问题描述
我正在尝试根据Artemis REST interface文档通过使用Maven构建.war文件来向ActiveMQ Artemis添加REST接口。
生成.war文件后,将其移至/opt/artemis/apache-artemis-2.13.0/web/
目录中并启动ActiveMQ Artemis。
启动ActiveMQ Artemis时出现下一个异常:
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
at org.apache.activemq.artemis.rest.integration.RestMessagingBootstrapListener.contextInitialized(RestMessagingBootstrapListener.java:39) [artemis-rest-2.13.0.jar:2.13.0]
此外,在HTTP请求http://192.168.0.50:8161/artemis-rest/queues/test
上获得503:
HTTP ERROR 503 Service Unavailable
URI: /artemis-rest/queues/test
STATUS: 503
MESSAGE: Service Unavailable
SERVLET: -
我没有安装RESTeasy,因为找不到方法,因此我下载了RESTeasy jaxrs版本3.13.0.jar的jar文件,并将其放在WEB-INF/lib
目录中,还包括依赖项在pom.xml
中实现。
让我告诉我我的配置:

如果需要,我还可以附加broker.xml
,jolokia-access.xml
和bootstrap.xml
文件,但对我来说似乎可以。我发现了有关此here的较旧问题,但这无助于解决这个问题。
如果您知道将REST接口添加到ActiveMQ Artemis的其他方法,请通知我。
解决方法
不幸的是,ActiveMQ Artemis的REST文档尚未经过验证或更新。
您可以在战争文件中获得所需的一切,并使用此pom.xml
排除大部分不需要的内容:
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

确保将虚拟机内接收器添加到您的broker.xml
中,例如:
<acceptors>
...
<acceptor name="invm">vm://0</acceptor>
</acceptors>
此外,如果您像这样构造项目,则可以自动包括REST配置XML:
|-- pom.xml
`-- src
`-- main
`-- webapp
`-- WEB-INF
`-- web.xml
`-- resources
`-- rest.xml
然后您可以像这样在web.xml
中引用它:
<context-param>
<param-name>rest.messaging.config.file</param-name>
<param-value>rest.xml</param-value>
</context-param>
一般来说,我建议使用ActiveMQ Artemis REST接口反对,主要有两个原因:
- 您的代码不会是可移植的,因为ActiveMQ Artemis REST接口是自定义(即未标准化)接口。
- STOMP协议无处不在,简单,标准化,并且可以在几乎可以使用REST的每种情况和环境中使用。
我建议您使用STOMP代替ActiveMQ Artemis REST接口。
