参考[官方spring-security样例][spring-security],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

![70][]

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

<dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>
