}

 

 可以看到这个地方报错，笔者以为是idea的问题，所以强行启动，也还是报错，

仔细阅读了下，错误：

Could not autowire. No beans of ‘int‘ type found. less... (Ctrl+F1)  Checks autowiring problems in a bean class.

 

这个bean无法被注入，代表这个bean是被spring管理的，然后post无法找到，

这个bean初始化的时候需要传入参数，所有spring是无法找到这个参数，所以报了这个错，

那么解决方法：首先，看你这个bean是否想被spring管理，如果不想，那么就就行将注解除去就好如果想被管理，那么就可以额加上，然后添加这个值
