Annotation Type VaultPropertySource

@Target(value=TYPE)
 @Retention(value=RUNTIME)
 @Documented
 @Repeatable(value=VaultPropertySources.class)
 @Import(value=org.springframework.vault.annotation.VaultPropertySourceRegistrar.class)
public @interface VaultPropertySource

Annotation providing a convenient and declarative mechanism for adding a VaultPropertySource to Spring's Environment. To be used in conjunction with @Configuration classes.

Example usage

Given a Vault path secret/my-application containing the configuration data pair database.password=mysecretpassword, the following @Configuration class uses @VaultPropertySource to contribute secret/my-application to the Environment's set of PropertySources.

 @Configuration
 @VaultPropertySource("secret/my-application")
 public class AppConfig {

        @Autowired
        Environment env;

        @Bean
        public TestBean testBean() {
                TestBean testBean = new TestBean();
                testBean.setPassword(env.getProperty("database.password"));
                return testBean;
        }
 }
 

Notice that the Environment object is @Autowired into the configuration class and then used when populating the TestBean object. Given the configuration above, a call to testBean.getPassword() will return "mysecretpassword".

In certain situations, it may not be possible or practical to tightly control property source ordering when using @VaultPropertySource annotations. For example, if the @Configuration classes above were registered via component-scanning, the ordering is difficult to predict. In such cases - and if overriding is important - it is recommended that the user fall back to using the programmatic PropertySource API. See ConfigurableEnvironment and MutablePropertySources javadocs for details.

Element Detail

value

public abstract String[] value

Indicate the Vault path(s) of the properties to be retrieved. For example, "secret/myapp" or "secret/my-application/profile".

Each location will be added to the enclosing Environment as its own property source, and in the order declared.

propertyNamePrefix

public abstract String propertyNamePrefix

Property name prefix for properties obtained from Vault. All properties will be prefixed with propertyNamePrefix.

Default:

""

vaultTemplateRef

public abstract String vaultTemplateRef

Configure the name of the VaultTemplate bean to be used with the property sources.

Default:

"vaultTemplate"

renewal

public abstract VaultPropertySource.Renewal renewal

Configure lease renewal/rotation.

Default:

org.springframework.vault.annotation.VaultPropertySource.Renewal.OFF
