iBatis简单实践

今天我实践了下ibatis框架，感觉也不错，很简单。嘻嘻，大家也尝试一下吧

ibatis下载地址：http://code.google.com/p/mybatis/downloads/detail?name=ibatis-2.3.4.726.zip&can=1&q=

数据库MYSQL下载地址 ：http://dev.mysql.com/downloads/

Connector 下载地址：http://dev.mysql.com/downloads/connector/

数据库SQL

CREATE TABLE `person` (
  `id` bigint(20) NOT NULL auto_increment,
  `name` varchar(20) default NULL,
  `version` int(11) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=101 DEFAULT CHARSET=utf8;

package com.java.chenhailong;

import java.io.Reader;
import java.util.List;

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

public class Main {
	public static void main(String args[]) throws Exception {
        String resource = "sqlMapsConfig.xml";
        Reader reader = Resources.getResourceAsReader(resource);
        SqlMapClient sqlMap = SqlMapClientBuilder.buildSqlMapClient(reader);

        // 検索処理
        List<Person> personList = (List<Person>) sqlMap.queryForList("getPerson");
        for(Person people : personList){
        	System.out.println("People Name:"+people.getName());
        }
    }
}

 上面是主函数

 得到PeopleList，然后进行分析。

package com.java.chenhailong;

/**
 * 
 * @author cnchenhai
 * 
 */
public class Person {

	private int id;

	private String name;

	private int version;

	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 getVersion() {
		return version;
	}

	public void setVersion(int version) {
		this.version = version;
	}

}
