所以这是一个非常基本的 spring-boot 项目，只有 6 个类。

设置非常基本，只有一个测试用例失败。我得到的例外是
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.context.NoSuchMessageException: No message found under code 'custom.link' for locale 'en'.

我相信这是因为SpringApplicationContextLoaderline 255, 方法通过调用只接受路径的构造函数来addMockServletContext创建 a 。MockServletContext结果，内部使用MockServletContext初始化ResourceLoader，DefaultResourceLoader它将在类路径中查找资源。这样，如果我有一个ReloadableResourceMessageResolver并且我的属性文件在/WEB-INF/messages/base.properties其中，它将永远找不到它们，因为它/WEB-INF/messages/base.properties被转换为src/main/webapp/WEB-INF/messages/base.properties在类路径中找不到的ReloadableMessageSourceResolver. 我认为在创建时MockServletContext应该能够显式传递FileSystemResourceLoader，对吗？
