Java Spring批处理测试在完成后失败，因为上下文未处于活动状态

java spring-boot spring-batch

Java Spring批处理测试在完成后失败，因为上下文未处于活动状态,java,spring-boot,spring-batch,junit5,spring-cloud-task,Java,Spring Boot,Spring Batch,Junit5,Spring Cloud Task,我已经在SpringBatch中创建了一个简单的作业，该作业使用SpringBoot作为SpringCloud任务执行（全部在STS4中）。如果我将其作为Spring Boot应用程序执行，te执行是正确的，没有问题，但是如果我编译项目或尝试启动测试，则作业的执行是正确的： o.s.c.t.b.l.TaskBatchExecutionListener : The job execution id 19 was run within the task execution 56 o.s.batc

我已经在SpringBatch中创建了一个简单的作业，该作业使用SpringBoot作为SpringCloud任务执行（全部在STS4中）。如果我将其作为Spring Boot应用程序执行，te执行是正确的，没有问题，但是如果我编译项目或尝试启动测试，则作业的执行是正确的：

o.s.c.t.b.l.TaskBatchExecutionListener   : The job execution id 19 was run within the task execution 56
o.s.batch.core.job.SimpleStepHandler     : Executing step: [step1]
com.example.demo.MyTasklet               : Executing Tasklet: STEP 1
o.s.batch.core.step.AbstractStep         : Step: [step1] executed in 16ms
o.s.batch.core.job.SimpleStepHandler     : Executing step: [step2]
com.example.demo.MyTasklet               : Executing Tasklet: STEP 2
o.s.batch.core.step.AbstractStep         : Step: [step2] executed in 7ms
o.s.b.c.l.support.SimpleJobLauncher      : Job: [FlowJob: [name=job2]] completed with the following parameters: [{run.id=7, -spring.output.ansi.enabled=always}] and the following status: [COMPLETED] in 52ms
com.zaxxer.hikari.HikariDataSource       : HikariPool-1 - Shutdown initiated...
com.zaxxer.hikari.HikariDataSource       : HikariPool-1 - Shutdown completed.
com.zaxxer.hikari.HikariDataSource       : HikariPool-2 - Shutdown initiated...
com.zaxxer.hikari.HikariDataSource       : HikariPool-2 - Shutdown completed.

但在此之后，出现了一个例外：

o.s.test.context.TestContextManager      : Caught exception while allowing TestExecutionListener [org.springframework.boot.test.autoconfigure.SpringBootDependencyInjectionTestExecutionListener@576d5deb] to prepare test instance [com.example.demo.DemoJobApplicationTests@173ed316]

java.lang.IllegalStateException: The ApplicationContext loaded for [[MergedContextConfiguration@e350b40 testClass = DemoJobApplicationTests, locations = '{}', classes = '{class com.example.demo.DemoJobApplication}', contextInitializerClasses = '[]', activeProfiles = '{}', propertySourceLocations = '{}', propertySourceProperties = '{org.springframework.boot.test.context.SpringBootTestContextBootstrapper=true}', contextCustomizers = set[org.springframework.boot.test.context.filter.ExcludeFilterContextCustomizer@5e82df6a, org.springframework.boot.test.json.DuplicateJsonObjectContextCustomizerFactory$DuplicateJsonObjectContextCustomizer@50a638b5, org.springframework.boot.test.mock.mockito.MockitoContextCustomizer@0, org.springframework.boot.test.web.client.TestRestTemplateContextCustomizer@130161f7, org.springframework.boot.test.autoconfigure.properties.PropertyMappingContextCustomizer@0, org.springframework.boot.test.autoconfigure.web.servlet.WebDriverContextCustomizerFactory$Customizer@479d31f3], 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:94) ~[spring-core-5.2.3.RELEASE.jar:5.2.3.RELEASE]
    at org.springframework.test.context.support.DefaultTestContext.getApplicationContext(DefaultTestContext.java:127) ~[spring-test-5.2.3.RELEASE.jar:5.2.3.RELEASE]
[...]

这使得编译以失败告终，但数据库中的执行被记录为已完成。在名为DefaultTestContext的Spring类中查看生成错误的代码：

@Override
    public ApplicationContext getApplicationContext() {
        ApplicationContext context = this.cacheAwareContextLoaderDelegate.loadContext(this.mergedContextConfiguration);
        if (context instanceof ConfigurableApplicationContext) {
            @SuppressWarnings("resource")
            ConfigurableApplicationContext cac = (ConfigurableApplicationContext) context;
            Assert.state(cac.isActive(), () ->
                    "The ApplicationContext loaded for [" + this.mergedContextConfiguration +
                    "] 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.");
        }
        return context;
    }

。。。问题是“上下文”不是活动的

我尝试了几种注释，如@DirtiesContext、@EnableAutoConfiguration、@SpringBatchTest。。。但似乎没有什么能解决这个问题，所以我希望能有任何想法或帮助。

好吧，经过一番努力，我们找到了解决办法，但这真的是斯图…简单。有必要在pom.xml中更新SpringCloud任务中依赖项的版本，将1.2.2.RELEASE更改为2.2.2.RELEASE
