Ibtis基本配置--[添加ibatis Dao支持]

基本配置見上篇
一.添加配置文件dao.xml

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

<!DOCTYPE?daoConfig?PUBLIC?"-//ibatis.apache.org//DTD?DAO?Configuration?2.0//EN"?"http://ibatis.apache.org/dtd/dao-2.dtd">

????<context>

????????<transactionManager?type="SQLMAP">

????????????<property?name="SqlMapConfigResource"

??????????????????????value="yidishui/daoIbatisImpl/sql/SqlMapConfig.xml"/>

????????</transactionManager>

????????<dao?interface="yidishui.dao.PersonDao"??implementation="yidishui.daoIbatisImpl.PersonDaoImpl2"/>

????</context>

</daoConfig>

二.添加DaoConfig類

package?yidishui;

import?com.ibatis.dao.client.DaoManager;

import?com.ibatis.dao.client.DaoManagerBuilder;

import?com.ibatis.common.resources.Resources;

import?java.io.Reader;

import?java.util.Properties;

public?class?DaoConfig?{

????private?static?final?String?resource?=?"yidishui/dao.xml";

????private?static?final?DaoManager?daoManager;

????static?{

????????daoManager?=?newDaoManager(null);

????}

????public?static?DaoManager?getDaoManager()?{

????????return?daoManager;

????}

????public?static?DaoManager?newDaoManager(Properties?props)?{

????????try?{

????????????Reader?reader?=?Resources.getResourceAsReader(resource);

????????????return?DaoManagerBuilder.buildDaoManager(reader,?props);

????????}?catch?(Exception?e)?{

????????????throw?new?RuntimeException("Could?not?initialize?DaoConfig.??Cause:?"?+?e,?e);

????????}

????}

}

三.修改Dao實現，添加類PersonDaoImpl2

package?yidishui.daoIbatisImpl;

import?yidishui.dao.PersonDao;

import?yidishui.domain.Person;

import?java.util.List;

import?java.sql.SQLException;

import?com.ibatis.dao.client.template.SqlMapDaoTemplate;

import?com.ibatis.dao.client.DaoManager;

public?class?PersonDaoImpl2?extends?SqlMapDaoTemplate?implements?PersonDao?{

????public?PersonDaoImpl2(DaoManager?daoManager)?{

????????super(daoManager);

????}

????public?void?insertPerson(Person?person)?throws?SQLException?{

????????insert("insertPerson",?person);

????}

????public?void?updatePerson(Person?person)?throws?SQLException?{

????????update("updatePerson",?person);

????}

????public?Person?getPersonById(int?personId)?throws?SQLException?{

????????return?(Person)?queryForObject("getPersonById",?personId);

????}

????public?void?deletePerson(int?personId)?throws?SQLException?{

????????delete("deletePerson",?personId);

????}

????public?List?allPersonList()?throws?SQLException?{

????????return?queryForList("allPersonList",?null);

????}

}

四，測試PersonDaoImpl2Test（正確行驗證）

package?yidishui.daoIbatisImpl;

import?junit.framework.*;

import?yidishui.daoIbatisImpl.PersonDaoImpl;

import?yidishui.domain.Person;

import?yidishui.dao.PersonDao;

import?yidishui.DaoConfig;

import?java.sql.SQLException;

import?java.util.List;

import?com.ibatis.dao.client.DaoManager;

public?class?PersonDaoImpl2Test?extends?TestCase?{

????DaoManager?daoManager;

????protected?void?setUp()?throws?Exception?{

????????daoManager?=?DaoConfig.getDaoManager();

????}

????public?void?testInsertPerson()?{

????????PersonDao?personDao?=?(PersonDao)?daoManager.getDao(PersonDao.class);

????????Person?person?=?new?Person();

????????person.setPersonName("yidishui");

????????person.setPersonEmail("yidishui1570@gamil.com");

????????person.setPersonAge(100);

????????try?{

????????????personDao.insertPerson(person);

????????}?catch?(SQLException?e)?{

????????????e.printStackTrace();??//To?change?body?of?catch?statement?use?File?|?Settings?|?File?Templates.

????????}

????}

????public?void?testUpdatePerson()?throws?Exception?{

????????PersonDao?personDao?=?(PersonDao)?daoManager.getDao(PersonDao.class);

????????Person?person?=?new?Person();

????????person.setPersonId(1);

????????person.setPersonName("caotao");

????????person.setPersonEmail("caotao1570@gamil.com");

????????person.setPersonAge(1100);

????????personDao.updatePerson(person);

????}

????public?void?testDeletePerson()?throws?Exception?{

????????PersonDao?personDao?=?(PersonDao)?daoManager.getDao(PersonDao.class);

????????personDao.deletePerson(1);

????}

????public?void?testAllPersonList()?throws?Exception?{

????????PersonDao?personDao?=?(PersonDao)?daoManager.getDao(PersonDao.class);

????????List?list?=?personDao.allPersonList();

????????assertTrue("list?size?is?0",?list.size()?>?0);

????????for?(int?i?=?0;?i?<?list.size();?i++)?{

????????????Person?person?=?(Person)?list.get(i);

????????????System.out.println(person.getPersonName());

????????}

????}

}
