我使用Spring安全性,当我使用相同的用户(我设置为可能有多个会话)从不同的浏览器登录时,从控制器传递的数据(我从中获取SessionInformation)对于视图正在被复制而不是创建新的会话ID,并且最后一个活动对于所有不同的浏览器会话也是如此。
这是spring-security.xml的一部分,其中配置了sessionRegistry和stuff。
<form-login login-page="/login" default-target-url="/welcome" always-use-default-target="true"
authentication-failure-url="/loginfailed"/>
<logout logout-success-url="/logout" />
<custom-filter position="CONCURRENT_SESSION_FILTER" ref="concurrencyFilter" />
<custom-filter after="FORM_LOGIN_FILTER" ref="myAuthFilter" />
<session-management session-authentication-strategy-ref="sas"/>
</http>
<authentication-manager alias="authenticationManager">
<authentication-provider ref="ldapAuthProvider">
</authentication-provider>
</authentication-manager>
<beans:bean id="concurrencyFilter"
class="org.springframework.security.web.session.ConcurrentSessionFilter">
<beans:property name="sessionRegistry" ref="sessionRegistry" />
</beans:bean>
<beans:bean id="myAuthFilter" class=
"org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter">
<beans:property name="sessionAuthenticationStrategy" ref="sas" />
<beans:property name="authenticationManager" ref="authenticationManager" />
</beans:bean>
<beans:bean id="sas" class=
"org.springframework.security.web.authentication.session.ConcurrentSessionControlStrategy">
<beans:constructor-arg name="sessionRegistry" ref="sessionRegistry" />
<beans:property name="maximumSessions" value="-1" />
</beans:bean>
<beans:bean id="sessionRegistry"
class="org.springframework.security.core.session.SessionRegistryImpl" />
这是使用sessionRegistry的Controller:
@RequestMapping(value = "/activeusers", method = RequestMethod.GET)
public String manageActiveUsers(ModelMap model, Principal principal) {
String name = principal.getName();
model.addAttribute("username", name);
List<LoginUserInfo> userSessionData = new ArrayList<LoginUserInfo>();
List<Object> principals = sessionRegistry.getAllPrincipals();
//TODO: Find a better way to get the remote IP Address according to each client call
String remoteAddress = ((ServletRequestAttributes)RequestContextHolder.currentRequestAttributes())
.getRequest().getLocalAddr();
for (Object object : principals) {
LoginUserInfo userInfo = new LoginUserInfo();
LdapUserDetailsImpl user = (LdapUserDetailsImpl) object;
List<SessionInformation> sessions = sessionRegistry.getAllSessions(user, false);
String username = user.getUsername();
for (SessionInformation session : sessions) {
Date lastRequest = session.getLastRequest();
String sessionId = session.getSessionId();
userInfo.setUsername(username);
userInfo.setIp(remoteAddress);
userInfo.setLastActivity(lastRequest.getTime());
userInfo.setSessionId(sessionId);
userSessionData.add(userInfo);
}
}
model.addAttribute("userSessionData", userSessionData);
return "activeusers";
}
然后我发送&#34; userSessionData&#34;像这样的jsp VIEW。
<c:forEach var="userDetail" items="${userSessionData}">
<tr>
<td><c:out value="${userDetail.ip}"/></td>
<td><c:out value="${userDetail.username}"/></td>
<td><c:out value="${userDetail.lastActivity}"/></td>
<td><c:out value="${userDetail.sessionId}"/></td>
</tr>
</c:forEach>
正如我所说,即使我从另一个浏览器登录,所有与用户相关的数据都被复制(sessionId和lastActivity)。当我从一个浏览器做一些请求时,lastActivity会同时在所有会话中刷新。
另一件事,当我从不同的浏览器注销时,会话终止。但是当我检查会话列表时,仍然存在。为什么会这样呢???

这不是您的会话的问题,这是您的for
循环的问题。
每个用户只能创建一个LoginUserInfos
,并且会为每个会话重复使用此对象。因此,您只能看到上次会话的数据。而是在内部循环中创建LoginUserInfos
。
for (Object object : principals) {
LdapUserDetailsImpl user = (LdapUserDetailsImpl) object;
List<SessionInformation> sessions = sessionRegistry.getAllSessions(user, false);
String username = user.getUsername();
for (SessionInformation session : sessions) {
LoginUserInfo userInfo = new LoginUserInfo();
Date lastRequest = session.getLastRequest();
String sessionId = session.getSessionId();
userInfo.setUsername(username);
userInfo.setIp(remoteAddress);
userInfo.setLastActivity(lastRequest.getTime());
userInfo.setSessionId(sessionId);
userSessionData.add(userInfo);
}
}
这应该会给你预期的结果。
