Spring REST實現錯誤404

我正在嘗試使用here的教程來開發測試REST應用程序。我把它作爲一場戰爭來部署，通過在我的戰爭中包括戰爭，並且構建了沒有錯誤的應用程序。當涉及到打開網址，localhost:8080/gs-rest-service/rest/greeting我得到一個404錯誤 - 更具體地是No mapping found for HTTP request with URI [/gs-rest-service/rest/greeting] in DispatcherServlet with name 'mvc-dispatcher'。我似乎無法看到什麼是錯的，我檢查了我的上下文根設置爲gs-rest-service，我GreetingController類看起來是這樣的：Spring REST實現錯誤404

package hello; 

import java.util.concurrent.atomic.AtomicLong; 
import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestParam; 
import org.springframework.web.bind.annotation.ResponseBody; 

@Controller 
public class GreetingController { 

private static final String template = "Hello, %s!"; 
private final AtomicLong counter = new AtomicLong(); 

@RequestMapping("/greeting") 
public @ResponseBody Greeting greeting(
     @RequestParam(value="name", required=false, defaultValue="World") String name) { 
    return new Greeting(counter.incrementAndGet(), 
         String.format(template, name)); 
}

}

這裏是我的web.xml：

    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
</listener>

這裏是我的MVC-調度-servlet.xml中

<beans xmlns="http://www.springframework.org/schema/beans" 
xmlns:context="http://www.springframework.org/schema/context" 
xmlns:mvc="http://www.springframework.org/schema/mvc"

</beans>

This is my project layout:

會有人能夠幫助我在這裏找到問題？

請張貼您的啓動日誌。 –

@SotiriosDelimanolis日誌位於哪裏？ – AkshaiShah

你沒有指定contextConfig位置

<init-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value></param-value> 
    </init-param>

PARAM價值的缺失。請給出mvc-dispatcher-servlet.xml的位置，然後再試一次。希望這可以幫助

位置是mvc-servlet-dispatcher？ – AkshaiShah

這將是你的mvc-dispatcher-servlet.xml – Keerthivasan

剛剛看到這個，試試吧 – AkshaiShah
