private String A;

@Value ("${test.b}")
private String B;

@Value ("${test.c}")
private String C;

@Value ("${test.d}")
private String D;

private static String other;
static {
ResourceBundle Obundle = Resourcebundle.getbundle ("other");
other = Obundle.getstring ("Other.config");
}

@GetMapping ("/test") public
String Testconfig () {
return a + ";" + B + ";" + C + ";" + D + ";" + oth er;
}
