<chapter id="wildcard-routing">
<title>使用通配符实现消息路由</title>
<para>HornetQ支持使用带通配符的地址对消息路由。</para>
<para>例如,当创建一个队列时使用了地址<literal>queue.news.#</literal>,那么它就能接收
所有和这个地址通配符相配的每一个地址的消息。这样的地址如 <literal
>queue.news.europe</literal><literal>queue.news.usa</literal><literal
>queue.news.usa.sport</literal>等。这样一个消息接收者可以接收<literal>一组</literal>相关
的地址的消息,而不是只能指定一个具体的地址。</para>
<note>
<para>用JMS的术语来说这个功能就是允许创建“话题组”topic hierarchy</para>
</note>
<para>要使用本功能需要将<literal>wild-card-routing-enabled</literal>属性设置为<literal>true</literal>
这个属性在 <literal>hornetq-configuration.xml</literal> 文件中。默认值是<literal>true</literal></para>
<para>关于通配符的语法参见<xref
linkend="wildcard-syntax" /> 章及 <xref
linkend="topic-hierarchy-example" /></para>
