SpringBoot学习之启动报错【This application has no explicit mapping for /error.....】
今天做SpringBoot小例子,在请求controller层的时候出现如下问题。
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
问题很像是没有访问地址不对,第一感觉以为url写的不对。
其实不是,真正的原因是【Application启动类放的位置不对】要将Application放在最外层,也就是要包含所有子包。
比如你的groupId是com.google,子包就是所谓的com.google.xxx,所以要将Application类要放在com.google包下。
springboot会自动加载启动类所在包下及其子包下的所有组件.
