mybatis_3_使用xml构建SqlSeesionFactory

使用xml构建SqlSeesionFactory,分为两步:

第一步:创建一个XML配置文件;

第二步:创建SqlSessionFactory实例;

示例:

第一步:创建mybatis-config2.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <environments default="development">
        <environment id="development">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="org.postgresql.Driver"/>
                <property name="url" value="jdbc:postgresql://xx.xx.xx.xx:5432/database_name"/>
                <property name="username" value="${username}"/>
                <property name="password" value="${password}"/>
            </dataSource>
        </environment>
    </environments>
</configuration>

第二步:创建SqlSessionFactory实例

package tk.mybatis.simple.model;

import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;

import java.io.IOException;
import java.io.InputStream;

public class SqlSessionFactoryTest {
    public static void main(String[] args) throws Exception {
        String resource = "mybatis-config2.xml";
        InputStream inputStream = Resources.getResourceAsStream(resource);
        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
    }
}

 文件结构:
