现在在做一个web项目，使用spring+springMVC+hibernate框架，
问题描述：
项目中有一个扫描的功能，分即时任务、定时任务、周期任务三种，即时任务已经实现了，现在使用java.util.Timer、java.util.TimerTask类做定时任务，重写TimerTask的run方法，在run方法中调用之前已经没有问题的即时任务扫描方法。每次运行定时任务时，会卡在dao层方法的调用上，因为在即时任务的扫描方法中调用了dao层的数据操作方法，报错“No Session found for current thread”。
即时任务的执行流程：前台提交即时任务扫描请求->控制器调用service层的立即扫描方法startImmediateTask()；
定时任务的执行流程：前台提交定时任务扫描请求->控制器调用service层的定时扫描方法startTimerTask()->调用立即扫描方法startImmediateTask()。
下面附上代码和配置文件，请各位大牛帮忙解决啊！
service层代码
/**
* 开始定时扫描任务
* @param blTask
*/
public void startTimerTask(final BLTask blTask) {
Date startDate = blTask.getStartTime();
TimerTask task = new TimerTask() {
@Override
public void run() {
// 调用扫描方法
startImmediateTask(blTask);
}
};
Timer timer = new Timer();
timer.schedule(task, startDate);
}
/**
* 开始即时扫描任务
* @param blTask
*/
public void startImmediateTask(BLTask blTask) {
BLScanParam blScanParam = new BLScanParam();
BLPolicyGroup blPolicyGroup = null; // 策略组
List<BLCheckItem> blCheckItems = null; // 检查项
Map<Long, BLCheckScript> blCheckScriptMap = new HashMap<Long, BLCheckScript>(); // 检查脚本
Long pgId = null; // 策略组ID
String alias = null; // 策略别名、检查项别名
Long osType = blTask.getOsType(); // 操作系统类型
List<Long> csIds = new ArrayList<Long>(); // 检查脚本ID数组
blScanParam.setBlTask(blTask);
pgId = blTask.getPgId();
// 通过策略组ID查找策略组
blPolicyGroup = blPolicyGroupDao.get(pgId);
if (blPolicyGroup == null) {
return;
}
blScanParam.setBlPolicyGroup(blPolicyGroup);
alias = blPolicyGroup.getAlias();
// 通过别名、操作系统类别查找所有匹配的检查项
blCheckItems = blCheckItemDao.queryByProerties(new String[]{"alias", "osType"}, new Object[]{alias, osType});
if (blCheckItems == null || blCheckItems.size() <= 0) {
return;
}
blScanParam.setBlCheckItems(blCheckItems);
for (BLCheckItem blCheckItem : blCheckItems) {
csIds.add(blCheckItem.getCsId());
}
int size = csIds.size();
// 获取当前策略组下的所有检查项的检测脚本
List<BLCheckScript> blCheckScripts = blCheckScriptDao.queryByProerties("csId", (Long[])csIds.toArray(new Long[size]));
for (BLCheckScript blCheckScript : blCheckScripts) {
// 获取当前策略组下的所有检测脚本，并放入map中
blCheckScriptMap.put(blCheckScript.getCsId(), blCheckScript);
}
blScanParam.setBlCheckScriptMap(blCheckScriptMap);
// 分割ip为数组，传入TaskDispatch
String[] ips = getIps(blTask.getIpArea());
TaskDispatch taskDispatch = new TaskDispatch(ips, blScanParam);
taskDispatch.StartTask();
// 将当前TaskDispatch对象的引用放入taskDispatchMap中，供停止任务时使用
taskDispatchMap.put(blTask.getTkId(), taskDispatch);
}
BaseDao的部分代码
public class BaseDao<E> implements Dao<E> {
public SessionFactory getSessionFactory() {
return this.sessionFactory;
}
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public Session getSession() {
return this.sessionFactory.getCurrentSession();
}
@Resource(name = "sessionFactory")
public void setSF(SessionFactory sessionFactory) {
setSessionFactory(sessionFactory);
}
}
