Liferay开发学习Part4：portlet工程结构

由 我的未来我决定 提交于 2019-11-27 14:00:24
src:源代码包 web.xml:和普通的Web工程的web.xml一样 build.xml:ant的构建文件，不需要修改继承自SDK portlet.xml:portlet定义的描述文件，这里定义了portlet的名称、初始化参数、模式类型、portlet相关信息、权限等；此文件中可以看到view-template对应的XXX.jsp，当我们在liferay里面添加portlet后，看到的页面内容就是XXX.jsp的内容 liferay-portlet.xml:定义Portlet默认可用的用户组、默认模板、是否支持多个实例等。这个文件中的 portlet-name 必须匹配 portlet.xml 中的 portlet- name。 liferay-display.xml:描述portlet所属类别 来源： oschina 链接： https://my.oschina.net/u/589482/blog/104936

Passing array from .jsp to javascript function

由 雨燕双飞 提交于 2019-11-27 07:10:09
问题 I have a Liferay portlet where I pass a String array from action phase to render phase in my .jsp file. I am able to access the array and iterate through it like this: <c:forEach var="item" items="${arrayItems}"> <p>${item}</p> </c:forEach> This is just to check that passing the data works fine... However, I would like to pass this whole array to my javascript function (that handles rendering the data to canvas). Any idea how to do this? So far, I have tried the following: <% String[] items;

respond to http request with json object in portlet

由 谁说胖子不能爱 提交于 2019-11-27 05:18:38
I am a beginner in liferay portlet development and I am developing a portlet that receives a http get request, processes some information and than it has to return a json object. My problem is that my portlet sends a whole html page instead of just the json object. This is my code: HttpServletResponse servletResponse = PortalUtil.getHttpServletResponse((renderResponse)); servletResponse.setHeader("Content-type", "application/json"); servletResponse.setCharacterEncoding("application/json"); PrintWriter out = servletResponse.getWriter(); out.write(EntityUtils.toString(responseEntity)); out.flush

Liferay portal（三）新建Portlet

由 。_饼干妹妹 提交于 2019-11-27 00:43:10
新建Liferay工程的时候会发现可以选择：Portlet模式，Hook模式，Ext模式，Theme模式，Layout模式。分别作用：1.开发自定义的页面 2.开发核心功能 3.开发扩展功能 4.开发主题功能 5.开发布局功能。 一 Portlet工程的新建过程： 在Eclipse的Liferay视图中，new一个Liferay工程，选择portlet模式。 然后继续new一个Liferay Portlet类。建议选择默认选项。 1.接着会发现在docroot/WEB-INF/src目录下面会生成对应的portlet，一般新建的portlet是一个继承自MVCPortlet的类，MVCPortlet继承自GenericPortlet类。新建的Portlet类定义了几个重要的方法：processAction()和doView()等等。这些方法是用来响应jsp页面等请求的处理。 2.portlet建好后也会在docroot/html/portlet/下面生成对应的jsp文件。 二 其余Hook,Ext,Theme,Layout工程新建方法：直接 在Eclipse的Liferay视图中，new一个Liferay工程，然后选择对应工程的功能。 来源： oschina 链接： https://my.oschina.net/u/1039458/blog/126291
