hibernate synchronizer 使用问题
1.HibernateSynchronizer中无法自动生成DAO的问题
?
??? HibernateSynchronizer是当前优秀的eclipse关于hibernate的插件。用它生成hbm文件后，通过此插件的Synchronize Files功能可以自动生成对应的pojo类，然而对应的DAO却没有自动生成。其实这个插件是具有自动生成DAO的功能的。打开生成的hbm文件，在文件接近开头的部分可以看到一下一行代码：
?
<meta attribute="sync-DAO">false</meta>?
?
把false改成true,重新执行Synchronize Files功能，DAO类就同时生成了。
?
补充：用这个插件生成的Pojo有2个，而不是像Myeclipse中的hibernate功能只生成一个pojo类。原因如下：
?
<?xml version="1.0" encoding="utf-8"?><!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">?部分删除,并添加
<mapping resource="moonsky/hibernate/model/Person.hbm.xml" />
?
导致初始化(_RootDAO.initialize();)时报如下错误

解决方法,不使用Add Mapping Reference,改成手工添加
<mapping resource="moonsky/hibernate/model/Person.hbm.xml" />
?
问题解决.
