FastDFS integrated springboot configuration and use

1 Environmental preparation

Resources	Remarks
FastDFS deployment environment	If not deployed, refer to the blog post FastDFS installation configuration and testing
IDEA2021	Development tools depend on your own preferences

The FastDFS deployment information I deployed here is:

server information	IP address
tracker server	192.168.51.5
storage server	192.168.51.6

2 pom file configuration

Create a new springboot project and introduce official fastdfs dependencies

<dependency>
		<groupId>com.github.tobato</groupId>
		<artifactId>fastdfs-client</artifactId>
		<version>1.26.7</version>
</dependency>

2 application file configuration
