重写了UsernamePasswordAuthenticationFilter,里面继承AbstractAuthenticationProcessingFilter,这个类里面的session认证策略,是一个空方法,貌似RememberMe也是.
public abstract class AbstractAuthenticationProcessingFilter extends GenericFilterBean implements ApplicationEventPublisherAware, MessageSourceAware { protected ApplicationEventPublisher eventPublisher; protected AuthenticationDetailsSource<HttpServletRequest, ?> authenticationDetailsSource = new WebAuthenticationDetailsSource(); private AuthenticationManager authenticationManager; protected MessageSourceAccessor messages = SpringSecurityMessageSource.getAccessor(); private RememberMeServices rememberMeServices = new NullRememberMeServices(); private RequestMatcher requiresAuthenticationRequestMatcher; private boolean continueChainBeforeSuccessfulAuthentication = false; private SessionAuthenticationStrategy sessionStrategy = new NullAuthenticatedSessionStrategy(); private boolean allowSessionCreation = true; private AuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler(); private AuthenticationFailureHandler failureHandler = new SimpleUrlAuthenticationFailureHandler();
NullAuthenticatedSessionStrategy 源码
public final class NullAuthenticatedSessionStrategy implements SessionAuthenticationStrategy { public NullAuthenticatedSessionStrategy() { } public void onAuthentication(Authentication authentication, HttpServletRequest request, HttpServletResponse response) { } }
所以必须自己配置一个session验证策略,以及配置并发控制.红字为关键

继承UsernamePasswordAuthenticationFilter ,注入SessionRegistry ,当用户登录验证成功后注册session
/** * Created by ZhenWeiLai on 2017/6/2. */ public class CuzUsernamePasswordAuthenticationFilter extends UsernamePasswordAuthenticationFilter { private boolean postOnly = true; @Resource private SessionRegistry sessionRegistry; @Override public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException { if(this.postOnly && !request.getMethod().equals("POST")) { throw new AuthenticationServiceException("Authentication method not supported: " + request.getMethod()); } else { String username = this.obtainUsername(request); String password = this.obtainPassword(request); if(username == null) { username = ""; } if(password == null) { password = ""; } username = username.trim(); UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(username, password); //用户名密码验证通过后,注册session sessionRegistry.registerNewSession(request.getSession().getId(),authRequest.getPrincipal()); this.setDetails(request, authRequest); return this.getAuthenticationManager().authenticate(authRequest); } } }
重写用户实体类的比较方法.
/** * 重写比较方法,SpringSecurity根据用户名来比较是否同一个用户 */ @Override public boolean equals(Object o){ if(o.toString().equals(this.username)) return true; return false; } @Override public int hashCode(){ return username.hashCode(); } @Override public String toString() { return this.username; }
