Maven - Spring請求映射404錯誤

我已經在SO中看到了很多這樣的問題，並且我嘗試了他們的解決方案，但他們沒有爲我工作，所以我會發布這一個。基本上我只是建立一個項目，並試圖讓我的RequestMapping工作，只是爲了返回一個字符串。所以這是我的代碼Maven - Spring請求映射404錯誤

調度-servlet.xml中

     <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> 
      <property name="objectMapper"> 
       <bean class="ve.com.HibernateAwareObjectMapper" /> 
      </property> 
     </bean> 
    </mvc:message-converters> 
</mvc:annotation-driven> 

<bean id="documentationController" class="org.jsondoc.springmvc.controller.JSONDocController"> 
    <constructor-arg name="version" value="1.0"/> 
    <constructor-arg name="basePath" value="http://localhost:4848/mavenDWP/api"/> 
    <constructor-arg name="packages"> 
    <list> 
    <value>ve.com</value> 
    </list> 
    </constructor-arg> 
</bean>

LinkController

package ve.com.controller; 

import org.jsondoc.core.annotation.ApiMethod; 
import org.jsondoc.core.annotation.ApiResponseObject; 
import org.jsondoc.core.annotation.ApiVersion; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 
import org.springframework.web.bind.annotation.RestController; 

@Controller 
@ApiVersion(since="1.0") 
@RequestMapping("/show") 
public class LinkController { 

    @Autowired 
    private StockService stockService; 

    @RequestMapping(method = RequestMethod.GET, value="/hello") 
    public String showHello() { 
     return "hello"; 
    }   
}

好基本上這就是我的代碼..不過我瀏覽到http://localhost:4848/mavenDWP/api/show/hello，我只是得到一個404錯誤。有任何想法嗎？

削減你的榜樣一直到尺寸。沒有人想穿過100行的pom.xml。 – Teepeemm

如果刪除'jasondoc'，問題是否會持續存在？ –

仍然無法解決它。我無法刪除jsondoc，因爲我需要它來做一些註釋 – arrigonfr

添加@ResponseBody註釋。每次當你返回一些不是類內部構建的東西，比如ModelAndView，你需要使用這個註解。見docs。

作爲建議，即使您有少量數據要發送到客戶端，也要嘗試使用地圖。地圖將被轉換爲JSON並且可以輕鬆地進行交流。

一切都很好，嘗試僅僅指剛在web.xml中刪除空格beteween 的servlet類和org.springframework.web.servlet.DispatcherServlet

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

好運
