It looks like for some reason it is not resolving the login page but even though the login page is at the correct location. If I point to the users.html page that page loads and there are no errors. Must be something very simple I'm missing out on. Can someone please assist?
看起来由于某种原因它没有解析登录页面，但即使登录页面位于正确的位置。如果我指向该页面加载的 users.html 页面并且没有错误。一定是我错过的非常简单的东西。有人可以帮忙吗？
The following are my config classes:
以下是我的配置类：

Maybe you have a conflict with the resolvers of thymeleaf and springSecurity. You have set your loginPage configuration as 'login' and thymeleaf is expecting 'login.html'. Have you tried to change .loginPage("/login") for .loginPage("/login.html") ?
可能你和 thymeleaf 和 springSecurity 的解析器有冲突。您已将 loginPage 配置设置为“login”，而 thymeleaf 需要“login.html”。您是否尝试将 .loginPage("/login") 更改为 .loginPage("/login.html") ？

Just remove the suffix code from config.
只需从配置中删除后缀代码即可。
resolver.setSuffix(".html");
回答by user7149261
In the ThymeleafProperties class that the default prefix for views is classpath:/templates/and the default suffix is .html. So change your htmlto src/main/resources/templates/login.html, as shown in the following image
在 ThymeleafProperties 类中，视图的默认前缀是classpath:/templates/，默认后缀是.html. 因此，将您的更改html为src/main/resources/templates/login.html，如下图所示
