我已将最大会话数配置为 1 并设置error-if-maximum-exceeded=true
我注意到两个问题:
1-如果已配置session-authentication-error-url
则不起作用,优先,然后您必须在那里处理并制定所需的逻辑。authentication-failure-handler-ref
authentication-failure-handler-ref
SessionAuthenticationException
2-如果我在 chrome 中打开会话并尝试在 firefox 中登录,SessionAuthenticationException
但如果我尝试在 chrome 中再次登录(已经有一个打开的会话),我会成功登录并且没有得到SessionAuthenticationException
我应该阻止用户如果他已经通过身份验证,从查看登录页面?如果这是正确的,请告知如何做到这一点。
我通常按如下方式检查经过身份验证的用户:
if(!SecurityContextHolder.getContext().getAuthentication().getPrincipal().equals("anonymousUser")){
// logged in user
}
这是我当前的配置:
1- web.xml:
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>
org.springframework.web.filter.DelegatingFilterProxy
</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>
<listener>
<listener-class>
org.springframework.security.web.session.HttpSessionEventPublisher
</listener-class>
</listener>
2- applicationSecurity.xml:
