Question

我在Spring项目中使用ActiveMQ时遇到问题。我正在尝试将ActiveMQ maven插件集成到我的项目中，以便在集成测试中使用它。在这里我的配置：

我遇到的问题是使用jetty命名空间。无法找到并下载架构：http://jetty.mortbay.org/jetty.xsd 这里是Apache ActiveMQ的链接： http://activemq.apache.org/complex-single-broker-configuration-stomp-only.html

此架构未指定任何位置。 ActiveMQ在没有模式位置的情况下启动，但如果我使用Eclipse中的模式验证程序，它会告诉我文件中有错误，无法找到模式位置。

我知道在哪里可以找到jetty元素的模式吗？

我也遇到了这个问题，我花了整整一个小时才找到解决方案。

基本上the example in the documentation已过时。

使用activemq-maven-plugin启用jetty所需的依赖关系如下：

 <dependency>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>jetty-xbean</artifactId>
    <version>6.1.25</version>
    <exclusions>
        <exclusion>
             <groupId>org.springframework</groupId>
             <artifactId>spring</artifactId>
        </exclusion>
    </exclusions>
 </dependency>
 <dependency>
    <groupId>org.eclipse.jetty.aggregate</groupId>
    <artifactId>jetty-all-server</artifactId>
    <version>7.6.7.v20120910</version>
</dependency>

以下是activemq-maven-plugin的完整配置：

<plugin>
    <groupId>org.apache.activemq.tooling</groupId>
    <artifactId>activemq-maven-plugin</artifactId>
    <version>5.8.0</version>
    <configuration>
        <configUri>${configUri}</configUri>
        <fork>false</fork>
        <systemProperties>
            <property>
                <name>javax.net.ssl.keyStorePassword</name>
                <value>password</value>
            </property>
            <property>
                <name>org.apache.activemq.default.directory.prefix</name>
                <value>./target/</value>
            </property>
        </systemProperties>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-spring</artifactId>
            <version>5.8.0</version>
        </dependency>
        <dependency>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>jetty-xbean</artifactId>
            <version>6.1.25</version>
            <exclusions>
                <exclusion>
                     <groupId>org.springframework</groupId>
                     <artifactId>spring</artifactId>
                </exclusion>
            </exclusions>
         </dependency>
         <dependency>
            <groupId>org.eclipse.jetty.aggregate</groupId>
            <artifactId>jetty-all-server</artifactId>
            <version>7.6.7.v20120910</version>
        </dependency>
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-leveldb-store</artifactId>
            <version>5.8.0</version>
        </dependency>
    </dependencies>
    <executions>
        <execution>
            <id>start-activemq</id>
            <goals>
                <goal>run</goal>
            </goals>
            <phase>pre-integration-test</phase>
        </execution>
    </executions>
</plugin>

然后启用jetty就足以将jetty配置文件导入activemq配置文件。

在撰写本文时（5.8.0），ActiveMQ最新版本中的文件$ {ACTIVEMQ_HOME} /conf/activemq.xml中提取了以下代码段：

<beans
          xmlns="http://www.springframework.org/schema/beans"
          xmlns:amq="http://activemq.apache.org/schema/core"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
          http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd">

    <!--
        The <broker> element is used to configure the ActiveMQ broker.
    -->
    <broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}">

       ...

    </broker>

    <!--
        Enable web consoles, REST and Ajax APIs and demos

        Take a look at ${ACTIVEMQ_HOME}/conf/jetty.xml for more details
    -->
    <import resource="jetty.xml"/>

</beans>
