有时候在代码中,不希望使用自动注入,而是手动获取Spring容器以及Spring容器中的某个对象
1、首先写一个class实现ApplicationContextAware#
import org.springframework.beans.BeansException; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware;@Component public class SpringBeanUtil implements ApplicationContextAware {private static ApplicationContext applicationContext;@Overridepublic void setApplicationContext(ApplicationContext applicationContext)throws BeansException {SpringBeanUtil.applicationContext = applicationContext;}/*** 通过名称在spring容器中获取对象* * @param beanName* @return*/public static Object getBean(String beanName) {return applicationContext.getBean(beanName);}}
2、在代码调用SpringBeanUtil的getBean获取指定的bean对象了
