java - 禁用@EnableAutoConfiguration

Question

我想知道如何摆脱@EnableAutoConfiguration。

spring boot documentation提到了

If you need to find out what auto-configuration is currently being applied, and why, starting your application with the --debug switch

但我找不到 shell 中应用了哪些自动配置。

它看起来怎么样？如何为我的应用程序导入/启用必要的配置？我特别感兴趣的是加载 spring 数据自动配置以快速运行集成测试。

添加

@RunWith(SpringJUnit4ClassRunner.class)
@EntityScan("persistence.entities")
@EnableJpaRepositories("persistence.repositories")
@ActiveProfiles("dev")
@Configuration
@Import({ AopAutoConfiguration.class, AopAutoConfiguration.JdkDynamicAutoProxyConfiguration.class,
        AuditAutoConfiguration.class, DataSourceAutoConfiguration.class,
        DataSourceAutoConfiguration.class, DataSourceAutoConfiguration.class,
        DataSourcePoolMetadataProvidersConfiguration.class,
        DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class,
        JpaBaseConfiguration.class, JpaRepositoriesAutoConfiguration.class,
        JtaAutoConfiguration.class, ManagementServerPropertiesAutoConfiguration.class,
        PersistenceExceptionTranslationAutoConfiguration.class,
        PropertyPlaceholderAutoConfiguration.class, ServerPropertiesAutoConfiguration.class,
        ServerPropertiesAutoConfiguration.class, SpringDataWebAutoConfiguration.class })
@EnableIntegration
@SpringApplicationConfiguration(classes = QueryTests.class)
public class QueryTests {...

我的 JUnit 测试现在抛出一个 java.lang.IllegalStateException:无法检索 @EnableAutoConfiguration 基础包(见下文)。

Caused by: java.lang.IllegalStateException: Unable to retrieve @EnableAutoConfiguration base packages
    at org.springframework.boot.autoconfigure.AutoConfigurationPackages.get(AutoConfigurationPackages.java:77) ~[spring-boot-autoconfigure-1.2.5.RELEASE.jar:1.2.5.RELEASE]

Answer 1

要在日志中查看 Spring Boot 内容，当我从 IDEA 运行 Boot 应用程序时，我将 --debug 添加到 Program Arguments 中。从命令行来看，它看起来像:

D:\Java\jdk8\bin\java -Didea.launcher.port=7533 "-Didea.launcher.bin.path=D:\IntelliJ IDEA\bin" -Dfile.encoding=windows-1252 -classpath "[SOME CP]" com.intellij.rt.execution.application.AppMain org.springframework.integration.samples.dsl.cafe.lambda.Application --debug

这样我就可以在控制台中看到类似这样的内容:

=========================
AUTO-CONFIGURATION REPORT
=========================


Positive matches:
-----------------

   AopAutoConfiguration
      - @ConditionalOnClass classes found: org.springframework.context.annotation.EnableAspectJAutoProxy,org.aspectj.lang.annotation.Aspect,org.aspectj.lang.reflect.Advice (OnClassCondition)
      - matched (OnPropertyCondition)

   AopAutoConfiguration.JdkDynamicAutoProxyConfiguration
      - matched (OnPropertyCondition)

   GenericCacheConfiguration
      - Automatic cache type (CacheCondition)

等等。

对于你的第二个问题，有两种方法:

• 使用@SpringBootApplication(exclude)禁用不需要的自动配置

• 不依赖Boot，只需导入所需的配置。例如:

  @Configuration
  @Import({PropertyPlaceholderAutoConfiguration.class, ServerPropertiesAutoConfiguration.class,
      EmbeddedServletContainerAutoConfiguration.class, DispatcherServletAutoConfiguration.class})
  @EnableIntegration
  public static class ContextConfiguration {
