Junit 5测试，得到java.lang.IllegalStateException：测试类不能包含@Bean方法

Question

@ContextConfiguration(classes = ConfigureCustomConfigurationModelProviderTest.class)
    public class ConfigureCustomConfigurationModelProviderTest extends AbstractContextTest {
        @Bean(name = "smth")
        public static ConfigurationModelProvider get() {
            return AnnotationConfigurationModelProvider.getInstance();
        }
        /*...*/
    }

我从junit4迁移到junit5后出现此错误。为什么呢？

Answer 1

您应该将每个bean移至@Configuration类，例如TestConfig：

@Configuration
public class TestConfig {

    @Bean(name = "smth")
    public static ConfigurationModelProvider get() {
        return AnnotationConfigurationModelProvider.getInstance();
    }
}

并通过@Import

导入

@Import({TestConfig.class})
@ContextConfiguration(classes = ConfigureCustomConfigurationModelProviderTest.class)
public class ConfigureCustomConfigurationModelProviderTest extends AbstractContextTest {
}
