Depending on how you initialized your app, but normally you would put something like 

@EnableAutoConfiguration
@PropertySource("classpath:application.properties")
@ComponentScan
@SpringBootApplication
@EnableTransactionManagement

Make sure you have one of these in your configs

@Bean
public static PropertySourcesPlaceholderConfigurer propertyPlaceholderConfigurer() {
    return new PropertySourcesPlaceholderConfigurer();
}

Then you can access values like this 

@Value("${datasource.username}")
@NotNull //optional
String username;
