Tiles問題：運行JUnit測試時無法加載ApplicationContext

我正在嘗試使用JUnit測試Spring MVC控制器。Tiles問題：運行JUnit測試時無法加載ApplicationContext

這是我如何配置JUnit類中我的上下文：

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

然後我自動裝配我的控制器像往常一樣在測試：

@Autowired 
private PliController pliController;

，我得到以下錯誤，當我運行測試：

任何人都可以幫忙嗎？

編輯1：請注意，此問題不會發生在測試環境之外。

編輯2：感謝六必居，我設法得到它的工作：這裏是相關配置：

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();

的原因是瓷磚配置需要一個ServletContext的可用性，這是不存在的與JUNIT一起運行時。我過去使用的修復方法是使用新的Spring-test-mvc（也可在Spring 3.2RC1中使用）模塊來測試Spring控制器，並且很好地支持在Web上下文中加載。

我想通了這一點（與servlet上下文的可用性問題），並即將在此發佈回覆。 – balteo

但是，我不確定如何使用spring-mvc-test來加載web上下文......請問我可以指向相關代碼部分嗎？ – balteo

有同樣的問題，固定註釋測試類@WebAppConfiguration

而且在classpath添加下面的依賴關係：

<dependency> 
    <groupId>junit</groupId> 
    <artifactId>junit</artifactId> 
    <version>4.12</version> 
    <scope>test</scope> 
</dependency> 
<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-test</artifactId> 
    <version>4.1.4.RELEASE</version> 
    <scope>test</scope> 
</dependency> 
<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>javax.servlet-api</artifactId> 
    <version>3.0.1</version> 
</dependency> 
<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>jsp-api</artifactId> 
    <version>2.0</version> 
</dependency>
