启动报错：
Description:
Field ossClient in com.rymall.file.service.OssSysFileServiceImpl required a bean of type ‘com.aliyun.oss.OSSClient’ that could not be found.
The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type ‘com.aliyun.oss.OSSClient’ in your configuration.
Process finished with exit code 1

github OSS中的ISSUE

解决方案：

  @Autowired
private OSSClient ossClient;
应该改为

	@Autowired
	private OSS ossClient;

Oss endpoint can’t be empty.

启动配置正确写法

注意图片配置alibaba是父节点
