This app showcases a bunch of different features.

DemoApplication.java declares a @EnableEncryptableProperties annotation that bootstraps jasypt-spring-boot declaratively and enables property encryption across the entire Spring Environment.

@EnableEncryptableProperties
public class DemoApplication {

}

DemoApplication.java declares a few @EncryptablePropertySource annotations that load encryption-capable property sources.

@EncryptablePropertySource(name = "EncryptedProperties2", value = "classpath:encrypted2.properties")
@EncryptablePropertySource(name = "EncryptedProperties3", value = "classpath:encrypted3.yml")
public class DemoApplication {

}

In this scenario is not strictly necessary since @EnableEncryptableProperties already decorates all property sources, so when using @EnableEncryptableProperties (Or the starter jar) you can load encryption-capable properties with Spring's @PropertySource annotation.

DemoApplication.java declares a @PropertySource annotations that loads an encryption-capable property source.

@PropertySource(name = "EncryptedProperties", value = "classpath:encrypted.properties")
public class DemoApplication {

}

As mentioned above, the fact that we're using @EnableEncryptableProperties, it already decorates all property sources, so when using @EnableEncryptableProperties (Or the starter jar) you can load encryption-capable properties with Spring's @PropertySource annotation.

DemoApplication.java declares a @EnableConfigurationProperties that allows ItemConfig to be populated from the environment.

jasypt-spring-boot works seamlessly with this annotation also so you can define your @ConfigurationProperties annotated classes that contain references to encrypted properties.

@EnableConfigurationProperties(ItemConfig.class)
public class DemoApplication {

}

DemoApplication.java declares a @ImportResource that allows testConfig.xml to be loaded.

jasypt-spring-boot works seamlessly with this annotation also so you can import your XML that contains references to encrypted properties.

@ImportResource("classpath:/testConfig.xml")
public class DemoApplication {

}

SimpleBean.java and MyService.java both use the @Value annotation to inject decrypted versions of the encrypted properties present on the configuration files.
