• ActiveMQ之ActiveMQ-CPP安装及测试


      在介绍ActiveMQ-CP之前,先介绍下CMS(C++ Messaging Service),CMS是C++程序与消息中间件进行通信的一种标准接口,可以通过CMS接口与类似ActiveMQ这样的消息中间件进行通信,它能够让C++程序与消息中间件之间的交互更加优雅和便捷。

      ActiceMQ-CPP是CMS的一种实现,是一个能够与ActiveMQ进行通信的C++客户端库,ActiveMQ-CPP的架构设计能够支持可插拨的传输协议和消息封装格式,并且支持客户端容量,能够与ActiveMQ高效和便捷地进行通信,并且提供一系列跨平台的类Java API的特性,如多线程处理、I/O、sockets等。

    1. ActiveMQ-CPP安装

      ActiveMQ-CPP的编译依赖libuuid、apr、apr-util、apr-iconv、openssl几个库,如果需要跑CppUnit编写的test,还依赖于cppunit,因此在安装使用ActiveMQ-CPP之前,至少得安装libuuid、apr、apr-util、apr-iconv、openssl几个库。

    1.1 安装libuuid

      util-linux-ng在2.15.1版本以后,已经将libuuid作为一部分包含进来,因此,只需要安装util-linux-ng即可

    (1)查询系统是否安装util-linux-ng

      

    (2)若没有安装的话安装正常流程:

      下载

      解压

      指定目录安装:./configure --without-ncurses --prefix=/usr/local/util-linux-ng

      编译安装:make

      sudo make install

    1.2 安装apr

    (1)下载apr:http://archive.apache.org/dist/apr/

    (2)解压

      tar -xf apr-1.4.8.tar.gz

    (3)配置apr源码,并指定路径

      ./configure --prefix=/usr/local/apr

    (4)编译安装

      make

      sudo make install

    1.3 安装apr-iconv

    (1)下载apr-iconv:http://archive.apache.org/dist/apr/

    (2)解压

      tar -xf apr-iconv-1.2.1.tar.gz

    (3)配置源码,指定路径/usr/local/apr-iconv,并且指定apr的安装

      ./configure --prefix=/usr/local/apr-iconv --with-apr=/usr/local/apr

    (4)编译安装

      make

      sudo make install

    1.4 安装openssl

      在安装openssl的过程中发现系统中已经安装了openssl,查找安装目录:

      

      lib的安装目录很重要,后面安装ActiveMQ-CPP时需要

      若系统中没有安装openssl,则按照正常流程安装

    (1)下载:openssl-1.0.1e.tar.gz

    (2)解压:tar -xf openssl-1.0.1e.tar.gz

    (3)配置源码,并指定路径

      ./configure --prefix=/usr/local/openssl

    (4)编译安装

      make

      sudo make install

    1.5 安装ActiveMQ-CPP

    (1)下载:http://activemq.apache.org/cms/activemq-cpp-381-release.html

    (2)解压

      tar -xf activemq-cpp-library-3.8.1-src.tar.gz

    (3)配置源码,指定apr、openssl安装路径,以及ActiveMQ-CPP将要安装的路径

      ./configure --prefix=/usr/local/activemq-cpp --with-apr=/usr/local/apr/ --with-openssl=/usr/local/openssl

    (4)编译安装

      make

      sudo make install

    2. CMS应用程序接口

    (1)ConnectionFactory

      用户用来创建到JMS提供者的连接的被管对象。JMS客户通过可移植的接口访问连接,这样当下层的实现改变时,代码不需要进行修改。 管理员

    在JNDI名字空间中配置连接工厂,这样,JMS客户才能够查找到它们。根据消息类型的不同,用户将使用队列连接工厂,或者主题连接工厂。

    #ifndef _CMS_CONNECTIONFACTORY_H_
    #define _CMS_CONNECTIONFACTORY_H_
    
    #include <cms/Config.h>
    #include <cms/CMSException.h>
    
    #include <string>
    
    namespace cms {
    
        class Connection;
        class ExceptionListener;
        class MessageTransformer;
    
        class CMS_API ConnectionFactory {
        public:
            virtual ~ConnectionFactory();
            virtual cms::Connection* createConnection() = 0;
            virtual cms::Connection* createConnection(const std::string& username, const std::string& password) = 0;
            virtual cms::Connection* createConnection(const std::string& username, const std::string& password, const std::string& clientId) = 0;
            virtual void setExceptionListener(cms::ExceptionListener* listener) = 0;
            virtual cms::ExceptionListener* getExceptionListener() const = 0;
            virtual void setMessageTransformer(cms::MessageTransformer* transformer) = 0;
            virtual cms::MessageTransformer* getMessageTransformer() const = 0;
    
        public:
            static cms::ConnectionFactory* createCMSConnectionFactory(const std::string& brokerURI);
    
        };
    
    }
    #endif /*_CMS_CONNECTIONFACTORY_H_*/

    (2)Connection

      连接代表了应用程序和消息服务器之间的通信链路。在获得了连接工厂后,就可以创建一个与JMS提供者的连接。根据不同的连接类型,连接允许用户创建会话,以发送和接收队列和主题到目标。

    #ifndef _CMS_CONNECTION_H_
    #define _CMS_CONNECTION_H_
    
    #include <cms/Config.h>
    #include <cms/Startable.h>
    #include <cms/Stoppable.h>
    #include <cms/Closeable.h>
    #include <cms/Session.h>
    #include <cms/ConnectionMetaData.h>
    
    namespace cms {
        class ExceptionListener;
        class MessageTransformer;
    
        class CMS_API Connection : public Startable, public Stoppable, public Closeable {
        public:
    
            virtual ~Connection();
            virtual void close() = 0;
            virtual const ConnectionMetaData* getMetaData() const = 0;
            virtual Session* createSession() = 0;
            virtual Session* createSession(Session::AcknowledgeMode ackMode) = 0;
            virtual std::string getClientID() const = 0;
            virtual void setClientID(const std::string& clientID) = 0;
            virtual ExceptionListener* getExceptionListener() const = 0;
            virtual void setExceptionListener(ExceptionListener* listener) = 0;
            virtual void setMessageTransformer(cms::MessageTransformer* transformer) = 0;
            virtual cms::MessageTransformer* getMessageTransformer() const = 0;
        };
    }
    #endif /*_CMS_CONNECTION_H_*/

    (3)Session

      表示一个单线程的上下文,用于发送和接收消息。由于会话是单线程的,所以消息是连续的,就是说消息是按照发送的顺序一个一个接收的。会话的好处是它支持事务。如果用户选择了事务支持,会话上下文将保存一组消息,直到事务被提交才发送这些消息。在提交事务之前,用户可以使用回滚操作取消这些消息。一个会话允许用户创建消息生产者来发送消息,创建消息消费者来接收消息。

    namespace cms {
    
        class MessageTransformer;
        class CMS_API Session : public Closeable, public Startable, public Stoppable {
        public:
            enum AcknowledgeMode {
                AUTO_ACKNOWLEDGE,
                // 使用此确认模式,会话自动进行
                DUPS_OK_ACKNOWLEDGE,
                CLIENT_ACKNOWLEDGE,
                SESSION_TRANSACTED,
                INDIVIDUAL_ACKNOWLEDGE
            };
    
        public:
            virtual ~Session();
            virtual void close() = 0;
            virtual void commit() = 0;
            virtual void rollback() = 0;
            virtual void recover() = 0;
            virtual MessageConsumer* createConsumer(const Destination* destination) = 0;
            virtual MessageConsumer* createConsumer(const Destination* destination, const std::string& selector) = 0;
            virtual MessageConsumer* createConsumer(const Destination* destination, const std::string& selector, bool noLocal) = 0;
            virtual MessageConsumer* createDurableConsumer(const Topic* destination, const std::string& name, const std::string& selector, bool noLocal = false) = 0;
            virtual MessageProducer* createProducer(const Destination* destination = NULL) = 0;
            virtual QueueBrowser* createBrowser(const cms::Queue* queue) = 0;
            virtual QueueBrowser* createBrowser(const cms::Queue* queue, const std::string& selector) = 0;
            virtual Queue* createQueue(const std::string& queueName) = 0;
            virtual Topic* createTopic(const std::string& topicName) = 0;
            virtual TemporaryQueue* createTemporaryQueue() = 0;
            virtual TemporaryTopic* createTemporaryTopic() = 0;
            virtual Message* createMessage() = 0;
            virtual BytesMessage* createBytesMessage() = 0;
            virtual BytesMessage* createBytesMessage(const unsigned char* bytes, int bytesSize) = 0;
            virtual StreamMessage* createStreamMessage() = 0;
            virtual TextMessage* createTextMessage() = 0;
            virtual TextMessage* createTextMessage(const std::string& text) = 0;
            virtual MapMessage* createMapMessage() = 0;
            virtual AcknowledgeMode getAcknowledgeMode() const = 0;
            virtual bool isTransacted() const = 0;
            virtual void unsubscribe(const std::string& name) = 0;
            virtual void setMessageTransformer(cms::MessageTransformer* transformer) = 0;
            virtual cms::MessageTransformer* getMessageTransformer() const = 0;
        };
    }
    #endif /*_CMS_SESSION_H_*/

    (4)Destination

      目标是一个包装了消息目标标识符的被管对象,消息目标是指消息发布和接收的地点,或者是队列,或者是主题。JMS管理员创建这些对象,然后用户通过JNDI发现它们。和连接工厂一样,管理员可以创建两种类型的目标,点对点模型的队列,以及发布者/订阅者模型的主题。

    namespace cms {
        class CMS_API Destination {
        public:
            enum DestinationType {
                TOPIC,
                QUEUE,
                TEMPORARY_TOPIC,
                TEMPORARY_QUEUE
            };
    
        public:
            virtual ~Destination();
            virtual DestinationType getDestinationType() const = 0;
            virtual cms::Destination* clone() const = 0;
            virtual void copy(const cms::Destination& source) = 0;
            virtual bool equals(const cms::Destination& other) const = 0;
            virtual const CMSProperties& getCMSProperties() const = 0;
        };
    }
    class CMS_API Queue : public Destination
    class CMS_API Topic : public Destination

    (5)MessageConsumer

      由会话创建的对象,用于接收发送到目标的消息。消费者可以同步地(阻塞模式),或异步(非阻塞)接收队列和主题类型的消息。

    namespace cms {
    
        class MessageTransformer;
        class CMS_API MessageConsumer : public Closeable, public Startable, public Stoppable {
        public:
            virtual ~MessageConsumer();
            virtual Message* receive() = 0;
            virtual Message* receive(int millisecs) = 0;
            virtual Message* receiveNoWait() = 0;
            virtual void setMessageListener(MessageListener* listener) = 0;
            virtual MessageListener* getMessageListener() const = 0;
            virtual std::string getMessageSelector() const = 0;
            virtual void setMessageTransformer(cms::MessageTransformer* transformer) = 0;
            virtual cms::MessageTransformer* getMessageTransformer() const = 0;
            virtual void setMessageAvailableListener(cms::MessageAvailableListener* listener) = 0;
            virtual cms::MessageAvailableListener* getMessageAvailableListener() const = 0;
        };
    }

    (6)MessageProducer

      由会话创建的对象,用于发送消息到目标。用户可以创建某个目标的发送者,也可以创建一个通用的发送者,在发送消息时指定目标。

    namespace cms {
        class MessageTransformer;
        class CMS_API MessageProducer : public Closeable {
        public:
            virtual ~MessageProducer();
            virtual void send(Message* message) = 0;
            virtual void send(Message* message, AsyncCallback* onComplete) = 0;
            virtual void send(Message* message, int deliveryMode, int priority, long long timeToLive) = 0;
            virtual void send(Message* message, int deliveryMode, int priority,
                              long long timeToLive, AsyncCallback* onComplete) = 0;
            virtual void send(const Destination* destination, Message* message) = 0;
            virtual void send(const Destination* destination, Message* message, AsyncCallback* onComplete) = 0;
            virtual void send(const Destination* destination, Message* message,
                              int deliveryMode, int priority, long long timeToLive) = 0;
            virtual void send(const Destination* destination, Message* message, int deliveryMode,
                              int priority, long long timeToLive, AsyncCallback* onComplete) = 0;
            virtual void setDeliveryMode(int mode) = 0;
            virtual int getDeliveryMode() const = 0;
            virtual void setDisableMessageID(bool value) = 0;
            virtual bool getDisableMessageID() const = 0;
            virtual void setDisableMessageTimeStamp(bool value) = 0;
            virtual bool getDisableMessageTimeStamp() const = 0;
            virtual void setPriority(int priority) = 0;
            virtual int getPriority() const = 0;
            virtual void setTimeToLive(long long time) = 0;
            virtual long long getTimeToLive() const = 0;
            virtual void setMessageTransformer(cms::MessageTransformer* transformer) = 0;
            virtual cms::MessageTransformer* getMessageTransformer() const = 0;
        };
    }

    (7)Message

      是在消费者和生产者之间传送的对象,也就是说从一个应用程序创送到另一个应用程序。一个消息有三个主要部分:消息头(必须):包含用于识别和为消息寻找路由的操作设置。一组消息属性(可选):包含额外的属性,支持其他提供者和用户的兼容。可以创建定制的字段和过滤器(消息选择器)。一个消息体(可选):允许用户创建五种类型的消息(文本消息,映射消息,字节消息,流消息和对象消息)。消息接口非常灵活,并提供了许多方式来定制消息的内容。

    namespace cms {
        class CMS_API Message {
        public:
            static const int DEFAULT_DELIVERY_MODE;
            static const int DEFAULT_MSG_PRIORITY;
            static const long long DEFAULT_TIME_TO_LIVE;
    
            enum ValueType {
                NULL_TYPE = 0,
                BOOLEAN_TYPE = 1,
                BYTE_TYPE = 2,
                CHAR_TYPE = 3,
                SHORT_TYPE = 4,
                INTEGER_TYPE = 5,
                LONG_TYPE = 6,
                DOUBLE_TYPE = 7,
                FLOAT_TYPE = 8,
                STRING_TYPE = 9,
                BYTE_ARRAY_TYPE = 10,
                UNKNOWN_TYPE = 11
            };
    
        public:
