Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type in Spring 5

Question

I am trying to write a service using Spring 5, however I receive a Dependency Injection issue. I'm having problems using @Resource.I have recently migrated from Spring 4 to Spring 5.0.5 and have the following jars in the classapath

• spring-aop-5.0.5.RELEASE
• spring-beans-5.0.5.RELEASE
• spring-context-5.0.5.RELEASE
• spring-core-5.0.5.RELEASE
• spring-expression-5.0.5.RELEASE
• spring-test-5.0.5.RELEASE
• junit-4.12

Since you are defining your context configuration for your class as TestClass.OptionalConfiguration then this is the only configuration your tests know about. If you want to define CiScheduledExecutor as a bean in this context as well then you need to component scan for it in your test configuration:

@Configuration
@ComponentScan("my.base.package")
static class OptionalConfiguration {
        @Bean
        List<Item> someString() {
            return new ArrayList<>();
        }
        @Bean
        Object foo(List<Item> obj) {
            return new Object();
        }
    }

Although if you are doing integration like tests that require pulling in several bean definitions from your actual runtime Spring context then you should consider using @SpringBootTest which does a lot of the work for you, see here:
