Javaの設定を使用して春にワッフルを設定する方法

Question

私は春4.2.5で動作するようにワッフルを取得するのに苦労しています。そして私は同じ状況で他人を助けるかもしれないと思った。

私たちはワッフルNTLMプロトコルで検証された後、ユーザーがデータベースに存在することを認証するカスタムpreWaffleおよびpostWaffleフィルターを使用します。

また、EnableGlobalMethodSecurityアノテーションを使用してユーザーアクションを承認する方法もあります。

春のJavaの設定でこれを動作させるには、問題を最小限に抑えることがいくつかありました。以下の答えで私たちの解決策を見つけることができます。私はそれが助けてくれることを願う

SpringConfiguration.java

// ... imports 
@Configuration 
@EnableWebMvc 
@EnableScheduling 
@PropertySources({ 
    @PropertySource("classpath:app.properties") 
    // ... Properties sources 
}) 
@EnableTransactionManagement 
@ComponentScan(basePackages = "com.our.package") 
public class SpringConfiguration extends WebMvcConfigurerAdapter { 

// Our Spring configuration ... 

} 

SecurityConfiguration.java

// ... imports 
@Configuration 
@EnableWebSecurity 
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, proxyTargetClass = true) 
@Order(1) 
public class SecurityConfiguration extends WebSecurityConfigurerAdapter{ 

    // Authentication manager configuration 
    @Autowired 
    private WindowsAuthenticationProviderWrapper authProvider; 

    @Autowired 
    private AuthenticationManagerBuilder auth; 

    @Override 
    protected void configure(final AuthenticationManagerBuilder auth) throws Exception { 
    auth.authenticationProvider(authProvider); 
    } 

    @Bean 
    public AuthenticationManager authenticationManager() throws Exception { 
    return auth.getObject(); 
    } 

    // Waffle configuration 
    @Bean 
    public Filter customPreAuthSecurityFilter() { 
    return new CustomPreAuthSecurityFilter(); 
    } 

    @Bean 
    public Filter customNegotiateSecurityFilter() { 
    return new CustomNegotiateSecurityFilter(); 
    } 

    @Bean 
    public WindowsAuthProviderImpl waffleAuthProvider(){ 
    return new WindowsAuthProviderImpl(); 
    } 

    @Bean(name="negotiateSecurityFilterProvider") 
    @Autowired 
    public NegotiateSecurityFilterProvider negotiateSecurityFilterProvider(){ 
    NegotiateSecurityFilterProvider bean = new NegotiateSecurityFilterProvider(waffleAuthProvider()); 
    List<String> protocols = new ArrayList<>(); 
    protocols.add("Negotiate"); 
    bean.setProtocols(protocols); 
    return bean; 
    } 

    @Bean 
    public BasicSecurityFilterProvider basicSecurityFilterProvider(){ 
    return new BasicSecurityFilterProvider(waffleAuthProvider()); 
    } 

    @Bean(name="waffleSecurityFilterProviderCollection") 
    @Autowired 
    public waffle.servlet.spi.SecurityFilterProviderCollection negotiateSecurityFilterProviderCollection() { 
    final List<SecurityFilterProvider> lsp = new ArrayList<>(); 
    lsp.add(negotiateSecurityFilterProvider()); 
    lsp.add(basicSecurityFilterProvider()); 
    return new waffle.servlet.spi.SecurityFilterProviderCollection(lsp.toArray(new SecurityFilterProvider[]{})); 
    } 

    @Bean(name="negotiateSecurityFilterEntryPoint") 
    @Autowired 
    public waffle.spring.NegotiateSecurityFilterEntryPoint negotiateSecurityFilterEntryPoint() { 
    final waffle.spring.NegotiateSecurityFilterEntryPoint ep = new waffle.spring.NegotiateSecurityFilterEntryPoint(); 
    ep.setProvider(negotiateSecurityFilterProviderCollection()); 
    return ep; 
    } 

    @Bean(name="negotiateSecurityFilter") 
    @Autowired 
    public waffle.spring.NegotiateSecurityFilter waffleNegotiateSecurityFilter(){ 
    waffle.spring.NegotiateSecurityFilter bean = new waffle.spring.NegotiateSecurityFilter(); 
    bean.setRoleFormat("both"); 
    bean.setPrincipalFormat("fqn"); 
    bean.setAllowGuestLogin(false); 
    bean.setProvider(negotiateSecurityFilterProviderCollection()); 
    return bean; 
    } 

    // Static Mappings 
    @Override 
    public void configure(WebSecurity web) throws Exception { 
    web.ignoring().antMatchers("/assets/**"); 
    } 

    // Security filter chain 
    // The custom filters can be removed if you only use waffle 
    // but this is how we added them 
    @Override 
    protected void configure(HttpSecurity http) throws Exception { 
    // A user needs to have the role user and has to be authenticated 
    http.exceptionHandling() 
     .authenticationEntryPoint(negotiateSecurityFilterEntryPoint()).and() 
     .addFilterBefore(customPreAuthSecurityFilter(), BasicAuthenticationFilter.class) 
     .addFilterAfter(waffleNegotiateSecurityFilter(), BasicAuthenticationFilter.class) 
     .addFilterAfter(customNegotiateSecurityFilter(), BasicAuthenticationFilter.class) 
     .authorizeRequests().anyRequest().fullyAuthenticated(); 
    } 
    } 

は、私は、次のwrapperclassを作成したワッフルauthProviderをautowireすることができるようにします。

WindowsAuthenticationProviderWrapper.java

// ... imports 
// This class purpose is only to make the Windows authentication provider autowireable in spring. 
@Component 
public class WindowsAuthenticationProviderWrapper extends WindowsAuthenticationProvider{}

EDIT

1つの実装です。 CustomServletRequestWrapper：あなたはより多くの情報が必要な場合

class CustomServletRequestWrapper extends HttpServletRequestWrapper { 


    public CustomServletRequestWrapper(HttpServletRequest request) { 
     super(request); 
    } 
    public String getHeader(String name) { 
     if(name.equals("Authorization")) 
      return null; 
     String header = super.getHeader(name); 
     return (header != null) ? header : super.getParameter(name); // Note: you can't use getParameterValues() here. 
    } 

    public Enumeration getHeaderNames() { 
     List<String> names = Collections.list(super.getHeaderNames()); 

     names.addAll(Collections.list(super.getParameterNames())); 
     names.remove("Authorization"); 
     return Collections.enumeration(names); 
    } 

}
