Java MINIO使用踩坑&解决

 解决：

minio的官方文档有中英文两版，中文版的示例版本是7.0.2，英文版是8.3.0，如果是用docker直接pull的话，是最新版latest，pom文件引入依赖的时候要注意对应。

    io.minio
    minio
    8.3.0

并且 运行端口9000是api的端口和9001是网页版的端口。

docker run -p 9000:9000 -p 9001:9001 --name minio -v D:\data:/data -e "MINIO_ROOT_USER=user" -e "MINIO_ROOT_PASSWORD=password" minio/minio server /data --console-address ":9001"

即创建minioclient时要用9000，而http://localhost:9001/用于网页访问控制台。

MinioClient minioClient = MinioClient.builder()
                    .endpoint("http://localhost:9000/")
                    .credentials("user", "password")
                    .build();

2. Unsupported OkHttp library found. Must use okhttp >= 4.8.1

Exception in thread "main" java.lang.ExceptionInInitializerError
	at com.glorypan.console.utils.FileUploader.main(FileUploader.java:18)
Caused by: java.lang.RuntimeException: Unsupported OkHttp library found. Must use okhttp >= 4.8.1

	at io.minio.S3Base.(S3Base.java:105)

 解决：

minio依赖于okhttp，所以pom文件还需要引入一下okhttp。

    com.squareup.okhttp3
    okhttp
    4.9.0

解决：http别加s就行！ 

MinioClient minioClient = MinioClient.builder()
                    .endpoint("http://localhost:9000/")
                    .credentials("user", "password")
                    .build();
