Druid连接池_druid pom

引言：在mybatis中引入Druid连接池

1.配置pom.xml

引入Druid依赖，可以通过以下地址去查询，选择需要的版本。

<!-- https://mvnrepository.com/artifact/com.alibaba/druid -->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.1.16</version>
</dependency>

2.创建DruidDataSourceFactory

MyDruidDataSourceFactory并继承PooledDataSourceFactory，并替换数据源。

package com.qf.mybatis.part2.utils;
 
import com.alibaba.druid.pool.DruidDataSource;
import org.apache.ibatis.datasource.pooled.PooledDataSourceFactory;
 
public class MyDruidDataSourceFactory extends PooledDataSourceFactory {
    public MyDruidDataSourceFactory() {
        this.dataSource = new DruidDataSource();//替换数据源
    }
}

3.修改mybatis-config.xml

<!--连接池-->
<dataSource type="com.qf.mybatis.part2.utils.DruidDataSourceFactory"><!--数据源工厂-->
    <property name="driverClass" value="${driver}"/>
    <property name="jdbcUrl" value="${url}"/>
    <property name="username" value="${username}"/>
    <property name="password" value="${password}"/> 
  
</dataSource>
