Windows下ActiveMQ的安装和简单使用

1. 官网下载ActiveMQ包，官网地址：Index of /dist/activemq

这里讲述的是apache-activemq-5.16.4这个版本，版本请勿随意使用，其与JDK有相互依赖关系，如下图：

2. 解压使用

2.1 将下载好的包解压到本地磁盘：

2.2 启动并访问。进入bin文件夹，双击打开“activemq.bat”。

如遇到打开“activemq.bat”黑框一闪而过时，请用命令方式启动。启动命令：

activemq-admin.bat start

浏览器访问：http://127.0.0.1:8161/，用户名和密码都是admin

3. 依赖引入

pom.xml增加相关依赖

        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-spring</artifactId>
            <version>5.16.4</version>
        </dependency>

4. 相关代码

Constant.java

/**

    public static String USER = "admin";

    BYTES("byte", "字节信息");

    public String key;

    public String value;

    /**

5. 测试代码

TestReceive.java

public class TestReceive {

    public static void main(String[] args) throws Exception {
        new MqAccept().startReceiveMessage();
    }

}

TestSend.java

public class TestSend {

    public static void main(String[] args) throws Exception {
        MQSendMsg.sendMsg(MsgTypeEnum.TEXT, "这是测试哈123...");
    }

}

测试发送接收功能
