Class VaultConfigDataLocationResolver

java.lang.Object

org.springframework.cloud.vault.config.VaultConfigDataLocationResolver

All Implemented Interfaces:

org.springframework.boot.context.config.ConfigDataLocationResolver<VaultConfigLocation>

public class VaultConfigDataLocationResolver
extends Object
implements org.springframework.boot.context.config.ConfigDataLocationResolver<VaultConfigLocation>

ConfigDataLocationResolver for Vault resolving VaultConfigLocation using the vault: prefix.

Resolution considers contextual locations as we as default locations. Contextual locations such as vault:secret/my-application are considered to be context paths for the Key-Value secrets backend. Using a default location vault: imports all enabled secret backends by creating SecretBackendMetadata from SecretBackendMetadataFactory. Note that both types,VaultSecretBackendDescriptor and SecretBackendMetadataFactory are resolved through spring.factories to allow optional presence/absence on the class path.

Mixing paths (spring.config.import=vault:,vault:secret/my-application,vault:secret/other-location) is possible as each config location creates an individual VaultConfigLocation. By enabling/disabling a VaultSecretBackendDescriptor, you can control the amount of secret backends that are imported through the default location.

You can customize the default location capabilities by registering VaultConfigurer in the BootstrapRegistry. For example:

 VaultConfigurer configurer = …;
 SpringApplication application = …;

 application.addBootstrapper(registy -> register(VaultConfigurer.class, context -> configurer));
 

Registers also VaultProperties in the BootstrapRegistry that is required later on by VaultConfigDataLoader.
