如何解决Spring Cloud Vault:令牌spring.cloud.vault.token不能为空
大家好
我创建了一个程序来使用 start.spring.io 测试保险库。我在 bootstap.properties 文件中像这样配置保险库:
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>

此外,Vault 开发服务器已使用以下命令预先设置:
vault server -dev
但是当我运行程序时,它出现以下错误:
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
但是保险库令牌是在 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 bootstrap.properties 文件在应用程序属性 文件被调用之前被调用,并且必须在其中设置令牌,但为什么保险库没有注意到它?
解决方法
在 Spring Boot 2.4 中,不推荐使用属性源的引导上下文初始化(bootstrap.yml、bootstrap.properties)。
