RESS, Java Spring이있는 Hessian Webservice

Question

Hessian 서비스와 함께 REST 서비스를 사용할 수 있습니까?

내가이 인터페이스를 가지고 정교하게하려면 :

@Controller 
public interface PhotoServices { 

    @RequestMapping(value = "/{user}/{folder_name}/savephoto/", method = RequestMethod.POST) 
    public @ResponseBody Object savePhoto(HttpServletRequest request, @PathVariable("user")String user, @PathVariable("folder_name")String folder_name, @ModelAttribute("photo") Photo photo, BindingResult result, SessionStatus session); 

    @RequestMapping(value = "/user/getuserphotos/", method = RequestMethod.GET) 
    public @ResponseBody Object getUserPhotos(HttpServletRequest request); 

    @RequestMapping(value = "/{user}/{folder_name}/photo/{filename}", method = RequestMethod.GET, produces="image/jpg") 
    public @ResponseBody byte[] getPhoto(@PathVariable("user")String user, @PathVariable("folder_name")String folder_name, @PathVariable("filename") String filename); 

} 

나는 그것이 순전히 RESTful 서비스하지만, 요구 사항의 변화뿐만 아니라 헤센 서비스를 구현하기 위해 저를 필요가 있다는 생각이 인터페이스를 만들었습니다. 그대로

헤 시안에 대해이 인터페이스를 사용하면 다음과 같이 봄이 오류를 던지고있다 : 명확하게 하더군요

를 하나 내가 잘못 REST와 헤 시안을 통합하고있어 이들 두 사람은 같은에 존재할 수 없습니다 동시에 서비스를 제공 할 수 있습니다 ...

그래서 Hessian은 REST와 함께 작업 할 수 없습니까? 아니면 마술을 만들기위한 구성 라인이 누락 되었습니까?

Answer 1

내가하는 것이 좋습니다 것이다

는 (. 박사 포스트 사람들이 당신이 필요로하고 내가 TL을하지 않으려는 정말로 확실하지 it..I'm를 요청할 경우 추가 미리보기가 제공됩니다) @Service로 표시된 클래스의 serivce에 비즈니스 로직을 넣습니다. 그러면 프론트 엔드는 http 또는 기타 hessian 또는 RMI 또는 SOAP 용 어댑터 또는 무엇이 던져지고 있는지에 대한 컨트롤러입니다.

// pure business logic method here no dependency on servlets or any network protocol just pojos in 
// pojos out 
@Service 
public interface PhotoServices { 
    public void doSomething(....) 

} 

/** 
* Restful interface knows about Sevlets request and response http status codes ... etc\ 
* does web stuff and delegates to the PhotoService 
*/ 
@Controller 
public class PhotoWebController { 

@Autowired 
private PhotoService photoSerivce; 

    @RequestMapping .... 
    public void doSemething(....) 
    { 
     this.photoSerivce.doSomething(....) 
    } 
} 




/** 
* RPC end point understand how to handle error conditions with Hessian ... etc 
* 
*/ 
// put whatever annoations you need to put for hessian 
public class PhotoHessianController { 

@Autowired 
private PhotoService photoSerivce; 

    // hessian annotations go here 
    public void doSemething(....) 
    { 
     this.photoSerivce.doSomething(....) 
    } 
} 

나는 헤센을 사용하지 않았으므로 헤센과 함께하는 방법에 대한 세부 정보를 제공 할 수 없습니다.
