使用@Configuration注解class里面的@Autowired注入失败

Question

由于用的是spring io构建的maven项目，没有使用spring boot，有一些注入会失败，有一些是可以的。

应该是有个读取的先后顺序，网上没找到解决办法。

1. 如何解决

2. spring boot和直接用maven构建的项目区别在哪

请老师不吝赐教。感谢~

什么问题？没看懂，不管spring io，spring boot，不都是maven项目么，没明白想问啥。如何解决？你得把代码和错误贴上来我看一下啊...

  实例化TokenStoreConfig的时候，redisConnectionFactory注入失败。错误代码贴出来了，麻烦看一下。
