spring - 如何将来自规则的值注入(inject)测试 Spring 上下文？

Question

假设您在测试 spring 上下文时遇到以下情况

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {ConfigClass.class})
public class IntegrationTest   {

 @ClassRule 
 static PluginThatSetsUpSomethingEmbedded pluginRule = new PluginThatSetsUpSomethingEmbedded();



}

现在我的一个 Spring bean 需要一些只能从规则中得出的东西，比如:

pluginRule.getEmbeddedToolConfig()

我如何为我的 bean 提供该配置，请注意规则是 ClassRule 并且也是静态的...

我建议你使用ApplicationContextInitializer你的测试类将是这样的:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {ConfigClass.class}, initializers = IntegrationTest.Initializer.class)
public class IntegrationTest   {

 @ClassRule 
 static PluginThatSetsUpSomethingEmbedded pluginRule = new PluginThatSetsUpSomethingEmbedded();

 public static class Initializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
    @Override
    public void initialize(ConfigurableApplicationContext configurableApplicationContext) {
    }


}

在初始化方法中，您可以实现您的逻辑。
