- Java 双重比较
- java - 比较器与 Apache BeanComparator
- Objective-C 完成 block 导致额外的方法调用?
- database - RESTful URI 是否应该公开数据库主键?
我正在关注 this Spring.io 指南中有关 Spring Security 的教程。注销和登录功能工作正常,但是当我在 WebSecurityConfigurerAdapter
中添加以下行时,它无法按预期工作。 (基本上,如果用户已经登录了一台设备,我想阻止他从两台设备登录)
@Configuration
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
protected static class SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
// The configuration as in the tutorial
http
.httpBasic().and()
.authorizeRequests()
.antMatchers("/index.html", "/home.html", "/login.html", "/").permitAll()
.anyRequest().authenticated()
.and()
.csrf()
.csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
// Added this for session management
http.sessionManagement().maximumSessions(1).maxSessionsPreventsLogin(true)
}
}
如果您注销并尝试再次登录,则会返回 401 消息“身份验证失败:最大值” 该校长的 1 个 session 超出了'。然而,注销 URL 在 AngularJs
应用程序中的这一部分被命中
self.logout = function() {
$http.post('logout', {}).finally(function() {
$rootScope.authenticated = false;
$location.path("/");
});
}
为什么在这种情况下没有重置 session 数?
如何才能使其按预期工作?

您需要执行以下操作才能使其正常工作:
根据 https://github.com/spring-projects/spring-security/issues/3078 ,您需要明确提供 session 注册表作为解决此问题的方法。(此步骤是可选的。我猜它已在最新版本中修复。如果该功能不起作用,则可以添加此步骤。)
Spring Security 需要注册一个 HttpSessionListener
。
您的最终代码应如下所示:
@Configuration
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
protected class SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
// @formatter:off
http
.httpBasic();
http
.authorizeRequests()
.antMatchers("/index.html", "/home.html", "/login.html", "/").permitAll()
.anyRequest().authenticated()
.and()
.csrf()
.csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
// @formatter:on
http
.sessionManagement()
.maximumSessions(1)
.maxSessionsPreventsLogin(true)
.sessionRegistry(sessionRegistry());
}
}
// Work around https://jira.spring.io/browse/SEC-2855
@Bean
public SessionRegistry sessionRegistry() {
SessionRegistry sessionRegistry = new SessionRegistryImpl();
return sessionRegistry;
}
// Register HttpSessionEventPublisher
@Bean
public static ServletListenerRegistrationBean httpSessionEventPublisher() {
return new ServletListenerRegistrationBean(new HttpSessionEventPublisher());
}
关于java - Spring Security 注销和最大 session 数,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/41429778/
