终于实现了Tapestry4 EntityForm和QueryTable的组件化

Wed, 26 Mar 2008 08:03:35 GMT

取代以前的BaseEditPage 和 BaseListingPage 两个基础抽象类,所有的Page统一继承自 BasePage（自定义的继承自org.apache.tapestry.html.BasePage）

实现BasePage的单一化

QueryTable的实现思路

传入Query和Parameters 取代掉source参数,用Query和Parameters构建一个model提供给TableView

看下demo 类

EmployeeList.java

package app.demo.web.pages;

import java.util.HashMap;
import java.util.Map;

import org.apache.commons.lang.StringUtils;
import org.apache.tapestry.IRequestCycle;
import org.apache.tapestry.event.PageBeginRenderListener;
import org.apache.tapestry.event.PageEvent;

import common.tapestry.components.table.QueryTable;
import common.tapestry.html.BasePage;

public abstract class EmployeeList extends BasePage implements
PageBeginRenderListener {

public abstract String getName();

public void pageBeginRender(PageEvent event) {
}

QueryTable getTable_1() {
return (QueryTable) getComponent("table1");
}

public void doSubmit() {
  Map map = new HashMap();
  map.put("A", "1");

  String hql = "select a from Employee a where 1=:A";
  if(StringUtils.isNotBlank(getName())){
   hql = hql +" and a.Name like :name";
   map.put("name", "%" + getName() +"%");
  }
  getTable_1().setQueryAndParameters(hql, map);
}

public void activateExternalPage(Object[] obj,IRequestCycle cycle){
super.activateExternalPage(obj, cycle);
getTable_1().setQueryAction(false);
}
}

How to use cookies in tapestry4? my Tapestry4.1.5`LoginCookiesManagerImpl

Mon, 24 Mar 2008 06:23:52 GMT

How to use cookies in tapestry4? my Tapestry4.1.5`LoginCookiesManagerImpl

思路
首先BasePage是需要登陆的 protected ,
BasePage实现org.apache.tapestry.event.PageValidateListener方法,判断asm对象Visit是否已经登陆
如没visit==null,去cookies找回用户名和密码从cycle中获得Login页面
Login页面实现common.tapestry.IConstructVisit接口。LoginPage登陆时保存用户名密码到cookies中,并对cookies的值加密,
cookies的key是baseUrl+key,取回时对cookies值解密,加密解密的password放到Application的meta信息中

实现代码如下
抽象接口LoginCookiesManager

package common.tapestry.engine;

public interface LoginCookiesManager {

String APPLICATION_META_KEY_DEFAULT_COOKIES_IS_ENCRYPTION = "common.tapestry.default-cookies-encrypt";//是否需要加密,默认加密
String APPLICATION_META_KEY_DEFAULT_COOKIES_ENCRYPTION_KEY = "common.tapestry.default-cookies-encryption-key";//加密的password

public static final String COOKIES_KEY_LOGIN_USERNAME = "USERNAME";
public static final String COOKIES_KEY_LOGIN_PASSWORD = "PASSWORD";

/**
* 将用户名和密码写入cookies
* @param username
* @param password
* @param maxAge
*/
void writeCookies(String username,String password,int maxAge);
/**
* 清除用户名和密码cookies
*/
void removeCookies();
/**
* 从cookies中获得用户名
* @return
*/
String getUsername();
/**
* 从cookies中获得密码
* @return
*/
String getPassword();
}

LoginCookiesManagerImpl 实现

package common.tapestry.engine;

import org.apache.hivemind.ApplicationRuntimeException;
import org.apache.tapestry.engine.IPropertySource;
import org.apache.tapestry.services.AbsoluteURLBuilder;
import org.apache.tapestry.services.CookieSource;
import org.apache.tapestry.web.WebRequest;
import org.jasypt.encryption.pbe.StandardPBEStringEncryptor;
import org.jasypt.exceptions.EncryptionOperationNotPossibleException;

public class LoginCookiesManagerImpl implements LoginCookiesManager {
private static StandardPBEStringEncryptor standardPBEStringEncryptor = new StandardPBEStringEncryptor();
private IPropertySource applicationPropertySource;
private CookieSource cookieSource;
private WebRequest request;
private AbsoluteURLBuilder absoluteURLBuilder;

public void setApplicationPropertySource(
   IPropertySource applicationPropertySource) {
  this.applicationPropertySource = applicationPropertySource;
  String encrypKey = getCookiesEncryptionKey();
  standardPBEStringEncryptor.setPassword(encrypKey);
}

private String decrypt(String value) {
  String tmp = value;
  try {
   tmp = standardPBEStringEncryptor.decrypt(value);
  } catch (EncryptionOperationNotPossibleException e) {
   throw new ApplicationRuntimeException("please clear your cookies");
  }
  return tmp;
}

private String encrypt(String value) {
return standardPBEStringEncryptor.encrypt(value);
}

private String getCookiesEncryptionKey() {
  String temp = applicationPropertySource
    .getPropertyValue(APPLICATION_META_KEY_DEFAULT_COOKIES_ENCRYPTION_KEY);
  return (temp != null) ? temp : "crypassword";
}

private boolean isCookiesEncryption() {
  String temp = applicationPropertySource
    .getPropertyValue(APPLICATION_META_KEY_DEFAULT_COOKIES_IS_ENCRYPTION);
  return (temp != null) ? Boolean.valueOf(temp).booleanValue() : true;
}

public void removeCookies() {
  String cookiesKeyLogin_username = generateApplicationCookiesKey_Login__Username();
  String cookiesKeyLogin_password = generateApplicationCookiesKey_Login__Password();
  cookieSource.removeCookieValue(cookiesKeyLogin_username);
  cookieSource.removeCookieValue(cookiesKeyLogin_password);
}

public void writeCookies(String username, String password, int maxAge) {
writeCookiesValue_Login__Username(username, maxAge);
writeCookiesValue_Login__Password(password, maxAge);
}

public String getUsername() {
  String value = cookieSource
    .readCookieValue(generateApplicationCookiesKey_Login__Username());
  if (isCookiesEncryption()) {
   value = decrypt(value);
  }
  return value;
}

public String getPassword() {
  String value = cookieSource
    .readCookieValue(generateApplicationCookiesKey_Login__Password());
  if (isCookiesEncryption()) {
   value = decrypt(value);
  }
  return value;
}

private void writeCookiesValue_Login__Username(String username, int maxAge) {
  String key = generateApplicationCookiesKey_Login__Username();
  String value = username;
  if (isCookiesEncryption()) {
   value = encrypt(username);
  }
  cookieSource.writeCookieValue(key, value, maxAge);
}

private void writeCookiesValue_Login__Password(String password, int maxAge) {
  String key = generateApplicationCookiesKey_Login__Password();
  String value = password;
  if (isCookiesEncryption()) {
   value = encrypt(password);
  }
  cookieSource.writeCookieValue(key, value, maxAge);
}

private String generateApplicationCookiesKey_Login__Username() {
return generateApplicationCookiesKey(COOKIES_KEY_LOGIN_USERNAME);
}

private String generateApplicationCookiesKey_Login__Password() {
return generateApplicationCookiesKey(COOKIES_KEY_LOGIN_PASSWORD);
}

private String generateApplicationCookiesKey(String key) {
String contextPath = request.getContextPath();
return absoluteURLBuilder.constructURL(contextPath + "/") + key;
}

public void setCookieSource(CookieSource cookieSource) {
this.cookieSource = cookieSource;
}

public void setRequest(WebRequest request) {
this.request = request;
}

public void setAbsoluteURLBuilder(AbsoluteURLBuilder absoluteURLBuilder) {
this.absoluteURLBuilder = absoluteURLBuilder;
}

}

hivemodule.xml配置

<?xml version="1.0"?>
<module id="common.tapestry" version="1.0.0">
<service-point id="LoginCookiesManager" interface="common.tapestry.engine.LoginCookiesManager">
<invoke-factory>
 <construct class="common.tapestry.engine.LoginCookiesManagerImpl" >
 <set-object property="cookieSource" value="infrastructure:cookieSource"/>
 <set-service property="absoluteURLBuilder" service-id="tapestry.request.AbsoluteURLBuilder"/>
 <set-service property="request" service-id="tapestry.globals.WebRequest"/>
 <set-object property="applicationPropertySource" value="service:tapestry.props.ApplicationPropertySource"/>
 </construct>
 </invoke-factory>
</service-point>

使用

在BasePage中获得该service

public LoginCookiesManager getLoginCookiesManager() {
  LoginCookiesManager svc = (LoginCookiesManager) getRequestCycle().getInfrastructure().getProperty("loginCookiesManager");
  return svc;
}

/**
* 判断用户是否已经登陆
*
* @return
*/
private boolean isUserLoggedIn() {
  Object asmVisit = this.getRequestCycle().getInfrastructure().getApplicationStateManager().get(ASM_VISIT);

  if (!(asmVisit instanceof IVisit)) {
   throw new ApplicationRuntimeException(
     "The visit class must implements " + IVisit.class);
  }
  IVisit visit = (IVisit) asmVisit;
  if (visit == null || (visit != null && !visit.isLoggedIn())) {
   IPage loginPage = getRequestCycle().getPage(PAGE_LOGIN);
   if (loginPage instanceof IConstructVisit) {
    //从cookies中找回用户名和密码
    String cookiesLoginUsername = getLoginCookiesManager().getUsername();
    String cookiesLoginPassword = getLoginCookiesManager().getPassword();
    IConstructVisit constructVisit = (IConstructVisit) loginPage;
    visit = constructVisit.doConstructVisit(this.getRequestCycle(),
      cookiesLoginUsername, cookiesLoginPassword);
   } else {
    throw new ApplicationRuntimeException("The " + PAGE_LOGIN
      + " class must implements " + IConstructVisit.class);
   }
  }
  if (visit == null)
   return Boolean.FALSE.booleanValue();
  return visit.isLoggedIn();
}

Login类必须实现如下接口
package common.tapestry;

import org.apache.tapestry.IRequestCycle;

public interface IConstructVisit {
public IVisit doConstructVisit(IRequestCycle cycle, String username,String password);
}

Tapestry4.1.5`s common Base Border Component

Mon, 24 Mar 2008 02:59:26 GMT

Tapestry4.1.5`s common Base Border Component

考虑到每个项目都必须具有Border组件,所以把这个组件提到Base项目的ext组件库
但是每个项目的基本css又各不相同,这个css可以使用Tapestry的meta提供给Border
我在{yourTapestyServlet}.application中增加
<meta key="common.tapestry.components.border.stylesheets" value="css/POJO*.css,css/sys*.css"/>
其value是一个通配符表达式,灵感来源于spring的加载*.xml的写法,","号分割多个匹配

来看我们的Border.jwc规范

Tapestry4.1.5 how to inject spring`s bean to pages

Tapestry4.1.5 how to inject spring`s bean to pages

1、in web.xml config spring

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>

<listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>

2、put the tapestry-spring-1.0.0.jar to your classpath
you can download here
http://howardlewisship.com/tapestry-javaforge/tapestry-spring/

ok you can use <inject property="userInfoService" object="spring:userInfoService"/> in your .page file
or use Annotations inject the service

but how to get the spring`s beans in the java code ?
--------------------------------------------------------------

3、config your ${yourApp}/WEB-INF/hivemodule.xml

put the springObjectProvider to the tapestry.Infrastructure

ok in your code you can

org.apache.hivemind.service.ObjectProvider springprovider springprovider = (ObjectProvider) infrastructure.getProperty("springprovider");

YourSpringBean yourSpringBean = (YourSpringBean)springprovider.provideObject(null, null, yourSpringBeanId, null);

Tapestry5的无侵入式框架实现use Annotations?

Mon, 14 May 2007 14:14:18 GMT

Tapestry5称使用JDK5的Annotations实现无侵入式的框架，我看起来Annotations依然是侵入到了类,:(

敏捷的思维正在一步步渗透到Java Framework中,现在不仅要求类与类之间要解藕，类和Framework之间也要解耦,

途径:1)硬编码,extends/implements

2)xml

3)Framework的实践约定,比如说 public void **doActionListener(),方法名称的匹配说明了这是个Action监听器,够敏捷吧

我期待的Tapestry Control BackingBean是更纯的Java类,看来这个实现除了xml + implments,只剩下Framework的约定才能实现了,毕竟不用xml,不用Annotations,不用extends/implements 你得告诉Framework container 这个BackingBean 是怎么跟template粘起来的!

DAO / Service层的划分

Sat, 28 Apr 2007 13:07:34 GMT

由于Hibernate等ORM映射tools的出现,DAO并不在直接跟数据库RDB打交道，而是多了应用服务器持久层，从广义上讲RDB也算是持久，

应用服务器对象持久层是为了能管理ORM映射的对象的状态和周期而存在的

DAO ---> Persisent ---->RDB

When customEditorConfigurer depend on propertyConfigurer

利用org.apache.commons.io.FileUtils快速读写文件

Tue, 27 Mar 2007 04:45:12 GMT

String fileName = "C://11.txt";
  File file = new File(fileName);
  String fileContent = "";
  try {
   fileContent = org.apache.commons.io.FileUtils.readFileToString(file, "GBK");
  } catch (IOException e) {
   e.printStackTrace();
  }
  fileContent +="Helloworld";
  try {
   org.apache.commons.io.FileUtils.writeStringToFile(file, fileContent, "GBK");
  } catch (IOException e) {
   e.printStackTrace();
  }

Tapestry4Localization本地/国际化

Tue, 27 Mar 2007 02:03:16 GMT

1、方法1 -- 使用Tapestry内置message

1)Home.html
 //使用message前缀

或者使用ognl:messages

不建议使用

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=\u8bf7\u8f93\u5165{0}\u7684\u503c{1}

3)
Home_zh.properties
required=\u8bf7\u8f93\u5165{0}\u7684\u503c{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="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;

public abstract BasePage extends org.apache.tapestry.html.BasePage{

public abstract MessageSource getMessageSource();
//need inject //or direct impl it;

}

3)HomePage.java extends BasePage.java

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

6)messges_zh.properties
required=\u8bf7\u8f93\u5165{0}\u7684\u503c{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

在web application 调用Spring的Beanfactory

Tue, 27 Mar 2007 01:53:42 GMT

1)配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app
 PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<context-param>
 <param-name>contextConfigLocation</param-name>
 
 <param-value>
 WEB-INF/applicationContext*.xml
 classpath:applicationContext-datasource.xml
 classpath:applicationContext-hibernate.xml
 classpath:applicationContext-dao.xml
 classpath:applicationContext-service.xml
 </param-value>
</context-param>
<listener>
 <listener-class>
 org.springframework.web.context.ContextLoaderListener
 </listener-class>
</listener>
</web-app>

2)Jsp页面中调用spring
<%
org.springframework.beans.factory.BeanFactory beanFactory = (org.springframework.beans.factory.BeanFactory)
pageContext.getServletContext().getAttribute(org.springframework.web.context.WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE);

%>
3)Servlet中调用spring

ServletContext context = this.getServletContext();
org.springframework.beans.factory.BeanFactory beanFactory = (org.springframework.beans.factory.BeanFactory)
context.getAttribute(org.springframework.web.context.WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE);

4)ClassPath加载

ApplicationContext beanFactory = new ClassPathXmlApplicationContext(
    new String[] { "applicationContext-datasource.xml",
      "applicationContext-hibernate.xml",
      "applicationContext-service-freemarker.xml",
      "applicationContext-service.xml"

});

ActiveRecord or 贫血的POJO

Mon, 26 Mar 2007 12:01:26 GMT

ActiveRecord实现Dao 和business validation 的功能似乎更能快速的开发整个项目，但他的Dao实现必须继承，导致 code 不pure

我们可以把外部的Crud操作集中到一个Container or Tier中实现，这个Container或者Tier (Persist Logic)中操作的可能不是pure 的POJO 而是Container Wapper后的ActiveRecord,我们不用去关心,交给EntityManager来管理好了

这样我们不用继承ActiveRecord Base!!

Run Jboss seam

Mon, 26 Mar 2007 08:13:07 GMT

Run Jboss seam On my computer
1、download Java SDK5 (jdk-1_5_0_11-windows-i586-p.exe), intall it and config the JAVA_HOME env
2、download JEMS installer 1.2.0.BETA3 and install JBoss AS 4.0.5 with the ejb3 profile selected
3、Download Seam and unpack it.
Edit build.properties in your Seam directory and configure the path to your JBoss AS installation directory.

4、Run Jboss AS
5、In the jboss-seam/examples/booking directory, type ant deploy and check for any error messages.
6、Point your browser to http://localhost:8080/seam-booking/ and register an account.

http://labs.jboss.com/portal/jbossseam/gettingstarted/index.html

就seam的booking demo而言
主要分了3部分

---------------------------------------------------------------------------------
view/webui -- jsp+jsf helper/taglib/components 负责收集表单信息(element language自动get set对象) 构造dto对象(就是ejb3实体对象)
Controller -- face filter and face-config.xml 请求分发
Action use jobss ejb3 Session Bean -- face-config and annotation调用business service impl
---------------------------------------------------------------------------------
Model use jobss ejb3 Entity Bean (ORM映射,DTO,Business Object Validation)
---------------------------------------------------------------------------------
Service/Dao - javax.persistence.EntityManager (数据库持久化)
---------------------------------------------------------------------------------

ORM pojo (数据库映射对象) --- business domain class领域模型(业务对象)
---Data Transfer Object(数据传输对象) -- Presentation Value Object(值对象)

"简单就是美","约定胜于配置"敏捷思想

Active Record
An object that wraps a row in a database table or view, encapsulates the database access, and adds domain logic on that data

ActiveRecord - 活动记录 :一个对象，它包装数据库表或视图中的某一行，封装数据库访问，并在这些数据上增加了领域逻辑。

ActiveRecord可以实现真正的Domain-Driven Design，或者叫Rich Domain Model

拆分
Java --- POJO(贫血的JavaBean) --- Dao ---Business Domain Logic Validation

POJO or ActiveRecord?

国有控股？邮政变银行

国有控股？邮政变银行，反正国家要养活一批人，权利和市场的结合势必会造成腐败！

About Tapestry5

Wed, 21 Mar 2007 11:58:13 GMT

1 用Filter 代替Servlet

2 组件类不再继承基类了，并且不再用abstract类了,组件类将是纯的,简单的Pojos

3 不再需要xml书写page规范和组件规范,用java注释取代书写规范

4 Changes to Tapestry component templates and classes are now picked up immediately, without any kind of restart. This will even work properly in production, not just during development.

幸运的狗

Wed, 21 Mar 2007 11:50:01 GMT

一只狗,准确来说是一只流浪狗躺在丁老师家外边的草坪上两天了·
　　丁老师前天早晨就看见了那只狗·那只狗沿着墙根走来,一拐一拐,身上脏兮兮的,奔拉着脑袋,无精打采的样子·丁老师厌恶的绕开它,甚至还下意识的用手捂了捂鼻子·中午下班回家的时候,那只狗躺在草坪上了,哀怜地望着每一个路过的人·
　 “不晓得那是谁家的狗,也没人管·”妻子说·
　　第二天,那只狗在原地一动不动·吃午饭的时候,妻子说: “那只狗真可怜,只怕快要死了·”
　　吃晚饭的时候·妻子又说起来那只狗,吩咐丁老师: “明天去买只狗窝来·”
　　丁老师把头从饭碗里抬起来,满脸狐疑地看着妻子·
　 “你看到那只狗了吗?”妻子有点激动,站起来走到窗前, “人啊,为什么这么冷漠?”
　 “好,好,我明天就去买狗窝·”丁老师买了一只金黄色的狗窝·妻子将奄奄一息的狗抱回了家·
　　洗澡,疗伤,喂食,妻子忙得不可开交·虽然腰酸背痛,可心里舒坦·
　　流浪狗真的是三生有幸,在丁老师妻子的悉心照料下,脱胎换骨,焕然一新·
　　每天丁老师与妻子外出散步,格格----丁来势给狗起的名字----必身前身后撒欢儿跑,极逗人爱·同事们都夸丁老师妻子贤贤惠,有爱心,在评五好家庭时,一致同意丁老师家当选·
　　丁老师沉浸在幸福之中·
　　这天下班回家,丁老师在传达室门口遇上了瘦骨嶙峋的老父亲·
　 “爸,你怎么找到学校来了,不是叫你不要来吗?”他把父亲领到传达室的后墙下·
　 “你妈生病了·”父亲低声说·
　 “我不是每月给了100元?”
　 “你妈一个月要吃几百元的药·”
　 “就不能找我哥?”
　 “你哥下岗一年多了,好意思开口?”
　　下课铃响了,丁老师从钱包里取出200元递给父亲, “要放学了,你快走吧·”
　 “你妈病好久了,想你呢,你抽个空回去看看·”
　 “莎莎出差了,没人给格格弄饭吃·”丁老师说完,一转身走了·
　 “格格是谁呀?”父亲望着丁老师的背影,大声问了一句·
