Liferay Portlet的动态URL

我正在寻找一种解决方案，用于开发具有不同URL的动态内容Liferay Portlet。我不会在Liferay中创建单独的页面。所有信息都存储在单独的数据库中，所有页面都是使用Liferay Portlet生成的。我当前的Liferay版本是6.2 CE

示例URL是

https://localhost/travel/hotel/Lanzarote/Costa Teguise/Hotel Beatriz Costa & Spa
https://localhost/travel/hotel/Lanzarote/Costa Teguise/Club Siroco Apartments
https://localhost/travel/hotel/Lanzarote/Costa Teguise/El Guarapo Apartments

如何在Liferay中实现不同的URL而不创建单独的页面？如果我需要使用Liferay API生成动态url，我需要使用哪些API组件？

您可以通过Liferay友好的url映射获得非常相似的url：

https://localhost:8080/{page}/-/hotel/Lanzarote/Costa Teguise/Hotel Beatriz Costa
https://localhost:8080/{page}/-/hotel/Lanzarote/Costa Teguise/Club Siroco Apartments
https://localhost:8080/{page}/-/hotel/Lanzarote/Costa Teguise/El Guarapo Apartments

要使其正常工作，您需要在

liferayportlet.xml

中配置映射：

<portlet>
    <portlet-name>my-hotel-portlet</portlet-name>
    <friendly-url-mapper-class>com.liferay.portal.kernel.portlet.DefaultFriendlyURLMapper</friendly-url-mapper-class>
    <friendly-url-mapping>hotel</friendly-url-mapping>
    <friendly-url-routes>friendly-url-routes.xml</friendly-url-routes>
    ...
</portlet>

示例Liferay MVCPortlet方法读取参数：

@Override
public void doView(RenderRequest renderRequest, RenderResponse renderResponse) {
    String region = ParamUtil.getString(renderRequest, "region");
    String town = ParamUtil.getString(renderRequest, "town");
    String hotel = ParamUtil.getString(renderRequest, "hotel");
    ...
}

@RenderMapping
public String renderHotel(@RequestParam String region, @RequestParam String town, @RequestParam String hotel) {
    ...
    return "hotel/view";
}

读取参数的弹簧控制器方法示例：

@Override
public void doView(RenderRequest renderRequest, RenderResponse renderResponse) {
    String region = ParamUtil.getString(renderRequest, "region");
    String town = ParamUtil.getString(renderRequest, "town");
    String hotel = ParamUtil.getString(renderRequest, "hotel");
    ...
}

@RenderMapping
public String renderHotel(@RequestParam String region, @RequestParam String town, @RequestParam String hotel) {
    ...
    return "hotel/view";
}

另一个解决方案是编写一个单独的servlet过滤器挂钩插件项目。其想法是将当前URL转换为特定于Liferay的URL

例如：

https://localhost/travel/hotel/Lanzarote/Costa Teguise/Hotel Beatriz Costa & Spa

转化为

https://localhost/web/guest/travel/hotel?p_p_id=hotelsearch_WAR_hotelportlet&p_p_lifecycle=1&p_p_state=normal&p_p_mode=view&_hotelsearch_WAR_hotelportlet_param1=travel&_hotelsearch_WAR_hotelportlet_param2=hotel&_hotelsearch_WAR_hotelportlet_param3=Lanzarote&_hotelsearch_WAR_hotelportlet_param4=Costa%20Teguise&_hotelsearch_WAR_hotelportlet_param5=Hotel%20Beatriz%20Costa%20&%20Spa

首先在示例钩子项目liferay-hook.xml中配置映射：

<?xml version="1.0"?>
<!DOCTYPE hook PUBLIC "-//Liferay//DTD Hook 6.2.0//EN" 
"http://www.liferay.com/dtd/liferay-hook_6_2_0.dtd">
<hook>
<servlet-filter>
    <servlet-filter-name>CustomURLPatternFilter</servlet-filter-name>
    <servlet-filter-impl>com.hotel.travel.portlet.customefilter.CustomURLPatternFilter</servlet-filter-impl>
    <init-param>
        <param-name>hello</param-name>
        <param-value>world</param-value>
    </init-param>
</servlet-filter>
<servlet-filter-mapping>
    <servlet-filter-name>CustomURLPatternFilter</servlet-filter-name>
    <url-pattern>/travel/hotel/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
</servlet-filter-mapping>

在最初的hotel portlet的末尾

    HttpServletRequest httpReq = PortalUtil.getOriginalServletRequest(PortalUtil.getHttpServletRequest(req));
    System.out.println( httpReq.getParameter("_hotelsearch_WAR_hotelportlet_param1") );
    System.out.println( httpReq.getParameter("_hotelsearch_WAR_hotelportlet_param2") );
    System.out.println( httpReq.getParameter("_hotelsearch_WAR_hotelportlet_param3") );
    System.out.println( httpReq.getParameter("_hotelsearch_WAR_hotelportlet_param4") );
    System.out.println( httpReq.getParameter("_hotelsearch_WAR_hotelportlet_param5") );

您应该检查这里也讨论了-。如果这个URL模式是由第三方定义的呢？那么我就不能使用liferay友好的url映射概念。如果你有一个严格的url格式，你必须遵守，你可以使用url重写（正如你自己在另一个答案中建议的那样）。如果你采用url重写的方式，你不必编写自己的过滤器。Liferay利用tuckey的URLRewiteFilter（），它支持转发。添加新规则意味着修改

/ROOT/WEB-INF/urlrewrite.xml

（手动或使用ext插件）。
