I want to change application.properties values when my Spring Boot application is loaded. I want to change below properties when application is loaded.
From
spring.datasource.username=root
spring.datasource.password=encrypted password
To
spring.datasource.username=root
spring.datasource.password=XYZ //decrypted password
Password will be stored in encrypted form and when application is loaded, I would like to decrypt and set decrypted password.
I'm able to get application properties values, but how to modify it and set back
@Bean
ApplicationRunner applicationRunner(Environment environment) {
return args -> {
System.out.println( environment.getProperty("spring.datasource.username"));
//how to set decrypted password here
};
}
