Ibatis,Spring整合（注解方式注入）

本文主要是介绍Ibatis,Spring整合（注解方式注入），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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;@PostConstructpublic 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
