ibatis与spring整合

 这两天一直在研究ibatis与spring的整合 一个小小的demo搞的我头晕目眩的，但程序一旦跑起来了，突然有一种豁然开朗，重见天日，感觉生活很美好的感觉！，也许，这就是那一行行的代码带给我们的不同享受吧。呵呵，废话就不多说了。

在此先引用几句别人的资料。。。

Spring通过DAO模式，提供了对iBATIS的良好支持。SqlMapClient对象是iBATIS中的主要对象，我们可以通过配置让spring来管理SqlMapClient对象的创建。

与hibernate类似，Spring提供了SqlMapClientDaoSupport对象，我们的DAO可以继承这个类，通过它所提供的SqlMapClientTemplate对象来操纵数据库。看起来这些概念都与hibernate类似。

通过SqlMapClientTemplate来操纵数据库的CRUD是没有问题的。此篇文章没有进行事务处理。

本文采用ibatis+spring+mysql 进行编写

数据库脚本如下

create database ibatis;

create table person(
  id int primary key,
  name varchar(10),
  sex int
);

create database ibatis; create table person( id int primary key, name varchar(10), sex int );

 

一：要有一个PO类

   Person.java

package po;

import java.io.Serializable;

public class Person implements Serializable{
    /**
     *
     */
    private static final long serialVersionUID = -517413165963030507L;
    /**
     *
     */
    private int id;
    private String name;
    private int sex;

    public Person(){

    }
    public Person(int id,String name,int sex){
        this.id = id;
        this.name = name;
        this.sex = sex;
    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getSex() {
        return sex;
    }
    public void setSex(int sex) {
        this.sex = sex;
    }

}

package po; import java.io.Serializable; public class Person implements Serializable{ /** * */ private static final long serialVersionUID = -517413165963030507L; /** * */ private int id; private String name; private int sex; public Person(){ } public Person(int id,String name,int sex){ this.id = id; this.name = name; this.sex = sex; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getSex() { return sex; } public void setSex(int sex) { this.sex = sex; } }

二：DAO接口类

    IAction.java

package dao;

import java.util.List;

import po.Person;

public interface IAction {
    public boolean insertPerson(Person person);   //添加
    public boolean deleteById(int id);            //删除
    public boolean updatePerson(Person person);    //修改
    public Person queryById(int id);              //根据ID查询
    public List queryAllPerson();         //查询全部
}

package dao; import java.util.List; import po.Person; public interface IAction { public boolean insertPerson(Person person); //添加 public boolean deleteById(int id); //删除 public boolean updatePerson(Person person); //修改 public Person queryById(int id); //根据ID查询 public List queryAllPerson(); //查询全部 }

 

三：DAO实现类
   

   ActionImpl.java 此类继承SqlMapClientSupport 实现IAction接口

package dao.impl;

import java.io.IOException;
import java.io.Reader;
import java.sql.SQLException;
import java.util.List;

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

import com.ibatis.common.resources.Resources;
import com.ibatis.sqlmap.client.SqlMapClient;
import com.ibatis.sqlmap.client.SqlMapClientBuilder;
import com.ibatis.sqlmap.client.SqlMapSession;

import po.Person;
import dao.IAction;

public class ActionImpl extends SqlMapClientDaoSupport implements IAction {

    //添加操作
    @Override
    public boolean insertPerson(Person person) {
        // TODO Auto-generated method stub
        getSqlMapClientTemplate().insert("insertPerson",person);
        return false;
    }

    //删除操作
    @Override
    public boolean deleteById(int id) {
        // TODO Auto-generated method stub
        getSqlMapClientTemplate().delete("deleteById", id);
        return false;
    }



    //查询全部
    @Override
    public List queryAllPerson() {
        // TODO Auto-generated method stub
        List persons = getSqlMapClientTemplate().queryForList("queryAllPerson");
        return persons;
    }

    @Override
    public Person queryById(int id) {
        // TODO Auto-generated method stub

package dao.impl; import java.io.IOException; import java.io.Reader; import java.sql.SQLException; import java.util.List; import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport; import com.ibatis.common.resources.Resources; import com.ibatis.sqlmap.client.SqlMapClient; import com.ibatis.sqlmap.client.SqlMapClientBuilder; import com.ibatis.sqlmap.client.SqlMapSession; import po.Person; import dao.IAction; public class ActionImpl extends SqlMapClientDaoSupport implements IAction { //添加操作 @Override public boolean insertPerson(Person person) { // TODO Auto-generated method stub getSqlMapClientTemplate().insert("insertPerson",person); return false; } //删除操作 @Override public boolean deleteById(int id) { // TODO Auto-generated method stub getSqlMapClientTemplate().delete("deleteById", id); return false; } //查询全部 @Override public List queryAllPerson() { // TODO Auto-generated method stub List persons = getSqlMapClientTemplate().queryForList("queryAllPerson"); return persons; } @Override public Person queryById(int id) { // TODO Auto-generated method stub

                    //自己添加实现代码
    return null;
}

@Override
public boolean updatePerson(Person person) {
    // TODO Auto-generated method stub

//自己添加实现代码 return null; } @Override public boolean updatePerson(Person person) { // TODO Auto-generated method stub

                    //自己添加实现代码
    return false;
}

//自己添加实现代码 return false; } }

四：既然是ibatis spring整合 那就必须要有ibatis的配置文件

  SqlMapConfig.xml

 

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

PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-config-2.dtd">
<sqlMapConfig>

       
SqlMapClient.xml里本应该有数据源的配置的 使用spring之后数据源的配置移植到了spring上
 
五：Person.xml
   里面配置了一下对数据的增删改查操作
xml version="1.0" encoding="UTF-8"?>

PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-2.dtd">
<sqlMap>
    <typeAlias alias="person" type="po.Person" />

    <insert id="insertPerson" parameterClass="po.Person">

           insert into person values (#id#,#name#,#sex#)
       ]]>
    insert>

    <delete id="deleteById" parameterClass="int">

           delete from person where id=#id#
        ]]>
    delete>

    <update id="updatePerson" parameterClass="po.Person">

               update person set name=#name#,sex=#sex# where id=#id#
         ]]>
    update>

    <select id="queryById" parameterClass="int" resultClass="po.Person">

              select * from person where id=#id#
         ]]>
    select>

    <select id="queryAllPerson" cacheModel="personCache" resultClass="po.Person">

               select * from person
         ]]>
    select>
sqlMap>                    
 六：下面最重要的也就是配置applicationContext.xml了
    
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:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:3306/ibatis" />
        <property name="username" value="root" />
        <property name="password" value="1" />
    bean>

    <bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
        <property name="configLocation">
            <value>SqlMapConfig.xmlvalue>
        property>


        <property name="dataSource">
            <ref local="dataSource" />
        property>
    bean>

    <bean id="personDAO" class="dao.impl.ActionImpl">

        <property name="dataSource">
            <ref local="dataSource" />
        property>


        <property name="sqlMapClient">
            <ref local="sqlMapClient"/>
        property>
    bean>


    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource">
            <ref local="dataSource" />
        property>
    bean>
beans>            SqlMapConfig.xml                        
 注释里面的必需或不是必需都是本人多次试验的，至于为什么是必需不必需 其中的原理我也不是能太讲清楚，在此先是这些写罢了。
里面的每一个节点，属性，如果不太理解，可以上网查一些其他资料。
 
七：编写测试类
   此类利用junit进行测试。只测试了部分功能。
   
package dao.impl;

import java.util.Iterator;
import java.util.List;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import po.Person;


public class ActionImplTest {
    private static ApplicationContext applicationContext = null;   //提供静态ApplicationContext
    static{
        applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml"); //实例化
    }
    //添加操作
    @Test
    public void testInsertPerson(){
        ActionImpl s = (ActionImpl)applicationContext.getBean("personDAO");
        s.insertPerson(new Person(1,"zhangsan",2));
    }

    //删除操作
    @Test
    public void testDeletePerson(){
        ActionImpl s = (ActionImpl)applicationContext.getBean("personDAO");
        s.deleteById(1);
    }

    //查询全部
    @Test
    public void testQueryAllPerson(){
        ActionImpl s = (ActionImpl)applicationContext.getBean("personDAO");
        List<Person> persons = s.queryAllPerson();
        //System.out.println(persons.size());
        Iterator<Person> ite = persons.iterator();
        while(ite.hasNext()){
            Person person = ite.next();
            System.out.print("ID: "+person.getId());
            System.out.print(" Name: "+person.getName());
            System.out.print(" Sex: "+person.getSex());
            System.out.println();
        }
    }
} package dao.impl; import java.util.Iterator; import java.util.List; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import po.Person; public class ActionImplTest { private static ApplicationContext applicationContext = null; //提供静态ApplicationContext static{ applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml"); //实例化 } //添加操作 @Test public void testInsertPerson(){ ActionImpl s = (ActionImpl)applicationContext.getBean("personDAO"); s.insertPerson(new Person(1,"zhangsan",2)); } //删除操作 @Test public void testDeletePerson(){ ActionImpl s = (ActionImpl)applicationContext.getBean("personDAO"); s.deleteById(1); } //查询全部 @Test public void testQueryAllPerson(){ ActionImpl s = (ActionImpl)applicationContext.getBean("personDAO"); List persons = s.queryAllPerson(); //System.out.println(persons.size()); Iterator ite = persons.iterator(); while(ite.hasNext()){ Person person = ite.next(); System.out.print("ID: "+person.getId()); System.out.print(" Name: "+person.getName()); System.out.print(" Sex: "+person.getSex()); System.out.println(); } } }
八：如需记录日志 则要log4j.properties
    
#log4j.rootLogger=DEBUG, stdout
#log4j.appender.stdout=org.apache.log4j.ConsoleAppender

九：已经到最后了，我觉得这最后的才是最最重要的，就是一下jar包问题
   我调试了很长时间  一大部分时间是jar问题
   在此列出一下我认为能够跑起来这个小程序所需的一下jar包
