如何将来自规则的值注入到测试spring上下文中

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到的东西，比如:

pluginRule.getEmbeddedToolConfig()

我如何为bean提供该配置，注意该规则是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method initialize中你可以实现你的逻辑
