java – 注册新的SessionManager
作者:互联网
我有野生飞行8.1服务器运行.我有自己的SessionManager实现io.undertow.server.session.SessionManager.我想配置系统使用我的会话管理器.
我应该在哪里以及如何为会话管理器配置/添加新设置?
解决方法:
public class StartupBeanExtension implements Extension, ServletExtension {
@Override
public void handleDeployment(DeploymentInfo deployment, ServletContext context) {
boolean sessionPersistenceEnabled = Boolean.parseBoolean(BeanUtils.getBean(PropertyResolver.class).getValue("UAM.SessionPersistenceEnabled"));
if (sessionPersistenceEnabled) {
System.out.println("Overriding default InMemorySessionManager...[" + deployment.getDeploymentName() + ", " + deployment.getDisplayName() + "]");
deployment.setSessionManagerFactory(new UAMSessionManagerFactory());
} else {
System.out.println("InMemorySessionManager IS NOT OVERIDED!");
}
}
}
public class UAMSessionManagerFactory implements SessionManagerFactory {
@Override
public SessionManager createSessionManager(Deployment deployment) {
UAMSessionManager ss = new UAMSessionManager(deployment.getDeploymentInfo().getDeploymentName());
return ss;
}
}
public class UAMSessionManager extends InMemorySessionManager {
public UAMSessionManager(String deploymentName) {
super(deploymentName);
UAMSessionListener uamSessionListener = new UAMSessionListener();
super.registerSessionListener(uamSessionListener);
System.out.println("New session manager created. Listener activated.");
}
// create session
public Session createSession(final HttpServerExchange serverExchange, final SessionConfig config, String sessionID) {
config.setSessionId(serverExchange, sessionID);
Session session = super.createSession(serverExchange, config);
return session;
}
// get session
public Session getSession(final HttpServerExchange serverExchange, final SessionConfig config) {
final String sessionId = config.findSessionId(serverExchange);
Session session = getSession(sessionId);
if (session == null) {
// DO SOMETHING TO CREATE SESSION OR RESTORE IT FROM DB
try {
UAMService uam = getUAMService();
if (uam != null) {
Sessions storedSession = uam.getSession(sessionId);
if (storedSession != null) {
String storedSessionId = storedSession.getSessionId();
// create new session with storedSessionID
session = createSession(serverExchange, config, storedSessionId);
// SET session attributes if needed from storedSession to new one
} else {
// let InMemorySessionManager create new session
return null;
}
}
} catch (Exception ex) {
}
}
return session;
}
}
public class UAMSessionListener implements SessionListener {
@Override
public void sessionCreated(Session session, HttpServerExchange exchange) {
}
@Override
public void sessionDestroyed(Session session, HttpServerExchange exchange, SessionDestroyedReason reason) {
}
@Override
public void attributeAdded(Session session, String name, Object value) {
UAMService uamService = getUAMService();
if (uamService != null) {
Sessions storedSession = uamService.getSession(session.getId());
boolean isNew = false;
if (storedSession == null) {
storedSession = new Sessions();
storedSession.setSessionId(session.getId());
storedSession.setActvityDate(new Date());
isNew = true;
}
// STORE SOME INFO FROM value and update/create it in storage
uamService.updateSession(storedSession, isNew);
}
}
@Override
public void attributeUpdated(Session session, String name, Object newValue, Object oldValue) {
}
@Override
public void attributeRemoved(Session session, String name, Object oldValue) {
}
@Override
public void sessionIdChanged(Session session, String oldSessionId) {
}
}
要使用另一个SessionManager覆盖默认的InMemmorySessionManager,应执行以下步骤:
>开发实现io.undertow.server.session.SessionManager的SessionManager
>开发实现io.undertow.servlet.api.SessionManagerFactory的SessionManagerFactory
>开发实现io.undertow.servlet.ServletExtension的启动扩展,并在handleDeployment(Deployment)方法中使用新的SessionManagerFactory更改sessionManagerFactory.
>通过添加../META-INF/services/io.undertow.servlet.ServletExtension文件来注册新的ServletExtension(文件应包含新ServletExtension的名称.例如com.my.utils.StartupExtension)
