Spring MVC - App适用于本地tomcat，但在部署到heroku时返回404

标签： java spring heroku

我有一个Spring MVC应用程序，当我在本地tomcat服务器上运行时，它可以正常工作。但是当我将它部署到heroku时，我收到了以下404错误：

The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

我正在使用eclipse，我还使用eclipse将我的应用程序部署到heroku

这是我的pom.xml：

这是我的servlet映射文件：

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

</servlet>
<servlet-mapping>
    <servlet-name>themis</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

这是我的控制器类：

package themis;

@RestController
public class Themis {

@RequestMapping(value = "/test", method = RequestMethod.POST)
public @ResponseBody APIResponse test(@RequestBody APIRequest req) {
    System.out.println("Received request: " + req);
    APIResponse response = new APIResponse();
    response.setUser_id(req.getUser_id());
    response.setModule_id(req.getModule_id());
    response.setBot_id(req.getBot_id());
    response.setMessage(req.getIncoming_message());
    System.out.println("Sending response: " + response);
    return response;
}

@RequestMapping(value = "/test", method = RequestMethod.GET)
public @ResponseBody APIResponse testGet() {
    APIResponse response = new APIResponse();
    response.setUser_id(1);
    response.setModule_id(2);
    response.setBot_id(3);
    response.setMessage("Get works");
    System.out.println("Sending response: " + response);
    return response;
}

}

我尝试查询的网址是：

https://hidden-reef-68162.herokuapp.com/themis/test

当我使用url localhost：8080 / themis / test在本地tomcat上运行应用程序时，它完全有效。但上面的网址失败了......

部署到heroku时没有错误。

对于什么是错误的任何想法？

以下是我在heroku中获得的日志：
