3、錯誤三
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Tue Aug 08 16:06:33 CST 2017 There was an unexpected error (type=Internal Server Error, status=500). Circular view path [login]: would dispatch back to the current handler URL [/login] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.) （頁面轉發的錯誤）解決辦法：缺少該jar
並配置：
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html

Tue Aug 08 16:26:34 CST 2017 There was an unexpected error (type=Internal Server Error, status=500). Exception parsing document: template="home", line 19 - column 3解決方法： 一般是模板頁面出錯了，一些標籤未關閉 例如 ：
