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?
