问题描述
我是Liferay平台的新手.我正在尝试使用Portlet在Liferay中实现CRUD.我正在使用liferay 6.2和IDE作为开发人员工作室.
I am new in Liferay platform. I am trying to implement CRUD in Liferay using portlet. I am using liferay 6.2 and IDE as a developer studio.
我正在Developer Studio中创建具有以下值(在图像中)的项目.
I am creating project with below values (In Image) in developer studio.
当我在Developer Studio中创建项目时，我的Liferay项目浏览器中有3个项目，如下图所示.
When I am creating project in Developer studio I am getting 3 project in my Liferay project explorer which are shown in below image.
所以我的问题是为什么当我只想创建一个服务构建器portlet时为什么要创建它的三个项目.有什么用?
So my question is that why its three project are created when I only want to create one service builder portlet. What are the use of that?
任何人都可以帮忙吗?
推荐答案
所以这是Liferay with Maven的作用:它创建一个父项目(BookServicePortlet). Liferay假设，如果您要构建服务层，则还将实现一个Portlet，您可以在其中访问生成的服务.这就是为什么Liferay-Maven在您的父项目中创建2个子项目的原因.一种用于服务，另一种用于网络层.这样做是为了使您可以将服务层分发到其他portlet，而无需分发所有前端代码.如果您没有前端(我怀疑;))，则可以在BookServicePortlet-portlet中将所有内容保留为空白.
So this is what Liferay with Maven does:It creates a Parent Project (BookServicePortlet). Liferay assumes, if you want to build a service layer, you also will implement a portlet where you access the Services generated. So that's why Liferay-Maven is creating 2 SubProjects in your parent project. One for the service, and one for Web-Tier. This is done, so that you can distribute your service layer to other portlets without distributing all your front-end code. If you don't have a front-end (and I doubt that ;) ) you could just leave all blank in BookServicePortlet-portlet.
