示例1: getDatasourceByGroupNode
import com.taobao.tddl.executor.spi.IGroupExecutor; //导入方法依赖的package包/类
public DataSource getDatasourceByGroupNode(TopologyHandler topology, String groupNode) {
if ("undecided".equals(groupNode)) {
return null;
}
IGroupExecutor matrixExecutor = topology.get(groupNode);
if (matrixExecutor == null) return null;
/*
* 这里做个hack吧。 原因是在构造topologic的时候,默认全部使用mysql作为type了。
* 这样就造成所有的Datasource都是由RemotingExecutor
* com.taobao.ustore.jdbc.mysql.My_Reponsitory.buildRemoting(Group
* group) 创建的,type都是mysql.
* 但实际上这里的type需要根据实际的DataSource来决定是个oracle还是个mysql.
* 如果是oracle那么type需要改成oracle..
