SpringBoot整合SpringSecurity,SESSION 并发管理,同账号只允许登录一次

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

        } 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.

     */
    @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;
    }
