package com.shaoming.utils; import org.springframework.beans.BeansException; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; import org.springframework.stereotype.Component; /** * @Auther: shaoming * @Date: 2020/10/20 16:07 * @Description: */ /** * spring 上下文工具类 * @author xiejianwei */ @Component public class ApplicationContextUtil implements ApplicationContextAware { /** * 上下文对象实例 */ private static ApplicationContext applicationContext; @Override public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { ApplicationContextUtil.applicationContext = applicationContext; } /** * 获取applicationContext * * @return */ public static ApplicationContext getApplicationContext() { return applicationContext; } /** * 通过name获取 Bean. * * @param name * @return */ public static Object getBean(String name) { return getApplicationContext().getBean(name); } /** * 通过class获取Bean. * * @param clazz * @param <T> * @return */ public static <T> T getBean(Class<T> clazz) { return getApplicationContext().getBean(clazz); } /** * 通过name,以及Clazz返回指定的Bean * * @param name * @param clazz * @param <T> * @return */ public static <T> T getBean(String name, Class<T> clazz) { return getApplicationContext().getBean(name, clazz); } }

说明:

可以工具id和类名获取spring工厂中的javabean
