java.security.InvalidAlgorithmParameterException 而 jClouds MS Azure Blob 放置操作答案

【问题描述】：

我在 jClouds AzureBlob API 中遇到了 put 操作的问题

context = new BlobStoreContextFactory().createContext(
                    this.storageType,
                    this.storageAccount, 
                    this.primaryAccessKey);

    BlobStore blobStore = context.getBlobStore();
                Blob blob = blobStore.blobBuilder(fileName).payload(content).build(); //$NON-NLS-1$
                blobStore.putBlob(this.containerName, blob);

我正在从管理访问密钥设置主访问密钥 -> 我的存储帐户的主访问密钥。

它给了我以下错误

在上面的堆栈跟踪中，“ERROR/error_20130717022518962.xml”是我试图放在 blob 存储中的文件。

任何线索，如何解决这个问题？

【问题讨论】：

我知道，这可能是 1. 信任库尚未设置或无法访问。但问题是这几个月以来一直有效，但突然开始出错。环境或代码没有变化。因此，请帮助我

标签： java azure-blob-storage jclouds

【解决方案1】：

此问题已解决，实际上是调用 ReST PUT 以进行 azure blob 存储的代码。不知何故无法加载 java 默认信任库。

通过添加下面的行来加载默认的 cacert

System.setProperty("javax.net.ssl.trustStore",PATH_TO_CACERT);
System.setProperty("javax.net.ssl.trustStorePassword",PASSWORD);
