Spring Cloud Vault:令牌(Spring.Cloud.wulture.Token)不能为空

Question

大家好

我创建了一个程序，用start.spring.io测试vault。我在bootstap.properties文件中配置vault，如下所示：

spring.application.name=vault-test
spring.cloud.vault.uri=http://localhost:8200
spring.cloud.vault.token=MY_ROOT_TOKEN

这是我的pom.xml配置：

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.4.1</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
<java.version>15</java.version>
<spring-cloud.version>2020.0.0</spring-cloud.version>
</properties>
<dependencies>
<dependency>

</build>

</repository>
</repositories>

此外，vault开发服务器是用以下命令预先设置的：

vault server -dev

但当我运行该程序时，它会出现以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'vaultTemplate' defined in class path resource [org/springframework/cloud/vault/config/VaultAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.vault.core.VaultTemplate]: Factory method 'vaultTemplate' threw exception; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'vaultSessionManager' defined in class path resource [org/springframework/cloud/vault/config/VaultAutoConfiguration.class]: Unsatisfied dependency expressed through method 'vaultSessionManager' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'clientAuthentication' defined in class path resource [org/springframework/cloud/vault/config/VaultAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.vault.authentication.ClientAuthentication]: Factory method 'clientAuthentication' threw exception; nested exception is java.lang.IllegalArgumentException: Token (spring.cloud.vault.token) must not be empty

但是vault令牌是在bootstrap.properties文件中设置的！。但对我来说最奇怪的是，当我在application.properties文件中设置令牌时，我不会出错！我知道在调用应用程序属性文件之前会调用bootstrap.properties文件，并且必须在其中设置令牌，但vault为什么没有注意到呢？

使用Spring Boot 2.4，不赞成使用属性源的引导上下文初始化(bootstrap.yml，bootstrap.properties(。请参阅以下内容：

您似乎缺少spring-cloud-starter依赖项(如果您在start.spring.io.上选择Cloud Bootstrap依赖项，则应添加该依赖项

只需在pom.xml文件中添加以下依赖项：

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter</artifactId>
</dependency>
