【中文标题】StrutsSpringJUnit4TestCase freemarker 结果“找不到名称的模板”【英文标题】：StrutsSpringJUnit4TestCase freemarker result "Template not found for name" 【发布时间】：2015-12-16 21:28:03 【问题描述】：

我们一直在尝试将StrutsSpringJunit4TestCase 用于 Struts2，但是当我们运行基本测试时，我们会收到一个我们知道存在的文件的"Template not found for name" 错误：

SEVERE:   [29:39.103] Template not found for name "/WEB-INF/content/errors/error.ftl".
The name was interpreted by this TemplateLoader: org.apache.struts2.views.freemarker.FreemarkerThemeTemplateLoader@7c060680.

调度程序#sendError：500

似乎测试用例没有在src/main/webapp/ 中找到文件，因为适当的文件确实存在于：`src/main/webapp/WEB-INF/content/errors/error.ftl

我们需要做些什么来指导 Struts2 或测试在哪里找到 freemarker 模板？

样本测试：

@ContextConfiguration(classes = TdarWebAppConfiguration.class)
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@Transactional
public class IndexControllerITCase extends StrutsSpringJUnit4TestCase<HomepageSupportingController> 
    protected final Logger logger = LoggerFactory.getLogger(getClass());

    @Test
    public void test() throws Exception 
        ActionProxy proxy = getActionProxy("/robots");
        HomepageSupportingController myAction = (HomepageSupportingController) proxy.getAction();
        logger.debug(executeAction("/robots"));
        String execute = myAction.execute();
        finishExecution();
        logger.debug(response.getContentType());
        logger.debug(response.getContentAsString());
        assertEquals("Error", ActionSupport.SUCCESS, execute);

全栈跟踪：

【问题讨论】：

哪个 S2 版本？ IndexControllerITCase.java:31 是哪一行？显示您尝试执行的操作配置。 Struts2 版本：2.3.24；第 31 行是`HomepageSupportingController myAction = (HomepageSupportingController) proxy.getAction(); ` 我们甚至尝试编写自己的 FreemarkerConfiguration（以提供更好的供应路径，但没有进一步发展）。谢谢 【参考方案1】：

发生这种情况是因为MockServletContext 中使用的弹簧org.springframework.core.io.DefaultResourceLoader 不会像您用于freemarker 结果配置那样加载这样的url-s，例如/WEB-INF/content/errors/error.ftl.

您可以通过覆盖测试中的initServletMockObjects 方法来提供不同的资源加载器。

@Override
protected void initServletMockObjects() 
    servletContext = new MockServletContext(your_custom_resource_loader);
    response = new MockHttpServletResponse();
    request = new MockHttpServletRequest();
    pageContext = new MockPageContext(servletContext, request, response);

【讨论】：

进行以下更改似乎有效：servletContext = new MockServletContext(applicationContext); 你是否碰巧在网上有一个完整工作测试的参考？我们似乎只是在配置问题之后遇到配置问题，并且几乎没有文档。（谢谢） 完全工作的测试...有什么依赖/配置？这个问题是关于使用freemarker 结果测试操作执行。我过去用tiles 的结果做了一些S2 测试，但它们不公开。如果您有更多问题，您可以提出一个新问题，我会看看。祝你好运。
