spring boot中使用security样例抛异常,Circular view path跳转失败

参考官方spring-security样例,项目启动后访问任意url,访问报错

页面显示错误:

Tue Mar 27 11:22:42 CST 2018

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.)

后台报错:

原因: 查看后发现,样例模板为thymeleaf

而本项目中未引进thymeleaf视图解析器,使用的是默认的视图解析器.

解决方法  : 引入thymeleaf与spring boot 集成jar包即可

   org.springframework.boot
   spring-boot-starter-thymeleaf
