在测试中自发启动 spring 启动上下文
Spontaneous up spring boot context in test
我在深入研究 spring TestContext 配置时遇到 spring-boot-test 问题。
我有三个 Spring 配置和一些 bean（Config1 - 重量级配置，我需要缓存它）
我在上下文中使用 @ContextHierarchy 作为单独的配置，我希望 Config1 只会加载一次。 （使用@ContextHierarchy 因为我没有在 spring-boot-test 中找到类似物）
完整代码：
@ContextHierarchy({
@ContextConfiguration(classes = {Config1.class}),
@ContextConfiguration(classes = {Config2.class}),
})
如果我运行测试，Config1真的被缓存了！但是，我看到以下内容：
Started ConfigTest1
两次
并且
Started ConfigTest2
只有一次。在我看来，这是可能的，因为 ConfigTest1 已经缓存为 TestContext（它发生了，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？
在日志中看到spring三次开机标志：

非常感谢。但是，如果我在两个测试 类 中以不同的顺序在 @SpringBootTest 中设置属性（或 类）——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 {
如果没有属性 – config1 真的会被缓存！在这种情况下——没有缓存
一切正常！
您只是感到困惑，因为 Spring Boot 记录了加载 ApplicationContext 的测试 class 的名称。因此，您会在日志中看到两次 ConfigTest1，因为为该测试加载了两个上下文 class.
如果将 logging.level.org.springframework.test.context.cache=debug 添加到 application.properties，您将看到以下日志输出。
