MySQL 读写分离实例详解

MySQL 读写分离
MySQL读写分离又一好办法使用 com.mysql.jdbc.ReplicationDriver
在用过Amoeba 和 Cobar，还有dbware 等读写分离组件后，今天我的一个好朋友跟我讲，MySQL自身的也是可以读写分离的，因为他们提供了一个新的驱动，叫 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 slavesprops.put（"autoReconnect", "true"）; // We want to load balance between the slavesprops.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"）;....... }}
