DaozeroDAO 接口

Daozero reduces DAO codes based on Spring & iBatis. The old way is to write codes and invoke iBatis API explicitly, but daozero implements DAO interfaces in runtime, invokes iBatis API for developers atuomaticaly. Replace old DAOs with it directly.

Daozero减少了基于Spring和iBatis的DAO代码。过去的方法是编写代码并显式调用iBatis API，但是Dao-zero在运行时实现DAO接口，并为开发人员自动调用iBatis API。直接用它替换旧的DAO。
