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 UserDetailsServiceImpl 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 -

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。
