使用abator搭建ibatis dao框架

经过我十次以上的实验,abator(新版本叫做ibator)还是1.0.0版本好用,自动生成vo,dao,impl,xml文件,而且能够自动生成Example类,并且该类自动继承vo里面的对应类.

用1.1.0发现Example不能自动继承vo里面的类,

1.2.1版本变化太大,有些生成的东西并不方便

废话少说,先建库,采用mysql

create database abator_test;

CREATE TABLE `person` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL,
  `age` int(11) DEFAULT NULL,
  `sex` varchar(255) DEFAULT NULL,
  `password` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
)

下面建立一个java project,名字就叫做abator吧,然后在项目上点右键,new-->other-->Abator for IBATIS Configuration File,文件就放在/abator/src下面,文件名不变

下面是配置文件内容<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE abatorConfiguration PUBLIC "-//Apache Software Foundation//DTD Abator for iBATIS Configuration 1.0//EN"
  "http://ibatis.apache.org/dtd/abator-config_1_0.dtd">
<abatorConfiguration  generatorSet="Java5">
  <abatorContext>    <!-- TODO: Add Database Connection Information -->
    <jdbcConnection driverClass="com.mysql.jdbc.Driver"
        connectionURL="jdbc:mysql://localhost:3306/abator_test"
        userId="root"
        password="root">
      <classPathEntry location="D:/mysql-connector-java-5.0.8-bin.jar" />
    </jdbcConnection>
    <javaModelGenerator targetPackage="vo" targetProject="abator" />
    <sqlMapGenerator targetPackage="vo" targetProject="abator" />
    <daoGenerator type="IBATIS" targetPackage="dao" targetProject="abator" />
    <table schema="" tableName="person"/>
  </abatorContext>
</abatorConfiguration>

然后在配置文件上面点击右键,选择"Generate IBATIS Artifacts",接着abator就会根据数据库自动生成对应的vo.dao等文件了

然后继续写test/ibatis_config.xml文件,配置ibatis的信息<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE sqlMapConfig PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
<settings cacheModelsEnabled="true" enhancementEnabled="true" lazyLoadingEnabled="true" maxRequests="256" maxSessions="100" maxTransactions="100" useStatementNamespaces="true"/>
	<!-- 配置数据源 -->
	<transactionManager type="JDBC" commitRequired="false">
		<dataSource type="SIMPLE">
			<!-- 驱动 -->
			<property name="JDBC.Driver" value="com.mysql.jdbc.Driver"/>
			<!-- 连接 -->
			<property name="JDBC.ConnectionURL" value="jdbc:mysql://localhost:3306/abator_test"/>
			<!-- 登录名 -->
			<property name="JDBC.Username" value="root"/>
			<!-- 密码 -->
			<property name="JDBC.Password" value="root"/>
			<property name="Pool.MaximumActiveConnections" value="10" />
			<property name="Pool.MaximumIdleConnections" value="5" />
			<property name="Pool.MaximumCheckoutTime" value="120000" />
			<property name="Pool.TimeToWait" value="500" />
			<property name="Pool.PingQuery" value="select 1 from sample" />
			<property name="Pool.PingEnabled" value="false" />
			<property name="Pool.PingConnectionsOlderThan" value="1" />
			<property name="Pool.PingConnectionsNotUsedFor" value="1" />
		</dataSource>
	</transactionManager>
	<!-- 固定表映射 -->
	<sqlMap resource="vo/person_SqlMap.xml"/>
</sqlMapConfig>

再加一个test/dao.xml文件,用于配置ibatis dao框架的dao

<?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">
<daoConfig>
  <context>
    <transactionManager type="SQLMAP">
      <property name="SqlMapConfigResource" value="test/ibatis_config.xml" />
    </transactionManager>
    <dao interface="dao.PersonDAO" implementation="dao.PersonDAOImpl" />
  </context>
</daoConfig>

截下来是一个读取配置文件的类,然后返回DaoManager,文件路径为test/DAOConfig.java

package test;
import java.io.Reader;
import java.util.Properties;
import com.ibatis.common.resources.Resources;
import com.ibatis.dao.client.DaoManager;
import com.ibatis.dao.client.DaoManagerBuilder;
public class DAOConfig {
	private static final String resource="test/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) {
			// TODO Auto-generated catch block
			new RuntimeException("Could not initialize DaoConfig.  Cause: " + e, e);
		}
		return null;	
	}
}

 最后来一个测试类test/Test.java

package test;

import vo.Person;

import com.ibatis.dao.client.DaoManager;

import dao.PersonDAO;

public class Test {

    public static void main(String[] args) {
	DaoManager daoManager = DAOConfig.getDaoManager();
	PersonDAO personDao = (PersonDAO) daoManager.getDao(PersonDAO.class);
	Person p = personDao.selectByPrimaryKey(1);
	System.out.println(p.getName());
    }
    
}

OK了,这样就用ibatis dao做了一个最简单的例子,数据库以及各种文件都在附件里面,所需的四个包全在里面
