Question

尝试为Spring MVC portlet设置值：actionURL portlet：param但由于某种原因EL不解析JSTL。请参阅下面的Message.java和MessageForm.java的详细信息，Message.java实现了equals（）和hascode（），在WebSphere Portal Server v8.0和JDK 1.6中作为Spring MVC Portlet运行。

这是我的JSP：

<c:forEach items="${messageForm.messageList}" var="message" varStatus="status">   
      <HTMLWRAPPER name="Message_Repeat">
      <tr sequence_class="tableRowPrimary,tableRowAlternate">                   
        <td class="descriptionCell" width="150" align="Center"><form:hidden path="messageList[${status.index}].subject"/>
        <a href='
            <portlet:actionURL>
            <portlet:param name="action" value="detail"/>
            <portlet:param name="id" value="${message.id}"/>                                            
            </portlet:actionURL>'><c:out value="${message.subject}"/></a>
       </td>                                
      </tr>
      </HTMLWRAPPER> 
   </c:forEach>

使用Spring MVC portlet v3.2.8及以下版本是taglibs：

<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>

Message.java

public class Message implements Serializable {
    private static final long serialVersionUID = 1L;
    Integer id;
    String type;
    String subject;
    String receiveDate;
    String expireDate;
    boolean readFlag;
    boolean deleteFlag;
    String body;
    ArrayList<Attachment> attachmentList;
    Integer attachmentCount;
    String toAddress;
    String fromAddress = "From Online";

    public String getToAddress() {
        return toAddress;
    }


    public void setToAddress(String toAddress) {
        this.toAddress = toAddress;
    }

    public String getFromAddress() {
        return fromAddress;
    }

    public void setFromAddress(String fromAddress) {
        this.fromAddress = fromAddress;
    }   

    public ArrayList<Attachment> getAttachmentList() {
        return attachmentList;
    }

    public void setAttachmentList(ArrayList<Attachment> attachmentList) {
        this.attachmentList = attachmentList;
    }

    public String getBody() {
        return body;
    }

    public void setBody(String body) {
        this.body = body;
    }

    public Integer getAttachmentCount() {
        return attachmentCount;
    }

    public void setAttachmentCount(Integer attachmentCount) {
        this.attachmentCount = attachmentCount;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getSubject() {
        return subject;
    }

    public void setSubject(String subject) {
        this.subject = subject;
    }

    public String getReceiveDate() {
        return receiveDate;
    }

    public void setReceiveDate(String receiveDate) {
        this.receiveDate = receiveDate;
    }

    public String getExpireDate() {
        return expireDate;
    }

    public void setExpireDate(String expireDate) {
        this.expireDate = expireDate;
    }

    public boolean isDeleteFlag() {
        return deleteFlag;
    }

    public void setDeleteFlag(boolean deleteFlag) {
        this.deleteFlag = deleteFlag;
    }   

    public boolean isReadFlag() {
        return readFlag;
    }

    public void setReadFlag(boolean readFlag) {
        this.readFlag = readFlag;
    }

    @Override
    public boolean equals(Object object) {
        boolean result = false;
        if (object == null || object.getClass() != getClass()) {
            result = false;
        } else {
            Message message = (Message) object;
            if (this.getType() == message.getType()
                    && this.getId() == message.getId()) {
                result = true;
            }
        }
        return result;
    }

    @Override
    public int hashCode() {
        int hash = 3;
        hash = 7 * hash + this.id.hashCode();
        hash = 7 * hash + this.subject.hashCode();
        return hash;
    }
}

MessageForm.java

public class MessageForm implements Serializable {
    private static final long serialVersionUID = 1L;    

    public ArrayList<Message> messageList = new ArrayList<Message>();

    public String delMsgConf;   

    public String getDelMsgConf() {
        return delMsgConf;
    }

    public void setDelMsgConf(String delMsgConf) {
        this.delMsgConf = delMsgConf;
    }

    public ArrayList<Message> getMessageList() {
        return messageList;
    }

    public void setMessageList(ArrayList<Message> messageList) {
        this.messageList = messageList;
    }
}

这是控制器：

@ActionMapping(params = "action=detail")
    public void detailMessage(@ModelAttribute("messageForm") MessageForm messageForm, BindingResult result, Model model,@RequestParam(required=false, value="id") String id, ActionRequest actionRequest,ActionResponse actionResponse) throws Exception {
        ArrayList<Message> messages = messageForm.getMessageList();
        HttpServletRequest servletRequest = PortletUtils.getHttpServletRequest(actionRequest);
        String sessionId = servletRequest.getSession().getId();
        String messageId = actionRequest.getParameter("id");

打印出messageId时，它只会将${message.id}显示为值 - 任何想法我做错了什么？

portlet：param不评估EL标记
