本文介绍了在JBoss AS7中部署MBean的具体步骤与注意事项，包括所需类的实现方式变化及jboss-service.xml配置文件的正确写法，并提供了一个具体的配置示例。

为什么80%的码农都做不了架构师？>>>

在 JBoss AS 7 之前的版本中使用 SAR 时，你需要一个 extends 了 org.jboss.system.ServiceMBeanSupport 并 implements org.jboss.system.ServiceMBean 的类。但在 JBoss AS 7 中，这两者都不存在了。

在 JBoss AS 7 中实现一个 MBean 你只需要一个实现了自定义接口的类。jboss-service.xml 中的配置和过去相同，但是必须制定 XML Schema，否则会有如下的异常：

<!-- lang: shell -->

JBoss AS 7 中 jboss-service.xml 配置示例：

<!-- lang: xml -->
<?xml version="1.0" encoding="UTF-8"?>
<server xmlns="urn:jboss:service:7.0"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="urn:jboss:service:7.0 jboss-service_7_0.xsd">
    <mbean code="custom.mbean.MyServerMonitor" name="service.server.monitor:service=MyMonitor">
        <attribute name="Frequency">5000</attribute>
    </mbean>
</server>
