使用场景:

当打开的Page是本身链接时候class是current样式 

demo

<a jwcid="@PageLink" page="PostEdit" scheme="http" class="ognl:(page.pageName == 'PostEdit')?'current':''">
Write Page
</a>

Tapestry4Localization本地化/国际化
1、方法1 -- 使用Tapestry

1)Home.html
<span jwcid="@Insert" value="message:required"/> //使用message前缀

或者使用ognl:messages

<span jwcid="@Insert" value="ognl:messages.format('required', '第{0}个元素','第{1}个元素')"/>

不要使用
<span jwcid="@Insert" value="ognl:getMessage('required')"/>
因为getMessage方法在T4中被@deprecated

-----the key 'title'---- will be first find in Home_zh.properties or Home.properties

if in Home.properties can not be founded

it will find WEB-INF/myapp.properties,
The specification may also have a message catalog; for instance,
for WEB-INF/myapp.application,
the files would be named WEB-INF/myapp.properties,
etc. Again, the name of the file is based on the servlet name ("myapp").

2)
myapp_zh.properties
required=u8bf7u8f93u5165{0}u7684u503c{1}

3)
Home_zh.properties
required=u8bf7u8f93u5165{0}u7684u503c{1}

2、方法2 --使用spring的MessageSource
1)利用spring加载messges_*local.properties
 <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"> 
  <!--<property name="basename" value="classpath:messages"/>-->
   <property name="basenames">
      <list>
        <value>classpath:messages</value>
      </list>
    </property>  
 </bean>
把messageSource注入到Tapestry Components/Pages中

2)BasePage.java

import org.springframework.context.MessageSource;
//need inject //or direct impl it;
public abstract BasePage extends org.apache.tapestry.html.BasePage{

 public abstract MessageSource getMessageSource();

}

3)HomePage.java extends BasePage.java

4)Home.page
  <inject property="messageSource" object="spring:messageSource" />
5)Home.html

<span jwcid="@Insert" value="ognl:messageSource.getMessage('required',new java.lang.Object [] {'Login','!'}, 'Default', null)"/>

6)messges_zh.properties
required=u8bf7u8f93u5165{0}u7684u503c{1}
------------------------------------------------------------------
7)或者再封装以下
public abstract BasePage extends org.apache.tapestry.html.BasePage{
 public abstract MessageSource getMessageSource();
 public String getCustomMessage(java.lang.String arg0,java.lang.Object[] arg1,java.lang.String arg2,java.util.Locale arg3){
  return this.getMessageSource().getMessage(arg0,arg1,arg2,arg3);
 }
}
then in the Home.html

<span jwcid="@Insert" value="ognl:getCustomMessage('required',new java.lang.Object [] {'Login','!'}, 'Default', null)"/>

Separate Tapestry4 Action Controller from  Page 

方案1
1)HomePage.java

public class HomePage extends BasePage{

 public void doAction(){
  // do foo
 }

}

2)Home.html

<form jwcid="@Form" success="listener:doAction">

<input jwcid="@Submit" lable="doAction"/>
</form>

方案2
1)HomePage.java
public class HomePage extends BasePage{

}

2)增加DoAction.java类

DoAction.java
import org.apache.tapestry.IActionListener;
import org.apache.tapestry.IComponent;
import org.apache.tapestry.IRequestCycle;

public class DoAction implements IActionListener{
 public void actionTriggered(IComponent component, IRequestCycle cycle) {
  // do foo
 }
}

3)Home.html

<form jwcid="@Form" success="bean:action">

<input jwcid="@Submit" lable="doAction"/>
</form>

4)Home.page

<bean name="action" class="DoAction"/>

方案3

1)页面
BasePage.java
public class HomePage extends BasePage{
 public static IActionListener getAction();
}

2)增加DoAction.java类

DoAction.java
import org.apache.tapestry.IActionListener;
import org.apache.tapestry.IComponent;
import org.apache.tapestry.IRequestCycle;

public class DoAction implements IActionListener{
 public void actionTriggered(IComponent component, IRequestCycle cycle) {
  // do foo
 }
}
3)规范
Home.page

<inject property="action" object="spring:action"/>

4)Home.html

<form jwcid="@Form" success="ognl:action">

<input jwcid="@Submit" lable="doAction"/>
</form>

5)spring
beans.xml

<bean id="action" class="DoAction" />

方案4
2)
DoAction.groovy

import org.apache.tapestry.IActionListener
import org.apache.tapestry.IComponent
import org.apache.tapestry.IRequestCycle

class DoAction implements IActionListener{
 void actionTriggered(IComponent component, IRequestCycle cycle) {
  // do foo
 }
}

//Action用groovy impl IActionListener并通过spring注入回给Page的abstract IActionListener getAction()

5)
beans.xml
<lang:groovy id="action" script-source="classpath:DoAction.groovy"/>
其余同方案3

Page Events

PageAttachListener--->PageValidateListener--->activateExternalPage(if implements IExternalPage)--->PageBeginRenderListener--->PageEndRenderListener--->PageDetachListener

参考 http://tapestry.apache.org/tapestry4/UsersGuide/events.html

LoginPage extends ProtectedPage extends BasePage

把登陆验证逻辑写在ProtectedPage中

package control;

import javax.servlet.http.HttpSessionEvent;

import org.apache.tapestry.PageRedirectException;
import org.apache.tapestry.callback.PageCallback;
import org.apache.tapestry.engine.state.ApplicationStateManager;
import org.apache.tapestry.event.PageEvent;
import org.apache.tapestry.event.PageValidateListener;
import org.apache.tapestry.web.WebRequest;
import org.apache.tapestry.web.WebSession;

import web.Session;

//Shamelessly taken from the VLib applicattion

public abstract class ProtectedPage extends BasePage implements
  PageValidateListener {

 public void pageValidate(PageEvent event) {
  // TODO Auto-generated method stub

  // 判断Session对象
  /*
   * Registry registry = RegistryBuilder.constructDefaultRegistry();
   * registry.getConfiguration("tapestry.state.ApplicationObjects");
   *
   *
   *
   *
   *
   *
   *
   * Login login = (Login) getRequestCycle().getPage("Login");
   *
   * login.setCallback(new PageCallback(this));
   *
   * throw new PageRedirectException(login); }
   */

  WebRequest request = event.getRequestCycle().getInfrastructure()
    .getRequest();
  event.getRequestCycle().getInfrastructure()
  .getRequest().getRemoteUser();
  
  ApplicationStateManager asm = event.getRequestCycle().getInfrastructure().getApplicationStateManager();

  Session session = (Session)asm.get("registration-session-data");
  session.getName();
  
 
  WebSession webSession = request.getSession(true);
  if (webSession.getAttribute("isLogin") != null
    && ((String) webSession.getAttribute("isLogin")).equals("Yes")) {

  } else {
   System.out.println("Session==null--->Login");
   Login login = (Login) getRequestCycle().getPage("Login");

   login.setCallback(new PageCallback(this));

   throw new PageRedirectException(login);
  }

 }
 Object getASO(HttpSessionEvent event, String asoName) {
  //Registry registry = getHivemindRegistry(event);

  return null;
 }

}

Tapestry Components 组件

参数和绑定

在web程序中，组件被设计用来一起工作，显示页面的过程大致上是把源注入到组件中，并做预处理，并最终把信息显示出来。
