我想要做的是，传递clientId给ClearSession()并使用clientIdinrun()来调用session.loadByLastAccessed()。但它抛出的错误是......
Service.java:117: non-static variable this cannot be referenced from a static context
at Thread t = new Thread(new ClearSession(clientId)) (since it is inner class)
如果我将类更改为is static，它将在session.loadByLastAccessed(entityManager, clientId);since entityManageris上引发错误non-static。
关于如何start()从方法中创建线程static并传递non-static变量的任何想法？
这是我的代码...
private EntityManager entityManager; //declared within class along with code below.
public static void initClients()
throws SessionServiceException
{
Properties properties = ApplicationConfig.getInstance().getProperties();
Set<Object> keys = properties.keySet();
String clientId = null;
for (Object keyObject : keys)
{
String key = (String)keyObject;
if (key.startsWith(SessionFactory.CLIENT_PREFIX))
{
clientId = StringUtils.substringAfter(key, SessionFactory.CLIENT_PREFIX);
SessionFactory.getSessionIntf(clientId);
}
}
if(!StringUtils.equals("branch", clientId ))
{
Thread t = new Thread(new ClearSession(clientId));
t.start();
}
}
private class ClearSession implements Runnable
{
private String clientId = "";
public ClearSession(String clientId)
{
this.clientId = clientId;
}
public void run()
{
try
{
// Pause for 2 hours
Thread.sleep(7200000);
// get client session
AbstractImpl session = SessionFactory.getSessionIntf(clientId);
session.loadByLastAccessed(entityManager, clientId);
} catch (InterruptedException ie) {
throw ie;
}
}
}
