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");
 
     .......
  }
}
