Spring安全-自定义过滤器

Question

我正在使用这个环境：

• Spring 4.0.5
• Spring security 3.2.4

在我的环境中，我有一个SSO系统，我需要在这个系统中集成我的web应用程序。这个系统是私人产品。SSO机制的最终结果是在请求头中放置一个参数。所以我在申请中应该做的是：

null

此场景类似于CAS集成场景；所以我从CAS集成着手；我写了我的自定义过滤器，我写了我的自定义入口点和处理请求所需的所有其他类，但我面临一些问题；现在我可以在spring上下文中进行身份验证，但是在经过身份验证之后，就像没有经过身份验证一样。也许我漏掉了什么。

我将报告所有涉及的类和安全上下文。

我的自定义筛选器

public class WebSealAuthenticationFilter extends AbstractAuthenticationProcessingFilter
{
    protected WebSealAuthenticationFilter(RequestMatcher requiresAuthenticationRequestMatcher)
    {
        super(requiresAuthenticationRequestMatcher);
    }

    private static final Log logger = LogFactory.getLog(WebSealAuthenticationFilter.class.getName());

    @Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException, IOException, ServletException
    {
        WebSealIvUserNameAuthenticationToken auth = new WebSealIvUserNameAuthenticationToken(request.getHeader(WebSealRequestMatcher.DEFAULT_HEADER_PARAM));
        auth.setDetails(this.authenticationDetailsSource.buildDetails(request));
        return this.getAuthenticationManager().authenticate(auth);
    }

    @Override
    protected final void successfulAuthentication(HttpServletRequest request, HttpServletResponse response, FilterChain chain, Authentication authResult) throws IOException, ServletException
    {
        if (logger.isDebugEnabled()) {
            logger.debug("Authentication success. Updating SecurityContextHolder to contain: " + authResult);
        }

        SecurityContextHolder.getContext().setAuthentication(authResult);

        // Propaga l'evento
        if (this.eventPublisher != null) {
            eventPublisher.publishEvent(new InteractiveAuthenticationSuccessEvent(authResult, this.getClass()));
        }
        request.getSession().setAttribute("autenticato", new Boolean(true));
        chain.doFilter(request, response);
    }
}

我的请求匹配器（我知道我可以使用org.springframework.security.web.util.matcher.RequestHeaderRequestMatcher类，以后我将使用它）

public class WebSealRequestMatcher implements RequestMatcher
{
    public static final String DEFAULT_HEADER_PARAM = "iv-user";
    @Override
    public boolean matches(HttpServletRequest request)
    {
        String headerParam = request.getHeader(DEFAULT_HEADER_PARAM);
        return !StringUtils.hasText(headerParam);
    }   
}

我的AuthenticationProvider

            {
                logger.info("Classe "+authentication.getClass().getName()+" non supportata");
            }
            return null;
        }
        if( authentication instanceof WebSealIvUserNameAuthenticationToken )
        {
            return doAuthenticationNow(authentication);
        }
        return null;
    }

    @Override

    {
        return WebSealIvUserNameAuthenticationToken.class.isAssignableFrom(authentication);

        try {

        } catch (final Exception e) {
            throw new BadCredentialsException(e.getMessage(), e);
        }
    }

    protected UserDetails loadUserByIvUserName( final String ivUserName )
    {
        return this.authenticationUserDetailsService.loadUserDetails(new WebSealIvUserNameAuthenticationToken(ivUserName));
    }
}

我的身份验证令牌

        }

        if (obj instanceof WebSealAuthenticationToken) {
            WebSealAuthenticationToken test = (WebSealAuthenticationToken) obj;

            if (!this.ivUserName.equals(test.getIvUserName())) {
                return false;
            }
            return true;
        }

        return false;
    }
}

My AuthenticationUserDetailsService

public abstract class AbstractUserDetailsService implements AuthenticationUserDetailsService<WebSealIvUserNameAuthenticationToken>
{

    @Override
    public UserDetails loadUserDetails(final WebSealIvUserNameAuthenticationToken token) throws UsernameNotFoundException
    {
        return loadUserDetails(token.getIvUserName());
    }
    protected abstract UserDetails loadUserDetails(String ivUserName);
}

public class GrantedFromIvUsernameAttributesUserDetailsService extends AbstractUserDetailsService
{
    private static final String NON_EXISTENT_PASSWORD_VALUE = "NO_PASSWORD";
    @Override
    protected UserDetails loadUserDetails(String ivUserName)
    {
        // TODO Inserire il codice per recuperare l'utente da PUMA
        final List<GrantedAuthority> grantedAuthorities = new ArrayList<GrantedAuthority>();
        grantedAuthorities.add(new SimpleGrantedAuthority("OMNIA_ADMIN"));
        grantedAuthorities.add(new SimpleGrantedAuthority("DOMAIN_ADMIN"));
        grantedAuthorities.add(new SimpleGrantedAuthority("OMNIA_GUEST"));
        grantedAuthorities.add(new SimpleGrantedAuthority("DOMAIN_GUEST"));
        return new User("fromWebSeal", NON_EXISTENT_PASSWORD_VALUE, true, true, true, true, grantedAuthorities);
    }

}

我的身份验证DetailsSource

public class ServiceAuthenticationDetailsSource implements AuthenticationDetailsSource<HttpServletRequest, ServiceAuthenticationDetails>
{

    @Override
    public ServiceAuthenticationDetails buildDetails(HttpServletRequest request)
    {
        return new DefaultServiceAuthenticationDetails(request);
    }

}

public class DefaultServiceAuthenticationDetails extends WebAuthenticationDetails implements ServiceAuthenticationDetails
{
    private static final long serialVersionUID = 6056034551086630421L;
    private String ivUserName;
    public DefaultServiceAuthenticationDetails(HttpServletRequest request)
    {
        super(request);
        String headerParam = request.getHeader(WebSealRequestMatcher.DEFAULT_HEADER_PARAM);
        this.ivUserName = StringUtils.hasText(headerParam) ? headerParam : "nonValorizzato"+System.nanoTime();
    }
    @Override
    public String getIvUserName()
    {
        return ivUserName;
    }
    @Override
    public int hashCode() {
        final int prime = 31;
        int result = super.hashCode();
        result = prime * result + ivUserName.hashCode();
        return result;
    }
    @Override
    public boolean equals(Object obj) {
        if (this == obj) {
            return true;
        }
        if (!super.equals(obj) || !(obj instanceof DefaultServiceAuthenticationDetails)) {
            return false;
        }
        ServiceAuthenticationDetails that = (ServiceAuthenticationDetails) obj;
        return ivUserName.equals(that.getIvUserName());
    }
}
public interface ServiceAuthenticationDetails extends Serializable
{

    public String getIvUserName();
}

在我看来，这一切都是正确的；无论如何，当我试图访问页面http://myhost:myport/media/comiajax/pages/uploadmedia时，我遇到了一个循环，页面无法加载....有人能帮我吗？

欢迎提供任何提示

谢谢。

Answer 1

我刚刚意识到我在代码中犯了一些错误：）并不是所有的代码都能很好地工作；首先，我以这种方式修改了入口点：

public class WebSealEntryPoint implements AuthenticationEntryPoint, InitializingBean
{
    private String webSealUrl;
    @Override
    public void afterPropertiesSet() throws Exception
    {
        Assert.hasLength(this.webSealUrl, "Indicare l'URL del WebSeal");
    }

    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authExp) throws IOException, ServletException
    {

        String url = webSealUrl+"?service="+request.getRequestURL();
        response.sendRedirect(url);
    }

    public String getWebSealUrl()
    {
        return webSealUrl;
    }

    public void setWebSealUrl(String webSealUrl)
    {
        this.webSealUrl = webSealUrl;
    }
}

正如yuo所看到的，我添加了一个与CAS添加的重定向非常相似的重定向；然后我以这种方式修改了security-context.xml：
