Spring: No default constructor found - spring

Question

My english isn't perfect or even good but I will try to explain my problem.
I need to write in my application REST client which is using Wiki API to get some necessary data.I have no idea what is wrong with this code.
Here is my client:
#Component("wikiService")
public class WikiServiceImpl implements WikiService {
private Log log = LogFactory.getLog(WikiServiceImpl.class);
private String wikiBaseURL = "http://pl.wikipedia.org/w/api.php?action=query&prop=revisions&titles={name}&rvprop=content&";
private final RestTemplate restTemplate;
public WikiServiceImpl() {
restTemplate = new RestTemplate();
}
#Autowired
public WikiServiceImpl(RestTemplate restTemplate) {
this.restTemplate = restTemplate;
}
// other metods ommited
Controller:
#Controller
#RequestMapping(value="/ask")
public class WikiController {
final Logger logger= LoggerFactory.getLogger(WikiController.class);
#Autowired
private WikiService wikiService;
#RequestMapping(value="/{query}", method=RequestMethod.GET)
#ResponseBody
public String getAnswer(#PathVariable String query) {
logger.info("Odebralem zapytanie: " + query);
String bDate = wikiService.getBirthDate(query);
logger.info("Znaleziona data: " + bDate);
return bDate;
}
public final WikiService getWikiService() {
return wikiService;
}
public final void setWikiService(WikiService wikiService) {
this.wikiService = wikiService;
}
}
Here is rest servlet context:

Stack says container can't find default constructor which actually is there.
Application is running on TomCat 7.0 Server.
Thanks for help.

As the error is impossible with the source code you shared with us, my guess would be that your server contains old class (i.e. the source code we see is not being used).
I suggest to clean the project and also Tomcat installation in your IDE.
On project in Eclipse (if that is your IDE):
Menu Project => Clean ...
On Tomcat in Eclipse (if that is your IDE):
Right click on the server in Servers view => Clean ...
