手工書寫spring-beans.xml非常繁瑣，而且如果多個程序員同時進行一個項目的時候，即使分成多個spring文件，也很容易會產生沖突，更別說經常遇到的錯誤和程序升級問題了，還好最新的Xdoclet可以幫助我們解決這個煩惱，在最新的Xdoclet中已經包含了對srping的支持，即srpingdoclet。如下是例子：
1、下載ant，從jakarta.apache.org
安裝在c:\dev\ant，安裝過程就不詳細說了，如果ant都不懂，那看來您有些落伍了，也先別往下看了，學習一下ant先
2、下載xdoclet，當然是xdoclet.sf.net了，下載后把lib的東西放置到
c:\dev\ant\lib\xdoclet
3、java 代碼
只是個例子而已
===================================================================
XdocletMain.java :
===================================================================
| 代碼: |
/**
* Created by IntelliJ IDEA.
* User: wangzy
* Date: 2004-12-5
* @spring.bean
* id="XdocletMain"
* singleton="true"
* 上述說明,這是個spring的bean，id為XdocletMain，如果看不懂，再補習一下xdoclet
* @spring.property
* name="bean1"
* ref="Bean1"
* 上述說明，有個bean1屬性，關聯的為Bean1的spring組件
* @spring.property
* name="bean2"
* ref="Bean2"
* 同上
*/
public class XdocletMain {
public Bean1 getBean1() {
return bean1;
}
public void setBean1(Bean1 bean1) {
this.bean1 = bean1;
}
public Bean2 getBean2() {
return bean2;
}
public void setBean2(Bean2 bean2) {
this.bean2 = bean2;
}
private Bean1 bean1 = null;
private Bean2 bean2 = null;
}
|
===================================================================
Bean1.java :
===================================================================
| 代碼: |
/**
* Created by IntelliJ IDEA.
* User: wangzy
* Date: 2004-12-5
* @spring.bean
* id="Bean1"
* singleton="true"
* 聲明一個Bean1的spring組件
*/
public class Bean1 {
}
|
===================================================================
Bean2.java :
===================================================================
| 代碼: |
/**
* Created by IntelliJ IDEA.
* User: wangzy
* Date: 2004-12-5
* @spring.bean
* id="Bean2"
* singleton="true"
* 類似Bean1
*/
public class Bean2 {
}
|
===================================================================
下來當然就是最重要的ant的build.xml了，其中相關部分為：
| 代碼: |
<!--這里是xdoclet的lib,這些都不是ant的core包，所以要引進來 -->
<path id="xdoclet.class.path">
<fileset dir="c:\dev\ant\lib\xdoclet">
<include name="*.jar"/>
</fileset>
</path>
<!--這里就是生成spring-beans配置了 -->
<target name="srpingdoclet">
<!--定義springdoclet task -->
<taskdef
name="springdoclet"
classname="xdoclet.modules.spring.SpringDocletTask"
classpathref="xdoclet.class.path"
/>
<!--這里根據src下的java文件中的信息，生成spring-beans.xml到“spring/spring-beans.xml”文件中-->
<springdoclet destdir="spring">
<fileset dir="src" includes="**/*.java" />
<springxml destinationFile="spring-beans.xml" />
</springdoclet>
</target>
|
運行ant springdoclet，看看spring/spring-beans.xml文件，大功告成！！！
具體詳細信息可以看xdoclet文檔
| 代碼: |
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC
"-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans
default-autowire="no"
default-lazy-init="false"
default-dependency-check="none"
>
<bean
id="Bean1"
class="Bean1"
singleton="true"
>
</bean>
<bean
id="XdocletMain"
class="XdocletMain"
singleton="true"
>
<property name="bean1">
<ref bean="Bean1"/>
</property>
<property name="bean2">
<ref bean="Bean2"/>
</property>
</bean>
<bean
id="Bean2"
class="Bean2"
singleton="true"
>
</bean>
<!--
To include additional bean definitions for Spring in the generated
application context file, add a file to your XDoclet merge directory
called spring-beans.xml that contains the <bean></bean> markup.
-->
</beans>
