【解决方案1】：

对于 Maven 用户，

如果你的应用是mavenized，那么去POM文件添加如下依赖：

 <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-all</artifactId>
        <version>5.14.5</version>
 </dependency>

对于 gradle 用户，

如果你的应用是gradlized的，那么去build.gradle添加如下依赖：

//https://mvnrepository.com/artifact/org.apache.activemq/activemq-all

编译组：'org.apache.activemq'，名称：'activemq-all'，版本：'5.14.5'

对于其他人，

如果你的应用没有经过maven化，那么

  1. 右键单击您的项目

  2. 点击Properties并在属性窗口中，

  3. 单击/选择Java Build Path 并选择标签Libraries 和

  4. 点击按钮Add external JARS.. 和

  5. 选择文件activemq-all-x.xx.x,jar

这将在 apache-activemq 文件夹的根文件夹中可用。
