错误 Spring Boot 列出 Azure Blob 存储中的所有文件答案

【问题标题】：Error Sping Boot list all files in Azure Blob Storage错误 Spring Boot 列出 Azure Blob 存储中的所有文件
【发布时间】：2022-08-16 13:04:23
【问题描述】：

我试图在我的 Azure 容器中列出我的所有文件，但是当我使用方法 .listBlobs( ) 时，我无法获得我的 BlobItems 列表。

我收到错误：java.lang.NoSuchMethodError: reactor.core.publisher.Mono.mapNotNull(Ljava/util/function/Function;)Lreactor/core/publisher/Mono;

我的 BlobContainerClient 正在正确获取连接字符串和容器名称。

按照下面的代码：

public List<String> listFiles() {
    BlobContainerClient containerClient = containerClient();
    PagedIterable<BlobItem> blobItems = containerClient.listBlobs();
    List<String> list = new ArrayList<>();
    for (BlobItem item : blobItems) {
        list.add(item.getName());
    }

    return list;
}

如果有人遇到同样的问题，我会在这里发布。

我发现问题是我的弹簧靴版本因为我正在使用2.4.0当我从2.7.2这工作正常。
