我试图通过在ActiveMQ文档后面构建.war文件来向Artemis REST接口添加REST接口。生成.war文件后,我将其移动到/opt/artemis/apache-artemis-2.13.0/web/目录中,并启动ActiveMQ Artemis。
启动ActiveMQ Artemis时,我将得到下一个异常:
WARN [org.eclipse.jetty.webapp.WebAppContext] Failed startup of context o.e.j.w.WebAppContext@4cb702ce{/artemis-rest,file:///var/lib/test-broker/tmp/jetty-0_0_0_0-8161-artemis-rest_war-_artemis-rest-any-15304647904836420970.dir/webapp/,UNAVAILABLE}{/opt/artemis/apache-artemis-2.13.0/web/artemis-rest.war}: java.lang.RuntimeException: You must install RESTEasy as a Bootstrap Listener and it must be listed before this class

SERVLET: -我没有安装RESTeasy,因为我找不出如何安装,所以我下载了RESTeasy jaxrs版本3.13.0.Final的jar文件,并将其放在WEB-INF/lib目录中,并在pom.xml中包含了它的依赖项。
让我向你展示我的配置:

如果您知道向ActiveMQ Artemis添加REST接口的其他方法,请通知我。

不幸的是,ActiveMQ Artemis的其余文档已经有一段时间没有被验证或更新了。
您可以在war文件中获取所需的一切,并使用此pom.xml排除大部分不需要的内容。

<acceptors>
...
<acceptor name="invm">vm://0</acceptor>
</acceptors>此外,如果像这样构造项目,则可以自动包含REST配置XML:
|-- pom.xml
`-- src
`-- main
`-- webapp
`-- WEB-INF
`-- web.xml
`-- resources
`-- rest.xml然后,您可以在web.xml中引用它,如下所示:
<context-param>
<param-name>rest.messaging.config.file</param-name>
<param-value>rest.xml</param-value>
</context-param>通常,出于两个主要原因,我建议不要使用ActiveMQ Artemis接口:
我建议您使用STOMP来代替ActiveMQ Artemis接口。
