seata AT模式失效

在当前业务类,比如UserServiceImpl中使用UserService userService = ApplicationContext.getBean(UserService.class)后,为什么会导致本类中所有的@GlobalTransactional注解失效呀?seata版本是1.2.0 spring-boot版本2.2.2

Start from the UserServiceImpl scenario described in the issue and reproduce it with Seata 1.2.0 and Spring Boot 2.2.2. Investigate how ApplicationContext.getBean(UserService.class) interacts with @GlobalTransactional, then confirm the cause and document the expected behavior or fix; no source file or test is named.
