Liferay:如何保存到Portlet用户信息? [英] Liferay: how to save to portlet user information?

问题描述

我在欢迎页面上有一个天气portlet，用户可以配置portlet并选择他的城市.是否可以在portlet首选项中存储用户信息，以便每个用户都拥有一个存储的城市?还是在不开发自己的(持久性)服务的情况下存储用户门户信息的标准工作流程是什么?

I have at the welcome page a weather portlet, and user can configure the portlet and select his city. Is it possible to store user information in the portlet preferences, so that every user has his one stored city? Or what is the standard workflow to store user-portlet information without to develop own (persist) service?

thx

推荐答案

默认情况下，portlet首选项位于liferay中，而不是特定于用户的.可以在liferay-portlet.xml中用下一行进行修改:

The portlet-preferences are in liferay per default not user specific. That can be modified in liferay-portlet.xml with next lines:

<liferay-portlet-app>
  <portlet>
    <portlet-name>ThePortletWitchUserSpecificPreferences</portlet-name>
    <icon>/icon.png</icon>
    <preferences-unique-per-layout>false</preferences-unique-per-layout>
    <preferences-owned-by-group>false</preferences-owned-by-group>
  </portlet>
...
</liferay-portlet-app>

<preferences-...和两行的缩写.
