如何在我的mvc测试执行中包含AbstractContextLoaderInitializer？

标签： java spring-mvc spring-test junit5

背景

我正在通过MockMvcBuilders.webAppContextSetup()将现有应用转换为使用Spring网络集成测试。

我有一个具有以下层次结构的类Initializer： hierarchy

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中，并调用它的重要覆盖方法：

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＆＃34; appType＆＃34;物业来源遗失。 （见底部的堆栈）

问题

如何让这个类包含在mvc集成测试启动中？

答案 0 :(得分：1)

正如参考手册中非常清楚地说明的那样，Spring MVC测试框架在Servlet容器中执行而不是。

因此，您无法将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：

  1. 使用@TestPropertySource
  2. 实施自定义ApplicationContextInitializer并通过initializers中的@ContextConfiguration进行注册。
