Struts2 的datetimepicker Taglib�Q�在使用freemarker做result type时的问题

mmwy — Fri, 20 Apr 2007 02:26:00 GMT

struts 2.0.6GA开始试螃蟹�Q�照着struts2的tag文档写成<@s.datetimepicker/>�Q�结果老是报错

211672 [http-8080-Processor25] ERROR freemarker.runtime -
on line 7, column 17 in admin/index.ftl s.datetimepicker not found.
The problematic instruction:
----------
==> user-directive s.datetimepicker [on line 7, column 17 in admin/index.ftl]
----------

Java backtrace for programmers:
----------
freemarker.core.InvalidReferenceException: on line 7, column 17 in admin/index.ftl s.datetimepicker not found.

试着google一下，正好有�h也提交了�q�个bug�Q�改�?<@s.dateTimePicker />�Q�问题解�?br />

The fix is as follows:

In struts2-core-2.0.6:
org.apache.struts2.views.freemarker.tags.StrutsModels

has a method
getDateTimePicker()

Which should be re-named:
getDatetimepicker()

to match with the naming convention.

感谢google�Q�感�?webwork2.2.2的富文本�~�辑器的不完��解��x��?/a>"一文，感谢李李。当�Ӟ��最应该感谢的是开源（刨源代码刨出来的�Q��?/p>

1、解�?webwork/*的�\径问�?br />解决办法见�?a title="http://m.tkk7.com/mmwy/archive/2006/08/18/64234.html" href="/mmwy/archive/2006/08/18/64234.html">http://m.tkk7.com/mmwy/archive/2006/08/18/64234.html�?br />BTW�Q�也可以象�?a title="不完��解��x��? href="/quaff/archive/2006/03/26/37485.html%20">不完��解��x��?/a>”一文中描述的一��P��设webwork.serve.static=false�Q�将static/下的东西拯��/webwork目录下�?/p>

2、重写（�l�承�Q�DefaultRichtexteditorConnector�c�，解决无法在windows�q�_��上创建目录的问题

1 public class RichtexteditorConnector extends DefaultRichtexteditorConnector {
2    /**

4    * overriding methods
5    * (non-Javadoc)
6    * @see com.opensymphony.webwork.components.DefaultRichtexteditorConnector#calculateActualServerPath(java.lang.String, java.lang.String, java.lang.String)

8    protected String calculateActualServerPath(String actualServerPath,
9       String type, String folderPath) throws Exception {
10     String path = StringUtils.replaceChars( " file:/// "
11          + servletContext.getRealPath( " / " + actualServerPath), ' \\ ' , ' / ' );
12     makeDirIfNotExists(path);
13     path = path.endsWith( " / " )
14        ? path

20
21    public void setServletContext(ServletContext servletContext) {
22      this .servletContext = servletContext;
23   }
24 }

3、配�|�webwork.xml�Q�解决上传�\径自定义问题�Q�actualServerPath参数�Q�默认的使用DefaultRichtexteditorConnector�c�M��protected String _actualServerPath = "/com/opensymphony/webwork/static/richtexteditor/data/";的定义）�Q�解册��取上传文件url路径问题�Q�默认的使用AbstractRichtexteditorConnector�c�M��String _serverPath = "/webwork/richtexteditor/data/";的定义）

1      < package
2          name ="richtexteditor-browse"
3         extends ="webwork-default"
4         namespace ="/webwork/richtexteditor/editor/filemanager/browser/default/connectors/jsp" >
5          < action
6              name ="connector"
7             class ="com.mmwy.weblogic_sitemesh.util.RichtexteditorConnector"
8             method ="browse" >
9              < result
10                  name ="getFolders"
11                 type ="richtexteditorGetFolders" />

21              < param name ="actualServerPath" > /upload/ param >
22              < param name ="serverPath" > /upload/ param >
23          action >

25
26      < package

36              < param name ="serverPath" > /upload/ param >
37          action >
38      package >

注意�Q�serverPath路径必须有后面的"/"�?br />
4、解册��取上传文件url只能使用80端口的问�?br />��着源码一直跟�q�，首先是DefaultRichtexteditorConnector�c�：

1      protected String calculateServerPath(String serverPath, String folderPath, String type) throws Exception {
2          // return UrlHelper.buildUrl(serverPath, _request, _response, null, _request.getScheme(), true, true, true);
3          return UrlHelper.buildUrl(serverPath + type + folderPath, _request, _response, new HashMap(), _request.getScheme(), true , true , true );
4     }

再跟�q�UrlHelper.buildUrl�Ҏ��

1      public static String buildUrl(String action, HttpServletRequest request, HttpServletResponse response, Map params, String scheme, boolean includeContext, boolean encodeResult, boolean forceAddSchemeHostAndPort) {
2         StringBuffer link = new StringBuffer();
3
4          boolean changedScheme = false ;
5
6          int httpPort = DEFAULT_HTTP_PORT;
7
8          try {
9             httpPort = Integer.parseInt((String) Configuration.get(WebWorkConstants.WEBWORK_URL_HTTP_PORT));
10         } catch (Exception ex) {
11         }
12
13          int httpsPort = DEFAULT_HTTPS_PORT;
14
15          try {
16             httpsPort = Integer.parseInt((String) Configuration.get(WebWorkConstants.WEBWORK_URL_HTTPS_PORT));
17         } catch (Exception ex) {
18         }
19

因此�Q�解册��个问题的�Ҏ��很简单，只要在webwork.properties中设webwork.url.http.port = 8080卛_��?br />
5、语�a�问题
RichTextEditor标记autoDetectLanguage默认��gؓtrue�Q�在中文环境下��?editor/lang/zh.js�Q�显�C�繁体中文字�W�，而简体中文应该��用zh-cn.js�Q�因此，应设�|�defaultLanguage="zh-cn"�?/p>

1              < @ww .richtexteditor
2                 theme ="simple"
3                 defaultLanguage ="zh-cn"
4                 width ="750"
5                 height ="500"
6                 name ="description4" />

在网上google半天也没见�h解决�Q�还是看了FilterDispatcher的源码才解决�Q�特地脓到blog上，备忘吧�?br />

在com.opensymphony.webwork.dispatcher.FilterDispatcher中有以下代码

1             if ("true".equals(Configuration.get(WebWorkConstants.WEBWORK_SERVE_STATIC_CONTENT))
2                     && resourcePath.startsWith("/webwork")) {
3                 String name = resourcePath.substring("/webwork".length());
4                 findStaticResource(name, response);
5             } else {
6                 // this is a normal request, let it pass through
7                 chain.doFilter(request, response);
8             }

也就是说�Q�只要webwork.properties文�g中webwork.serve.static=true�Q�系�l�默认）�Q��ƈ且FilterDispatcher�q�个�q��o器对/webwork/*�q�个url�q�行了处理的话，��׃��会发生��用ww2提供�?span class="content">datepicker�Ӟ��找不�?webwork/*下所有的js、image�{�资源，不得不手工拷贝webwork.jar�?/font>/com/opensymphony/webwork/static�?webwork/*的情��c�?br />
