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
