一。

　　

package com.imooc.mybatis.datasource;

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

/**
 * mybatis和c3p0兼容
 */
public class C3P0DatasourceFactory extends UnpooledDataSourceFactory {

    public C3P0DatasourceFactory(){
        this.dataSource = new ComboPooledDataSource();
    }
}

    <environments default="development">
        <environment id="development">
            <transactionManager type="JDBC"/>
<!--            <dataSource type="POOLED">-->
                <!--换c3p0的源-->
                <dataSource type="com.imooc.mybatis.datasource.C3P0DatasourceFactory">
