Java.lang.IllegalStateException

1.啟動項目沒問題

2.使用Springboot的test類Debug的時候報錯

java.lang.IllegalStateException: The ApplicationContext loaded for [[MergedContextConfiguration@1a75e76a testClass = CheckSystemChangeApplicationTests, locations = '{}', classes = '{class com.deltaww.CheckSystemChangeApplication}', contextInitializerClasses = '[]', activeProfiles = '{}', propertySourceLocations = '{}', propertySourceProperties = '{org.springframework.boot.test.context.SpringBootTestContextBootstrapper=true}', contextCustomizers = set[org.springframework.boot.test.context.filter.ExcludeFilterContextCustomizer@7c729a55, org.springframework.boot.test.json.DuplicateJsonObjectContextCustomizerFactory$DuplicateJsonObjectContextCustomizer@5af3afd9, org.springframework.boot.test.mock.mockito.MockitoContextCustomizer@0, org.springframework.boot.test.web.client.TestRestTemplateContextCustomizer@6572421, org.springframework.boot.test.autoconfigure.actuate.metrics.MetricsExportContextCustomizerFactory$DisableMetricExportContextCustomizer@dd8ba08, org.springframework.boot.test.autoconfigure.properties.PropertyMappingContextCustomizer@0, org.springframework.boot.test.autoconfigure.web.servlet.WebDriverContextCustomizerFactory$Customizer@131774fe, org.springframework.boot.test.context.SpringBootTestArgs@1, org.springframework.boot.test.context.SpringBootTestWebEnvironment@768debd], contextLoader = 'org.springframework.boot.test.context.SpringBootContextLoader', parent = [null]]] is not active. This may be due to one of the following reasons: 1) the context was closed programmatically by user code; 2) the context was closed during parallel test execution either according to @DirtiesContext semantics or due to automatic eviction from the ContextCache due to a maximum cache size policy.at org.springframework.util.Assert.state(Assert.java:97)at

最后發現是程序中使用了ConfigurableApplicationContext

@Component public class MyRunner implements ApplicationRunner {@Autowiredprivate CheckDataController checkDataController;@Autowiredprivate ConfigurableApplicationContext context;@Overridepublic void run(ApplicationArguments args) throws Exception {checkDataController.checkDataChange();System.out.println("automatically turn off tomcat");context.close();} }

所以，debug的時候把這行注釋掉

// context.close(); 注掉

是不是無語的很，Tomcat都已經關閉了，誰還給你Debug呀
