C++ ActiveMQ实现通讯
C++ ActiveMQ实现通讯完整版
简介
该博客收到一些反应，说教程不够明细操作的时候怎么都不行，特今日（2017年8月29日17点）进行博客修改，并将新demo一起附上,建议看看博客下面的“需要注意的地方”后在来编译demo！
所需的关联lib,dll，还有新实例demo都在下面这个附件里面，我的demo是用的vs2008编辑器。
新附件下载地址（如失效请联系）：http://pan.baidu.com/s/1eS1pzkm
也可以直接参考下面的代码
编译的是时候需要导入activemq-cpp源码，可以去官网下载
http://activemq.apache.org/cms/download.html
activemq-cpp.lib activemq-cpp.dll也是需要编译的,嫌编译麻烦，可以直接使用附件里面编译好的
apr依赖下载地址：http://apr.apache.org/download.cgi
apr-1.6.2-win32-src.zip，apr-iconv-1.2.1-win32-src-r2.zip， apr-util-1.6.0-win32-src.zip
一共是三个，下载后需要编译出lib,dll ,嫌编译麻烦，可以直接使用附件里面编译好的
一.生产者头文件定义
#include "stdafx.h"
#include 二.生产者实现
#include "stdafx.h"
#include "SimpleProducer.h"
#include 三.消费者头文件定义
#include 四.消费者实现
// 4、SimpleAsyncConsumer.cpp
#include "stdafx.h"
#include "SimpleAsyncConsumer.h"
SimpleAsyncConsumer::~SimpleAsyncConsumer()
{
cleanup();
}
void SimpleAsyncConsumer::close()
{
cleanup();
}
void SimpleAsyncConsumer::start(const std::string& brokerURI, const std::string& destURI, bool useTopic, bool clientAck )
{
this->connection = NULL;
this->session = NULL;
this->destination = NULL;
this->consumer = NULL;
this->useTopic = useTopic;
this->brokerURI = brokerURI;
this->destURI = destURI;
this->clientAck = clientAck;
runConsumer();
}
void SimpleAsyncConsumer::runConsumer()
{
try {
// Create a ConnectionFactory
//ActiveMQConnectionFactory* connectionFactory = new ActiveMQConnectionFactory( brokerURI );
ActiveMQConnectionFactory* connectionFactory = new ActiveMQConnectionFactory("tcp://127.0.0.1:61616?transport.useAsyncSend=true&maxReconnectDelay=10000");
//connection = connectionFactory->createConnection("userName","pwd");
connection = connectionFactory->createConnection();
//delete connectionFactory;
ActiveMQConnection* amqConnection = dynamic_cast( connection );
if( amqConnection != NULL ) {
amqConnection->addTransportListener( this );
}
connection->start();
connection->setExceptionListener(this);
// Create a Session
if( clientAck ) {
session = connection->createSession( Session::CLIENT_ACKNOWLEDGE );
} else {
session = connection->createSession( Session::AUTO_ACKNOWLEDGE );
}
// Create the destination (Topic or Queue)
if( useTopic ) {
destination = session->createTopic( destURI );
} else {
destination = session->createQueue( destURI );
}
// Create a MessageConsumer from the Session to the Topic or Queue
consumer = session->createConsumer( destination );
consumer->setMessageListener( this );
} catch (CMSException& e) {
printf("SimpleAsyncConsumer createConnection faill!");
e.printStackTrace();
}
}
// Called from the consumer since this class is a registered MessageListener.
void SimpleAsyncConsumer::onMessage( const Message* message )
{
static int count = 0;
try{
count++;
const TextMessage* txtMessage =
dynamic_cast< const TextMessage* >( message );
string text;
if( txtMessage != NULL ) {
text = txtMessage->getText();
} else {
text = "NOT A BYTE SMESSAGE!";
}
if( clientAck ) {
message->acknowledge();
}
printf( "收到字符串MSG: %s\n", text.c_str() );
} catch (CMSException& e) {

e.printStackTrace();
}
}
void SimpleAsyncConsumer::onException( const CMSException& ex AMQCPP_UNUSED )
{
printf("CMS Exception occurred. Shutting down client.\n");
exit(1);
}
void SimpleAsyncConsumer::transportInterrupted()
{
std::cout << "The Connection's Transport has been Interrupted." << std::endl;
}
void SimpleAsyncConsumer::transportResumed()
{
std::cout << "The Connection's Transport has been Restored." << std::endl;
}
void SimpleAsyncConsumer::cleanup(){
//*************************************************
// Always close destination, consumers and producers before
// you destroy their sessions and connection.
//*************************************************
// Destroy resources.
try{
if( destination != NULL ) delete destination;
}catch (CMSException& e) {
}
destination = NULL;
try{
if( consumer != NULL ) delete consumer;
}catch (CMSException& e) {
}
consumer = NULL;
// Close open resources.
try{
if( session != NULL ) session->close();
if( connection != NULL ) connection->close();
}catch (CMSException& e) {
}
// Now Destroy them
try{
if( session != NULL ) delete session;
}catch (CMSException& e) {
}
session = NULL;
try{
if( connection != NULL ) delete connection;
}catch (CMSException& e) {
}
connection = NULL;
} 五.主函数调用示例
// ActiveMQDemo.cpp : 定义控制台应用程序的入口点。
//
#include "stdafx.h"
#include "SimpleProducer.h"
#include "SimpleAsyncConsumer.h"
SimpleProducer g_SimpleProducer;
SimpleAsyncConsumer g_SimpleAsyncConsumer;
int _tmain(int argc, _TCHAR* argv[])
{
activemq::library::ActiveMQCPP::initializeLibrary();
std::string brokerURI;
std::string destURI;
bool useTopics;
bool clientAck;
//brokerURI ="tcp://127.0.0.1:61616?transport.useAsyncSend=true&maxReconnectDelay=10000";
brokerURI ="failover:(tcp://localhost:61616)";
useTopics = false;
unsigned int numMessages = 99999999;
clientAck = false;
//destURI = "Queue.HQ.Local";
//destURI = "Queue.HQ";
//g_SimpleProducer.start( brokerURI, numMessages, destURI, useTopics ,clientAck);
destURI = "Queue.test";
g_SimpleProducer.start( brokerURI, numMessages, destURI, useTopics ,clientAck);
g_SimpleProducer.sendTxtMsg("test");
std::string brokerURIs;
std::string destURIs;
bool useTopicss;
bool clientAcks;
brokerURIs = "failover:(tcp://127.0.0.1:61616)";
useTopicss = false;
unsigned int numMessagess = 2000;
destURIs = "Queue.test";
clientAcks = false;
g_SimpleAsyncConsumer.start(brokerURIs, destURIs, useTopicss, clientAcks);
g_SimpleAsyncConsumer.runConsumer();
printf("发送字符串数据ok");
getchar();
activemq::library::ActiveMQCPP::shutdownLibrary();
return 0;
}
.这些地方是需要注意的
apr因为消费者需要,单独在C/C++ --->常规中的附加包含目录 引入，另外还有activemq-cpp的源码也是
D:\project\projectpc\work\activemq-cpp-library-3.4.0\src\main （换成你自己的目录放到附加包含目录）
下图是那些编译好的lib dll附加库目录 属性配置
这是将那些编译好的lib要加入到链接器 -> 输入->附加依赖项 中
activemq-cpp.lib apr-1.lib
apriconv-1.lib
aprutil-1.lib
cppunit.lib
libapr-1.lib
libapriconv-1.lib
libaprutil-1.lib
xml.lib
最后需要特别注意的是，需要把编译生成的各种dll放到exe执行目录下，这样执行exe的时候才能调用到那些内库，如下图
最最后要说明的当然是在运行的时候要运行activemq服务，先前就有同学说，他都配置好了，也能正常编译就是发不了消息也收不到消息，然后总找不到原因，希望同学细心点啊。
最后贴上demo运行示例图，收工!
