mybatis+proxool 实现第三方数据库连接池
mybatis不直接支持第三方的数据库连接池，需要自己建DataSourceFactory。
用到的jar：mybatis-3.0.4.jar、proxool-0.9.1.jar、proxool-cglib.jar等。
ProxoolDataSourceFactory.java代码如下：
public class ProxoolDataSourceFactory implements DataSourceFactory {
protected ProxoolDataSource dataSource;
public ProxoolDataSourceFactory() {
this.dataSource = new ProxoolDataSource();
}
/*
* (non-Javadoc)
*
* @see org.apache.ibatis.datasource.DataSourceFactory#getDataSource()
*/
public DataSource getDataSource() {
return this.dataSource;
}
/*
* (non-Javadoc)
*
* @see
* org.apache.ibatis.datasource.DataSourceFactory#setProperties(java.util
* .Properties)
*/
public void setProperties(Properties properties) {
dataSource.setDriver(properties.getProperty("driver"));
dataSource.setDriverUrl(properties.getProperty("driverUrl"));
dataSource.setUser(properties.getProperty("user"));
dataSource.setPassword(properties.getProperty("password"));
dataSource.setAlias(properties.getProperty("alias"));
// 其他参数略
}
}
mybatis-config.xml配置文件片段：
<typeAliases><typeAlias type="com.lazylei.demo.datasource.proxool.ProxoolDataSourceFactory" alias="PROXOOL" /></typeAliases>
<environments default="db1">
<environment id="db1">
<transactionManager type="JDBC" />
<dataSource type="PROXOOL">
<property name="driver" value="${proxool.db1.driver}" />
<property name="driverUrl" value="${proxool.db1.driverUrl}" />
<property name="user" value="${proxool.db1.user}" />
<property name="password" value="${proxool.db1.password}" />
<property name="alias" value="${proxool.db1.alias}" />
</dataSource>
</environment>
<environment id="db2">
<transactionManager type="JDBC" />
<dataSource type="PROXOOL">
<property name="driver" value="${proxool.db2.driver}" />
<property name="driverUrl" value="${proxool.db2.driverUrl}" />
<property name="user" value="${proxool.db2.user}" />
<property name="password" value="${proxool.db2.password}" />
<property name="alias" value="${proxool.db2.alias}" />
</dataSource>
</environment>
</environments>
