spring security2.7

在Spring Security 2.7及以上版本中，WebSecurityConfigurerAdapter已经被废弃。相反，现在推荐使用bean注入的方式进行配置。你可以参考官方文档：https://spring.io/blog/2022/02/21/spring-security-without-the-websecurityconfigureradapter#ldap-authentication 来了解更多详细信息。在SecurityConfig中，加载SpringSecurityAdminConfig即可。你可以使用@EnableWebSecurity注解来启用Web安全配置。在SecurityConfig类中，通过@Resource注解注入SpringSecurityAdminConfig，并通过@Bean注解创建SecurityFilterChain bean。在configure(HttpSecurity http)方法中，你可以通过以下代码配置安全性：

http
    .csrf(AbstractHttpConfigurer::disable) //禁用CSRF保护
    .sessionManagement(AbstractHttpConfigurer::disable) //禁用Session管理
    .authorizeHttpRequests(auhtor-> auhtor
        .antMatchers("/admin/code","/admin/login").permitAll() //设置允许匿名访问的URL
        .anyRequest().authenticated() //其余请求需要认证
    );
http.apply(springSecurityAdminConfig); //应用SpringSecurityAdminConfig配置
return http.build();

然后，你需要创建一个名为SpringSecurityAdminConfig的配置类，该类用于管理后台的用户名和密码登录。你可以参考以下示例代码：

@Component
public class SpringSecurityAdminConfig extends SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity> {
    @Override
    public void configure(HttpSecurity http) throws Exception {
        AdminUsernamePasswordAuthenticationFilter adminUsernamePasswordAuthenticationFilter = new AdminUsernamePasswordAuthenticationFilter();
        adminUsernamePasswordAuthenticationFilter.setAuthenticationManager(http.getSharedObject(AuthenticationManager.class));
        http.addFilterAt(adminUsernamePasswordAuthenticationFilter, UsernamePasswordAuthenticationFilter.class); //替换UsernamePasswordAuthenticationFilter
    }
}

这样就可以通过bean注入的方式配置Spring Security 2.7及以上版本了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
