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 { /** * 通過ID查詢 * @param id * @return */ public User findUserById(int id); /** * 通過ID刪除 * @param id */ public void deleteUserById(int id); public void addUser(User user); /** * 查詢指定的User對象 * @param user * @return */ public User findUser(User user); /** * 通過用戶名分頁查詢 * @param username * @return */ public Pages<User> findUsersByUsername(String username,int pageNo); /** * 所有User對象分頁 * @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需繼承此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註解 
    在方法上加上註解@PostConstruct，這個方法就會在Bean初始化之後被Spring容器執行（注：Bean初始化包括，實例化Bean，並 裝配Bean的屬性（依賴注入））。它的一個典型的應用場景是，當你需要往Bean裏注入一個其父類中定義的屬性，而你又無法複寫父類的屬性或屬性的 setter方法時

UserDAOimpl.java
