Spring-ApplicationContext registerBean自动装配失败，但getBean在Spring 5中工作

可能是因为您正在上下文初始化阶段的中间注册您的bean。如果您的目标Bean进行了初始化并

ExecutorService

ConfigClass

@PostConstruct

您可以尝试强制初始化顺序：

@Component@DependsOn("configClass")public class MyComponent  @Autowired  private ExecutorService executorService;

但是这将是清洁使用注册一个bean定义

BeanFactoryPostProcessor

BeanDefinitionBuilder

@Componentpublic class MyBeanRegistration implements BeanFactoryPostProcessor {  @Override  public void postProcessBeanFactory(ConfigurableListableBeanFactory bf) {    BeanDefinitionRegistry reg = (BeanDefinitionRegistry) bf;    reg.registerBeanDefinition("exService",      BeanDefinitionBuilder        .rootBeanDefinition(ExecutorService.class)        .setFactoryMethod("newWorkStealingPool")        .getBeanDefinition());  }}
