Problem: I need to get all the beans I have created explicitly in my app. When calling applicationContext.getBeanDefinitionNames() I get a list of bean names but a lot of them are not created explicitly by me but by Spring, and I'm not interested in those. There is no naming rule I can use for filtering at this point, because not all the beans injected by Spring start with "org.springframework"
Solution: Using applicationContext.getBeanDefinitionNames() and filtering the beans by my root package name ( This solution also works for other use cases, for example if I want to get all the beans I've defined under a certain package ).
package com.omiu.demo;
....
@Service
class PersonService {}
@Component
class PersonAnalyzer {}
class SimpleAnalyzer {}
@Configuration
class GeneralConfig {
@Bean
public SimpleAnalyzer simpleAnalyzer() {
return new SimpleAnalyzer();
}
}
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
ConfigurableApplicationContext applicationContext = SpringApplication.run(DemoApplication.class, args);
List<Object> myBeans = Arrays.stream(applicationContext.getBeanDefinitionNames())
.filter(beanName -> applicationContext.getBean(beanName).getClass().getPackage().getName().startsWith("com.omiu.demo"))
.map(applicationContext::getBean)
.collect(Collectors.toList());
}
}
This gives me a list of only 5 Beans, exactly those I'm interested in:
