我下面Vault Configuration的例子来自：https ://spring.io/guides/gs/vault-config/ 。当我执行代码时，我遇到了错误。
错误：
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'vaultPropertySourceLocator' defined in class path resource [org/springframework/cloud/vault/config/VaultBootstrapPropertySourceConfiguration.class]: Unsatisfied dependency expressed through method 'vaultPropertySourceLocator' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'vaultTemplate' defined in class path resource [org/springframework/cloud/vault/config/VaultBootstrapConfiguration.class]: Unsatisfied dependency expressed through method 'vaultTemplate' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'vaultSessionManager' defined in class path resource [org/springframework/cloud/vault/config/VaultBootstrapConfiguration.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/VaultBootstrapConfiguration.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
