SpringBoot 使用ApplicationContext 及 getbean的两种方式

第一种：容器加载时设置

public class ProxyApplication {
    public static void main(String[] args) {
        ApplicationContext applicationContext = SpringApplication.run(ProxyApplication.class, args);
        SpringContextUtil.setApplicationContext(applicationContext);
    }
}

实例化SpringContextUtil

public class SpringContextUtil {
 
    // Spring应用上下文环境
    private static ApplicationContext applicationContext;
 
    /**
     * 实现ApplicationContextAware接口的回调方法，设置上下文环境
     */
    public static void setApplicationContext(ApplicationContext applicationContext)throws BeansException  {
        SpringContextUtil.applicationContext = applicationContext;
    }
 
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }
 
    /**
     *  根据beanId返回Spring中的实例
     * @Date 2019-08-07 17:36
     * @param
     * @return
     **/
    public static Object getBean(String beanId) throws BeansException {
        return applicationContext.getBean(beanId);
    }
}

实现

AutoLogonConfig autoLogonConfig = (AutoLogonConfig) SpringContextUtil.getBean("autoLogonConfig");
