mybatis 自定义 datasource

• 实现 org.apache.ibatis.datasource.DataSourceFactory 接口

import com.alibaba.druid.pool.DruidDataSource;
import org.apache.ibatis.datasource.DataSourceFactory;
import javax.sql.DataSource;
import java.util.Properties;

public class MyDataSource implements DataSourceFactory {
    private final DruidDataSource dataSource = new DruidDataSource();
    @Override
    public void setProperties(Properties props) {
        dataSource.configFromPropety(props);
    }
    @Override
    public DataSource getDataSource() {
        return dataSource;
    }
}

• 修改 mybatis 配置文件

        "http://mybatis.org/dtd/mybatis-3-config.dtd">
