springboot集成fastdfs

1、配置pom.xml

	com.github.tobato
	fastdfs-client
	1.25.2-RELEASE

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

##这个一定要有，比较坑

spring.jmx.enabled=false

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);

	}

}

通过以上三步就能成功集成

以下是我封装的一些API，

有 上传文件，上传图片及缩略图，删除，装载路径

fastdfs官方提供的api中下载方法无法满足作者系统业务，因此没有采取，但是可以通过api拿到文件 http路径，再进行下载
