将应用程序推送到具有Microsoft Azure依赖项的PCF云时出现Nullpointer异常

我们正在使用Microsoft Azure存储文件，并使用com.Microsoft.Azure:Azure存储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

它在堆栈下推入PCF时给出NullPointerException

我建议查看以下博客： 作者解释了发生

NullPointerException

的可能原因

让我们来考虑一个有报酬美元的例子：

T=零

我们在这里到底是什么意思？“null”是T的类型还是其子类型？这是一段有效的代码，就像键入下面的内容并期望编译器为我们工作一样

T；//编译器强迫我赋值，嗯

现在，变量“t”只是一个引用，没有任何对象“Null”只是明确支持该约定。访问“T”的任何属性都会使编译器抛出著名的“NullPointerException”

今天我遇到了这个问题，我检查了git存储库中的最新代码。它已在版本“com.microsoft.azure:azure storage spring boot starter:2.0.2”中修复。

请尝试使用它。

嗨，arjun，如果您不想将spring boot版本提高到2.0，请在您的项目中使用denpency“com.microsoft.azure:azure storage”而不是“com.microsoft.azure:azure storage spring boot starter”。它在PCF平台中对我适用。
