Spring Boot: Use database and application.properties for configuration

Question

I need to save the configuration of the Spring Boot application in the database.

Is it possible to store the database information in the application.properties

Answer 1

One possible solution that you could workout, is to use ConfigurableEnvironment and reload and add properties.

@Configuration   
public class ConfigurationPropertySource {

private ConfigurableEnvironment env;

private final ConfigurationRepository configurationRepository;

    @Autowired
    public ConfigurationPropertySource(ConfigurationRepository configurationRepository) {
        this.configurationRepository = configurationRepository;
    }

    @Autowired
    public void setConfigurableEnvironment(ConfigurableEnvironment env) {

        this.env = env;
   }

   @PostConstruct
   public void init() {
    MutablePropertySources propertySources = env.getPropertySources();
       Map myMap = new HashMap();
       //from configurationRepository get values and fill mapp
       propertySources.addFirst(new MapPropertySource("MY_MAP", myMap));
   }

}
