Spring Integration DSL Unit测试用例在构建脚本中运行时失败

标签： spring-integration spring-integration-dsl

我为Spring集成流程编写了一些单元测试用例。从IDE运行各个测试用例没有问题，但是从gradle构建运行所有测试用例时，一些测试用例都失败了。

我在相关问题上找到了质量控制： https://jira.spring.io/browse/XD-3709

如果有人知道解决方法，请发帖。

带有以下注释的单元测试：

 @RunWith(SpringRunner.class)
    @Import(AlarmAPIApplication.class)
@PropertySource("classpath:application.properties ")
    @FixMethodOrder
    public class HostRegistrationFlowTest {

        @Value("${em.host.registration.url}")
        String hostRegistrationUrl;
        @Autowired
        RestTemplate restTemplate;

        @Autowired
        SubscribableChannel registerHostInputChannel;

        @Test
        public void testRegisterHost() {

从gradle脚本运行时出错：

javax.management.InstanceAlreadyExistsException: org.springframework.integration.router:name=org.springframework.integration.router.MethodInvokingRouter#0,type=MethodInvokingRouter

您必须在测试类级别使用@DirtiesContext以在执行测试后关闭所有应用程序上下文。否则，在测试类初始化期间创建的应用程序上下文不会关闭以在不同测试类之间追踪缓存目标。

在您的情况下，其中一个测试类初始化应用程序上下文并将MBean注册到JMX中。但是不关闭应用程序上下文会导致下一个尝试再次注册MBean。仅仅因为您对不同的测试类使用了一些通用配置。
