appfuse例子一步步解析!結(jié)合eclipse3.0一起使用

Appfuse應(yīng)用的核心在于ant build任務(wù)的靈活應(yīng)用和xdoclet模板的修改與使用。重要的工具是其提供的appgen，通過對(duì)ant build任務(wù)和appgen xdocet模板的修改將appfuse與自己的項(xiàng)目進(jìn)行融合、與IDE進(jìn)行融合。所以要用appfuse，學(xué)習(xí)ant工具和xdoclet是必不可少的第一步。
前提所需的軟件
jdk1.4.2.6
tomcat5.0.28
ant1.6.2
appfuse1.82
mysql4.x

以上軟件請(qǐng)?jiān)L問
http://raibledesigns.com/wiki/Wiki.jsp?page=AppFuseQuickStart_zh
根據(jù)相關(guān)提示下載
同時(shí)對(duì)以上變量，都設(shè)置相關(guān)的HOME變量及路徑。

下面開始一步步操作完成appfuse的布署工作

1，解壓appfuse1.8.2（或更高版本），會(huì)產(chǎn)生一個(gè)appfuse的目錄。
2，打開eclipse3.0或eclipse3.1，選擇菜單，“新建工程”-->"Java Project"---->工程名"appfuse"后，指定一個(gè)工程目錄后，完成。
3，先復(fù)制第一步中appfuse目錄下所有文件，然后右鍵點(diǎn)擊"appfuse"工程名，選擇“粘貼”，把a(bǔ)ppfuse的所有的文件導(dǎo)入到appfuse工程中。
4，在eclipse下選擇"windows"菜單--->"Preference"菜單--->"ant"--->"Runtime"---->點(diǎn)“ant????? home”按鈕,設(shè)備ant-home目錄，同時(shí)復(fù)制junit.jar到ant安裝目錄下的lib目錄里
5,在安裝mysql服務(wù)器后，如果設(shè)置了密碼的話，要點(diǎn)，windows菜單--->show views---> ant 。出現(xiàn)ant工具界面，在界面上，點(diǎn)add buildfiles圖標(biāo)，把a(bǔ)ppfuse工程根目錄下的build.xml文件中附加進(jìn)來，然后再打開properties.xml文件，修改里面的root用戶的密碼為你的mysql數(shù)據(jù)庫訪問時(shí)的密碼。然后在ant菜單界面中展開target列表，選擇，setup目錄安裝所有裝備工作，
詳細(xì)ant任務(wù)可以參照http://www.kingbit.com/appfuse/index.php上所描述的ant任務(wù)詳解。
運(yùn)行ant setup-tomcat 然后再運(yùn)行，ant start-tomcat
然后在瀏覽器中打http://localhost:8080/appfuse
看看有沒有出現(xiàn)界面
操作用戶名及密碼是tomcat tomcat
6,當(dāng)上面都配置正確后，我們就來開始寫一個(gè)新的操作了，先寫個(gè)dao類下的model類
在eclipse下，展開src/dao文檔結(jié)構(gòu)，在org.appfuse.model下面，建個(gè)Person.java文件，
內(nèi)容如下圖：

/*
?* Created on 2006-5-22
?*
?* TODO To change the template for this generated file go to
?* Window - Preferences - Java - Code Style - Code Templates
?*/
package org.appfuse.model;

/**
?* @author Administrator
?*
?* TODO To change the template for this generated type comment go to
?* Window - Preferences - Java - Code Style - Code Templates
?* @hibernate.class table="person"
?*/
public class Person? extends BaseObject{
?private Long id;
?private String first_name;
?
?/**
? * @return Returns the id.
? * @hibernate.id column="id"? generator-class="increment"
???? *??????????????
? */
?public Long getId() {
??return id;
?}
?/**
? * @param id The id to set.
? */
?public void setId(Long id) {
??this.id = id;
?}
?/* (non-Javadoc)
? * @see org.appfuse.model.BaseObject#toString()
? */
?
?public String toString() {
??// TODO Auto-generated method stub
??return null;
?}
?/* (non-Javadoc)
? * @see org.appfuse.model.BaseObject#equals(java.lang.Object)
? */
?public boolean equals(Object o) {
??// TODO Auto-generated method stub
??return false;
?}
?/* (non-Javadoc)
? * @see org.appfuse.model.BaseObject#hashCode()
? */
?public int hashCode() {
??// TODO Auto-generated method stub
??return 0;
?}
?
?/**
? * @return Returns the first_name.
? * @hibernate.property column="first_name" not-null="true"
? */
?public String getFirst_name() {
??return first_name;
?}
?/**
? * @param first_name The first_name to set.
? * @spring.validator type="required" //該字段需要驗(yàn)證，用Spring的校驗(yàn)機(jī)制
? */
?public void setFirst_name(String first_name) {
??this.first_name = first_name;
?}
}

在以上代碼中注釋javadoc區(qū)域中添加上xdoclet在生成hibernate所用到的XML文件的一些O/R映射信息。

建好上以Person.java后，我們就開始利用xdoclet工具，配合ant任務(wù)，生成我們所需用到了數(shù)據(jù)庫表結(jié)構(gòu)了，
點(diǎn)ant db-create 后，可以在控制臺(tái)下看到一系列建表的語句，同時(shí)可以到mysql控制臺(tái)查看到相關(guān)信息.
表建好后，我們就開始利用appgen自動(dòng)生成appfuse所需要的其它dao操作類，manage業(yè)務(wù)類，controller控制器類及Person.hbm.xml等相關(guān)文件
。操作過程如下，到dos命令行模式下，找到工程所在的根目錄下\extras\appgen目錄，點(diǎn)運(yùn)行ant install-detailed
會(huì)根據(jù)提示，建Person及person相關(guān)文件。Build成功后，再回到eclipse下，右鍵點(diǎn)工程文件名appfuse,選擇Refresh ,再運(yùn)行ant deploy命令，再重新啟TOMCAT,這樣一個(gè)Person的添加，刪除操作功能模塊就完成了，開發(fā)就是這么easy and fast!!^_^
@spring.validator type="required" 是另外附

appgen生成的類文件如下：

PersonDAO接口類
PersonDAOHibernate接口實(shí)現(xiàn)類
PersonManager業(yè)務(wù)接口類
PersonManagerImpl.java業(yè)務(wù)接口實(shí)現(xiàn)類
PersonController.java控制器類(根據(jù)客戶端提交的請(qǐng)求，顯示的是信息列表)
PersonFormController頁面控制器類（根據(jù)客戶端提交的請(qǐng)求，修改，添加，刪除操作控制類）

注意在生成dao接口類的時(shí)候，appgen會(huì)根據(jù)Person類中的hibernate的注釋標(biāo)記，生成對(duì)應(yīng)的Person.hbm.xml文件
修改org.appfuse.dao.hibernate.applicationContext-hibernate.xml文件，
追加
?<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
??????? <property name="dataSource" ref="dataSource"/>
??????? <property name="mappingResources">

修改org.appfuse.service目錄下的，applicationContext-service.xml文件

追加以下配置

在布署公司的產(chǎn)品過程中，mine的WAR應(yīng)用，在執(zhí)行ant compile-dao過程中，會(huì)報(bào)一個(gè)，找不到org.eclipse.jta的錯(cuò)誤，
這是由于ant找不到eclipse的關(guān)于jta的插件的原因！解決辦法是，在ant架包中，把eclipse 安裝目錄下的plugns目錄下的org.eclipse.jdt.core_3.0.
（E:\eclipse\plugins\org.eclipse.jdt.core_3.0.0\）目錄中兩個(gè)jar文件加入到ant的lib目錄下！

xdoclet在執(zhí)行ant的deploy的任務(wù)時(shí)，有時(shí)候生成的XML文件格式會(huì)出現(xiàn)小小的問題，解決的辦法是修改相關(guān)的JAVA文件，然后運(yùn)行deploy腳本重新利用
xdoclet來生成相關(guān)的xml文件！直至成功！

首頁登錄在調(diào)用loginServlet時(shí)候，login.jsp頁面能正確顯示出來，但是提交到服務(wù)器的/authorize的action映射找不到，也就是找不到服務(wù)，
這是由于tomcat是啟動(dòng)在8080端口的服務(wù)，而程序中，用戶登錄的校驗(yàn)是根據(jù)properties.xml文件中，配置的
<property name="http.port" value="8080"/>這個(gè)端口號(hào)，默認(rèn)的是80端口，可以通過把TOMCAT啟動(dòng)時(shí)監(jiān)聽80端口或，修改properties.xml文件中
http.port的value="8080",就可以找到服務(wù)器響應(yīng)。注意，這里/authorize的映射,不是通過spring的IOC操作的，而是通過在web.xml文件中加入一個(gè)
?<filter>
? <filter-name>securityFilter</filter-name>
? <filter-class>net.sf.acegisecurity.util.FilterToBeanProxy</filter-class>
- <init-param>
? <param-name>targetClass</param-name>
? <param-value>net.sf.acegisecurity.util.FilterChainProxy</param-value>
? </init-param>
? </filter>
<filter-mapping>
? <filter-name>securityFilter</filter-name>
? <url-pattern>/j_security_check</url-pattern>
? </filter-mapping>

來實(shí)現(xiàn)的

但是一定要記得，文件net.sf.acegisecurity.util.FilterChainProxy是在acegi-security-x.x.x.jar包里面的，調(diào)用前一定要記得放在應(yīng)用的WEB-INF/lib/目錄下才能正常使用。

當(dāng)系統(tǒng)啟動(dòng)時(shí)會(huì)自動(dòng)加載spring配置文件中所聲明的類，在appfuse中這一聲明是放在action-servlet.xml中的，因此必須將這個(gè)文件同其他的applicationContext.xml一起在web.xml中聲明為contextConfigLocation的內(nèi)容，如下：

?? <context-param>
? <param-name>contextConfigLocation</param-name>
? <param-value>classpath*:META-INF/applicationContext-*.xml /WEB-INF/applicationContext-*.xml /WEB-INF/schedulingContext-timer.xml</param-value>
? </context-param>

?

在action-servlet.xml中定義如下（這個(gè)文件必須符合spring-beans.dtd的規(guī)范）：

<beans>???
???
??? <bean id="userAction" class="com.mywap.webwork.action.UserAction" singleton="false">
??????? <property name="userManager"><ref bean="userManager"/></property>
??? </bean>
???
??? <!-- Add additional actions here -->
</beans>

?

acegi出了0.8,改動(dòng)還真不少，原先0.7的應(yīng)用，改了一個(gè)多小時(shí)才完全升級(jí)成功。備忘一下：

1 最貼心的改變莫過于 filter chains可以放在spring 容器中加載了，再也不用在Web.XML中聲明長(zhǎng)長(zhǎng)的一串filter了。例如：

?<bean id="filterChainProxy" class="net.sf.aceGISecurity.util.FilterChainProxy">
????? <property name="filterInvocationDefinitionSource">
???????? <value>
???????? CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON
????????? PATTERN_TYPE_APACHE_ANT
??????????? /**=httpSessionContextIntegrationFilter,authenticationProcessingFilter,......
???????? </value>
????? </property>
??? </bean>

2 HttpSessionIntegrationFilter 已經(jīng)消失，使用net.sf.acegisecurity.context.HttpSessionContextIntegrationFilter取而代之，如：
??? <bean id="httpSessionContextIntegrationFilter" class="net.sf.acegisecurity.context.HttpSessionContextIntegrationFilter">
????? <property name="context"><value>net.sf.acegisecurity.context.security.SecureContextImpl</value></property>
??? </bean>

這個(gè)"context"屬性不可不設(shè)喲。

3 新增了一個(gè)功能，可以在web.xml中聲明一個(gè)HttpSessionEventPublisher context listener,想想Spring的現(xiàn)在還不很成熟的消息發(fā)布機(jī)制(AOP),主要是用來記日志。我暫時(shí)還沒用到這個(gè)功能。

?

mine在通過ant deploy任務(wù)到TOMCAT下,會(huì)把hibernate的表映射文件,連同持久化的類文件,打包成一個(gè),mine-dao.jar架包,放到web-inf/lib私有目錄下
