无法处理 portlet 操作阶段

Question

我有一个基本的 Liferay portlet 并使用 Spring MVC。我只有一个控制器用于 portlet 的 VIEW 模式，并且只有一种形式。当我提交表单时，不会处理操作阶段。

GraphViewController.java

package graphui;

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.portlet.ModelAndView;
import org.springframework.web.portlet.bind.annotation.ActionMapping;
import org.springframework.web.portlet.bind.annotation.RenderMapping;

/**
 *
 * Controller for VIEW mode of portlet.
 */
@Controller("graphViewController")
@RequestMapping(value = "VIEW")
public class GraphViewController{

    private static final String MODEL_KEY_NAME = "name";
    private static final String MODEL_KEY_AGE = "age";
    private static final String MODEL_KEY_EMAIL = "email";
    private Person repository = new Person("pete", 33, "pete@pete.com");
    Gson gson = new GsonBuilder().setPrettyPrinting().create();
    private static final Logger logger = Logger.getLogger(GraphViewController.class);

    @ActionMapping(GraphUIConstants.SUBMIT_FORM)
    public void handleActionRequest(ActionRequest request, ActionResponse response)throws Exception {

            logger.info("action phase executed");

            if (request.getParameter("name") != null)
                repository.setName(request.getParameter("name"));
            if (request.getParameter("age") != null)
                repository.setAge(Integer.parseInt(request.getParameter("age")));
            if (request.getParameter("email") != null)
                repository.setEmail(request.getParameter("email"));

    }

    @RenderMapping
    public ModelAndView handleRenderRequest(RenderRequest request, RenderResponse response, ModelMap model) {

      logger.info("render phase executed");  

      model.addAttribute(MODEL_KEY_NAME, gson.toJson(repository.getName()));
      model.addAttribute(MODEL_KEY_AGE, gson.toJson(repository.getAge()));
      model.addAttribute(MODEL_KEY_EMAIL, gson.toJson(repository.getEmail()));
      return new ModelAndView("index", model);
    }

}

Answer 1

"action phase is not handled"是什么意思？直接进入渲染阶段？或者您的日志中是否有某种异常？

否则无法理解原因... 乍一看一切似乎都还好...顺便问一下，您是否尝试以这种方式修改您的 actionUrl？

<portlet:actionURL var="submitForm">
    <portlet:param name="action" value="validateRequest"></portlet:param>
</portlet:actionURL>

并且，之前，您是否在 JSP portlet 标签库中导入？

<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet"%>
