Could not resolve placeholder 'XXX' in string value "${XXX}"

In my spring boot example, I'd like to read environment variables from my local machine(Win 7).

@Data
@Component
public class EnvironmentVariableSystemProperties {

  @Value("${java.home}")
  private String javaHome;

  @Value("${DATASTORE.DATASET}")
  private String datastoreDataset;

  @Value("${SPRINGA}")
  private String springConfigName;

}

It works well when reading java.home and DATASTORE.DATASET which have been added in my OS environment variables before. I just added a new variable SPRINGA. When running spring boot example, I got the error:

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'SPRINGA' in string value "${SPRINGA}".

Should I restart up my machine to make the variable work? I just restarted Eclipse, but it didn't work.

Restarting Eclipse with the Restart in the Menu doesn't work.
Exiting Eclipse and Running it again works.
How weird it is!
