Liferay7 BPM门户开发之39: Form表单提交的ProcessAction处理

在v6.2开始后,需要设置<requires-namespaced-parameters>false</requires-namespaced-parameters>  来避免在jsp中写<portlet:namespace/>的input前缀

在v7.0发现,注解方式是不灵的!

即  "javax.portlet.requires-namespaced-parameters=false", 无效果, 真是汗...

但我们是有办法在7.0中解决的,直接上代码

jsp:

<%@page import="com.liferay.portal.kernel.portlet.LiferayPortletMode"%>
<%@page import="com.liferay.portal.kernel.portlet.LiferayWindowState"%>
<%@ include file="/init.jsp" %>

<p>
    <b><liferay-ui:message key="com_lifiti_parts_ComLifitiPartsmvcportlet.caption"/></b>
</p>

<liferay-portlet:renderURL var="openPortletURL" copyCurrentRenderParameters="true" portletMode="<%=LiferayPortletMode.VIEW.toString() %>"
  windowState="<%=LiferayWindowState.NORMAL.toString()%>">
  <liferay-portlet:param name="param" value="参数的值"/>
</liferay-portlet:renderURL>
<c:set var="submit"><liferay-ui:message key="com_lifiti_parts_ComLifitiPartsmvcportlet.submit"/></c:set>
<a href="${openPortletURL}">Render Url created</a>

<portlet:actionURL var="sendURL" name="send">
</portlet:actionURL>  

<form action="${sendURL}" method="post" name="fm">
    <aui:input name="name" label="Name" id="name"/>
    <input type="text" id="age" name="age" />
    <input type="text" name="<portlet:namespace/>phone" />
     <input type="submit" value="${submit}"></input>
</form>

public class FirstPortlet extends MVCPortlet {
  private static final Log _log = LogFactoryUtil.getLog(FirstPortlet.class.getName());

  @Override
  public void render(RenderRequest request, RenderResponse response)
  throws PortletException, IOException {
   _log.info(" This is render method of RenderURLByLiferayTagPortlet");

    String data = request.getParameter("param");
    String data1= ParamUtil.getString(request, "param","");
    System.out.println("parameter with request.getParameter is =>"+data);
    System.out.println("parameter with ParamUtil.getString is =>"+data1);

   super.render(request, response);
  }

  @ProcessAction(name="send")
  public void ReceiveData(ActionRequest actionRequest, ActionResponse actionResponse) throws Exception {
      String name = ParamUtil.getString(actionRequest, "name");
      String age = ParamUtil.getString(actionRequest, "age");
      String phone = ParamUtil.getString(actionRequest, "phone");
          _log.info(" 开始接收数据");
          System.out.println("FirstPortlet.java  name = " + name);
          System.out.println("FirstPortlet.java  age = " + age);
          System.out.println("FirstPortlet.java  phone = " + phone);
      }
}

界面:

运行的结果:

name = 王昕

age =

phone = 123

我们发现age是空的,看来说明如果用input元素,那还得写<portlet:namespace/> ,要么就用AUI,应该问题会比较少
