Java 如何在mvc测试执行中包含AbstractContextLoaderInitializer？ 背景

我正在通过

MockMvcBuilders.webAppContextSetup（）

将现有应用程序转换为使用SpringWeb集成测试

我有一个具有以下层次结构的类

初始值设定项
：

当应用程序运行时，
SpringServletContainerInitializer
会自动检测该类并将其包含在上下文实例化中，它的重要重写方法被调用：

protected WebApplicationContext createRootApplicationContext() {
    AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
    ConfigurableEnvironment env = ctx.getEnvironment();
    // other stuff
    env.getPropertySources().addLast(new MapPropertySource("appType", aHashMapImadeWithImportantStuff));
}

问题
但是在模拟mvc测试执行期间，前面提到的“appType”属性源丢失。（见底部的堆栈）

问题
我该怎么做才能让这个类包含在mvc集成测试启动中


堆栈
正如参考手册中明确指出的，SpringMVC测试框架不在Servlet容器中执行

因此，您不能将Tomcat的
context.xml
文件、
web.xml
或
WebApplicationInitializer
与MVC测试结合使用

要设置
appType
属性，您有两个选项：

使用
@TestPropertySource
实现自定义的
ApplicationContextInitializer
，并通过
@ContextConfiguration
中的
初始值设定项注册它

一个可能相关的问题是如何将现有的tomcat context.xml文件包含到集成测试上下文中。它包括appType属性和其他内容，比如datasource.BTW，很高兴看到您正在使用JUnit5和
SpringExtension
；）非常兴奋。我遇到的问题是如何让SpringMVC集成测试在Servlet容器之外运行。有一些bean（我的、依赖项和可传递依赖项），我在测试期间很难让它们满意。
