Ibatis+Spring的简单使用（学习中的笔记）

1、ibatis配置文件只保留如下内容

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE sqlMapConfig      
    PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"      
    "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">

<sqlMapConfig>

	<!--
		配置映射文件
	-->
	<sqlMap resource="cn/mldn/ibatis/vo/News.xml" />

</sqlMapConfig>

 2、Spring配置文件

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="org.gjt.mm.mysql.Driver">
		</property>
		<property name="url" value="jdbc:mysql://localhost/test"></property>
		<property name="username" value="root"></property>
		<property name="password" value="mysqladmin"></property>
	</bean>

	<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
		<property name="configLocation"> <value>classpath:SqlMapConfig.xml</value> </property>


	</bean>
<bean id="sqlMapClientTemplate" class="org.springframework.orm.ibatis.SqlMapClientTemplate">
		<property name="sqlMapClient">
			<ref bean="sqlMapClient" />
		</property>
	</bean>


	<bean id="newsdaoimpl" class="cn.mldn.ibatis.dao.impl.NewsDAOImpl">
		<property name="sqlMapClientTemplate">
			<ref bean="sqlMapClientTemplate" />
		</property>
      </bean>

3、实现类如下

package cn.mldn.ibatis.dao.impl;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

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

import cn.mldn.ibatis.dao.NewsDAO;
import cn.mldn.ibatis.vo.News;

public class NewsDAOImpl extends SqlMapClientDaoSupport

 implements NewsDAO {

	public boolean doCreate(News news) throws Exception {

		news.setId((Integer) this.getSqlMapClientTemplate().insert(
				"saveNews", news));
		return true;
	}

	public boolean doDelete(int id) throws Exception {
		this.getSqlMapClientTemplate().delete("deleteNewsById", id);
		return true;
	}

	public boolean doUpdate(News news) throws Exception {
		this.getSqlMapClientTemplate().update("updateNews", news);
		return true;
	}

	public List<News> findAll() throws Exception {
		List all = this.getSqlMapClientTemplate()
				.queryForList("findAllNews");
		return all;
	}

	public News findById(int id) throws Exception {
		News news = (News) this.getSqlMapClientTemplate().queryForObject(
				"findNewsById", id);
		return news;
	}

	public List<News> findAll(int cp, int ls) throws Exception {
		Map map = new HashMap();
		map.put("start", (cp - 1) * ls);
		map.put("ls", ls);
		List all = this.getSqlMapClientTemplate().queryForList(
				"findAllNewsSplit", map);
		return all;
	}


}

 

package cn.mldn.ibatis.service.impl;

import java.util.List;

import cn.mldn.ibatis.dao.NewsDAO;
import cn.mldn.ibatis.service.NewsService;
import cn.mldn.ibatis.vo.News;

public class NewsServiceImpl implements NewsService {

	private NewsDAO newsdao;

	public void setNewsdao(NewsDAO newsdao) {
		this.newsdao = newsdao;
	}

	public boolean doCreate(News news) throws Exception {
		boolean flag = false;
		flag = this.newsdao.doCreate(news);
		return flag;
	}

	public boolean doDelete(int id) throws Exception {
		boolean flag = this.newsdao.doDelete(id);
		return flag;
	}

	public boolean doUpdate(News news) throws Exception {
		boolean flag = this.newsdao.doUpdate(news);
		return flag;
	}

	public List<News> findAll() throws Exception {
		List all = this.newsdao.findAll();
		return all;
	}

	public News findById(int id) throws Exception {
		News news = null;
		news = this.newsdao.findById(id);
		return news;
	}

}

 4、Spring的配置文件中加入一下内容

<bean id="newsserviceimpl" class="cn.mldn.ibatis.service.impl.NewsServiceImpl">
		<property name="newsdao">
			<ref bean="newsdaoimpl" />
		</property>
	</bean>


<!--实务处理-->
<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource">
			<ref bean="dataSource"/>
		</property>
	</bean>


	<bean id="transactionInterceptor"
		class="org.springframework.transaction.interceptor.TransactionInterceptor">
		<property name="transactionManager">
			<ref bean="transactionManager"></ref>
		</property>
		<!-- 
			对doxxx方法进行事务处理。
			PROPAGATION_REQUIRED表示事物处理方式。
			PROPAGATION_REQUIRED：对当前方法使用同一个事务。
			该方法内的所有操作都在同一个连接下完成。如果正常执行，
			则提交，如果出现异常，自动回滚，该方法执行后自动关闭连接。
			PROPAGATION_REQUIRED_NEW：为每个操作建立一个事务，即便中间有一个失败，后面的也继续执行。
			PROPAGATION_NEVER：不处理事务
		
		 -->
		<property name="transactionAttributes">
			<props>
				<prop key="*">PROPAGATION_REQUIRED</prop>
			</props>
		</property>
	</bean>

	<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
		<property name="beanNames">
			<list>
				<value>*serviceimpl</value>
			</list>
		</property>
		<property name="interceptorNames">
			<list>
				<value>transactionInterceptor</value>
			</list>
		</property>
	</bean>
