Ibatis,Spring注解方式注入sqlMapClient

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
