springboot INFO

[noahlin27]

o.s.c.a.ConfigurationClassEnhancer : @Bean method SwaggerAutoConfiguration.docketBeanFactoryPostProcessor is non-static and returns an object assignable to Spring's BeanFactoryPostProcessor interface. This will result in a failure to process annotations such as @Autowired, @Resource and @PostConstruct within the method's declaring @Configuration class. Add the 'static' modifier to this method to avoid these container lifecycle issues; see @Bean javadoc for complete details.

Thank you for your reminding. We will read and verify your suggestions carefully

[llin6025]

I can not get this Info level of information using 2.0, can you add a scenario?

[noahlin27]

I'm using Spring Boot v2.5.3. What do you mean by 'scenario'? 直接用中文告诉我吧hxd

[llin6025]

@noahlin27 如果有问题，希望这对问题做一下描述，并给出相关的环境信息、Demo等，用于重现问题和定位，开源社区大家更希望针对问题去处理，而不是探索如何去重现。 这里可以使用 static 屏蔽掉这个 INFO 提示信息，不过我更好奇这引发了什么样的问题。 SwaggerAutoConfiguration 功能单一，并且不存在相关注解的使用。 备注相关说明：docs.spring.io

我也遇到了同样的信息，然后后面的swagger启动就报错了。我的工程中，集成了druid的监控、异步线程等。报错信息：
