曾有段时间，对代码生成器非常感兴趣，于是使用fmpp做了个简单的代码生成器，
生成的流程是，根据 PowerDesigner的cmd实体模型文件，生成每张表的hbm.xml,
然后再根据hbm.xml，生成对应的相关java代码，xml配置，jsp页面等文件。
大概有以下代码模板： spring-Hibernate.xml
struts-web_pojo.xml
Abstractpojo.java
pojo.java
pojoKey.java
IpojoLogic.java
pojoLogicImpl.java
spring-pojo.xml
IpojoDAO.java
pojoHibernateDAOImpl.java
compass-pojo.cmd.xml
compass-pojo.cpm.xml
pojoAddAction.java
pojoDelAction.java
pojoEditAction.java
pojoEditActionForm.java
pojoIndexAction.java
pojoSearchActionForm.java
pojoUpdateAction.java
struts-config_pojo.xml
struts-spring-pojo.xml
validator_pojo.xml
pojoindex.jspx
后来这些东西没有继续折腾了，这几天清理硬盘时发现了这些，因此在这里把代码贴出来，留作备忘。
cdm到hbm.xml 的fmpp 配置为：
config.fmpp
—————–
outputEncoding:UTF-8
sourceRoot: src
outputRoot: hbm2code
logFile: log.fmpp
data: {
pdcdmentity:xml(data/pdcdm.cdm)
}
hbm.xml的代码模板为(只实现基本的映射和复合主键判断，对于简单的单表够用，其它的没处理)：
[code]
<#ftl encoding="UTF-8" ns_prefixes={"a":"attribute","c":"collection","o":"object"} >
<@pp.setOutputEncoding encoding="UTF-8"/>
<#list pdcdmentity["Model"]["o:RootObject"]["c:Children"]["o:Model"]["c:Entities"]["o:Entity"] as et>
<#assign x = et["a:Code"]?cap_first >
<@pp.changeOutputFile name="/src/webapp/WEB-INF/hbms/"+x+".hbm.xml" />
<?xml version="1.0" encoding='UTF-8'?>
