Spring的内部方法调用时，AOP切面失效问题解决

基于SpringBoot

场景：A方法调用内部B方法，需要切B方法

1，新建工具类SpringContextUtil实现ApplicationContextAware接口，@Component交给容器管理

@Component
public class SpringContextUtil implements ApplicationContextAware {
    private static ApplicationContext applicationContext;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        SpringContextUtil .applicationContext = applicationContext;
    }

    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    public static Object getBean(String name) throws BeansException {
        return applicationContext.getBean(name);
    }

    public static <T> T getBeanByClass(Class<T> cls) throws BeansException {
        return applicationContext.getBean(cls);
    }
}

2，调用内部方法时写法

// 注入当前Bean使得调用内部方法也被SpringAOP拦截
UserService service = SpringContextUtil.getBean(this.getClass());
User user = service .selectById(id);
