opengauss数据库怎么通过JDBC设置主从库啊，网上的资源都好少，我这样写对吗？求各位帮助一下。
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClassName" value="org.postgresql.Driver" />
<property name="urL" value="jdbc:postgresql://195.220.11.10:2600,195.220.11.11:2600/cuser" /›
<property name="username" value="${cspdbUsername}" /›
<property name="password" value="${encry_cspdbpassword}" />
</bean>
你这个配置方式只是全连吧，开启主从模式要使用targetServerType参数，可以看一下官网解释：
targetServerType = {any, master, slave, preferSlave}
any表示连接到任意节点
preferSlave表示优先连接到slave节点
master或slave表示连接到master或slave节点。
案例：
For example an application can create two connection pools.
One data source is for writes, another for reads.
The write pool limits connections only to master node:
jdbc:postgresql://node1,node2,node3/accounting?targetServerType=master .
And read pool balances connections between slaves nodes, but allows connections also to master if no slaves are available:
jdbc:postgresql://node1,node2,node3/accounting?targetServerType=preferSlave&loadBalanceHosts=true
