Spring boot Autowire issue

1. We are basically trying to achieve password change without restart of service as defined in https://blog.jdriven.com/2021/06/configure-hikari-connection-pool-when-using-rds-iam/
2. Implemented as shown below in the snippet
3. I have to call the Custom Datasource with new keyword as we have to create new connection as its Multitenant enabled service

serviceA bean is null in getPassword() method in CustomDatasource

@Service
public class CustomDatasource extends HikariDataSource {

@Autowired
private ServiceA serviceA;

 @Autowired
public CustomDatasource(HikariConfig hikariConfig) {
    super(hikariConfig);
}

 @Override
public String getPassword() {
   serviceA.someMethod();
}

}

@Service
public class HikariDataSourceBuilder {

CacheStore.getCache().setDataSource(new CustomDatasource(getHikariConfig(tenantId)).

public HikariConfig getHikariConfig(String tenant) {
return hikariConfig;
}
}

@Service
public class ServiceA {

public String someMethod() {
return "";
}
}

Options Tried

• Made CustomDatasource as @scope(scopeName = ConfigurableBeanFactory.SCOPE_PROTOTYPE), so that everytime new instance of the class is returned, and made changes to get the bean from Application context in HikariDataSourceBuilder.java class
• Tried few other options by defining Postcontruct in CustomDatasource and also by changing the way ServiceA set in CustomDatasource instance of the clas
