java - 如何将弃用的 WebSecurityConfigurerAdapter 迁移到 SecurityFilterChain？

Question

正如他们对我们的描述 here ，WebSecurityConfigurerAdapter 将在一段时间内弃用。

由于我想实现 JWT 模式，我尝试使用 SecurityFilterChain 重构 WebSecurityConfigurerAdapter 的实现。我面临的主要考虑是配置返回无效。

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder);
}

@Override
protected void configure(HttpSecurity http) throws Exception {
    CustomAuthenticationFilter customAuthenticationFilter = new CustomAuthenticationFilter(authenticationManagerBean(), accessTokenExpiredInDays, refreshTokenExpiredInDays, jwtSecret);
    customAuthenticationFilter.setFilterProcessesUrl("/api/login");
    http
        .csrf().disable();
    http
        .sessionManagement()
            .sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    http
        .authorizeRequests()
            .antMatchers("/error").permitAll();
    http
        .authorizeRequests()
            .antMatchers("/api/login/**", "/api/token/refresh/**").permitAll();
    http
        .authorizeRequests()
            .anyRequest().authenticated();
    http
        .addFilter(customAuthenticationFilter);
    http
        .addFilterBefore(new CustomAuthorizationFilter(jwtSecret), UsernamePasswordAuthenticationFilter.class);
}

@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception{
    return super.authenticationManagerBean();
}

请注意，Spring Security 内置了对 JWT 身份验证的支持，无需创建自定义过滤器。您可以找到 Spring Security 团队提供的示例 here .

但是，如果您确实选择创建自定义过滤器，推荐的配置方法是创建 custom DSL .
这和 Spring Security 在内部做的方式是一样的。

我在下面使用自定义 DSL 重写了您的配置。

@Bean
public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
    http
        .csrf().disable();
    http
        .sessionManagement()
        .sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    http
        .authorizeRequests()
        .antMatchers("/error").permitAll();
    http
        .authorizeRequests()
        .antMatchers("/api/login/**", "/api/token/refresh/**").permitAll();
    http
        .authorizeRequests()
        .anyRequest().authenticated();
    // apply the custom DSL which adds the custom filter
    http
        .apply(customDsl());
    http
        .addFilterBefore(new CustomAuthorizationFilter(jwtSecret), UsernamePasswordAuthenticationFilter.class);

    return http.build();
}

public class MyCustomDsl extends AbstractHttpConfigurer<MyCustomDsl, HttpSecurity> {
    @Override
    public void configure(HttpSecurity http) throws Exception {
        AuthenticationManager authenticationManager =
                http.getSharedObject(AuthenticationManager.class);
        CustomAuthenticationFilter filter = 
                new CustomAuthenticationFilter(authenticationManager, accessTokenExpiredInDays, refreshTokenExpiredInDays, jwtSecret);
        filter.setFilterProcessesUrl("/api/login");
        http.addFilter(filter);
    }

    public static MyCustomDsl customDsl() {
        return new MyCustomDsl();
    }
}

此配置以及其他示例在 Spring blog post 中进行了描述关于从 WebSecurityConfigurerAdapter 迁移。
