在spring项目中随时获取bean的方式

public class SpringContextUtils {
    private static ConfigurableApplicationContext AC = null;
    public static void setAc(ConfigurableApplicationContext ac){
        AC = ac;
    }
    public static <T> T getBean(String methodName, Class<T> beanClassType) {
        return AC.getBean(methodName, beanClassType);
    }
}

User user= SpringContextUtils.getBean("getName", User.class);
