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.
