springboot能扫描到controller,页面访问不到
网页访问的错误为404 求大神帮忙解答~~ 万分感激

参考技术A

你路径没有些正确


你可以尝试一下最简单的跳转

你可以重新创建一个项目试试看看对比一下你就会发现问题了

最主要你的路径你自己写的太繁杂

SpringBoot中出现的错误

1.Field boy in com.huhu.SpringDemo.HelloController required a bean of type ‘com.huhu.SpringBean.Boy‘ that could not be found.

解决办法：

1.将这个类放到与Spring boot的启动类需要放在需要扫描类的上层目录，这样才能扫描到同级或者子类需要注册的类。 

2.在你使用的Controller上面加上@ComponentScan(basePackages="com.xx")，basePackages注意范围，太大不行，太耗时间了，太小扫描不到

 

2.There was an unexpected error (type=Internal Server Error, status=500).Circular view path [hello]: would dispatch back to the current handler URL [/boot/hello] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

解决办法：给Controller加上@Controller和@ResponseBody
