ConstantPropertiesUtils:(用于注入配置文件中的阿里云配置信息)

OssApplication:

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@ComponentScan(basePackages = {"com.coderkun"}) //为了swagger扫描到该包下的Controller
public class OssApplication {public static void main(String[] args) {SpringApplication.run(OssApplication.class,args);}

OSSController：

@RestController

OssServiceImpl:
