SpringBoot实现其他普通类调用Spring管理的Service,dao等bean

@Component  
public class SpringUtils implements ApplicationContextAware {  
    private static ApplicationContext applicationContext = null;  
    @Override  
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {  
        if(SpringUtils.applicationContext == null){  
            SpringUtils.applicationContext  = applicationContext;  
        }  
    }  
 
    //获取applicationContext  
    public static ApplicationContext getApplicationContext() {  
        return applicationContext;  
    }  
 
    //通过name获取 Bean.  
    public static Object getBean(String name){  
        return getApplicationContext().getBean(name);  
    }  
 
    //通过class获取Bean.  
    public static <T> T getBean(Class<T> clazz){  
        return getApplicationContext().getBean(clazz);  
    }  
 
    //通过name,以及Clazz返回指定的Bean  
    public static <T> T getBean(String name,Class<T> clazz){  
        return getApplicationContext().getBean(name, clazz);  
    }  
}
