新版SpringSecurity配置（SpringBoot＞2.7&SpringSecurity＞5.7）

新版SpringSecurityConfig

在使用SpringBoot2.7或者SpringSecurity5.7以上版本时，会提示：

在 Spring Security 5.7.0-M2 中，我们弃用了WebSecurityConfigurerAdapter，因为我们鼓励用户转向基于组件的安全配置。

所以之前那种通过继承WebSecurityConfigurerAdapter的方式的配置组件是不行的。

同时也会遇到很多问题，例如：

在向SpringSecurity过滤器链中添加过滤器时（例如：JWT支持，第三方验证），我们需要注入AuthenticationManager对象等问题。

故在此记录一下SpringSecurity的一些基础配置项：

1 网络安全配置，忽略部分路径（如静态文件路径）

@Bean
public WebSecurityCustomizer webSecurityCustomizer() {
     return (web) -> web.ignoring().antMatchers("/ignore1", "/ignore2");
}

2 设置中文配置

@Bean
public ReloadableResourceBundleMessageSource messageSource() {
    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    // 设置中文配置
    messageSource.setBasename("classpath:org/springframework/security/messages_zh_CN");
    return messageSource;
}

3 设置密码编码器

@Bean
@ConditionalOnMissingBean
public PasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
}

4 取消ROLE_ prefix

@Bean
@ConditionalOnMissingBean
public GrantedAuthorityDefaults grantedAuthorityDefaults() {
    // Remove the ROLE_ prefix
    return new GrantedAuthorityDefaults("");
}

5 暴露本地认证管理器（AuthenticationManager）

/**
 * 认证管理器，登录的时候参数会传给 authenticationManager
 */
@Bean(name = BeanIds.AUTHENTICATION_MANAGER)
public AuthenticationManager authenticationManager(AuthenticationConfiguration authenticationConfiguration) throws Exception {
    return authenticationConfiguration.getAuthenticationManager();
}
