsClientConfig.class)
@SpringBootApplication
public class FileApplication {

	public static void main(String[] args) {

		SpringApplication.run(FileApplication.class, args);

	}

}
 

通過以上三步就能成功整合

以下是我封裝的一些API，

有 上傳檔案，上傳圖片及縮圖，刪除，裝載路徑

fastdfs官方提供的api中下載方法無法滿足作者系統業務，因此沒有采取，但是可以通過api拿到檔案 http路徑，再進行下載
