java - Liferay : Configuring Multiple Spring MVC Portlets in one liferay plugin project with one common controller and multiple landing pages

Question

我正在liferay中开发基于Spring MVC的portlet。基本上我想在单个 liferay 项目本身中配置和维护 2 或 3 个 portlet。有人可以指导我进行相同的配置吗？就像 portlet.xml、spring 配置和 web 配置(如果需要)的配置代码。我只需要为所有 portlet 配置一个默认 Controller ，这样每个 portlet 就会登陆不同的登陆页面。

有人知道如何配置这些 portlet 吗？任何建议都会有帮助。

提前致谢。

Answer 1

据我了解，您希望在一个 .war 文件中配置多个 portlet。这非常简单，您所需要做的就是在几个 xml 文件中正确配置它们。下面我为您准备了在 6.2 liferay 版本中定义 3 个 portlet 所需的几个配置文件:

liferay-display.xml

<?xml version="1.0"?>
<!DOCTYPE display PUBLIC "-//Liferay//DTD Display 6.2.0//EN" "http://www.liferay.com/dtd/liferay-display_6_2_0.dtd">

<display>
    <category name="category.amg">
        <portlet id="first-portlet" />
        <portlet id="second-portlet" />
        <portlet id="third-portlet" />
    </category>
</display>

liferay-portlet.xml

 <?xml version="1.0"?>
<!DOCTYPE liferay-portlet-app PUBLIC "-//Liferay//DTD Portlet Application 6.2.0//EN" "http://www.liferay.com/dtd/liferay-portlet-app_6_2_0.dtd">

还要确保为 portlet.xml 中定义的每个 portlet 添加上下文文件

这就是树，它最终应该是 3 个 portlet 的样子
