UserDAO.java接口 

  package com.tq365.samples.ibatis.dao;


import org.springframework.stereotype.Repository;

import com.tq365.samples.ibatis.model.User;
import com.tq365.sqmples.util.Pages;

/**
* UserDAO 接口
*/
@Repository
public interface UserDAO {
/**
* 通过ID查询
* @param id
* @return
*/
public User findUserById( int id);
/**
* 通过ID删除
* @param id
*/
public void deleteUserById( int id);

public void addUser(User user);
/**
* 查询指定的User对象
* @param user
* @return
*/
public User findUser(User user);
/**
* 通过用户名分页查询
* @param username
* @return
*/
public Pages < User > findUsersByUsername(String username, int pageNo);

/**
* 所有User对象分页
* @param pageNo
* @return
*/
public Pages < User > findAllPageUser( int pageNo);

}

BaseDao.java 

  package com.tq365.samples.ibatis.dao;

import javax.annotation.PostConstruct;
import javax.annotation.Resource;

import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;

import com.ibatis.sqlmap.client.SqlMapClient;

/**
* BaseDao,Dao需继承此Dao
* @author archie2010
* since 2011-3-3 下午02:52:36
*/
public class BaseDao extends SqlMapClientDaoSupport{

@Resource(name = " sqlMapClient " )
private SqlMapClient sqlMapClient;

@PostConstruct
public void initSqlMapClient(){
super .setSqlMapClient(sqlMapClient);
}
}

  

@PostConstruct注解 
    在方法上加上注解@PostConstruct，这个方法就会在Bean初始化之后被Spring容器执行（注：Bean初始化包括，实例化Bean，并 装配Bean的属性（依赖注入））。它的一个典型的应用场景是，当你需要往Bean里注入一个其父类中定义的属性，而你又无法复写父类的属性或属性的 setter方法时
