我在长期运行的应用程序中使用Apache Shiro 1.2.0,该应用程序从队列中读取消息并采取措施。所采取的操作需要一个Shiro身份验证会话,因此我实现了一个“ActAsAuthenticationToken”和自定义凭据匹配器,它允许我们只使用用户名登录。我正在使用DefaultSecurityManager,只有我的自定义领域和主题工厂注入。其他一切都应该是默认的。
在配置的时候,一切都运行良好一段时间,但是由于应用程序运行了很长时间(不是那么长 - 就像一整天),每当我做任何需要会话的事情时,我就开始得到这个堆栈跟踪: / p>

真正奇怪的部分(据我所知)是我成功登录(或至少表明我在收到错误之前已经过身份验证:
@Transactional(propagation = Propagation.REQUIRED, isolation = Isolation.REPEATABLE_READ)
@Trace(dispatcher = true)
public void receiveOpportunityEvent(EntityEvent<Opportunity> event) {
sessionFactory.getCurrentSession().refresh(event.getEntity());
log.info("OpportunityScoreUpdateService receiveOpportunityEvent: " + event);
//
//
// Here we see that we are either authenticated or we log in successfully
//
//
if (!securityUtils.getSubject().isAuthenticated()) {
try {
securityUtils.getFactorlabSubject().login(new ActAsAuthenticationToken(event.getEventUsername()));
} catch (RuntimeException e) {
log.error("Could not log in user " + event.getEventUsername() + ": " + e.getMessage(), e);
return;
}
}
if (event.getEntity() instanceof ObservedOpportunity) {
ObservedOpportunity opportunity = (ObservedOpportunity) event.getEntity();
opportunity = (ObservedOpportunity) opportunityDao.getById(opportunity.getId(), SkippedCheck.PERMISSION, SkippedCheck.DELETED);
if (!opportunity.isDeleted()) {
List<Stage> stages = stageDao.getAllByZone(opportunity.getZone(), SkippedCheck.PERMISSION);
Map<Stage, Double> originalScoresByStage = new HashMap<Stage, Double>();
Map<Stage, Double> newScoresByStage = new HashMap<Stage, Double>();
final Double originalTotal = opportunity.getTotalScore();
for (Stage stage : stages) {
originalScoresByStage.put(stage, opportunity.getScoreByStage(stage));
double score = calculator.getScoreForOpportunityAndStage(opportunity, stage);
opportunity.setScoreByStage(stage, score);
newScoresByStage.put(stage, opportunity.getScoreByStage(stage));
}
final double newTotalScore = calculator.getTotalScoreForOpportunity(opportunity);
opportunity.setTheTotalScore(newTotalScore);
final boolean scoreChanged = originalTotal == null ||
Math.round(originalTotal) != Math.round(newTotalScore) ||
checkStageScoresChanged(originalScoresByStage, newScoresByStage);
if (scoreChanged) {
opportunity.setScoreCalculated(new Date());
//
//
// Here is where we get the exception
//
//
opportunityDao.saveOrUpdate(opportunity, SkippedCheck.PERMISSION);

opportunityDao.refresh(opportunity);
}
}
}
}
可能导致此异常的原因是什么?

我收到此错误并发现在调用subject.login(credentials)
修复它之前完全破坏了任何现有会话。
// Login the user
private Subject loginUser()
{
ensureUserIsLoggedOut();
Subject subject = SecurityUtils.getSubject();
subject.login(credentials);
}
支持程序是:
// Logout the user fully before continuing.
private void ensureUserIsLoggedOut()
{
try
{
// Get the user if one is logged in.
Subject currentUser = SecurityUtils.getSubject();
if (currentUser == null)
return;
// Log the user out and kill their session if possible.
currentUser.logout();
Session session = currentUser.getSession(false);
if (session == null)
return;
session.stop();
}
catch (Exception e)
{
// Ignore all errors, as we're trying to silently
// log the user out.
}
}

Shiro正在验证SecuritySubject的凭据,SecuritySubject存储在Session中。因此,在一段时间不活动后,您的会话很可能会过期。您可以在web.xml中更改到期时间,也可以使用Shiro rememberMe功能,但您的客户端必须支持cookie。在rememberMe函数之后,SecuritySubject将获得不同的会话,并将针对isAuthenticated返回false,但isRemembered将返回true。
会话永不过期当您的会话永不过期时,这会产生另一个问题。它很可能会让你内存不足,因为你的Web容器最有可能使用内存会话管理器。
<session-config>
<session-timeout>-1</session-timeout>
</session-config>
Shiro rememberMe http://shiro.apache.org/java-authentication-guide.html
//Example using most common scenario:
//String username and password. Acquire in
//system-specific manner (HTTP request, GUI, etc)
UsernamePasswordToken token =
new UsernamePasswordToken( username, password );
//”Remember Me” built-in, just do this:
token.setRememberMe(true);

我们可以在shiro中禁用会话存储。
org.apache.shiro.mgt.DefaultSessionStorageEvaluator类包含一个名为sessionStorageEnabled的标志。我们可以把它弄错。
我在spring应用程序上下文中使用以下内容来不使用会话存储。
<bean id="defaultSessionStorageEvaluator" class="org.apache.shiro.mgt.DefaultSessionStorageEvaluator">
<property name="sessionStorageEnabled" value="false" />
<bean id="defaultSubjectDAO" class="org.apache.shiro.mgt.DefaultSubjectDAO">
<property name="sessionStorageEvaluator" ref="defaultSessionStorageEvaluator" />
</bean>
