在本教程中，我将指导您如何编写代码，以使用具有基于表单的身份验证的Spring安全API来保护Spring Boot应用程序中的网页。用户详细信息存储在MySQL数据库中，并使用春季JDBC连接到数据库。我们将从[本教程][Link 1]中的 ProductManager 项目开始，向现有的弹簧启动项目添加登录和注销功能。

### **1. 创建用户表和虚拟凭据** ###

凭据应存储在数据库中，因此让我们创建新表，表间关系ER图如下：

    /*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */;
    /*!40111 SET SQL_NOTES=IFNULL(@OLD_SQL_NOTES, 1) */;

### **2. 配置数据源属性** ###

接下来，在应用程序属性文件中指定数据库连接信息，如下所示：根据您的MySQL数据库更新URL，用户名和密码。

spring.jpa.hibernate.ddl-auto=update
    spring.datasource.url=jdbc:mysql://localhost:3306/product3?autoReconnect=true&useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
    spring.datasource.username=root
    spring.datasource.password=root
    #logging.level.root=WARN

### **3. 声明弹簧安全性和 MySQL JDBC 驱动程序的依赖关系** ###

要将Spring安全API用于项目，请在pom.xml文件中声明以下依赖项：并且要将JDBC与弹簧启动和MySQL一起使用：请注意，依赖项版本已由弹簧启动初学者父项目定义。

### **4. 配置 JDBC 身份验证详细信息** ###

要将 Spring 安全性与基于表单的身份验证和 JDBC 结合使用，请按如下方式创建 WebSecurityConfig 类：

不适用已废弃的WebSecurityConfigurerAdapter

package com.example;
    
    import javax.sql.DataSource;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.security.authentication.AuthenticationManager;
    import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
    import org.springframework.security.config.annotation.authentication.configuration.AuthenticationConfiguration;
    import org.springframework.security.config.annotation.web.builders.HttpSecurity;
    import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
    import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
    import org.springframework.security.web.SecurityFilterChain;
    
    @Configuration
    @EnableWebSecurity
    public class WebSecurityConfig {
    
        @Autowired
        private LoginSuccessHandler loginSuccessHandler;
        @Autowired
        private CustomLoginFailureHandler loginFailureHandler;
    
        @Autowired
        private DataSource dataSource;
    
    //    @Bean
    //    @Override
    //    public AuthenticationManager authenticationManagerBean() throws Exception {
    //        return super.authenticationManagerBean();
    //    }
        @Bean
        public AuthenticationManager authenticationManager(
                AuthenticationConfiguration authenticationConfiguration) throws Exception {
            return authenticationConfiguration.getAuthenticationManager();
        }
    
        @Bean
        BCryptPasswordEncoder bCryptPasswordEncoder() {
            return new BCryptPasswordEncoder();
        }
    
        @Autowired
        public void configAuthentication(AuthenticationManagerBuilder authBuilder) throws Exception {
            authBuilder.jdbcAuthentication()
                    .dataSource(dataSource)
                    .passwordEncoder(new BCryptPasswordEncoder())
                    .usersByUsernameQuery("select username, password, enabled from user where username=?")
                    .authoritiesByUsernameQuery("SELECT user.username,permission.name FROM user,role,user_role,permission,role_permission WHERE user.id=user_role.user_id AND role.id=user_role.role_id AND role.id=role_permission.role_id AND permission.id=role_permission.permission_id  AND user.username=?");
        }
    
    //    protected void configure(HttpSecurity http) throws Exception {
    //        http.authorizeRequests()
    //                .antMatchers("/webjars/**").permitAll()
    //                .antMatchers("/common/**").permitAll()
    //                .antMatchers("/login").permitAll()
    //                .antMatchers("/logout").permitAll()
    //                .antMatchers("/verify").permitAll()
    //                .antMatchers("/home").authenticated()
    //                .antMatchers("/user/info").authenticated()

    //                .antMatchers("/new/password").authenticated()
    //                .anyRequest()
    //                .access("@rbacService.hasPermission(request , authentication)")
    //                .and()
    //                .formLogin().loginPage("/login")
    //                .successHandler(loginSuccessHandler)
    //                .failureHandler(loginFailureHandler)
    //                .permitAll()
    //                .and()
    //                .logout().permitAll()
    //                .and()
    //                .exceptionHandling().accessDeniedPage("/403");
    //    }
        @Bean
        protected SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
            http.authorizeRequests()
                    .antMatchers("/webjars/**").permitAll()
                    .antMatchers("/common/**").permitAll()
                    .antMatchers("/login").permitAll()
                    .antMatchers("/logout").permitAll()
                    .antMatchers("/verify").permitAll()
                    .antMatchers("/home").authenticated()
                    .antMatchers("/user/info").authenticated()
                    .antMatchers("/change/password").authenticated()
                    .antMatchers("/new/password").authenticated()
                    .anyRequest()
                    .access("@rbacService.hasPermission(request , authentication)")
                    .and()
                    .formLogin().loginPage("/login")
                    .successHandler(loginSuccessHandler)
                    .failureHandler(loginFailureHandler)
                    .permitAll()
                    .and()
                    .logout().permitAll()
                    .and()
                    .exceptionHandling().accessDeniedPage("/403");
    
            return http.build();
        }
    
    }

此安全配置类必须使用@EnableWebSecurity注释进行批注，并且是 Web 安全配置器适配器的子类。数据源对象的实例将由Spring框架创建并注入：

@Autowired
        private DataSource dataSource;

它将从应用程序属性文件中读取数据库连接信息。要使用JDBC配置身份验证，请编写以下方法：

@Autowired
        public void configAuthentication(AuthenticationManagerBuilder authBuilder) throws Exception {
            authBuilder.jdbcAuthentication()
                    .dataSource(dataSource)
                    .passwordEncoder(new BCryptPasswordEncoder())
                    .usersByUsernameQuery("select username, password, enabled from users where username=?")
                    .authoritiesByUsernameQuery("SELECT users.username,permissions.name FROM users,roles,users_roles,permissions,roles_permissions WHERE users.username=users_roles.username AND roles.name=users_roles.role_name AND roles.name=roles_permissions.role_name AND permissions.name=roles_permissions.permission AND users.username=?");
        }

如您所见，我们需要指定密码编码器（建议使用BCrypt），数据源和两个SQL语句：第一个根据用户名选择用户，第二个选择用户的角色。请注意，Spring安全性要求列名必须是用户名，密码，启用和角色。为了配置基于表单的身份验证，我们重写了 configure（HttpSecurity） 方法，如下所示：

@Override
        protected void configure(HttpSecurity http) throws Exception {
            http.authorizeRequests()
                    .antMatchers("/edit/*", "/delete/*").hasAnyAuthority("ADMIN")
                    .anyRequest().authenticated()
                    .and()
                    .formLogin().permitAll()
                    .and()
                    .logout().permitAll()
                    .and()
                    .exceptionHandling().accessDeniedPage("/403");
        }

在这里，我们指定所有请求都必须进行身份验证，这意味着用户必须登录才能使用该应用程序。使用Spring安全性提供的默认登录表单。要显示已登录用户的用户名，请在Thymeleaf模板文件中编写以下代码：

<div sec:authorize="isAuthenticated()">
                    Welcome <b><span sec:authentication="name">Username</span></b>
                     
                    <i><span sec:authentication="principal.authorities">Roles</span></i>
                </div>

并添加注销按钮：

如您所见，Spring Security将处理应用程序的登录和注销。我们不必编写重复的代码，只需指定一些配置即可。

### **5. 测试登录和注销** ###

启动Spring Boot应用程序并访问 http://localhost:8080 在Web浏览器中，您将看到自定义的登录页面出现：

![74d9c55b07d845dc8916c07636499a6f.png][]

现在输入正确的用户名admin和密码admin，您将看到主页如下：

![1a1e61bb79504dd4b3030951d3888e3e.png][]

并注意欢迎消息后跟用户名。用户现在已通过身份验证以使用该应用程序。单击“注销”按钮，您将看到自定义的登录页面出现，这意味着我们已成功实现登录并注销到我们的Spring Boot应用程序。
