18mybatis集成c3p0与jndi

集成 c3p0
1、pom.xml 文件加入依赖
<dependency>
<groupId>c3p0</groupId>
<artifactId>c3p0</artifactId>
<version>0.9.1.2</version>
</dependency>

2、编写一个工厂， 继承UnpooledDataSourceFactory
package com.mybatis.bean;

import com.mchange.v2.c3p0.ComboPooledDataSource;
import org.apache.ibatis.datasource.unpooled.UnpooledDataSourceFactory;

/**
* Created by webrx on 2017-06-22.
*/
public class C3P0DataSourceFactory extends UnpooledDataSourceFactory {
public C3P0DataSourceFactory() {
this.dataSource = new ComboPooledDataSource();
}
}

3、mybatis-config.xml 配置一下
<?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>
<properties resource="db.properties"/>
<!-- 全局配置参数 -->
<settings>
<!-- 延迟加载总开关 -->
<setting name="lazyLoadingEnabled" value="true"/>
<!-- 设置按需加载 -->
<setting name="aggressiveLazyLoading" value="false"/>

<setting name="logPrefix" value="dao."/>
</settings>

<environments default="development">
<environment id="development">

<!--

</dataSource>
-->
<dataSource type="com.mybatis.bean.C3P0DataSourceFactory">

</dataSource>
</environment>
</environments>
