在使用纯java配置时,我花了相当多的时间在弹簧安全性上。要使其正常工作,需要执行几个步骤。它应该是沿着这些路线的东西。基本流程如下:
- 创建自定义筛选器以检查对特定授权信息的请求 
- 每个筛选器返回 null(如果未找到该类型的授权),或自定义 AbstractAuthenticationToken 
- 如果筛选器返回一个令牌,则将调用每个身份验证提供程序的支持(类)方法,如果该令牌应尝试身份验证,则该令牌将返回 true|false 
- 然后,将在支持令牌的身份验证提供程序上调用尝试身份验证。在这里,您可以执行任何服务调用以对用户进行身份验证。然后,您可以抛出 LoginException 或调用 authentication.setAuthenticated(true),并返回令牌以成功进行身份验证。 
我一直在使用此设置一段时间,支持各种身份验证方法(签名请求,用户名/密码,oauth等),并且效果很好。
您还可以将身份验证成功处理程序和身份验证Failuers处理程序传递到自定义安全筛选器,以提供自定义重定向策略和故障处理。
此外,请务必在过滤器的构造函数中设置蚂蚁匹配器,以控制过滤器也应用的 url 模式。例如,ldap 请求过滤器可能需要与任何请求“/*”进行检查,而用户名/密码过滤器只需在 POST 的 /login 或类似内容上进行检查即可。
示例代码:
1) 为要支持的每种身份验证类型创建自定义身份验证令牌
public class LDAPAuthorizationToken extends AbstractAuthenticationToken {
    private String token;
    public LDAPAuthorizationToken( String token ) {
        super( null );
        this.token = token;
    }
    public Object getCredentials() {
        return token;
    }
    public Object getPrincipal() {
        return null;
    }
}
public class OTPAuthorizationToken extends UsernamePasswordAuthenticationToken {
    private String otp;
    public OTPAuthorizationToken( String username, String password, String otp ) {
        super( username, password );
        this.otp = otp;
    }
    public String getOTP() {
        return otp;
    }
}
2) 为每种类型的自定义安全筛选器
public class LDAPAuthorizationFilter extends AbstractAuthenticationProcessingFilter {
    @Autowired
    private UserDetailsService userDetailsService;
    public LDAPAuthorizationFilter() {
        super( "/*" ); // allow any request to contain an authorization header
    }
    public Authentication attemptAuthentication( HttpServletRequest request, HttpServletResponse response ) throws AuthenticationException
    {
        if ( request.getHeader( "Authorization" ) == null ) {
            return null; // no header found, continue on to other security filters
        }
        // return a new authentication token to be processed by the authentication provider
        return new LDAPAuthorizationToken( request.getHeader( "Authorization" ) );
    }
}
public class OTPAuthorizationFilter extends AbstractAuthenticationProcessingFilter {
    @Autowired
    private UserDetailsService userDetailsService;
    public OTPAuthorizationFilter() {
        super( "/otp_login" );
    }
    public Authentication attemptAuthentication( HttpServletRequest request, HttpServletResponse response ) throws AuthenticationException
    {
        if ( request.getParameter( "username" ) == null || request.getParameter( "password" ) == null || request.getParameter( "otp" ) == null ) {
            return null;
        }
        // return a new authentication token to be processed by the authentication provider
        return new OTPAuthorizationToken( request.getParameter( "username" ), request.getParameter( "password" ), request.getParameter( "otp" ) );
    }
}
3) 创建自定义身份验证提供程序
public class LDAPAuthenticationProvider implements AuthenticationProvider {
    @Autowired
    private MyAuthenticationService sampleService;
    @Override
    public Authentication authenticate( Authentication authentication ) throws AuthenticationException {
        LDAPAuthorizationToken auth = (LDAPAuthorizationToken)authentication;
        String username = sampleService.verifyToken( auth.getCredentials() );
        if ( username == null ) {
            throw new LoginException( "Invalid Token" );
        }
        auth.setAuthenticated( true );
        return auth;
    }
    @Override
    public boolean supports( Class<?> authentication ) {
        if ( authentication.isAssignableFrom( LDAPAuthorizationToken.class ) ) {
            return true;
        }
        return false;
    }
}
public class OTPAuthenticationProvider implements AuthenticationProvider {
    @Autowired
    private MyAuthenticationService sampleService;
    @Override
    public Authentication authenticate( Authentication authentication ) throws AuthenticationException {
        OTPAuthorizationToken auth = (OTPAuthorizationToken)authentication;
        String error = sampleService.loginWithOTP( auth.getPrincipal(), auth.getCredentials(), auth.getOTP() );
        if ( error != null ) {
            throw new LoginException( error );
        }
        auth.setAuthenticated( true );
        return auth;
    }
    @Override
    public boolean supports( Class<?> authentication ) {
        if ( authentication.isAssignableFrom( OTPAuthorizationToken.class ) ) {
            return true;
        }
        return false;
    }
}
4) 配置弹簧安全
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure( HttpSecurity http ) throws Exception {
        // configure filters
        http.addFilterBefore( new LDAPAuthorizationFilter(), UsernamePasswordAuthenticationFilter.class );
        http.addFilterBefore( new OTPAuthorizationFilter(), UsernamePasswordAuthenticationFilter.class );
        // configure authentication providers
        http.authenticationProvider( new LDAPAuthenticationProvider() );
        http.authenticationProvider( new OTPAuthenticationProvider() );
        // disable csrf
        http.csrf().disable();
        // setup security
        http.authorizeRequests()
            .anyRequest()
                .fullyAuthenticated()
                .and().httpBasic();
    }
}
希望有所帮助!
