在one中实现InitializingBean接口呢? ~~~ public class one implements ApplicationContextAware ,InitializingBean { @Override public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { System.out.println("setApplicationContext"); } @Override public void afterPropertiesSet() throws Exception { System.out.println("afterPropertiesSet"); } public one(String one) { System.out.println(one); } } ~~~ 结果
