测试中的自发启动Spring Boot上下文

Question

我在spring TestContext配置的深潜过程中遇到了spring-boot-test问题。

示例项目：github示例项目

我有三个带有bean的Spring配置(config1-重量级配置，我需要缓存它）

@ContextHierarchy({
    @ContextConfiguration(classes = {Config1.class}),
    @ContextConfiguration(classes = {Config2.class}),
})

Started ConfigTest1

两次然后

Started ConfigTest2

只有一次。在我看来，这是可能的，因为configtest1已经缓存为TestContext（发生这种情况是因为configtest1和configtest2包含在同一个包中）

这意味着spring启动我的spring上下文三次！为什么？在日志中查看三次spring boot logo：

  .   ____          _            __ _ _
 /\\ / ___'_ __ _ _(_)_ __  __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \
 \\/  ___)| |_)| | | | | || (_| |  ) ) ) )
  '  |____| .__|_| |_|_| |_\__, | / / / /
 =========|_|==============|___/=/_/_/_/
 :: Spring Boot ::        (v1.5.2.RELEASE)

更新1：

多谢.但是，如果我在@SpringBootTest中在两个测试类中以不同的顺序设置属性（或类），则不会缓存任何配置：（

@RunWith(SpringRunner.class)
@SpringBootTest
@ContextHierarchy({
    @ContextConfiguration(classes = {Config1.class}),
    @ContextConfiguration(classes = {Config2.class}),
})
public class ConfigTest1 {

和

@RunWith(SpringRunner.class)
@SpringBootTest(properties = "property1=1")
@ContextHierarchy({
    @ContextConfiguration(classes = {Config1.class}),
    @ContextConfiguration(classes = {Config3.class}),
})
public class ConfigTest2 {

一切都在正常运转！

您之所以感到困惑，是因为Spring Boot记录了为其加载ApplicationContext的测试类的名称。因此，您会在日志中两次看到configtest1，因为为该测试类加载了两个上下文。

如果将logging.level.org.springframework.test.context.cache=debug添加到application.properties中，您将看到以下日志输出。
