基于struts2+spring2+ibatis2 的文章系统（续二）

根据客户要求，集成论坛系统。ok 开工。
论坛就选开源的mvnForum,我看用的人还不少。
集成的第一件事就是汉化mvnForum.前台没有话说，OOB的就支持中文。关键是管理页面需要汉化。

一 资源文件汉化
在网上找了很久，有网友汉化的资源文件。但都是针对1.0.2版本的。最新的1.1版好像加了不少功能，
资源文件里加了好多条目在1.0.2里没有。没办法只好自立更生了。

二 freemarker模板汉化
mvnForum使用了几个FTL模板，其中viewmemberpermissions.ftl里有hardcode，要改成国际化。
<#assign i = 1 >
<#list Rows as row>
  <#if row.RowType == "Header">
    <table class="tborder" width="95%" cellspacing="1" cellpadding="3" align="center">
      <tr class="portlet-section-header" align="center">
        <td nowrap>${bundle("suncms.Forum")}</td>
        <td nowrap>${bundle("suncms.Forum.Edit")}</td>
        <td nowrap>${bundle("suncms.Forum.Delete")}</td>
        <td nowrap>${bundle("suncms.Forum.Assign")}</td>
   
        <td nowrap>${bundle("suncms.Thread")}</td>
        <td nowrap>${bundle("suncms.Thread.Add")}</td>
        <td nowrap>${bundle("suncms.Thread.Moderate")}</td>
   
        <td nowrap>${bundle("suncms.Post")}</td>
        <td nowrap>${bundle("suncms.Post.Read")}</td>
        <td nowrap>${bundle("suncms.Post.Add")}</td>
        <td nowrap>${bundle("suncms.Post.Edit_Own")}</td>
        <td nowrap>${bundle("suncms.Post.Edit_Any")}</td>
        <td nowrap>${bundle("suncms.Post.Delete")}</td>
   
        <td nowrap>${bundle("suncms.Attachment")}</td>
        <td nowrap>${bundle("suncms.Attachment.Add")}</td>
        <td nowrap>${bundle("suncms.Attachment.Get")}</td>
   
        <td nowrap>${bundle("suncms.Poll")}</td>
        <td nowrap>${bundle("suncms.Poll.Add")}</td>
        <td nowrap>${bundle("suncms.Poll.Edit_Own")}</td>
        <td nowrap>${bundle("suncms.Poll.Edit_Any")}</td>
        <td nowrap>${bundle("suncms.Poll.Delete")}</td>
      </tr>
  </#if>
 
  <#if row.RowType == "Category">
    <#assign i = 1 >
    <tr class="portlet-section-subheader">
      <td colspan="21">
        <b>${row.CategoryName}</b>
      </td>
    </tr>
    <#if row.Empty >
    <tr class="portlet-section-body"><td colspan="21" align="center">${row.no_forum}</td></tr>
    </#if>
  </#if>     
  <#if row.RowType == "Forum">
    <tr <#if i%2 == 1> class="portlet-section-body" <#else> class="portlet-section-alternate" </#if> align="center">
      <td align="left">${row.ForumName}</td>
      <td><@check permission=row.EditForum/></td>
      <td><@check permission=row.DeleteForum/></td>
      <td><@check permission=row.AssignForum/></td>
     
      <td class="messageTextBold">${bundle("suncms.Thread")} &raquo;</td>
      <td><@check permission=row.AddThread/></td>
      <td><@check permission=row.ModerateThread/></td>

      <td class="messageTextBold">${bundle("suncms.Post")} &raquo;</td>
      <td><@check permission=row.ReadPost/></td>
      <td><@check permission=row.AddPost/></td>
      <td><@check permission=row.EditOwnPost/></td>
      <td><@check permission=row.EditAnyPost/></td>
      <td><@check permission=row.DeletePost/></td>

      <td class="messageTextBold">${bundle("suncms.Attachment")} &raquo;</td>
      <td><@check permission=row.AddAttachment/></td>
      <td><@check permission=row.GetAttachment/></td>
     
      <td class="messageTextBold">${bundle("suncms.Poll")} &raquo;</td>
      <td><@check permission=row.AddPoll/></td>
      <td><@check permission=row.EditOwnPoll/></td>
      <td><@check permission=row.EditAnyPoll/></td>
      <td><@check permission=row.DeletePoll/></td>
    </tr>
    <#assign i = i+1> 
  </#if>
  <#if row.RowType == "Footer">  
    <#if row.checkNoCategory>
        <tr class="portlet-section-body">
          <td colspan="21" align="center">${row.no_category}</td>
        </tr>
    </#if>
    </table>
  </#if>
</#list> 
<#macro check permission>
  <#if permission>
    <font color="#008000">Yes</font>
  <#else>
    <font color="#FF0080">No</font> 
  </#if>
</#macro

对应的要修改ftlCategoryTreeListener.java,把国际化信息传到模板中
public void init(Template template) {
        this.template = template;
        html = new StringWriter();
        root = new HashMap();
        root.put("Rows", rows);
       
        ResourceBundle RESOURCE_BUNDLE = ResourceBundle.getBundle("mvnForum_i18n");
        ResourceBundleModel rsbm = new ResourceBundleModel(RESOURCE_BUNDLE,new BeansWrapper());
        root.put("bundle", rsbm);
    }

三 权限管理的汉化
汉化参照http://www.shorelinesolution.com/forum/viewthread?thread=137 里做的。同样的他也是基于1.0.2 做的，他提供的代码直接在1.1里使用会报错，原因也是条目比1.1里的少。修改很简单，把1.1里的AbstractPermission类里的getDescription方法拷出来修改即可。

这时 权限管理界面都是中文了，但是有几个图片的ALT信息还是英文的，继续：
修改MyUtil。java中的getIndividualPermission方法，把hardcode的英文换成国际化。为了不影响其它代码，把该方法复制 改名一份。

public static StringBuffer getIndividualPermissionFsunCMS(int combinePers, boolean globalPermission,String localeName) throws BadInputException {

        StringBuffer indivialPermissions = new StringBuffer();
        int[] individualForumPermissionArray = null;
       
        Locale locale = null;
if(localeName.length()>2){
String language = localeName.substring(0,2);
String country = localeName.substring(3);
locale = new Locale(language, country);
} else {
locale = new Locale(localeName);
}

       
        switch (combinePers) {

        case MVNForumPermission.PERMISSION_SYSTEM_ADMIN:
            //indivialPermissions.append("This permission includes all individual permissions");
        String stmp=MVNForumResourceBundle.getString(locale, "suncms.permission.alt_all");
        indivialPermissions.append(stmp);
        break;

        case MVNForumPermission.PERMISSION_FORUM_ADMIN:
            if (globalPermission) {
                individualForumPermissionArray = MVNForumPermission.individualForumAdminPermissionArray;
            } else {
                individualForumPermissionArray = MVNForumPermission.individualForumAdminLimitPermissionArray;
            }
            break;

        case MVNForumPermission.PERMISSION_FORUM_MODERATOR:
            if (globalPermission) {
                individualForumPermissionArray = MVNForumPermission.individualForumModeratorPermissionArray;
            } else {
                individualForumPermissionArray = MVNForumPermission.individualForumModeratorLimitPermissionArray;
            }
            break;
           
        case MVNForumPermission.PERMISSION_POWER_USER:
            if (globalPermission) {
                individualForumPermissionArray = MVNForumPermission.individualPowerUserPermissionArray;
            } else {
                individualForumPermissionArray = MVNForumPermission.individualPowerUserLimitPermissionArray;
            }
            break;

        case MVNForumPermission.PERMISSION_NORMAL_USER:
            if (globalPermission) {
                individualForumPermissionArray = MVNForumPermission.individualNormalUserPermissionArray;
            } else {
                individualForumPermissionArray = MVNForumPermission.individualNormalUserLimitPermissionArray;
            }
            break;
           
        case MVNForumPermission.PERMISSION_LIMITED_USER:
            if (globalPermission) {
                individualForumPermissionArray = MVNForumPermission.individualLimitedUserPermissionArray;
            } else {
                individualForumPermissionArray = MVNForumPermission.individualLimitedUserLimitPermissionArray;
            }
            break;
           
        default:
            throw new BadInputException("This permission is invalid");
           
        } // end switch
       
        if (individualForumPermissionArray != null) {
            //indivialPermissions.append("This permission includes the individual permission: &lt;br /&gt;");
        String stmp=MVNForumResourceBundle.getString(locale, "suncms.permission.alt");
            indivialPermissions.append(stmp+" &lt;br /&gt;");
        indivialPermissions.append("&lt;ul&gt;");
            for (int i = 0; i < individualForumPermissionArray.length; i++) {
                //indivialPermissions.append("&lt;li&gt;").append(AbstractPermission.getDescription(individualForumPermissionArray[i])).append("&lt;/li&gt;");
            indivialPermissions.append("&lt;li&gt;").append(LocalizedPermission.getDescription(individualForumPermissionArray[i],localeName)).append("&lt;/li&gt;");
            }
            indivialPermissions.append("&lt;/ul&gt;");
        }
       
        return indivialPermissions;
    }


四 修改JSP页面。
这个很简单，看到hardcode的英文，就用<fmt:message key="mvnforum.common.not_applicable"/> 语句换成国际化即可。

至此汉化完成。下一步集成用户。
