I using spring Spring boot 2.1.0.
public Mono<ServerResponse> getConvertXmlToJson(ServerRequest serverRequest) {
Mono<String> requestString = serverRequest.bodyToMono(String.class);
Mono<String> response = this.convertFormatService.convertXmlToJson(requestString);
return response.subscribeOn(elastic()).flatMap(rta -> ok()
.contentType(APPLICATION_JSON_UTF8)
.body(fromObject(rta)))
.switchIfEmpty(ServerResponse.badRequest().build());
}
call this method in other bean
private Mono<String> converter(String function, Mono<String> stringToConverter, String setting) {
log.info("salida, {}", stringToConverter.block());
try {
Object result = invocable.invokeFunction(function, stringToConverter, setting);
log.info("{}", result);
return Mono.just((String) result);
} catch (Exception e) {
throw new ConverterException(e.getMessage());
}
}
I need to pass a string value no a Mono, when I pass Mono the answer is empty.
When I try to get a string value from Mono I get this error:
