我希望在插件( portlet , hook 或主题)后立即运行一些代码Liferay提供。
我无法在liferay-plugin-package.xml
,liferay-portlet.xml
,liferay-hook.xml
或liferay-look-and-feel.xml
中找到类似启动监听器的内容。

还有另一种方式。您可以使用StartupAction。它只是一个事件,它会在插件的每次启动时触发。此方法仅在服务器启动或部署时触发一次。认识到,doRun方法得到一个companyIds的String数组作为参数。 companyId表示门户实例(Liferay内部实例。不是另一个应用程序服务器。)
例如,我有一个portlet,我依赖一些自定义字段存在。所以我有这个整洁的小班:
package de.osc.kaleositeaddon.startup;
import com.liferay.portal.kernel.events.ActionException;
import com.liferay.portal.kernel.events.SimpleAction;
public class StartupAction extends SimpleAction {
@Override
public void run(String[] companyIds) throws ActionException {
setupExpandoAction.run(companyIds);
importMessagesAction.run(companyIds);
}
private SetupExpandoAction setupExpandoAction = new SetupExpandoAction();
private ImportMessagesAction importMessagesAction = new ImportMessagesAction();
}
SetupExpandoAction是:
package de.osc.kaleositeaddon.startup;
import com.liferay.portal.kernel.events.ActionException;
import com.liferay.portal.kernel.events.SimpleAction;
import com.liferay.portal.model.Group;
import com.liferay.portal.model.ResourceConstants;
import com.liferay.portal.model.Role;
import com.liferay.portal.model.RoleConstants;

import com.liferay.portlet.journal.model.JournalArticle;
import de.osc.kaleositeaddon.service.constants.ExpandoConstants;
public class SetupExpandoAction extends SimpleAction {
@Override
public void run(String[] companyIds) throws ActionException {
for (int i = 0; i < companyIds.length; i++) {
long companyId = Long.parseLong(companyIds[i]);
try {
setupExpandoGroup(companyId);
} catch (Exception e) {
e.printStackTrace();
}
}
}
protected void setupExpandoGroup(long companyId) throws Exception {
ExpandoTable table = null;
try {
table = ExpandoTableLocalServiceUtil.addTable(companyId, Group.class.getName(), ExpandoTableConstants.DEFAULT_TABLE_NAME);
} catch (DuplicateTableNameException dtne) {
table = ExpandoTableLocalServiceUtil.getTable(companyId, Group.class.getName(), ExpandoTableConstants.DEFAULT_TABLE_NAME);
}
/*
* Setup StartDate
*/
try {
ExpandoColumn column = ExpandoColumnLocalServiceUtil.addColumn(table.getTableId(),
ExpandoConstants.EXPANDO_COLUMN_NAME_START_DATE, ExpandoColumnConstants.DATE);
column.setDefaultData("");
Role user = RoleLocalServiceUtil.getRole(companyId, RoleConstants.GUEST);
ResourcePermissionLocalServiceUtil.setResourcePermissions(companyId, ExpandoColumn.class.getName(), ResourceConstants.SCOPE_INDIVIDUAL,
String.valueOf(column.getColumnId()), user.getRoleId(), new String[] { ActionKeys.VIEW});
}
catch (DuplicateColumnNameException dcne) {
}
/*
* Setup EndDate
*/
try {
ExpandoColumn column = ExpandoColumnLocalServiceUtil.addColumn(table.getTableId(),
ExpandoConstants.EXPANDO_COLUMN_NAME_END_DATE, ExpandoColumnConstants.DATE);
column.setDefaultData("");
Role user = RoleLocalServiceUtil.getRole(companyId, RoleConstants.GUEST);
ResourcePermissionLocalServiceUtil.setResourcePermissions(companyId, ExpandoColumn.class.getName(), ResourceConstants.SCOPE_INDIVIDUAL,
String.valueOf(column.getColumnId()), user.getRoleId(), new String[] { ActionKeys.VIEW});
}
catch (DuplicateColumnNameException dcne) {
}
try {
ExpandoColumn column = ExpandoColumnLocalServiceUtil.addColumn(table.getTableId(),
ExpandoConstants.EXPANDO_COLUMN_NAME_CREATE_DATE, ExpandoColumnConstants.DATE);
column.setDefaultData("");
Role user = RoleLocalServiceUtil.getRole(companyId, RoleConstants.GUEST);
ResourcePermissionLocalServiceUtil.setResourcePermissions(companyId, ExpandoColumn.class.getName(), ResourceConstants.SCOPE_INDIVIDUAL,
String.valueOf(column.getColumnId()), user.getRoleId(), new String[] { ActionKeys.VIEW});
}
catch (DuplicateColumnNameException dcne) {
}
}
}
在liferay-hook.xml文件中,执行以下操作:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hook PUBLIC "-//Liferay//DTD Hook 6.0.0//EN" "http://www.liferay.com/dtd/liferay-hook_6_0_0.dtd">
<hook>
<portal-properties>portal.properties</portal-properties>
</hook>
在portal.properties中添加以下行:
application.startup.events=de.osc.kaleositeaddon.startup.StartupAction
记得替换类名;)

如果您的插件中有portlet,则可以在Portlet.init(PortletConfig)
中运行代码。
但这并非总是可行,因为
在这种情况下,您还有两个选择:
创建为每个门户网站实例调用的启动操作(请参阅answer of gevatterjan)。如果您需要为每个门户网站实例运行代码,这是最佳解决方案。
或者您使用ServletContextListener
和PortalLifecycle
的组合,该插件在插件可用时启动一次。如果您只想运行一次,这是最好的解决方案,例如创建调度程序或替换liferay-hook.xml
resp未涵盖的Liferay函数。 portal.properties
。
@WebListener
public class MyStartupListener implements ServletContextListener, PortalLifecycle {
@Override
public void contextInitialized(final ServletContextEvent sce) {
// Wait until the portal is ready
PortalLifecycleUtil.register(this, PortalLifecycle.METHOD_INIT);
}
@Override
public void portalInit() {
// Here comes our initialization code
...
}
@Override
public void contextDestroyed(final ServletContextEvent event) {
// Here comes our uninitialization code, if any
...
}
@Override
public void portalDestroy() {
// Ignore
}
}
您可以调用任何Liferay函数,但要小心:
您的主题未连接到任何请求 - 目前没有门户网站实例(Company
),网站(Group
),< em> page (Layout
)或 user 。您可以使用适当的*ServiceLocalUtil
函数找到所有这些函数。对于某些操作,您需要为CompanyThreadLocal
,PricipalThreadLocal
和PermissionThreadLocal
中的线程设置这些值。
