I am getting 400 Bad Request when I send a request to Rest Service from JUnit Test case. PFB my code. The error log is towards the end. Kindly help me in resolving the issue. I am not getting any error when I call the server as: restTemplate.getForObject(BASE_URL + "/remote?serviceName=simpleService&source=WEB", HelloWorld.class) by passing the parameters directly in the URL. But how to pass using the map, that is where issue is coming.
My Controller:
@Controller
@RequestMapping("/remote")
public class RESTController implements IController{
@RequestMapping(method = RequestMethod.GET, headers = "Accept=application/xml, application/json")
public @ResponseBody HelloWorld getMessage(@RequestParam("serviceName") String serviceName, @RequestParam("source") String source) throws ApplicationException{
System.out.println("got the request:");
serviceLocator serviceLocator = new serviceLocator();
HelloWorld helloWorld = new HelloWorld();
helloWorld.setMessage(serviceLocator.getMessage(serviceName));
return helloWorld;
}
