在liferay中登录后声明的事件

我使用liferay 5.2和tomcat 6

我想在用户连接到我的应用程序时保存idportal和日期登录

在liferay被宣誓作证

我应该找到负责登录的事件

我确实使用了一个代码，该代码将在此事件后进行更新：onAfterCreate

import com.liferay.portal.model.User;
.........
........
 public void onAfterCreate(User user)
    throws ModelListenerException
  {
    System.out.println("-------------- User Creation::" + user.getScreenName());
    try
    {
      Employee employee = getEmployee(user.getScreenName());

      if (employee != null)
        updateEmployee(employee, user, false);
      else
        updateEmployee(new Employee(), user, true);
    }
    catch (Exception e) {
      e.printStackTrace();
    }
  }

所以我应该使用与前面代码相同的代码

idportal是：user.getScreenName（）

我认为登录日期是user.getLastLoginDate（）

但我没有找到登录后将贴花的事件

已更新：

我跟随你的脚步

在liferay-hook.xml中，我添加了以下代码：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hook PUBLIC "-//Liferay//DTD Hook 6.1.0//EN" "http://www.liferay.com/dtd/liferay-hook_6_1_0.dtd">

<hook>
    <portal-properties>portal.properties</portal-properties>
</hook>

package com.liferay.hooks.user;


import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.liferay.portal.kernel.events.Action;
import com.liferay.portal.kernel.events.ActionException;
import com.liferay.portal.kernel.util.WebKeys;
import com.liferay.portal.model.User;
import com.liferay.portal.theme.ThemeDisplay;




public class LoginPostAction extends Action 

{

    public void run(HttpServletRequest request, HttpServletResponse response)
            throws ActionException {

        System.out.println("  the user is connected ");
        ThemeDisplay themeDisplay = (ThemeDisplay)request.getAttribute(WebKeys.THEME_DISPLAY);
        User user = themeDisplay.getUser();
        System.out.println("user "+user.getScreenName());

    }



}

login.events.post=com.liferay.hooks.user.LoginPostAction
servlet.service.events.post=com.liferay.hooks.user.LoginPostAction

我创建了一个java类：loginpostation.java

package com.liferay.hooks.user;


import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.liferay.portal.kernel.events.Action;
import com.liferay.portal.kernel.events.ActionException;



public class LoginPostAction  

{

    public void run(HttpServletRequest request, HttpServletResponse response)
            throws ActionException {

        System.out.println("  the user is connected ");
    }



}

在本例中，导入com.liferay.portal.kernel.events.Action；未使用

正如您所看到的，我希望使用此代码在登录后显示消息

但在部署此示例时，出现了以下错误：

Caused by: java.lang.ClassCastException: com.liferay.hooks.user.LoginPostAction cannot be cast to com.liferay.portal.kernel.events.Action
    at com.liferay.portal.deploy.hot.HookHotDeployListener.initEvent(HookHotDeployListener.java:591)

    at com.liferay.portal.events.EventsProcessorImpl.processEvent(EventsProcessorImpl.java:92)

更新：

我想显示已连接用户的屏幕名和登录日期

我已经使用此代码来显示ScreenName

user.getScreenName（）

，对于登录日期，我认为应该使用

user.getLastLoginDate（

）并使用此导入

import com.liferay.portal.model.User;

但是我没有找到在run函数中使用此代码的方法

package com.liferay.hooks.user;


import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.liferay.portal.kernel.events.Action;
import com.liferay.portal.kernel.events.ActionException;



public class LoginPostAction extends Action

{

    public void run(HttpServletRequest request, HttpServletResponse response)
            throws ActionException {

        System.out.println("  the user is connected ");

     // here I want to display the ScreenName and login date of user connected
    }



}

我尝试使用以下代码：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hook PUBLIC "-//Liferay//DTD Hook 6.1.0//EN" "http://www.liferay.com/dtd/liferay-hook_6_1_0.dtd">

<hook>
    <portal-properties>portal.properties</portal-properties>
</hook>

package com.liferay.hooks.user;


import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.liferay.portal.kernel.events.Action;
import com.liferay.portal.kernel.events.ActionException;
import com.liferay.portal.kernel.util.WebKeys;
import com.liferay.portal.model.User;
import com.liferay.portal.theme.ThemeDisplay;




public class LoginPostAction extends Action 

{

    public void run(HttpServletRequest request, HttpServletResponse response)
            throws ActionException {

        System.out.println("  the user is connected ");
        ThemeDisplay themeDisplay = (ThemeDisplay)request.getAttribute(WebKeys.THEME_DISPLAY);
        User user = themeDisplay.getUser();
        System.out.println("user "+user.getScreenName());

    }



}

login.events.post=com.liferay.hooks.user.LoginPostAction
servlet.service.events.post=com.liferay.hooks.user.LoginPostAction

我在portal.properties中生成以下代码：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hook PUBLIC "-//Liferay//DTD Hook 6.1.0//EN" "http://www.liferay.com/dtd/liferay-hook_6_1_0.dtd">

import com.liferay.portal.kernel.events.Action;
import com.liferay.portal.kernel.events.ActionException;
import com.liferay.portal.kernel.util.WebKeys;
import com.liferay.portal.model.User;
import com.liferay.portal.theme.ThemeDisplay;




public class LoginPostAction extends Action 

{

    public void run(HttpServletRequest request, HttpServletResponse response)
            throws ActionException {

        System.out.println("  the user is connected ");
        ThemeDisplay themeDisplay = (ThemeDisplay)request.getAttribute(WebKeys.THEME_DISPLAY);
        User user = themeDisplay.getUser();
        System.out.println("user "+user.getScreenName());

    }



}

login.events.post=com.liferay.hooks.user.LoginPostAction
servlet.service.events.post=com.liferay.hooks.user.LoginPostAction

但我有一个错误：

Caused by: java.lang.ClassCastException: com.liferay.hooks.user.LoginPostAction cannot be cast to com.liferay.portal.kernel.events.Action
    at com.liferay.portal.deploy.hot.HookHotDeployListener.initEvent(HookHotDeployListener.java:591)

您正在使用的侦听器是“模型侦听器”，它们用于添加\更新\删除事件

侦听登录事件。您可以执行以下操作：

在

liferayhook.xml

文件中，向

hook

元素添加

portal属性。比如说,

<hook>
    <portal-properties>portal.properties</portal-properties>
</hook>

然后扩展

com.liferay.portal.kernel.events.Action

实施：

public void run(HttpServletRequest request, HttpServletResponse response)
    throws ActionException;

谢谢你的回复，我已经更新了我的question@franco您在更新的问题中遗漏了第4步-错误消息清楚地表明非常感谢您，现在我想显示已连接用户的屏幕名和登录日期，我更新了我的问题我在使用以前的代码删除时出现错误NullPointerException:

servlet.service.events.post=com.liferay.hooks.user.loginpostation

。它将在Struts每次处理可能有或可能没有登录用户的请求时运行。
