Maven - Spring请求映射404错误

我已经在SO中看到了很多这样的问题，并且我尝试了他们的解决方案，但他们没有为我工作，所以我会发布这一个。基本上我只是建立一个项目，并试图让我的RequestMapping工作，只是为了返回一个字符串。所以这是我的代码Maven - Spring请求映射404错误

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"; 
    }   
}

好基本上这就是我的代码..不过我浏览到http://localhost:4848/mavenDWP/api/show/hello，我只是得到一个404错误。有任何想法吗？

削减你的榜样一直到尺寸。没有人想穿过100行的pom.xml。 – Teepeemm

如果删除'jasondoc'，问题是否会持续存在？ –

仍然无法解决它。我无法删除jsondoc，因为我需要它来做一些注释 – arrigonfr

添加@ResponseBody注释。每次当你返回一些不是类内部构建的东西，比如ModelAndView，你需要使用这个注解。见docs。

作为建议，即使您有少量数据要发送到客户端，也要尝试使用地图。地图将被转换为JSON并且可以轻松地进行交流。

一切都很好，尝试仅仅指刚在web.xml中删除空格beteween 的servlet类和org.springframework.web.servlet.DispatcherServlet

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

好运
