#Thrift连接池实现

##特性

• 1、支持服务器之间的负载均衡
  
• 2、每个服务器拥有一个独立的连接分区 所有的连接分区合并一起为整个连接池
  
• 3、连接池支持自动创建连接、管理超时连接、管理失效连接
  
• 4、支持服务器列表动态增加或者移除
  
• 5、支持自动调取ping方法(在thrift描述文件添加方法void ping(),)检测连接可用性
  
• 6、支持当服务不可用时自动将对应的服务器剔除连接池的功能
  
• 7、添加多服务接口支持

###示例 ####单服务示例 ThriftConnectionPoolConfig config = new ThriftConnectionPoolConfig(); config.setConnectTimeout(3000); config.setThriftProtocol(TProtocolType.BINARY); config.setClientClass(Example.Client.class); config.addThriftServer("127.0.0.1", 9119); config.setMaxConnectionPerServer(2); config.setMinConnectionPerServer(1); config.setIdleMaxAge(2, TimeUnit.SECONDS); config.setMaxConnectionAge(2); config.setLazyInit(false); try { ThriftConnectionPool<Example.Client> pool = new ThriftConnectionPool<Example.Client>(config); Example.Client client = pool.getConnection().getClient(); client.ping(); pool.close(); } catch (ThriftConnectionPoolException e) { e.printStackTrace(); } catch (TException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }

####多接口服务示例 ThriftConnectionPoolConfig config = new ThriftConnectionPoolConfig(ThriftServiceType.MULTIPLEXED_INTERFACE); config.setConnectTimeout(3000); config.setThriftProtocol(TProtocolType.BINARY); config.addThriftServer("127.0.0.1", 9119); config.addThriftClientClass("other", Other.Client.class); config.addThriftClientClass("example", Example.Client.class);

config.setMaxConnectionPerServer(2);
config.setMinConnectionPerServer(1);
config.setIdleMaxAge(2, TimeUnit.SECONDS);
config.setMaxConnectionAge(2);
config.setLazyInit(false);
config.setAcquireIncrement(2);
config.setAcquireRetryDelay(2000);

config.setAcquireRetryAttempts(1);
config.setMaxConnectionCreateFailedCount(1);
config.setConnectionTimeoutInMs(5000);

config.check();

ThriftConnectionPool<TServiceClient> pool = new ThriftConnectionPool<TServiceClient>(config);
ThriftConnection<TServiceClient> connection = pool.getConnection();
// example service
com.wmz7year.thrift.pool.example.Example.Client exampleServiceClient = connection.getClient("example",
		Example.Client.class);
exampleServiceClient.ping();

// other service
com.wmz7year.thrift.pool.example.Other.Client otherServiceClient = connection.getClient("other",
		Other.Client.class);
otherServiceClient.ping();
pool.close();

####接下来需要完善内容： 1、补充文档
2、补充性能测试
3、完善使用例子
4、操作重试机制?
