Mybatis整合Druid和H2嵌入式数据库

Mybatis整合Druid和H2嵌入式数据库

Mybatis的DataSource和Druid的DataSource不兼容，所以需要一个代理

package h2test;

import java.util.Properties;

import javax.sql.DataSource;

import org.apache.ibatis.datasource.DataSourceFactory;

public class DruidDataSourceFactory implements DataSourceFactory {
	private DataSource dataSource;

	@Override
	public DataSource getDataSource() {
		return this.dataSource;
	}

	@Override
	public void setProperties(final Properties props) {
		try {
			this.dataSource = com.alibaba.druid.pool.DruidDataSourceFactory.createDataSource(props);
		} catch (final RuntimeException e) {
			throw e;
		} catch (final Exception e) {
			throw new RuntimeException("init datasource error", e);
		}
	}
}
