spring-mvc - org.springframework.web.servlet.DispatcherServlet noHandlerFound MockMvc を介してテストする場合

Question

Spring Mvc 4 を使用してレスト サービスを定義し、MockMvc を使用して同じサービスをテストしました。次の URL から Tomcat 7 を使用してサービスを実行すると、正しい応答が返されます。

http://localhost:8080/SpringServiceSample/service/greeting/Niharika

しかし、Junit テストを実行すると、ログに次のような 404 エラーが表示されます。

INFO: FrameworkServlet '': initialization completed in 159 ms
May 18, 2015 12:36:02 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/service/greeting] in DispatcherServlet with name ''

コードは次のとおりです。

SpringServiceController.java

package com.test.springservice.controller;

import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/service/greeting")
public class SpringServiceController {
    @RequestMapping(value = "/{firstName}", method = RequestMethod.GET)
    @ResponseBody
    public String getGreeting(
        @PathVariable String firstName) {
        String result = "Hello " + firstName;
        return result;
    }
}
