# Spring boot+Security OAuth2 自定义登录和授权页面 #

1. 依赖

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

`thymeleaf` 配置

spring:
    	thymeleaf:
        	prefix: classpath:/views/
        	suffix: .html
        	cache: false

2. 前端页面

自定义登录页面肯定要有自己的页面，先从页面入手，在resources 目录下新建views 目录，在此目录下新建base-login.html 文件如下：

<!DOCTYPE html>
    <html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">
    <head>
        <meta charset="UTF-8">
        <title>登录</title>
    </head>
    
    <style>
        .login-container {
            margin: 50px;
            width: 100%;
        }
    
        .form-container {
            margin: 0px auto;
            width: 50%;
            text-align: center;
            box-shadow: 1px 1px 10px #888888;
            height: 300px;
            padding: 5px;
        }
    
        input {
            margin-top: 10px;
            width: 350px;
            height: 30px;
            border-radius: 3px;
            border: 1px #E9686B solid;
            padding-left: 2px;
    
        }
    
    
        .btn {
            width: 350px;
            height: 35px;
            line-height: 35px;
            cursor: pointer;
            margin-top: 20px;
            border-radius: 3px;
            background-color: #E9686B;
            color: white;
            border: none;
            font-size: 15px;
        }
    
        .title{
            margin-top: 5px;
            font-size: 18px;
            color: #E9686B;
        }
    </style>
    <body>
    <div class="login-container">
        <div class="form-container">
            <p class="title">用户登录</p>
            <form name="loginForm" method="post" th:action="${loginProcessUrl}">
                <input type="text" name="username" placeholder="用户名"/>
                <br>
                <input type="password" name="password" placeholder="密码"/>
                <br>
                <button type="submit" class="btn">登    录</button>
            </form>
            <p style="color: red" th:if="${param.error}">用户名或密码错误</p>
        </div>
    </div>
    </body>
    </html>

在views文件夹下新建base-grant.html 授权页面文件，如下所示

<!DOCTYPE html>
    <html lang="en" xmlns:th="http://www.thymeleaf.org">
    <head>
        <meta charset="UTF-8">
        <title>授权</title>
    </head>
    <style>
    
        html{
            padding: 0px;
            margin: 0px;
        }
    
        .title {
            background-color: #E9686B;
            height: 50px;
            padding-left: 20%;
            padding-right: 20%;
            color: white;
            line-height: 50px;
            font-size: 18px;
        }
        .title-left{
            float: right;
        }
        .title-right{
            float: left;
        }
        .title-left a{
            color: white;
        }
        .container{
            clear: both;
            text-align: center;
        }
        .btn {
            width: 350px;
            height: 35px;
            line-height: 35px;
            cursor: pointer;
            margin-top: 20px;
            border-radius: 3px;
            background-color: #E9686B;
            color: white;
            border: none;
            font-size: 15px;
        }
    </style>
    <body style="margin: 0px">
    <div class="title">
        <div class="title-right">OAUTH-BOOT 授权</div>
        <div class="title-left">
            <a href="#help">帮助</a>
        </div>
    </div>
        <div class="container">
             <h3 th:text="${clientId}+' 请求授权，该应用将获取你的以下信息'"></h3>
            <p>昵称，头像和性别</p>
             授权后表明你已同意 <a  href="#boot" style="color: #E9686B">OAUTH-BOOT 服务协议</a>
            <form method="post" action="/oauth/authorize">
                <input type="hidden" name="user_oauth_approval" value="true">
                <input type="hidden" name="_csrf" th:value="${_csrf.getToken()}"/>
                <button class="btn" type="submit"> 同意/授权</button>
            </form>
        </div>
    </body>
    </html>

3. Controller

登录页面controller如下

@Controller
    public class BaseMainController {
        @Autowired
        private BootSecurityProperties properties;
    
        @GetMapping("/auth/login")
        public String loginPage(Model model){
            model.addAttribute("loginProcessUrl",properties.getLoginProcessUrl());
            return "base-login";
        }
    }

4. `WebSecurity` 配置

授权前的用户认证有Security 提供，将自定义的登录页面配置进去

@Configuration
    @Order(1)
    public class SecurityConfig extends WebSecurityConfigurerAdapter {
    
        @Autowired
        private BootUserDetailService userDetailService;
    
        @Autowired
        private BootSecurityProperties properties;
    
        /**
         * 让Security 忽略这些url，不做拦截处理
         *
         * @param
         * @throws Exception
         */
        @Override
        public void configure(WebSecurity web) throws Exception {
            web.ignoring().antMatchers
                    ("/swagger-ui.html/**", "/webjars/**",
                            "/swagger-resources/**", "/v2/api-docs/**",
                            "/swagger-resources/configuration/ui/**", "/swagger-resources/configuration/security/**",
                            "/images/**");
        }
    
        @Override
        public void configure(AuthenticationManagerBuilder auth) throws Exception {
            auth.userDetailsService(userDetailService);
        }
    
        @Override
        protected void configure(HttpSecurity http) throws Exception {
    
            http
                    // 必须配置，不然OAuth2的http配置不生效----不明觉厉
                    .requestMatchers()
                    .antMatchers("/auth/login", properties.getLoginProcessUrl(), "/oauth/authorize")
                    .and()
                    .authorizeRequests()
                    // 自定义页面或处理url是，如果不配置全局允许，浏览器会提示服务器将页面转发多次
                    .antMatchers("/auth/login", properties.getLoginProcessUrl())
                    .permitAll()
                    .anyRequest()
                    .authenticated();
            
            // 表单登录
            http.formLogin()
                    // 登录页面
                    .loginPage("/auth/login")
                    // 登录处理url
                    .loginProcessingUrl(properties.getLoginProcessUrl());
        }
    
        @Override
        @Bean
        public AuthenticationManager authenticationManagerBean() throws Exception {
            return super.authenticationManagerBean();
        }
    
        @Bean
        public PasswordEncoder passwordEncoder() {
            return new BCryptPasswordEncoder();
        }
    }

到这里已经完成了自定义登录页的功能，接下来继续说自定义授权页面

5. 自定义授权页面

自定义授权页面的方式有两种，分别如下；

（1）. 直接定义如下controller 替换原来的授权controller

@Controller
    // 必须配置
    @SessionAttributes("authorizationRequest")
    public class BootGrantController {
    
        @RequestMapping("/oauth/confirm_access")
        public ModelAndView getAccessConfirmation(Map<String, Object> model, HttpServletRequest request) throws Exception {
            AuthorizationRequest authorizationRequest = (AuthorizationRequest) model.get("authorizationRequest");
            ModelAndView view = new ModelAndView();
            view.setViewName("base-grant");
            view.addObject("clientId", authorizationRequest.getClientId());
            return view;
        }
    }

（2）. 在认证服务配置文件中添加如下配置

@Configuration
    @EnableAuthorizationServer
    public class OAuth2AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
    
    	......
    	
        @Override
        public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        	......
        	// 最后一个参数为替换之后页面的url
            endpoints.pathMapping("/oauth/confirm_access","/custom/confirm_access");
        }
    }

之后编写对应的controller实现即可

6. 测试

最终效果如下
