MyBatis配置C3P0连接池

1.在pom.xml中添加C3P0依赖

 <dependency>
            <groupId>com.mchangegroupId>
            <artifactId>c3p0artifactId>
            <version>0.9.5.4version>
 dependency>

2.创建工厂类

/**
 * C3P0与MyBatis兼容使用的数据源工厂类
 */
public class C3P0DataSourceFactory extends UnpooledDataSourceFactory {
    public C3P0DataSourceFactory(){
        this.dataSource=new ComboPooledDataSource();
    }
}

3.在mybatis-config.xml中配置数据源

			dataSource type="datasource.C3P0DataSourceFactory">
                <property name="driverClass" value="com.mysql.cj.jdbc.Driver"/>
                <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/babytun?useUnicode=true&characterEncoding=UTF-8"/>
                <property name="user" value="root"/>
                <property name="password" value="root"/>
                <property name="initialPoolSize" value="5"/>
                <property name="maxPoolSize" value="20"/>
                <property name="minPoolSize" value="5"/>
				
            dataSource>
