MyBatis在非Spring環境下第三方DataSource設置-Druid篇

首先在ITEye上面看到一個同標題文章，在此說明，此文並非轉載自 http://iintothewind.iteye.com/blog/2069522 ，因為這篇文章根本就是錯誤的，照着上面做，工程可以跑，但是dataSource根本不是druid的

首先說明一下我使用的各個軟件版本:

druid版本：1.0.8

<!-- mysql數據庫連接池 pool -->
<dependency>
  <groupId>com.alibaba</groupId>
     <artifactId>druid</artifactId>
     <version>1.0.8</version>
</dependency>

mybatis版本:3.2.8

<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>3.2.8</version>
</dependency>

 

 

MyBatis在非Spring環境下第三方DataSource設置  ，代碼如下：

mybatis.xml：

<?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="userDefine">
        <environment id="userDefine">
            <transactionManager type="JDBC" />
            <!-- 配置數據庫連接信息 -->
            <dataSource type="com.chenjun.mysite.common.MyselfDefineDataSourceFactory">
                <property name="driverClass" value="com.mysql.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql://localhost:3306/site-aliyun"/>
                <property name="username" value="root"/>
                <property name="password" value="123456"/>
            </dataSource>
        </environment>
    </environments>
      <mappers>
        <mapper resource="mappings/modules/sys/userDao.xml"/>
    </mappers>
</configuration>

MyselfDefineDataSourceFactory是 ，自定義datasourceFactory ，作為type屬性給上面的mybatis.xml文件

package com.chenjun.mysite.common; import org.apache.ibatis.datasource.unpooled.UnpooledDataSourceFactory; import com.alibaba.druid.pool.DruidDataSource; public class MyselfDefineDataSourceFactory extends UnpooledDataSourceFactory { public MyselfDefineDataSourceFactory() { this.dataSource = new DruidDataSource(); } }

驗證結論:

public class UserDao {
	private static final String NAME_SPACE = "com.chenjun.mysite.entity.User";
	public User test1(){
		User user = new User();
		SqlSessionFactory sqlSessionFactory;
		try {
			sqlSessionFactory = new SqlSessionFactoryBuilder().build(Resources.getResourceAsReader("mybatis.xml"),"userDefine");
			SqlSession session = sqlSessionFactory.openSession();
                        System.out.println("class="+session.getConfiguration().getEnvironment().getDataSource().getClass().getName());
			DataSource ds = session.getConfiguration().getEnvironment().getDataSource();
			if(ds instanceof DruidDataSource){
				System.out.println("Yes");
			}else{
				System.out.println("No");
			}
			user = session.selectOne(NAME_SPACE+"."+"test1");
		} catch (IOException e) {
			e.printStackTrace();
		}
		return user;
	}

}

　　最后輸出

 

class=com.alibaba.druid.pool.DruidDataSource Yes 15:55:09.817 [qtp2104354711-23] DEBUG org.apache.ibatis.transaction.jdbc.JdbcTransaction - Opening JDBC Connection 15:55:09.850 [qtp2104354711-23] INFO com.alibaba.druid.pool.DruidDataSource - {dataSource-1} inited

 

這才是集成druid的正確打開方式！！！
