我们使用 spring security 根据来自外部应用程序的一些用户详细信息(如 userid )对用户进行身份验证,并使用安全上下文持有者执行授权。我们正在使用 AbstractAuthenticationProcessingFilter 的自定义实现和 CustomAuthenticationProvider 的自定义实现,并将我们自己的 UserDetailsS​​erviceImpl 注入提供程序以从数据库中获取用户详细信息。

当单个用户尝试登录时,它可以正常工作,创建身份验证对象并将其正确设置为 SecurityCONtextHolder。但是当另一个用户尝试登录时,旧的身份验证对象会被新的身份验证对象覆盖。看起来没有在每个用户登录时创建新会话。

过滤器和提供者的实现如下 -

    public class DefaultAuthenticationProcessingFilter extends
    AbstractAuthenticationProcessingFilter {

private final static Logger logger = LoggerFactory.getLogger(DefaultAuthenticationProcessingFilter.class);

private static final String INTERCEPTOR_PROCESS_URL = "/sso/landingpage.action";

public DefaultAuthenticationProcessingFilter() {
    super(INTERCEPTOR_PROCESS_URL);
}

public DefaultAuthenticationProcessingFilter(
        String defaultFilterProcessesUrl) {
    super(defaultFilterProcessesUrl);
    Assert.notNull(defaultFilterProcessesUrl, "Configuration error :: DefaultFilterProcessesUrl must be specified");
}


/**
 * Method to do authentication of user
 */
@Override
public Authentication attemptAuthentication(HttpServletRequest request,
        HttpServletResponse response) throws AuthenticationException,
        IOException, ServletException {

    logger.info("Authenticating the user .....");

    Authentication authResult = null;
    try {

        String eid = request.getParameter("EID");

        if( StringUtils.isEmpty(eid)) {
             throw new PreAuthenticatedCredentialsNotFoundException("EID param not found in request.");
        }

        String credentials = "NA";
        PreAuthenticatedAuthenticationToken authRequest = new PreAuthenticatedAuthenticationToken(eid, credentials);
        authRequest.setDetails(authenticationDetailsSource.buildDetails(request));
        authResult = getAuthenticationManager().authenticate(authRequest);
    } catch (AuthenticationException e) {
        unsuccessfulAuthentication(request, response, e);
    } 
    return authResult;
}
    }


    protected void successfulAuthentication(HttpServletRequest request, HttpServletResponse response,
            Authentication authResult) throws IOException, ServletException {

        if (logger.isDebugEnabled()) {
            logger.debug("Authentication success. Updating SecurityContextHolder to contain: " + authResult);
        }

        SecurityContextHolder.getContext().setAuthentication(authResult);

        getRememberMeServices().loginSuccess(request, response, authResult);

        // Fire event
        if (this.eventPublisher != null) {
            eventPublisher.publishEvent(new InteractiveAuthenticationSuccessEvent(authResult, this.getClass()));
        }

        getSuccessHandler().onAuthenticationSuccess(request, response, authResult);
 }
    }

自定义提供者的实现如下 -

    public class CustomAuthenticationProvider implements AuthenticationProvider, InitializingBean {

private final static Logger logger = LoggerFactory.getLogger(CustomAuthenticationProvider.class);

private AuthenticationUserDetailsService<PreAuthenticatedAuthenticationToken> preAuthenticatedUserDetailsService = null;
/**
* 
*/
public Authentication authenticate(Authentication authentication) throws AuthenticationException {

    if (!supports(authentication.getClass())) {
        return null;
    }

    if (logger.isDebugEnabled()) {
        logger.debug("PreAuthenticated authentication request: " + authentication);
    }

    if (authentication.getPrincipal() == null) {
        logger.debug("No pre-authenticated principal found in request.");
        return null;
    }

    UserDetails ud = preAuthenticatedUserDetailsService.loadUserDetails((PreAuthenticatedAuthenticationToken)authentication);

    PreAuthenticatedAuthenticationToken result =
            new PreAuthenticatedAuthenticationToken(ud, authentication.getCredentials(), ud.getAuthorities());
    result.setDetails(authentication.getDetails());

    return result;

}

@Override
public void afterPropertiesSet() throws Exception {
    // TODO Auto-generated method stub
}

@Override
public boolean supports(Class<?> authentication) {
    return PreAuthenticatedAuthenticationToken.class.isAssignableFrom(authentication);
}

/**
 * @return the preAuthenticatedUserDetailsService
 */
public AuthenticationUserDetailsService<PreAuthenticatedAuthenticationToken> getPreAuthenticatedUserDetailsService() {
    return preAuthenticatedUserDetailsService;
}

/**
 * @param preAuthenticatedUserDetailsService the preAuthenticatedUserDetailsService to set
 */
public void setPreAuthenticatedUserDetailsService(
        AuthenticationUserDetailsService<PreAuthenticatedAuthenticationToken> preAuthenticatedUserDetailsService) {
    this.preAuthenticatedUserDetailsService = preAuthenticatedUserDetailsService;
}
}

我们还配置了自定义身份验证成功处理程序,以在身份验证时将用户重定向到适当的 URL -

    public class CustomAuthenticationSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {

/**
 * redirect user to appropriate home page based on user role
 */
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws ServletException, IOException {

    Set<GrantedAuthority> authorities = ((UserDetails)authentication.getPrincipal()).getAuthorities();
    if(CollectionUtils.isNotEmpty(authorities)){
        GrantedAuthority role = getHighestRole(authorities);
        String targetURL = getTargetURL(role);
        if (targetURL != null) {
            log.debug("Redirecting to target Url: " + targetURL);
            getRedirectStrategy().sendRedirect(request, response, targetURL);
            return;
        }
    }

    super.onAuthenticationSuccess(request, response, authentication);

}
  }

弹簧安全配置文件如下 -

<bean id="failureHandler"

我们还配置了 web.xml

我们正在使用 spring 3.1.3 和 spring security 3.1.3 在每个用户登录时应该创建新的会话并相应地设置安全上下文。但它发生在我的情况下。我检查了调试我的应用程序,发现用户登录时没有创建新会话。可能是我在某个地方想念它。我在任何地方都找不到任何相关的解决方案。

在这方面的任何帮助将不胜感激。

谢谢。

对不起,伙计们,虽然我当时和那个时候本身已经解决了这个问题,但我很长时间没有看这个问题 -

我在元素中使用了 securityContextPersistenceFilter 并配置如下 -

<security:http>
 <security:custom-filter before="SECURITY_CONTEXT_FILTER" ref="securityContextPersistenceFilter"/>

……

<bean id="securityContextPersistenceFilter" class="org.springframework.security.web.context.SecurityContextPersistenceFilter">
    <property name="forceEagerSessionCreation" value="true"></property>
     <property name="securityContextRepository" ref="httpSessionSecurityContextRepository"/>
</bean>

<bean id="httpSessionSecurityContextRepository" class="org.springframework.security.web.context.HttpSessionSecurityContextRepository">
 <property name="allowSessionCreation" value="false" />
</bean>
