Spring Security 自定义 html 登录页面未呈现 [英] Spring security custom html login page not rendered

问题描述

我已按照此 link 进行所有配置以设置我的自定义 html 的链接登录页面.但是，当我访问 localhost/login 时，我遇到了错误状态 500.

i have followed this link for all configurations to set link up my custom html page for login. However, when i access localhost/login, i am faced with error status 500.

当我访问 localhost:8080/login 时，我无法呈现一个简单的 html 页面.

I am unable to render a simple html page when I access localhost:8080/login.

1. 是否需要额外配置?
2. html 页面应该位于模板文件夹中吗?应用程序如何知道它应该呈现login.html"??
3. 我的控制者是否被识别?

配置

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@EnableWebSecurity
@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {


    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                    .anyRequest().fullyAuthenticated()
                    .and()
                .formLogin()
                    .loginPage("/login")
                    .permitAll();

    }

}

控制器.

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class LoginController {

    @GetMapping("/login")
    public String login() {
        return "login";
    }
}

替换登录"上面和下面也显示错误.

replacing "login" above with below also shows error.

login.html 位于模板中.错误信息:

login.html is located in templates. error message:

javax.servlet.ServletException: 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.)

推荐答案

我已经设法解决了这个问题.主要问题是因为我的 artefactID 也被命名为 login.这导致了登录"的所有其他上下文，包括login.html".被作废.我将我的控制器修改为下面并将我的 html 文件更改为 login2.html 它可以工作.

I have managed to resolve this. The main issue was because my artefactID was also named login. This resulted in all other context of "login", including "login.html" to be voided. I modified my controller to below and changing my html file to login2.html it worked.

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class LoginController {

    @GetMapping("/login")
    public String login2() {
        return "login2";
    }
}
