azure spring启动程序keyvault机密在PCF中启动应用程序期间未解析vcap服务变量



我正在将我的应用程序从旧版本的azure密钥库升级到最新版本的azure-bom。

以下是pom.xml中的更改，并且应用程序无法在PCF 中启动

在pom.xml中进行更改之前：

<dependency>
<groupId>com.microsoft.azure</groupId>
<artifactId>azure-keyvault</artifactId>
<version>1.2.4</version>
</dependency>
<dependency>
<groupId>com.microsoft.azure</groupId>
<artifactId>azure-keyvault-secrets-spring-boot-starter</artifactId>
<scope>runtime</scope>
<version>2.1.3</version>
</dependency>
<dependency>
<groupId>com.microsoft.azure</groupId>
<artifactId>azure-storage</artifactId>
<version>5.5.0</version>
</dependency>

在pom.xml 中进行更改后


<dependency>
<groupId>com.azure.spring</groupId>
<artifactId>azure-spring-boot-starter-keyvault-secrets</artifactId>
</dependency>
.....
<dependencyManagement>
<dependency>
<groupId>com.azure.spring</groupId>
<artifactId>azure-spring-boot-bom</artifactId>
<version>3.5.0</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>

当使用旧版本时，该应用程序启动并能够读取

azure.keyvault.enabled=true
azure.keyvault.client-id=${vcap.services.myservice.credentials.clientId}
azure.keyvault.client-key=${vcap.services.myservice.credentials.clientKey}
azure.keyvault.uri=${vcap.services.myservice.credentials.uri}
azure.keyvault.tenant-id=1234567-1234-1234-1234-1234werewrew

应用程序启动时的属性

但在对pom.xml进行更改并获得以下异常后，同样的问题并没有得到解决

有什么变化打破了这个局面吗？

@VenuMadhav。

我试过使用azure-spring-boot-starter-keyvault-secrets:3.5.0和spring-boot:2.4.8，没有问题。所以我无法重现你的问题。

如果我直接在pcf中传递与环境属性相同的vcap变量，应用程序就会启动并正常工作。

你是说当你把vcap variables放在密钥库中时，应用程序就无法启动吗？

如果你的问题仍然存在，你能在github中创建一个简单的样本，它可以重现你的问题，并共享样本的链接吗？

最好通过github问题提问：https://github.com/Azure/azure-sdk-for-java/issues

最终我解决了问题

在我的application.properties文件中，很少有用camel大小写定义的属性，如下面的clientId和clientKey，这些都是导致问题的原因。

azure.keyvault.client-id=${vcap.services.myservice.credentials.clientId}
azure.keyvault.client-key=${vcap.services.myservice.credentials.clientKey}

在将占位符从驼色大小写改为小写后，该应用程序能够解析这些属性。我将占位符更改为以下

azure.keyvault.client-id=${vcap.services.myservice.credentials.clientid}
azure.keyvault.client-key=${vcap.services.myservice.credentials.clientkey}

注意：我没有在PCF服务绑定中更改为小写，它们仍然使用camel大小写。所以，看起来弹簧靴正在将所有密钥转换为小写
