JUnit を使用して Spring MVC コントローラーをテストしようとしています。

JUnit クラス内でコンテキストを構成する方法は次のとおりです。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:/META-INF/spring/applicationContext*.xml", "file:src/main/webapp/WEB-INF/spring/webmvc-config.xml" })

次に、テストで通常どおりコントローラーを自動配線します。

@Autowired
private PliController pliController;

テストを実行すると、次のエラーが表示されます。

誰でも助けることができますか？

編集 1 : この問題はテスト環境以外では発生しないことに注意してください。

EDIT 2：Bijuのおかげで、私はそれを機能させることができました：関連する設定は次のとおりです：

private String contextLocWeb = "file:src/main/webapp/WEB-INF/spring/webmvc-config.xml";
private String contextLoc = "classpath:/META-INF/spring/applicationContext*.xml";
private String warDir = "src/main/webapp";

MockMvc mockMvc = MockMvcBuilders.xmlConfigSetup(contextLocWeb, contextLoc).configureWebAppRootDir(warDir, false).build();

その理由は、タイル構成にはServletContextの可用性が必要であり、これはJUNITで実行している場合には存在しないためです。私が過去に使用した修正は、Springコントローラーのテストに新しいSpring-test-mvc（Spring 3.2RC1でも利用可能）モジュールを使用することであり、Webコンテキストでの読み込みを適切にサポートしています。
