如何將棄用的 WebSecurityConfigurerAdapter 遷移到 SecurityFilterChain？

Question

正如他們在這里描述的那樣， WebSecurityConfigurerAdapter將在一段時間內被棄用。

由於我想實現 JWT 模式，我嘗試使用SecurityFilterChain重構WebSecurityConfigurerAdapter的實現。 我面臨的主要考慮是配置返回無效。

@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();
}

請注意，Spring Security 內置了對 JWT 身份驗證的支持，無需創建自定義過濾器。 您可以在此處找到 Spring Security 團隊提供的示例。

但是，如果您確實選擇創建自定義過濾器，推薦的配置方法是創建自定義 DSL 。
這與 Spring Security 在內部執行的方式相同。

我在下面使用自定義 DSL 重寫了您的配置。

@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有關從WebSecurityConfigurerAdapter遷移的 Spring 博客文章中進行了描述。
