SpringBoot与Web

先在idea中选择场景
springboot已经默认将这些常见配置好了，我们只需要在配置文件中指定少量配置就可以运行起来
然后我们可以开始编写业务代码了

如何编写

理清依赖

自动配置

@Configuration 指定这个是配置类
@ConditionalOnxxx 在某些条件下才生效
@AutoConfigureAfter 指定自动配置类的顺序
@Bean 给IOC加组件
@ConfiguretionProperties 结合相关的xxxProperties配置类来绑定配置
@EnableConfigurationProperties 让xxxProperties生效加入到容器中
讲自动配置类配置在META-INF/spring.factories中

注意事项

对于所有的容器化开发，我们的时区都需要设置

-v /etc/localtime:/etc/localtime
