Simple setting of values.

    @Value("${prop.strName:default value}}")
    private String localDir;

    @Value("${prop.intName:14}}")
    private int localDir;

Apply a setting, defaulting to a subdirectory of the temporary folder.

    @Value("${prop.name:#{systemProperties['java.io.tmpdir']+'/subdir'}}")
    private String localDir;

When a value is not present in the application.properties file, assume null.

    @Value("${prop.name:#{null}}")
    private String remoteUrl;
