2.SpringBoot集成

Java Quickstart Guide https://min.io/docs/minio/linux/developers/java/minio-java.html#minio-java-quickstart

Java SDK https://github.com/minio/minio-java/tree/release

2.1 依赖及配置

dependency>
    groupId>io.miniogroupId>
    artifactId>minioartifactId>
    version>8.5.5version>
dependency>

在Minio Console上生成的两个 Key：

{
    "accessKey": "SllF5SkIozb1n0b1D84M",
    "api": "s3v4",
    "path": "auto",
    "secretKey": "ZQSiCm3UDST1Q5lL1sImpOUNKIQSv6qZGucB4ku0",
    "url": "http://tcloud:9090/api/v1/service-account-credentials"
}

yml配置：

minio:
  url: http://tcloud:9000
  accessKey: SllF5SkIozb1n0b1D84M
  secretKey: ZQSiCm3UDST1Q5lL1sImpOUNKIQSv6qZGucB4ku0
