一、统计信息管理

二、Spring注解开发

　　1.service为例子

@Service("customerService")
@Transactional(isolation=Isolation.REPEATABLE_READ,propagation=Propagation.REQUIRED,readOnly=false)public class CustomerServiceImpl implements CustomerService {
    @Resource(name="customerDao")private CustomerDao cd;

三、EasyUI

　　1.为企业开发省去美工前端.自带一套页面的样式以及效果.

　　 json使用fastjson-1.2.8.jar。

　　主要是参考说明文档和实例来进行开发，下面增删改查为例：

　　代码：
