本文介绍了如何使用C++ POCO库中的Connector模式来实现TCP客户端的服务初始化和行为分离，强调了在服务初始化和执行过程中处理连接断开的重连功能。通过SocketConnectorTest.h和SocketConnectorTest.cpp文件展示了具体的代码实现。

1.说明

　　使用poco net库中connector类（基于Connector Pattern思想），将服务初始化和服务行为分离，对Connector进行简单重构，编写ServiceHandler实现简单业务。主要解决：
　　1）服务初始化时，连接断开的重连。
　　2）执行服务业务行为时，连接断开的重连。

2.代码

SocketConnectorTest.h

#ifndef Net_SocketConnectorTest_INCLUDED
#define Net_SocketConnectorTest_INCLUDED


#include "Poco/Net/Net.h"
#include "Poco/Net/SocketNotification.h"
#include "Poco/Net/SocketAddress.h"
#include "Poco/Net/StreamSocket.h"
#include "Poco/Observer.h"


namespace Poco {
namespace Net {


template <class ServiceHandler>
class SocketConnector
{
public:
    explicit SocketConnector(SocketAddress& address):
        _pReactor(0)
    {
        _socket.connectNB(address);
    }

    SocketConnector(SocketAddress& address, SocketReactor& reactor):
        _pReactor(0)
    {
        _socket.connectNB(address);
        registerConnector(reactor);
    }

    virtual ~SocketConnector()
    {
        try
        {
            unregisterConnector();
        }
        catch (...)
        {
            poco_unexpected();
        }
    }

    virtual void registerConnector(SocketReactor& reactor)
    {
        _pReactor = &reactor;
        _pReactor->addEventHandler(_socket, Poco::Observer<SocketConnector, ReadableNotification>(*this, &SocketConnector::onReadable));
        _pReactor->addEventHandler(_socket, Poco::Observer<SocketConnector, WritableNotification>(*this, &SocketConnector::onWritable)
