Portlet之间传值

2种liferay portlet 之间传至方法。

NO.1

portlet.xml

message1


		message1
		x:message1
	

对参数进行赋值的话，就是在Action中用下面这句话：
actionResponse.setRenderParameter("参数名", 参数值);
获取的话，就直接像取其它参数一下直接获取：
在Action中，String 变量 = ParamUtil.getString(request, "参数名", "默认值");
在JSP中，<%=renderRequest.getParameter("参数名")%>


NO.2

liferay-portlet.xml

		false
		false

public String index() {

		HttpServletResponse resp = ServletActionContext.getResponse();
        org.apache.struts2.portlet.servlet.PortletServletResponse struts2Resp = (org.apache.struts2.portlet.servlet.PortletServletResponse) resp;     
        
        HttpServletRequest req = ServletActionContext.getRequest();
		org.apache.struts2.portlet.servlet.PortletHttpSession strutsSession = (org.apache.struts2.portlet.servlet.PortletHttpSession) (req
				.getSession());
		
		if(Validator.isNull(message)){
			 message = (String)strutsSession.getPortletSession().getAttribute("message",PortletSession.APPLICATION_SCOPE);
		}
		strutsSession.getPortletSession().setAttribute("message", message, PortletSession.APPLICATION_SCOPE);
		return SUCCESS;
	}

	String message = (String)renderRequest.getPortletSession().getAttribute("message",PortletSession.APPLICATION_SCOPE);		renderRequest.setAttribute("message", message);
