我们使用 Microsoft Azure 存储文件并使用 com.microsoft.azure:azure-storage-spring-boot-starter 依赖项。连接 URL 可以很好地连接到 azure，并且应用程序在本地正常运行。

它在推入具有以下堆栈的 PCF 时给出 NullPointerException。

我今天遇到了这个问题，我检查了 git 存储库中的最新代码。它已在“com.microsoft.azure:azure-storage-spring-boot-starter:2.0.2”版本中修复。请尝试一下。

我建议查看以下博客：https ://dzone.com/articles/one-dollar-solution-to-avoid-null-pointer-exceptio 作者解释了NullPointerException发生这种情况的可能原因。

让我们考虑一个支付美元的例子：

T t = 空；

我们在这里的真正意思是什么？'null' 是 T 的类型还是它的子类型？它与输入下面的代码并期望编译器为我们工作一样有效。

吨; // 编译器强迫我分配，对吧？

现在，变量 't' 只是一个没有任何对象的引用。'Null' 只是明确支持该约定。访问“T”的任何属性都会使编译器产生著名的“NullPointerException”。
