java - 如何将 AbstractContextLoaderInitializer 包含到我的 mvc 测试执行中？

Question

背景

我正在通过 MockMvcBuilders.webAppContextSetup() 将现有应用程序转换为使用 Spring Web 集成测试.

我有课Initializer具有以下层次结构:

当应用程序运行时，该类会被 SpringServletContainerInitializer 自动检测到并包含在上下文实例化中。 ，并且调用了重要的重写方法:

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“appType”属性源丢失了。 (参见底部的堆栈)

问题

我该怎么做才能将此类包含在 mvc 集成测试启动中？

Answer 1

正如引用手册中明确指出的那样，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，您有两种选择:

1. 使用@TestPropertySource
2. 实现自定义 ApplicationContextInitializer 并通过 @ContextConfiguration 中的初始化器 注册它。
