spring boot配置从yml中读取文件

1.配置阿里云读取

1.1 配置yml

#阿里云上传相关配置
aliyun:
  ossclients:
    endPoint: "http://oss-cn-beijing.aliyuncs.com"     # 文件上传url
    accessKeyId: "LTAICLj4NJlxNRkD"                    # 上传ID
    accessKeySecret: "lMeJOF0JGVktsVS6AeBUxNG9KgOiQx"  # 秘钥
    bucketName: "scbookimg"                            # 实例name
    key: "imagefind/"                                  # 文件文件夹
    imgName: "img"                                     # 文件前缀 标识是图片还是视频（自己加的）

2.1 读取

2.1.1 从实体类读取

@Component  // 表示这是个bean需要注入
@Data
@ConfigurationProperties(value = "aliyun.ossclients") // yml对应的位置
public class OSSClientConfig {
    public String endPoint;
    public String accessKeyId;
    public String accessKeySecret;
    public String bucketName;
    public String key;
    public String imgName;
}

2.1.2 从代码中读取

    @Value("${aliyun.ossclients.endPoint}")
    public String endPoint;

3.1 调用

 @Autowired
    private OSSClientConfig ossClientConfig;
    @Test
    public void text2(){
        System.out.println(ossClientConfig);
    }
//OSSClientConfig(endPoint=http://oss-cn-beijing.aliyuncs.com, accessKeyId=LTAICLj4NJlxNRkD,
                accessKeySecret=lMeJOF0JGVktsVS6AeBUxNG9KgOiQx, bucketName=scbookimg,
                key=imagefind/, imgName=img)
