java - 所有 Spring-Boot 应用程序始终显示弹出登录信息

Question

我使用 Spring 和 Spring Boot 框架与 Spring Security 来实现具有简单 UI 的简单登录项目。在我所有的项目中，使用 STS，启动我的应用程序并运行本地主机地址而没有错误后，我收到一个弹出登录窗口，而不是我的 html 页面。如果我使用用户和默认安全密码，我总是会得到一个白标错误页面作为结果。此外，如果我使用不正确的值，弹出窗口仍然存在，如果我使用默认访问值，我会收到此消息。

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

这是一个简单的项目代码。所有 html 文件都位于模板文件夹中，正如您在项目结构中看到的那样。我还尝试在我的 application.properties 文件中使用 server.error.whitelabel.enabled=false。`

为什么html界面一直没有显示出来？

Project Structure

应用

package com.cyberdemon.springboot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringbootUiLoginApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootUiLoginApplication.class, args);
    }
}

安全配置

package config;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
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.configuration.WebSecurityConfigurerAdapter;

@Configuration
@EnableAutoConfiguration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    DataSource dataSource;

    @Autowired
    public void configAuthentication(AuthenticationManagerBuilder auth) throws Exception {
        auth.jdbcAuthentication().dataSource(dataSource)
                .usersByUsernameQuery("select username,password, enabled from users where username=?")
                .authoritiesByUsernameQuery("select username, role from user_roles where username=?");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/", "/home").permitAll().antMatchers("/admin").hasRole("ADMIN")
                .anyRequest().authenticated().and().formLogin().loginPage("/login").permitAll().and().logout()
                .permitAll();
        http.exceptionHandling().accessDeniedPage("/403");
    }

}

Web Controller

package controller;

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

@Controller
public class WebController {

    @RequestMapping(value = { "/", "home" })
    public String home() {
        return "home";
    }

    @RequestMapping(value = { "/welcome" })
    public String welcome() {
        return "welcome";
    }

    @RequestMapping(value = "/admin")
    public String admin() {
        return "admin";
    }

    @RequestMapping(value = { "/login" })
    public String login() {
        return "login";
    }

    @RequestMapping(value = "/403")
    public String Error403() {
        return "403";
    }

}

Answer 1

您需要重组您的包，使其位于 SpringbootUiLoginApplication 的包下，或者使用 @ComponentScan 告诉 Spring Boot 在哪里可以找到您的 bean 类。
