I am trying to set variiable throw SpEL in spring boot application:

@Value("${data.jndi-name:#{null}}")
private String jndiDataSource;
data.jndi-name should comes from application-{profile}.properties. But field jndiDataSource always null even if data.jndi-name exists.
Code with @Value("${data.jndi-name}") work fine but jndiDataSource contains empty string.
My question is how to set null to variable if property does not exists using SpEL.
upd: values comes from profile specific property file
                This work well only when data comes from main application.properties. When data comes from profile profile specific property it's not work
