ibatis+spring操作数据库工具类

上图是大致目录结构和所需jar包，下面贴代码

实体类：SampleBean

package fdf.bean;

public class SampleBean {
private long id;
private String name;
private byte[]  blobSample;//接收blob类型字段
private String clobSample;//接收clob类型字段
public long getId() {
	return id;
}
public void setId(long id) {
	this.id = id;
}
public String getName() {
	return name;
}
public void setName(String name) {
	this.name = name;
}
public byte[] getBlobSample() {
	return blobSample;
}
public void setBlobSample(byte[] blobSample) {
	this.blobSample = blobSample;
}
public String getClobSample() {
	return clobSample;
}
public void setClobSample(String clobSample) {
	this.clobSample = clobSample;
}

}

ibatis配置文件

1、实体类映射sql的配置文件Sample.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMap         
    PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"         
    "http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap>
<typeAlias alias="Sample" type="fdf.bean.SampleBean"/>
<resultMap class="Sample" id="resultSample">
<result property="id" column="id" />
<result property="name" column="name" />
<result property="blobSample" column="blobSample"  jdbcType="BLOB"  typeHandler="com.ibatis.sqlmap.engine.type.BlobTypeHandlerCallback" />
<result property="clobSample" column="clobSample"   jdbcType="CLOB" javaType = "java.lang.String"/>
</resultMap>
<select id="findSampleList" parameterClass="Sample" resultClass="Sample" resultMap="resultSample">
		select * from ibatis_spring_util
</select>
</sqlMap>

2、加载映射配置的文件SqlMapConfig.xml

<?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>

	<sqlMap resource="fdf/config/ibatis/Sample.xml"/>

</sqlMapConfig>

连接数据库配置文件（以本机oracle为例）jdbc.properties

driver=oracle.jdbc.driver.OracleDriver
url=jdbc\:oracle\:thin\:@127.0.0.1\:1521\:orcl
username=****
password=*****

Spring配置文件applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"       
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
     
     <context:component-scan base-package="fdf"></context:component-scan>
      
     <bean id="propertyConfigurer"
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="location">
			<value>classpath:fdf/config/oracle/jdbc.properties</value>
		</property>
	</bean>
	 
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="${driver}"/>
		<property name="url" value="${url}"/>
		<property name="username" value="${username}"/>
		<property name="password" value="${password}"/>      
        <!--initialSize: 初始化连接-->  
		<property name="initialSize" value="2"/>  
		<!--maxIdle: 最大空闲连接-->  
		<property name="maxIdle" value="2"/>  
		<!--minIdle: 最小空闲连接-->  
		<property name="minIdle" value="2"/>  
		<!--maxActive: 最大连接数量-->  
		<property name="maxActive" value="5"/>  
		<!--removeAbandoned: 是否自动回收超时连接-->  
		<property name="removeAbandoned" value="true"/>  
		<!--removeAbandonedTimeout: 超时时间(以秒数为单位)-->  
		<property name="removeAbandonedTimeout" value="180"/>  
		<!--maxWait: 超时等待时间以毫秒为单位 6000毫秒/1000等于60秒-->  
		<property name="maxWait" value="3000"/>  
		<property name="poolPreparedStatements" value="false"/>
        <property name="defaultAutoCommit" value="true"/>
	</bean>   
    
    <!-- 配置数据源 -->
	
	<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
		<property name="dataSource" ref="dataSource"/>
		<property name="configLocation">
			<value>classpath:fdf/config/ibatis/SqlMapConfig.xml</value>
		</property>	
	</bean>
	
</beans>

操作接口：SampleDao

package fdf.dao;

import java.util.List;

import fdf.bean.SampleBean;

public interface SampleDao {
public List<SampleBean> findSampleList(SampleBean sampleBean);
}

ibatis基础操作接口BaseDao

package fdf.dao;

import java.sql.SQLException;
import java.util.List;

import javax.annotation.PostConstruct;
import javax.annotation.Resource;

import org.springframework.orm.ibatis.SqlMapClientTemplate;

import com.ibatis.sqlmap.client.SqlMapClient;



public class BaseDao<T> extends SqlMapClientTemplate{

	@Resource(name = "sqlMapClient")    
	private SqlMapClient sqlMapClient;
	
	@PostConstruct        
	public void initSqlMapClient(){         
		super.setSqlMapClient(sqlMapClient);    
	} 
	
	@SuppressWarnings("unchecked")
	public List<Object> queryListNoPage(String sqlId,Object obj){
		List<Object> list = null;
		try {
			list = (List<Object>) super.getSqlMapClient().queryForList(sqlId, obj);
		} catch (SQLException e) {
			e.printStackTrace();
		}
		return list;
	}
}
接口实现类SampleDaoImpl

package fdf.dao.impl;

import java.util.List;

import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;



import fdf.bean.SampleBean;
import fdf.dao.BaseDao;
import fdf.dao.SampleDao;
@Transactional
@Service @Scope("prototype")

public class SampleDaoImpl extends BaseDao<SampleBean> implements SampleDao{

	@SuppressWarnings("unchecked")
	@Override
	public List<SampleBean> findSampleList(SampleBean sampleBean) {
		// TODO Auto-generated method stub
		return (List)queryListNoPage("findSampleList",sampleBean);
	}

}

main方法入口SampleStart

package fdf.init;

import java.util.List;

import org.apache.log4j.PropertyConfigurator;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import fdf.bean.SampleBean;
import fdf.dao.SampleDao;

public class SampleStart {
	
	

	public static void  sampleExcute(SampleBean sampleBean){
		
		AbstractApplicationContext ctx = new ClassPathXmlApplicationContext("fdf/config/spring/applicationContext.xml");
		 SampleDao sampleDao=(SampleDao)ctx.getBean("sampleDaoImpl");
		List<SampleBean>  list=sampleDao.findSampleList(sampleBean);
		for(int i=0;i<list.size();i++){
			System.out.println("id======="+list.get(i).getId());
			System.out.println("ClobSample======="+list.get(i).getClobSample());
		}
	}
	public static void main(String[] args) {
		//初始化log4j
		PropertyConfigurator.configure("log4j.properties");
		SampleBean sampleBean=new SampleBean();
		SampleStart.sampleExcute(sampleBean);
	}

}
