MySQL 读写分离 使用驱动com.mysql.jdbc.ReplicationDriver

说明文档：http://dev.mysql.com/doc/refman/5.1/en/connector-j-reference-replication-connection.html

代码例子：

 import java.sql.Connection;
 import java.sql.ResultSet;
 import java.util.Properties;

 import com.mysql.jdbc.ReplicationDriver;

 public class ReplicationDriverDemo {

   public static void main(String[] args) throws Exception {
     ReplicationDriver driver = new ReplicationDriver();

     Properties props = new Properties();

     // We want this for failover on the slaves
     props.put("autoReconnect", "true");

     // We want to load balance between the slaves
     props.put("roundRobinLoadBalance", "true");

     props.put("user", "foo");
     props.put("password", "bar");

     //
     // Looks like a normal MySQL JDBC url, with a
     // comma-separated list of hosts, the first
     // being the 'master', the rest being any number
     // of slaves that the driver will load balance against
     //

     Connection conn =
         driver.connect("jdbc:mysql:replication://master,slave1,slave2,slave3/test",
             props);

     //
     // Perform read/write work on the master
     // by setting the read-only flag to "false"
     //

     conn.setReadOnly(false);
     conn.setAutoCommit(false);
     conn.createStatement().executeUpdate("UPDATE some_table ....");
     conn.commit();

     //
     // Now, do a query from a slave, the driver automatically picks one
     // from the list
     //

     conn.setReadOnly(true);

     ResultSet rs =
       conn.createStatement().executeQuery("SELECT a,b FROM alt_table");

      .......
   }
 }
