Read key value from yaml file in spring boot

This is the third way to read the application.properties and most elegant way too. We can use this class getters and setters to fetch the property value from application.properties or application.yaml file, We have autowired the ConfigurationPropertyValues class and with the help of getter methods we are fetching the data from properties file. This tells Spring Boot to search for an application.properties or application.yml file in the current folder (which is the default) and to additionally load the file quotes.yml. This is all we need to do for Spring Boot to load our YAML file and expose the content within our application. Accessing the Static Data. Now to the code. So remove spring boot profile from properties or yaml or run app with enabled profile. Configuration file example is below: @Configuration public class AppConfig { @Value ("$. This tells Spring Boot to search for an application.properties or application.yml file in the current folder (which is the default) and to additionally load the file quotes.yml. This is all we need to do for Spring Boot to load our YAML file and expose the content within our application. Accessing the Static Data. Now to the code. Starting with Boot version 2.4.0, this is also possible for properties files. It's worth mentioning that Spring Boot provides out-of-the-box support for YAML configuration. By.
