我正在我的项目中尝试 Spring + JMX bean 配置。我是 JMX 技术的新手。我需要在托管 bean 中实现代理接口方式。尝试时，我收到以下提到的错误。

谁能指导我？我正在尝试在 tomcat 中部署我的战争。在启动时应用程序的上下文初始化中，我收到InvalidInvocationException

界面

package my.pjt.test.location;

public interface AppResourceLocationMBean {

    String getLocation();

    void setLocation(String location);
}

实现类

package my.pjt.test.location;

public class AppResourceLocation implements AppResourceLocationMBean {

    private volatile String location = "classpath:**/app-resource/**/";

    @Override public String getLocation() {
        return location;
    }

    @Override public void setLocation(String location) {
        this.location = location;
    }
}

在 AppLoader 中使用

package my.pjt.test.location;

public class AppLoader {

    private volatile AppResourceLocationMBean appLocationMBean;

     public void init() throws Exception {
        ...........
        String appLocation = this.appLocationMBean.getLocation();
        ..........  
    }
}

编辑：我仍然面临问题。我在https://github.com/appu-86/JMX-Test创建了一个示例项目。任何人都可以帮助/提示我示例项目中代理接口问题的原因吗？

尝试使用您的样品；当我throws OperationException按照我的建议添加时，我得到...

Caused by: javax.management.InstanceNotFoundException: test:name=appLocationConfiguration,type=SpringAppLocationConfiguration,context=pjt001

这个评论毫无意义：

<!-- Enabling below bean and disabling the above bean worked for me. But need a proxy interface solution. -->

代理是真正 MBean 的代理，而不是替代它 - MBean 必须存在于服务器中。

没有这样的 MBean "test:name=appLocationConfiguration,type=SpringAppLocationConfiguration,context=pjt001" - 你可以通过打开 VisualVM 或 JConsole 看到。

但是，即使定义了 MBean，问题的根本原因是您试图在init()加载上下文之前从方法访问它。

这是您的测试上下文的修订版本，它工作得很好，因为我删除了 MBeanExporter 中对 apploader 的引用，并将 appLoader 移动到 MBeanExporter 下方。

<bean id="mbeanServer" class="org.springframework.jmx.support.MBeanServerFactoryBean">
    <property name="locateExistingServerIfPossible" value="true"></property>
</bean>


<bean id="appConfigLocationMBean" class="org.springframework.jmx.access.MBeanProxyFactoryBean">
    <property name="objectName" value="test:name=appLocationConfiguration,type=SpringAppLocationConfiguration,context=pjt001"/>
    <property name="proxyInterface" value="com.my.config.app_loader.AppResourceLocationMBean"/>
</bean>

<!-- Enabling below bean and disabling the above bean worked for me. But need a proxy interface solution. -->
<bean id="actualAppConfigLocationMBean" class="com.my.config.app_loader.AppResourceLocation"/>       

 <bean id="mbeanExporter" class="org.springframework.jmx.export.MBeanExporter">
    <property name="beans">
      <map>
    <!--  Used to add additional application contexts at runtime. --> 
       <entry key="test:name=appLocationConfiguration,type=SpringAppLocationConfiguration,context=pjt001"
              value-ref="actualAppConfigLocationMBean" />
      </map>
    </property>

</bean>

<bean id="appLoader" class="com.my.config.app_loader.AppLoader">
    <property name="appLocationMBean" ref="appConfigLocationMBean" />
</bean>

但是，我建议在而不是在 中实现SmartLifecycle并进行查找，因为这样您就可以确定上下文中的所有 bean 都已初始化。start()init()
