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
错误写法1：
<a th:href="register.html">注册</a>
错误写法2:
<a href="register.html">注册</a>
正确写法：
<a th:href="@{register}">注册</a>
并且！！！！！！直接通过超链接跳转是成功不了的。
在Controller增加了后台处理方法，直接返回html：
@RequestMapping("/register")
public String toRegister(){
return "register";
}
注意：
1. 要用RequestMapping
2. application.properties中有关配置如下：
## thymeleaf spring.thymeleaf.mode=HTML5 spring.thymeleaf.encoding=UTF-8 spring.thymeleaf.servlet.content-type=text/html spring.thymeleaf.cache=false spring.thymeleaf.prefix=classpath:/templates/ spring.thymeleaf.suffix=.html spring.thymeleaf.check-template-location=true
