Spring - 未找到具有URI的HTTP請求的映射

Question

我正在編寫Spring服務器，並使用Retrofit進行api調用。

我對改造客戶端的下一個界面：

import retrofit.http.Body; 
import retrofit.http.GET; 
import retrofit.http.POST; 

public interface AuthSvcApi { 

    public static final String AUTHENTICATION_PATH = "/authToken"; 

    @POST(AUTHENTICATION_PATH) 
    public boolean loginUser(@Body String accessToken); 
} 

然後我的控制器：

import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestBody; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 
import org.springframework.web.bind.annotation.ResponseBody; 

import com.purposes.client.AuthSvcApi; 

@Controller 
public class AuthSvc{ 

    @RequestMapping(value=AuthSvcApi.AUTHENTICATION_PATH, method = RequestMethod.POST) 
    public @ResponseBody boolean loginUser(@RequestBody String accessToken) { 
     CheckAccessToken checkAccessToken = new CheckFacebookAccessToken(); 
     checkAccessToken.checkToken(accessToken); 
     return false; 
    } 
} 

的方法還沒有完成，但它應該工作。而應用程序類是：

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 
import org.springframework.context.annotation.ComponentScan; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.web.servlet.config.annotation.EnableWebMvc; 


//Tell Spring to automatically inject any dependencies that are marked in 
//our classes with @Autowired 
@EnableAutoConfiguration 
//Tell Spring to turn on WebMVC (e.g., it should enable the DispatcherServlet 
//so that requests can be routed to our Controllers) 
@EnableWebMvc 
//Tell Spring to go and scan our controller package (and all sub packages) to 
//find any Controllers or other components that are part of our applciation. 
//Any class in this package that is annotated with @Controller is going to be 
//automatically discovered and connected to the DispatcherServlet. 
@ComponentScan 
//Tell Spring that this object represents a Configuration for the 
//application 
@Configuration 
public class Application { 

    public static void main(String[] args) { 
     SpringApplication.run(Application.class, args); 
    } 
} 

我不知道爲什麼，這並不正常工作，但我要瘋了，因爲反應是：

No mapping found for HTTP request with URI [/authToken] in DispatcherServlet with name 'dispatcherServlet' 

Answer 1

那麼，我找到了解決方案，問題是註釋@ComponentScan沒有找到控制器所在的包。我解決了向註解指示控制器所在的包的問題。

@ComponentScan(basePackages={"com.purposes.controllers"})

Answer 2

看起來你需要包括AuthSvcApi.AUTHENTICATION_PATH 這一行：

.setEndpoint(SERVER).build()

像這樣： .setEndpoint(SERVER + AuthSvcApi.AUTHENTICATION_PATH).build()
