如何将 AbstractContextLoaderInitializer 包含到我的 mvc 测试执行中？
How do I include an AbstractContextLoaderInitializer into my mvc test execution?
背景
我正在通过 MockMvcBuilders.webAppContextSetup().
将现有应用程序转换为使用 spring 网络集成测试
我有一个 class Initializer 具有以下层次结构：
当应用程序运行时，class 会被 SpringServletContainerInitializer 自动检测并包含在上下文实例化中，并且重要的重写方法被调用：
protected WebApplicationContext createRootApplicationContext() {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ConfigurableEnvironment env = ctx.getEnvironment();
// other stuff
env.getPropertySources().addLast(new MapPropertySource("appType", aHashMapImadeWithImportantStuff));
}
问题
但是在 mock mvc 测试执行期间，上述 "appType" 属性 源代码丢失了。 （见底部的堆栈）
问题
我该怎么做才能将此 class 包含在 mvc 集成测试启动中？

如参考手册中所述，Spring MVC 测试框架不在 Servlet 容器内执行。
因此，您根本无法将 Tomcat 的 context.xml 文件、web.xml 或 WebApplicationInitializer 与 MVC 测试结合使用。
要设置 appType 属性，您有两个选择：
- 使用
@TestPropertySource
- 实施自定义
ApplicationContextInitializer 并通过 @ContextConfiguration 中的 initializers 进行注册。
