[java] 로드 된 모든 Spring Bean을 인쇄하십시오.

applicationContext.getBeanDefinitionNames () 는 BeanDefinition 인스턴스 없이 등록 된 Bean을 표시 하지 않습니다 .

스프링 부트 웹 애플리케이션의 경우 아래 엔드 포인트를 사용하여 모든 Bean을 나열 할 수 있습니다.

@RestController
@RequestMapping("/list")
class ExportController {

@Autowired
private ApplicationContext applicationContext;

@GetMapping("/beans")
@ResponseStatus(value = HttpStatus.OK)
String[] registeredBeans() {
    return printBeans();
}

private String[] printBeans() {
    AutowireCapableBeanFactory autowireCapableBeanFactory = applicationContext.getAutowireCapableBeanFactory();
    if (autowireCapableBeanFactory instanceof SingletonBeanRegistry) {
        String[] singletonNames = ((SingletonBeanRegistry) autowireCapableBeanFactory).getSingletonNames();
        for (String singleton : singletonNames) {
            System.out.println(singleton);
        }
        return singletonNames;
    }
    return null;
}
