启动spring boot然后访问页面的时候，出现如下错误：
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available发现是配置出错了！
spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp应该改为
spring.view.prefix=/WEB-INF/jsp/
spring.view.suffix=.jsp。
