Generic DAO Framework

Hibernate Generic D.A.O. Framework是一个基于Hibernate实现，可扩展的通用泛型DAO框架。封装了一些常用的CRUD操作和搜索功能，并提供远程服务接口。

示例代码：

Search search = new Search();
search.addFilterEqual("name", "hibernate-generic-dao");

List<Project> list = projectDAO.search(search);

int count = projectDAO.count(search);

SearchResult<Project> result = projectDAO.searchAndCount(search);
list = result.getResult();
count = result.getTotalCount();

search.clear();
search.addField("rating", Field.OP_AVG);
int avgProjectRating = (Integer) prjoectDAO.searchUnique(search);
