Unable to update hikari datasource configuration in spring boot app - spring-boot

Question

Hikari datasource configurations always taking as default values. even though i provide the actual configurations in application.yml file.
MainApp.java
#SpringBootApplication
public class MainApp {
public static void main(String[] args) {
SpringApplication.run(MainApp.class, args);
}
#Bean
#Primary
public DataSourceProperties dataSourceProperties() {
return new DataSourceProperties();
}
//I use below method to set password from different approach instead of taking from app.yml
#Bean
public DataSource dataSource(DataSourceProperties properties) {
DataSource ds = properties.initializeDataSourceBuilder()
.password("setting a password from vault")
.build();
return ds;
}
}
application.yml
spring:
application:
name: demo
datasource:
hikari:
connection-timeout: 20000
minimum-idle: 5
maximum-pool-size: 12
idle-timeout: 300000
max-lifetime: 1200000
auto-commit: true
driverClassName: com.microsoft.sqlserver.jdbc.SQLServerDriver
url: jdbc:sqlserver://ip:port;databaseName=sample
username: username
Using Spring 2.1.1.RELEASE and when i start the application i logged the Hikari logs and it says all default values. So i did debugged on the second bean datasource and its actually HikariDatasource and except default values rest of them are empty and not reflecting the given values from the application.yml. Please recommend or comment if i misconfigured anything or done any mistake!
